SGS Series High Precision Surface Grinding Machine
MAIN PURPOSE:
TECHNICAL CHARACTERS:
- Robust cast iron and stable structure for precision grinding
- Spindle grinding heads adopts super precision angular contact ball bearing
- Hardened and precision ground vertical lead screw & cross lead screw
- Hydraulic table and saddle movements reversible by proximity switch
- Machine guide ways are accurately hand scraped Automatic continuous lubrication on guideways and lead screws
- The easy to use, conveniently located operator panel includes all buttons and switches.
- The vertical In feed of grinding head is controlled by using the vertical motor for quick rising and lowering in (SHR series) or the servo motor for quick rising and lowering (SHD series), which can also be operated manually.
- Closed hydraulic system is adopted for the reciprocating the work table.
- Transverse movement of cross can be manually feed or the lead screw can be driven by the motor for automatic intermittent feed.
