China Saddle Moving Surface Grinding Machine

Surface Grinding Machine (SGA2550AHR)
Hydraulic movement on X--AXIS,
Rapid moving on Z--axis.
Saddle moving.
Designed for continuous operation at maximum speed, very quiet operation, maximum accuracy and minimal heat accumulation ensure optimum machining results.
Grinding spindle runs in maintenance-free preloaded precision angualr ball bearings
Automatic transverse and longitudinal feed
Rapid feed for setup to desired work height(HFS VC)
Adjustable roughing, finishing, and spark-out strokes hydraulic longitudinal table movement on Y axis(HFS VC)
Double tabe V-guide in transverse table, V-guide and flat guides in longigudinal table
Table guideways are hardened, ground, and PTTE (polytetrafuorethylene)counterlaminated-ensuring maximum wear resistance
High table load capacity for heavy parts
External hydraulic unit ensures high temperature stability
Automatic central lubrication
