Linear Scale (Optional)
The X,Y,Z- axis are available to equip with high precision linear scales, providing a closed loop control. This effectively upgrades positioning accuracy on the three axes. High Precision Spindle.
Extremely Stable 4-box Way Base
The massive bed construction, combined with 4-box way design provide firm support for the entire machine.Also, guarantee the maximum structural rigidity and stability.
Oversized way surfaces and extra large span between ways for greatly upgrading the machine stability.
Way surfaces are hardened and precision ground, assuring maximum wear, resistance and smooth motion
 
Rigid Spindle Stock
The one-piece fabricated spindle stock is manufactured from high quality cast iron. The ruggedly constructed spindle stock assures vibration-free performance during grinding operation.
The spindle vertical travel is well balanced by a counter-balance weight for outstanding smoothness and stability of movement.

Advanced CNC Control
The machine is equipped with the latest CNC control with teach-in programming and is easy to operate.
Machining programs are automatically generated through graphic dialog.
This greatly saves on preparation time while increasing efficiency.


Control System Meets European Standards
The control system consists of top quality electronic components which comply with European safety requirements.
The interior of control cabinet is dust-proof and fluid-proof.
The control system has a self-diagnostic function and warning light for clear identification.

German IMT Spindle
The spindle speed is specified by customer.
Maximum spindle speed is up to 140,000 RPM.

Rotary Table (Optional)

Equipped with D.D. motor to ensure the best circularity and motion smoothness.

Max. rotary table diameter is 500 mm.

Movable Coolant Tank

The front mounted, moveable coolant tank is easy to clean or replace coolant.

The coolant system employs a special high pressure coolant pump, featuring excellent cooling and chip flushing.
