Finished parts

【Main use】

The machine is mainly used for grinding screws with Whitworth & Acme thread and ball-screws precisely



【NC system configuration】

1、Equipped with a SIEMENS 828D CNC system,the machine is controlled with five programmable axes including three synchronous ones。

2、No. of Programmable axes

Axis Z:Table longitudinal traverse

(With grating scale)          full close-looped

Axis X: Cross-feed of wheelhead

Axis C: Rotation of work spindle

(With angular encoder)        full close-looped

Axis V: Vertical feed of dresser slider

Axis W: Horizontal feed of dresser slider

Out of above NC axes, C-axis and Z-axis are linked to perform thread movement;Wheel dressing is conducted by a formed diamond roller;Two electric hand-wheels can control each NC axis by hand。

【Working accuracy】

1、The accuracy of ball-screws can be reached to grade P2 (GB/T17587.3-1998) (ISO3408-3:2006) after ground。The dynamic measuring device is as the test tool for leadscrew

2、The accuracy of Acme screws can be reached to grade 6 (JB2886-1992) after ground

【Technical characteristics】

1、Employing a rear-mounted wheel spindle supported by hydro-static bearings,workpiece surface improves greatly。

2、The optimized workhead structure makes work spindle speed double,thus improving machine efficiency greatly。

3、The optimized CNC wheel dresser can dress grinding wheel into various required profiles

4、Oil chiller,high-flow and powerful cooling system and double-filtering system together ensure the temperature influence in grinding process to the minimum。

5、With the intelligent grinding software in man-computer interactive conversation,wheel dressing and grinding can be operated with convenience and accuracy。
