High-precision outer diameter machining of non-circular shapes

Features

Synchronizing the Y-axis slide and main axis driven by a linear motor enables high-speed, high-precision machining of non-circular shapes.
Tail thrust is torque controlled, thrust changes are done via CRT input
Vertical space saving: Floor space of 2.0 m2 achieved
Linked lathe machining ←→ non-circular machining. Realizes cycle time reduction.
The software allows you to easily create machining programs by inputting data into a computer.
Processing position
Y-axis unit for external finishing

Adoption of linear motor drive
Pursuit of zero backlash
Follow-up at spindle speed of 4,000 min-1
Maintaining high accuracy for a long period of time
Eliminate thermal displacement caused by temperature changes
By changing the Y-axis slide to a ball screw type and expanding the range of motion, it is possible to process eccentric parts with one chuck.
