CNC OUTER TRACK (CROWNED) SUPERFINISHING MACHINE

FOR ROLLER BEARINGS

 

 

Main Applications
Outer track (crowned) superfinishing for single/double row cylindrical and tapered roller bearings.
 
Main Features
1. Implemented with Japan's FANUC all digital servo system (2-axis) with color display, "man-machine conversation" interface, manual pulse generator and self-diagnostics, the control system is stable, reliable, easy to maintain and convenient in adjustment.
2. Work spindle drive and oscillation slide motors are speed-variable with F.C.
3. Workpiece is gripped with an electromagnetic centreless chuck, supported by idle wheels and held on end-face also by idle wheels.
4. The stone oscillation slide is driven by servo motor and guided by cross roller guideway (THK make).
5. Automatic loading and unloading manipulator is stable, reliable, versatile, easy to adjust and free from dent mark on workpieces.
6. The moving trace of the stone can be set according to processing requirements to maintain the geometrical profile of the workpiece to its pre-honing shape.
7. The surface visual quality is excellent and even in color.
8. 3MZ3410CNC has two stations for rough honing and fine honing respectively. 3MZ3416CNC, 3MZ3420CNC, 3MZ3425CNC, 3MZ3435CNC and 3MB3445CNC use one-station-two-steps technology in which the rough honing and fine honing stones can be automatically indexed.
9. Filtration system for cooling liquid uses magnetic+honeycomb type filter or magnetic+non-woven filter cloth.
10. Machine is operated by pneumatic or hydraulic system.
11. Centralized lubrication system provides timing, quantitative and duly lubrication of ball screws.
12. High grade cast-iron machine body with double aging treatment assures the overall accuracy performance.
13. Painted and enclosed machine guard is nice looking and splash-proof and has a long service life.
