Taiwan Takisawa Ltd, Co.

LA-450Y

The LA-450 series is a new generation high precision heavy duty turning center developed for highly precise machining through its extremely strong and rigid structure and high-precision machining of large diameter workpieces.
Largest spindle bore bar stock diameter increased to Ø150. The 2-step gear box provides extra high torque during low speed machining for outstanding heavy cutting performance.

Specification

Spindel

Taiwan Takisawa home-made spindle equipped with high rigid spindle structure supports resistance to deformation, powerful machining capability and solid durability.
For LA all models equipped with gearbox, the gears are all with 0-grade ﬁne ground precision.
The gearbox allows cutting at high torque in low speed range, combined with a highly accurate ﬁnish surface.

Turret

The high performance turrets are also home-made by Taiwan Takisawa, the two-piece high precision coupling provides not only high clamping force, but also rapid and accurate indexing. It’s easy to calibrate positioning in both the CW and CCW direction.
We can provide a customized needs assessment for special needs regarding numbers of tools, tool holders, milling cutters etc.

Tailstock

Taiwan Takisawa home-made tailstock with high thrust and strong clamping force ensures maximum stability especially when working with long workpieces. The movement of tailstock body is carried by turret with easy positioning feature, the tailstock quill is available in ﬁxed and rotary versions and the tailstock is pushed by hydraulic.
Special needs such as thrust size or quill form etc. can be assessed if customization is required.
