Prompts and Error/Status Area
The bottom portion of the screen is reserved for prompts, program status and error
messages.
Prompts provide help on data entry selections based on the field with the blinking cursor.
Errors and status messages can occur anytime the status or error is true. They are not
based on the field with the blinking cursor. These messages provide machine information
to the operator and error messages may also stop and/or prevent machine operations. An

Lathe Maintenance and Safety Manual
Closed loop servo drive systems and motors with rotary encoders power the mechanical
drives that position the axes. The rotary encoders provide positioning feedback
information to the control. Limit switches mounted on each axis determine end-of-travel
and establish reference points for initial machine zeros.
The control positions an axis by sending a command to the appropriate servo drive, which
in turn supplies voltage to the connected axis servomotor.
Refer to the Parts Listings and Wiring Diagrams Manual for mechanical and electrical
component drawings for your machine.
Machine linear positioning accuracy was set at the factory, in an
ambient temperature of 68º F (20º C). Continual operation at
higher or lower temperatures may require that you recompensate the linear positioning accuracy.
The TM6, TM8, and TM10 machines are described in this manual.
Frame
The major structural assemblies of each Hurco machine are constructed of thick-walled,
fine-grain cast iron. This construction provides strength and excellent dampening
characteristics, keeping deflection and resistance at a minimum during turning.
The machine base (including leveling bolts) is the substructure for the column and table.
The column is a rigid box type, and allows for machining a variety of part sizes. The base
supports the table and preserves “table flatness.”
Head
The cast iron head assembly is designed to produce superior cutting accuracy.
Guideways
The X and Z axes guideways are oversized, precision linear rails.
Switches and Sensors
Limit switches, proximity switches, and electrical sensors monitor machine functions.
These devices report their state to the control. If a malfunction is detected, a stop
condition will shut off power to the servo systems and spindle.

Lathe Maintenance and Safety Manual
Servo Motors
The CNC controls axes velocity and travel direction using AC servomotors. These motors
are enclosed, transistor-driven, and self-cooled. Because they are designed without
brushes, the motors are free from flashover and commutation loss.
Ballscrews and Bearings
The precision ballscrews are the double ballnut type. The ballscrews are hardened and
ground to minimize “drag torque” and reduce backlash.
The axes positioning drives are supported at the drive-ends by ABEC-7 class bearings.
Feedback Systems
Each drive has circuitry to detect conditions in the servo’s closed-loop system.
Each axis motor is equipped with a rotary encoder that provides velocity and position
feedback signals for each closed-loop system. These signals are required for motor
control and accurate positioning.
Limit switches mounted on each axis are used to establish reference points for initial
machine zeros and for determining end-of-travel.

Machine Electrical Cabinet
The machine’s electrical control cabinet contains CNC-related electronics and powerrelated circuitry.
Safety Procedures for Electrical Service
Before removing or working on any printed circuit board (PCB), cables, fuses, breakers,
or other machine components, make sure that the main disconnect switch on the
electrical cabinet door is in the OFF position. Whenever work will be performed in an area
away from the main disconnect switch, post a warning at the switch informing others that
the machine is being serviced and the power must remain OFF.
High voltages inside of the electrical cabinet can cause serious injury
or death. Only qualified personnel may service the machine, and
must follow all safety rules and precautions. The line-side of the
main disconnect switch is hot, unless the AC source is disconnected.
Handling Printed Circuit Boards
The following procedures should be taken to prevent damage when removing printed
circuit boards (PCB), or when checking the boards for proper and secure connections.
Avoid flexing PCBs. Rough handling can result in hairline cracks in the printed circuit
etching. Problems caused by cracks in PC boards can be hard to isolate. Avoid touching
the components on a PCB because they can be damaged by static electricity.
•
Always put on a static safe handling wrist strap before touching PCB
assemblies inside the cabinets, and before removing replacement boards
from their static protective packaging.
•
Visually inspect the wrist strap every time you put it on, making sure that the
snap fasteners are properly connected.
•
Be sure the strap fits snug to the wrist. Taking off the wrist strap should be
the last thing you do when finished inside the cabinet.
•
After the replacement PCB is properly mounted in the cabinet, place the
defective PCB assembly into the static shielding and return to Hurco.

