Products Structural Performance
Production Line Interface
Overall structure, which can flexibly expand automation options.
Production Line Interface
Overall structure, which can flexibly expand automation options.
Turret
Circular arc tooth structure, with high precision, no tool lifting during tool change, fast servo tool changing speed, and strong rigidity of hydraulic locking.
Saddle
Triangular support structure, with better X-axis stability, higher precision, and faster speed.
Spindle
Integral spindle structure, large support span, good stability, supported by 6 rows of precision bearings, good rigidity and high precision.
Bed
Integrated bed structure, better Z-axis stability, higher precision and faster speed. HT300 castings, bed aging, and more durable precision stability.
Rich Modular Selection and Matching
Feeding/delivery devices, side/rear chip removal, tool setters, position detection, high-pressure cooling oil mist collection, in-machine spraying, special protection automation selection and matching, etc.
