Finished parts

【Main use】

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

【NC system configuration】

1、There are four programmable axes controlled by the SIEMENS 828D CNC system,including three synchronous ones。

2、No. of programmable axes

Axis Z: Table longitudinal traverse

(With grating scale)          full close-looped

Axis X: Wheelhead cross feed

Axis C: Rotation of work spindle

(With angular encoder)        full close-looped

Axis V: Vertical feed of dresser slider

Out of the above NC axes,C-axis and Z-axis are in a gang to make thread movementTwo electric hand-wheels can operate each NC axis by hand

【Working accuracy】

1、Ball-screws:P3 (GB/T17587.3-1998) (ISO3408-3:2006), measured under dynamic state

2、Acme screws:P6 (JB2886-92)

【Technical characteristics】

1、Employing a hydro-static bearing wheel spindle,the workpiece surface is greatly improved。

2、The optimized workhead structure doubles workpiece speed,thus increasing the machining efficiency greatly。

3、By the inteligent grinding software in man-computer interactive conversation,different wheel profiles and workpieces  profiles can be achieved conveniently。
