High Precision

PUMA ST16/20/32 series

High precision is implemented with the integrated bed structure optimized by FEM structural analysis and minimized thermal error

* FEM: Finite Elements Method

Optimized Design

Core units including the bed, the column, and the slide are designed with the highest stiffness in its class by 3D CAD technology.

Super precision Control and Tuning

• High precision machining is implemented by using optimized tuning technology and super-precision control function by IS-C (1/10000 mm).

• High speed, high precision machining is achieved by advanced control

Spindle Oil Cooling

The Spindle Oil Cooling System* cools down the spindle bearings and built in motor, thus minimizing thermal deformation.

Oil Cooling System for Main Spindle

Design with Minimized Thermal Error

Thermal error is minimized by using a symmetric, integrated structure, and an optimal rotary tool thermal displacement system.Both ends of the X2 and Y-axes ball screws are supported to minimize thermal error during long operation periods

Y and X2 axes transfer ball screws supported at both ends
