Product Overview
The G818NC 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.
G818NC at a glance
Table working area 460×200 mm, lateral travel 540 mm, longitudinal travel 250 mm, grinding wheel Ø200*6-20*31.75 mm and spindle motor 2.5 kW.
Further key data: table load 150 kg; spindle speed 2850 rpm; machine weight 1400 kg.
Quality components
Key components come from established suppliers: FUKUTA (spindle motor); HORINSHENG (spindle); NSK (spindle bearings); Turcite-B (anti-friction material); HONGMING (hydraulic system); WEIKE (chuck); SCHNEIDER (contactors).
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.
