G618 Saddle Type Surface Grinding Machine: table working area 450×150 mm, longitudinal travel 475 mm, cross travel 160 mm. Request a quote.
The G618 is a saddle-type surface grinding machine for precision flat grinding. The wheelhead moves vertically on the column while the saddle and table carry the workpiece, a proven layout for toolrooms and production shops.
Table working area 450×150 mm, longitudinal travel 475 mm, cross travel 160 mm, grinding wheel Ø180 mm×6-18×Ø31.75 mm and spindle motor 1.1KW.
Key components come from established suppliers: HORINSHENG (spindle); XINSHENG (spindle motor); NSK (spindle bearings); Turcite-B (anti-friction material); SHILIN (contactor); SIMPO (lead screw); WEIKE (permanent magnet chuck).
A heavy cast-iron base, hand-scraped guideways and a high-precision spindle deliver flat, parallel surfaces with a fine finish. Hydraulic table movement and automatic cross feed make long grinding jobs easier for the operator.
Machines are typically delivered with a grinding wheel and flange, wheel balancing equipment, a diamond dresser and an electromagnetic chuck, so you can start production quickly.
Table working area 450×150 mm, longitudinal travel 475 mm, cross travel 160 mm, grinding wheel Ø180 mm×6-18×Ø31.75 mm and spindle motor 1.1KW. The full data is in the specification table on this page.
Standard accessories include grinding wheel with flange, diamond dresser, leveling pads and anchor bolts, tool wrenches, toolbox and flush / vacuum cleaner.
