Wedge-shape
oil film
Contracted film
10-station turret (standard) enables tooling diversity.
Sturdy box way
The box way glides on a dual-layered oil film,
wedge-shaped on the top and laminar on the
bottom. The wedge-shape improves sliding the
faster the box way moves, which extends the
service-life of sliding surfaces under a constant
load. Under fluctuating load, the laminar layer
acts like a cushion and laterally disperses and
dampens the impact force along the slideway.

colors and configuration shown in the photographs or illustrations may differ from those of the actual product.
OP
Raised coolant temperature causes thermal displacement in the fixtures and workpiece, affecting the machining accuracy
of the workpiece. Use this unit to prevent the coolant from heating up. When using oil-based coolant, the coolant
temperature can become extremely high even with the standard coolant pump, so please be sure to select this unit.
When using oil-based coolant, please be sure to consult with our sales representative.
●　While
this unit is not the only way to completely control the temperature of the coolant, it makes a major contribution to preventing increases in the oil temperature.

Short: chips 50 mm (2.0 in.) or less in length, bundles of chips A 40 mm (A 1.6 in.) or less
Long: bigger than the above
●　The options table shows the general options when using coolant. Changes may be necessary if you are not using coolant, or depending on the amount of coolant, compatibility with machines,
or the specifications required.
●　Please select a chip conveyor to suit the shape of your chips. When using special or difficult-to-cut material (chip hardness HRC45 or higher), please consult with our sales representative.
●　Chip conveyors are available in various types for handling chips of different shape and material. For details, please consult with our sales representative.