Lathe Maintenance and Safety Manual
Electrical Cabinet Components
The electrical cabinet contains power circuitry and CNC electronics. The cabinet is
attached to the machine column and connects to the machine systems via cable and
harness assemblies.
Power-related circuitry distributes power, while CNC-related electronics control machine
operation (e.g., spindle speed and axis positioning).
Electrical Cabinet Operating Temperature
The electronics inside of the electrical cabinet are designed to tolerate reasonably high
ambient temperatures. Fans on some of the electronic assemblies and a heat exchanger
on the cabinet door circulate warm air away from components.
The cabinet contains a temperature sensor, mounted on the CANbus control board in the
ISA control board rack. This sensor is preset to a high temperature limit. If the
temperature exceeds the limit, the machine will enter an emergency stop condition.
Hurco Turning Centers that are not equipped with the air conditioning option may be
operated in ambient temperatures up to 95º F (35º C), and in relative humidity (noncondensing) up to 95%.
Electrical Cabinet Layout
Electrical cabinet layouts may vary from machine to machine. See the Parts Listings and
Wiring Diagrams Manual for your machine model.
Power Supply
The DC switching power supply mounted on the ISA control card rack converts the 115
VAC input power to the regulated DC voltages distributed by the DC distribution board.
The DC distribution board supplies regulated DC voltages to all printed circuit board
assemblies in the card cage, console, and control relays.
Lathe Maintenance and Safety Manual
704-0214-201
Machine Components 1-13
CNC Electronics
The primary CNC-related PC boards that are located in the machine’s electrical cabinet
are described below.
ISA Control Card Rack
The ISA Control Card Rack contains the following microprocessor control PCBs:
•
Main CPU (Single Board CPU and Passive Backplane)
•
Peripheral Interface
•
Dual VGA Board
•
Motion Controller
•
CANbus Controller
•
CANbus DC I/O Backplane
•
I/O Interface
Main CPU Board
The main CPU board is a single board computer with a microprocessor CPU.
The CPU board uses a passive backplane that provides both ISA and PCI buses, and is
jumper-configurable to permit system performance enhancements. Since the board’s
memory requirements are based upon the application requirements, memory is
upgradeable.
Peripheral Interface
The control supports standard AT-compatible peripherals including:
•
Hard disk
•
Serial interface—COM1
•
Floppy disk
The interface for the hard disk is an integrated disk electronics (IDE) interface. It is
considered integrated because the hard disk controller resides on the drive itself and the
interface resides on the motherboard. The connector for this interface is typically a dual
row, 40-pin header.
The main CPU board supports a standard, 34-pin, PC/AT style, floppy disk interface. The
base level system has at least one 1.44 MB drive.
VGA Board
The VGA board enables the CPU board to display text and graphics on the display. The
VGA board connects to the CPU board via the PCI bus.

704-0214-201
Lathe Maintenance and Safety Manual
Motion Control Board
The motion control subsystem uses a PCI servo transducer card to pass velocity
commands from the soft motion system to the servo drive and spindle pack. The
transducer card also converts A quad B encoder feedback to position data that in turn is
read by the motion software. The PCI servo transducer supports S, X, Z, C, Y, and S axes.
CANbus Controller Board
The CANbus is a multi-master serial bus developed for the controller area network (CAN).
This bus is the input/output (I/O) center of the Ultimax ISA platform.
The CANbus controller board and the DC I/O interface board handle the I/O control
functions within the CNC controller. The external node used by the machining center is
the console interface.
The CANbus controller board is an intelligent AT bus board for executing logic control
programs, controlling CANbus I/O, controlling local 24-volt I/O, and monitoring the onboard A/D converter.
CANbus DC I/O Backplane
The CANbus DC I/O backplane distributes power and CANbus signals to the I/O interface
board. The basic voltage levels are +5VDC, +/-12VDC, +24VDC. There are three isolated
grounds: digital GND, machine GND, and analog GND. The backplane slot determines the
node address of the board.
I/O Interface Board
The CANbus I/O interface board forms the interface between the motion subsystem and
the CANbus controller I/O. The I/O signals on this board are buffered and then routed
within the enclosure over a ribbon cable to the motion or CANbus subsystems. The board
uses Honda connectors.
CANbus DC I/O Node
The CANbus DC I/O Node board mounts on the CANbus DC I/O backplane in the
extension enclosure to the ISA card rack. This board communicates with the machine
through 32 input and 32 output connections, and transfers information through the
backplane to the CANbus controller.
The 24 volt solid state outputs are current limited to 150mA. Outputs are disabled at
power up and when the E-Stop button is depressed.
Multiple boards may be used to provide additional I/O. The extension enclosure accepts
two of these boards in addition to the I/O interface board; all are connected to the
CANbus DC I/O backplane. Expansion for other boards is possible.

