Surface grinding machine ETLD series

for large workpiecescolumn typewith magnetic chuck

Overview
The Double Column Type Surface Grinding Machine is powerful and suitable for large surface grinding. Designed and made as high-elasticity structure suitable for large surface grinding with more than 800mm of working width that cannot be ground by single column type. Box structure castings for extreme rigidity with no weight overhang. Turcite-B coated slide ways. Double cylinders and unique design of hydraulic system for table movement. Hardened & ground guideways of cross-rail and elevation ways. AC servo motors with precision ball-screws effect rapid elevation, automatic down-feed and up & down jogging for both horizontal and vertical spindles (optional). Double row roller bearings and angular contact ball bearings used for horizontal spindle, greased for life time. Modern 10-inch color LCD touch screen panel, simply touch the screen to set the grinding variables. Manual Pulse Generator (MPG) for both down feed and cross feed, including the infeed of diamond dresser. The crossfeed travel is set by the push-button on the console; different crossfeed increments can be set for rough and finish grinding separately.
