maximum accuracy and minimal heat accumulation ensure optimum
machining results Grinding spindle runs in maintenance-free preloaded
precision angular 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 table V-guide in transverse table,
V-guide and flat guides in longitudinal table
Table guide ways are hardened, ground,
and PTFE(polytetrafuorethylene)counterlaminated-ensuring maximum wear resistance
High table load capacity for heavy parts
External hydraulic unit ensures high temperature stability
Automatic central lubrication
AH: Auto cross feed, hydraulic longitudinal feed, manual vertical feed
AHR: Auto cross feed, hydraulic longitudinal feed, rapid vertical feed
AHD: Auto cross feed, hydraulic longitudinal feed, automatic vertic feed