Operation Requirements 2-1
Safe Installation of Guarding System and
Machine
Inspect the machining center to ensure that all parts are included and intact. The owner
is responsible for proper site preparation before the machine is installed. A Hurco Field
Service Engineer must install the machine in the prepared location. This location must
not subject the machine to uncontrolled cabinet temperatures or unfavorable work
environment conditions that could cause electronic component failure.
If the owner decides later to move the machining center from its installed location, it is
recommended that the owner call Hurco for assistance.
Improper moving of the machine may result in personal injury or
damage to the machine.
Each machining center has a self-contained guarding system. Inspect the machine to
ensure the guarding system is intact. The chip doors on the front of the machine lock
during Automatic Run Mode to prevent access to the moving parts of the machine.
Safety Circuits
If the owner or operator modifies the hardware or software by removing, altering,
disabling, or tampering with any safety circuit, safety switch, or other safety operation
and operates the turning center with those modifications, such operation is extremely
hazardous and is a foreseeable misuse of the machine, and voids the Hurco warranty. If
such modifications are discovered, the turning center must be immediately shut off and
not used. Contact a Hurco-Certified Engineer for assistance in restoring the machine to
safe operation.
The Hurco turning center’s safety circuit is designed to provide safe and reliable
operation. Tamper-resistant fasteners are used to hold combination door lock/switches in
place and to prevent access to internal wiring. Here are basic rules governing operation:
•
The spindle cannot operate unless all enclosure doors are closed, excluding
doors that are fastened shut with bolts or screws.
•
Enclosure doors must be closed and locked during automatic execution,
warm-up cycle, calibration cycle, automatic tool changes, probing, or when
running the spindle.
•
In the event that the enclosure door is opened during automatic operation, or
any time the doors are locked, an immediate command to stop all motion will
be executed and control power will be removed.
•
Redundancy is included in electrical design to detect single point failures.
•
When the Emergency Stop button is pressed, power is cut off to the spindle,
after allowing for deceleration.
•
Turret electrical circuits will be isolated from source power when any door is
open.

Machine Maintenance 3-5
If the machine will be idle for 30 days or more, add a rust preventative to the system
lubrication. Initiate a manual lube cycle and move all axes for full travel several times to
allow delivery throughout the system.
Excess servo On time without table or head movement may cause oil
to accumulate on the table and guideways. To eliminate excess
lubrication, the Power Off Timer can be set to automatically shut off
power to a machine that has been idle for a specified time.
The oil filter strainer prevents contamination from entering the system. The strainer must
be checked periodically, and replaced if it becomes plugged.
Check Filler Screen and Fluid Level
Maintain the fluid level and check the filler screen:
1. Lift the oil filler cap and check that the screen is clean. Clean and dry the
screen before reinstalling it.
2. If needed, add oil to the tank. The level should be between the high and low
marks (about 1/2 inch or 1.27 cm from top cover of tank). Replace the fill cap.
Activate System Manually
If the machine has been idle for a long time before powering up, or if the oil has just been
replaced, follow these steps to manually activate the Autolube system:
1. Pull upward on the discharge plunger, then release it.
2. Stroke the plunger in this manner three to six times.
Adjust Autolube Discharge Rate
An indicator rod is located in the Autolube system’s discharge chamber. The scale
graduations on the flat surface of the rod indicate the discharge rate in cubic centimeters
(cc) per pump cycle. To adjust the discharge rate of the Autolube system, follow these
steps:
1. Loosen (but do not remove) the setscrew in the center of the discharge
plunger body.
2. Turn the plunger body clockwise to increase or counterclockwise to decrease
the pump discharge rate.
3. Once the required discharge rate is obtained, align the setscrew with the flat
surface on the rod. Tighten the setscrew to secure the rod position.

