Joen Lih's High Precision ATDII Series, starting from JL-2550ATDII to JL-7040ATDII, have optimized structure and rigidity castings to ensure stable accuracy.
* X & Z axis travel on double V slide ways, coated with "Turcite B" and hand
scrapped to minimize the change of oil film on the track, ensure the stability
* High precision spindle: The cartridge-type spindle uses high precision P4
bearings and fully sealed grease lubrication. Long life and high precision!
* Precise infeed of vertical axis: linear guide way and ball screws are used
on vertical, improving the smothness of grinding and realizing better accuracy.
* Vertical is driven by AC servo motor, high torque, high speed and high
positioning accuracy. With automatic control system, the feed accuracy can
* Crisscross grinding: Continuous feed grinding in cross can cover a wide
grinding area, increasing grinding efficiency.
* Dynamic balance correction: adjusting the balance block can reduce the
vibration of grinding wheel, remove surface ripples of components.
* Ultra precision machinning and mirror finishing can be performed by
adjusting the environment. The flatness is with 1µm, surface rought with
