Manual Surface Grinders

Pinnacle horizontal surface grinding machines with manual table drive are designed with new concept having linear guideways for the easy table movement with wire rope drive to avoid pitch marks usually observed in rack and pinion drive (charter) on the job ground. Model GSM-4520 is available with table size 450 x 200 mm and GSM-4525 with table size 450 x 250 mm. The company also offers surface grinding machines in full range named as Sumo series, viz., GSH-50 Sumo with table size 500 x 200 mm, GSH-75 Sumo with table size 750 x 250 mm, GSH-100 with table size 1000 x 300 mm in hydraulic version and GSH-8 with table size 800 x 400 mm and GSH-8 Jumbo with table size 1000 x 500 mm in hydraulic as well as NC/CNC version and FASGM 10030 full automatic surface grinding machine and CNC 3X8040 grinding machines. Sumo series machines have robust base structure and have internationally accepted fixed column design. The heavy box type column casting with honey-combed ribbing is rigidly clamped to heavy base casting. The spindle housing supports cartridge type spindle unit and is assembled with super precision bearings grease packed with imported grease to have long trouble free service. The table drive is hydraulic with soft reversal device. The automatic electronic cross-feed is variable from 0.5 to 6.0 mm at each table reversal with safety manual to auto interlocking device. An automatic lubrication system is provided in longitudinal as well as transverse guide ways with separate controls to control the flow of lubrication oil. The machines are tested as per IS test chart. Flatness accuracy of within 10 micron and surface finish of within 0.4 to 0.8 micron RA are standard features.
