G408K Saddle Type Surface Grinding Machine: table working area 800×400 mm, longitudinal travel 880 mm, cross travel 450 mm. Request a quote.
The G408K 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 800×400 mm, longitudinal travel 880 mm, cross travel 450 mm, grinding wheel Ø355×38×127 mm and spindle motor 5.5 kW.
Further key data: table load 700 kg; spindle speed 1450 R.p.m; machine weight 3000 kg.
Key components come from established suppliers: FUKUTA (spindle motor); HORINSHENG (spindle); NSK (spindle bearings, screw bearings); JUNCHUNSHING (hydraulic valves); Turcite-B (anti-friction material); HONGMING (hydraulic system); WEIKE (electromagnetic 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 800×400 mm, longitudinal travel 880 mm, cross travel 450 mm, grinding wheel Ø355×38×127 mm and spindle motor 5.5 kW. The full data is in the specification table on this page.
Standard accessories include wheel balancing stand, grinding wheel with flange 1, diamond dresser 1, wheel balancing rod 1, leveling pads and anchor bolts 1 and tool wrenches and toolbox 1.
