Hydraulic Static Bearing Design

The floating hydraulic bearing is designed with a heavy duty roller bearing.

Hydrostatic bearing design is revolutionary feature. In addition to superior resistance to heat
expansion, asymmetrical loading, and heavy duty cutting, this technology guarantees prolonged
machine servicing life and stability throughout all shifts.

The table is manufactured from high tensile Meehanite cast iron and built on a one-piece base casting
for maximum durability and rigidity, which surpasses many peer model’s two-piece base design.

RIGIDITY & CONSTRUCTION
Machine Construction

Detail, innovation, and capacity are put into practice in the RAL series Vertical Turning & Boring Lathe.
Massive ribbed box structure, hydrostatic bearing of table, and octagonal ram construction are all
integrated into the exceptional design of the RAL vertical lathes. The combined features and intensive
attention to detail enable the RAL VTL to perform in today’s most demanding applications.

Strong Meehanite cast iron single piece wall type column with ribbed box structure that provides
robust base for stability and rigidity

Heat treated, oversized box ways with 55 degree Rockwell hardness

Main Table Driven

Power is transmitted to the table
via a proprietary two step,
hydraulically shifted gearbox.

Maximum loading can reach
10,000kg on RAL-16; nearly
doubling competing models.

Specially designed 2 step gear
box to produce 18,790 Nm Max.
torque on a Fanuc α40/6000i
spindle motor.
Special Slant Saddle Design

The 15° slant saddle design is
applied on both RAL-16 and RAL20.

This reduces overhang problem
and provides increased machine
rigidity.

Ram Construction

Unique octagonal ram construction records
outstanding performance in terms of thermal
expansion control and straightness.

Octagonal design provides impressive, 23% more
clearance than square ram, through-hole
capacity to allow better clearance when boring a
deep hole in workpiece.

240x270mm ram cross sections to handle all
kinds of turning and cutting jobs.

Flexibility and availability of 90゜angular heads
(for models with C-axis) to complete
milling/drilling/tapping in a single setup

Balanced cutting power for cutting both internal
diameter(I.D.) and outside diameter(O.D.) with
two sets of clamping gibs to support cutting
stress from both directions. The result is equal
quality in terms of finishing surface and accuracy
for both I.D. and O.D.

RIGIDITY & CONSTRUCTION
Crossrail Slant and Locking

A 15゜slant bed design for the crossrail X-axis travel
is implemented for higher rigidity to heavy duty
turning jobs.

The height of cross rail is designed to be adjustable
according to workpiece geometries along an 800mm
W-axis travel with 5 positions.

Every position is locked by independent hydraulic
clamping cylinders plus large taper lock pins to
ensure maximum cutting safety. Each of the
engaging position is designed to take crossrail
rigidity to the next level. The combined features
strengthen machine’s side cutting capacity while
promoting repeatability and eliminating overhang
problems of tool ram. .

Drive System & Moglice Surface

The X and Z axes slide way are all hand scraped with MOGLICE coating material for perfect alignment
and friction-free movement.

This unique MOGLICE coating material, with 1:1 correct to the micron property, has a quarter less
friction than traditional Turcite B coating material. Therefore, it eliminates backlash and minimizes
wear problems happened in traditional box-ways machine as well as maintains long term accuracy.

The properties of MOGLICE :
-
Optimized Anti Stick-Slip
-
Perfect long term adhesion, no measureable shrinkage in more than 45 years
-
High dimensional stability
-
Excellent damping properties = improved stiffness
-
Good chemical resistance
-
Best coefficient of friction
-
Wear resistant
