Machinery & Equipment

Bearing special machine tool manufacture
Billon special machine tool can realize double processing at the same time and robot automatic up-down material . One clamping can complete bearing ring rough and finish machining . The machine is indispensable to bearing industry CNC equipment.
Mechanical Features
1. centre grind with multi-section changes structure & bed integrated design, the bed cavity is filling by shock proof material, Increased machine& acute;s rigidity and shock resistance.
2. X-axis use multi-guide way super-positioning layout, increased machine& acute;s rigidity and machining accuracy.
3. The spindle bearing use (4 in front, 2 back structure), increased spindle& acute;s rigidity ; shock proof ability; machining smoothness and accuracy.
4. The screw& acute;s diameter has increased 1.5-2 times, increased transmission power and mach inability.
5. The machine use front-chip conveyor which invented by Krupp, no damage to the overall rigidity, could install automatic chip conveyor.
6. The machine use fully enclosed protection, with elegant appearance.
7. with automatic lubrication device, maintenance-free.
