Product Overview
The G5012NC is an NC surface grinding machine with boxway guideways. Automatic down-feed, spark-out passes and fixed grinding cycles give repeatable results with less operator intervention.
G5012NC at a glance
Table working area 1200×500 mm, lateral travel 530 mm, longitudinal travel 1340 mm, grinding wheel Ø355(400)×20~40×Ø127 mm and spindle motor 7.5 KW.
Further key data: table load 1000 kg; spindle speed 1450 rpm; machine weight 5500 kg.
Quality components
Key components come from established suppliers: FUKUTA (spindle motor); HORINSHENG (spindle); NSK (spindle bearings, ball screw bearing); SYNTEC (controller, servo motor); Turcite-B (anti-friction material); HONGMING (hydraulic system); WEIKE (electromagnetic chuck).
Boxway rigidity
Box guideways spread the cutting load over a large contact area, which gives high damping and stable grinding. Combined with a servo-driven vertical axis, this allows precise stock removal down to the final size.
Easy, repeatable cycles
The NC control handles rough and finish feed, spark-out passes and rapid approach automatically, so one operator can run several machines.
