Thread Milling Machines

Model XKW185/1500


This machine incorporates milling head for high efficiently cutting external & internal thread, worm and so on.  It can cut thread rods and worms of single start and multiple starts, and variable pitch and diameter.  It can achieve high efficiency and surface finish better than turning by lathe.



Features:

High efficiency cutting with milling tool of multiple inserts cutter

Roughness as good as Ra 0.8 – Ra 1.25

Variable pitch of thread and variable diameter

Single start or multiple starts of threads

CNC control of C axis, Z axis, and X axis simultaneous motion

Internal milling disc or external milling disc supplied according to work requirement

Milling spindle variable speed control