Refer to Chuck Hydraulic Pressure Gauge Settings, on page 4 - 10 for
information about setting the hydraulic pressure for the chuck.
•
Refer to Tailstock Hydraulic Pressure Gauge Settings, on page 4 - 17 for
information about setting the hydraulic pressure for the optional tailstock.
•
Refer to Turret, on page 1 - 21 for information about setting the hydraulic
pressure for the turret.
Coolant System
The flood coolant system pumps coolant to the tool in the turret.
Used coolant is cleaned of chips and oil and recirculated into the coolant tank. Filters
remove contaminants from the coolant.
Selecting Coolant
Coolant should have these qualities:
•
Suitable for the work piece material and machining operation.
•
Soluble in water.
•
Mineral content of at least 35%. When synthetic coolants and coolants that
contain too little mineral oil contact guideway lube oil, they can gum the
guideways.
•
Adequate rust protection.
•
Anti-foam, anti-bacteria, and anti-fungi agents.
•
No skin irritation when prepared to the manufacturer’s specifications.
•
Penetrating lubrication oil should float on the surface of the coolant (instead
of dissolving in the coolant).
3 - 8 Machine Maintenance
704-0214-201
Lathe Maintenance and Safety Manual
•
Use the recommended coolant to prevent damage to the machine’s oil,
guideways, precision ballscrews, and painted surfaces. Use a non- or semisynthetic water soluble coolant.
•
Failure of devices or performance problems related to coolant are not a defect
in Hurco’s material or workmanship, and will not be covered by Hurco’s
warranty.
Preparing Coolant
Follow these guidelines when preparing coolant:
•
Mix the coolant according to the manufacturer’s instructions. Use deionized
(preferred) or softened water for the coolant mixture. To prevent zinc
contamination, do not store coolant in a galvanized container.
•
Check coolant concentration regularly with a refractometer, or by titration.
•
Screen off any residue floating in the coolant.
•
Use coolant additives, such as bactericides, and anti-foam corrosion agents,
only if recommended by the manufacturer.
•
Do not allow foreign matter to mix with the coolant. Contaminated coolant
can damage machine parts.
Maintaining the Coolant
Check the coolant level every day at the start of operation. If the machine is used more
than 8 hours daily, check the coolant level every 8 hours. Find the level indicator on the
coolant tank and maintain the level as follows:
1. If the flood coolant pump is off, then fill the coolant to the H (High) mark. Note
that the machine should be off for at least 5 minutes before filling the tank
with coolant.
2. If the flood coolant pump is delivering coolant to the machine, then fill to the
MAX mark.
If the coolant level drops below the L (Low) level mark on the coolant
tank, the coolant system may not operate properly.

Machine Maintenance 3-9
Replacing Coolant
To replace coolant, follow these steps:
1. Using a suitable brush, remove chips and other debris from the enclosure (and
chip conveyor, if installed).
2. Drain used coolant from the system and tanks.
3. Clean, or change, pump filters and pick-up tubes.
4. Fill the coolant tank with a neutral aqueous cleaning agent and flush
thoroughly.
5. Drain the cleaning agent.
6. Rinse the system thoroughly with a 1% coolant solution. If bacteria or fungi
contaminate the system, use a cleaning agent recommended by the coolant
manufacturer.
7. Drain the rinsing solution.
8. Dispose of used coolant and cleaning solution in compliance with applicable
pollution control regulations.
Limit Switches and Dogs
Limit switches and dogs are mounted on each axis. To determine end-of-travel and to
establish reference points for initial machine zeros,
1. Open the rear-access panel above the hydraulic pump so you can see the limit
switches and dogs.
2. Use the jog unit to position the axes at mid-travel.
3. Check the tightness of limit switch and dog fasteners.
Machine Electrical Ground
The machining center’s ground is located inside the control cabinet, near the disconnect
switch. A licensed electrician should measure the ground impedance (resistance to true
earth) every three months.
Machine Level
Inspect the machine’s level every six months by placing a precision level (resolution
0.0005 in/ft.) parallel and perpendicular to the leveling plate that bolts onto the turret.

Tool Setter Maintenance
The tool setter needs to be calibrated before its initial use. After that, you only need to
re-calibrate as necessary.
Tool Setter Calibration
The tool setter calibrates the X and Z axes by touching off the part using tools in the
turret. You can calibrate the axes in any order (X first, then Z; or Z first, then X).
•
Use a test bar (i.e., a dowel pin or precision tool shank) and a boring block of
the same diameter for calibrating the X axis.
•
Use a test plate, secured with a magnet if possible, for calibrating the Z axis.
Stylus Alignment
The tool setter stylus needs to be aligned correctly. To align the stylus,
1. Loosen the screw at the base of the stylus to adjust the height so the tip of the
turning tool is centered vertically on the stylus head.
2. Tighten the screw when the stylus is positioned properly.
