Surface Grinder

Surface Grinder
Model No. TH-M3270
Origin: China
Min. Order: Negotiable
﹣The vertical post of the machine is attached to the guide way, the balanced moving of the grinding wheel offer the fine precision of the machine.
﹣The guide way of cross travel is double “V”.A guide way of longitudinal travel is “V”, the other one is flat. The friction is small.
﹣Longitudinal, cross travel and spindle feed use hydraulic or manual driving.
﹣Spindle feed use microfeed set,the feed precision is up to 0.0002mm
﹣Japan made P4 precision spindle ball bearings are adopted for easy maintenance. The roughness of surface is smaller than Ra0.63.
﹣Logical controller that use programme controller combined with transducer to realize the machine auto feed, stepless and lubricate system offer oil periodicity.
﹣Auto feed realizing export contactless can be fit to feed and change direction frequently when manufacturing smaller workpiece with high dependability.
﹣Magnetizing and demagnetization controller realizing export contactless can be fit to magnetizing and damagnetic frequently, the time of demagnetization is short, avoid pulling and transfiguration of the electromagnetism chuck and workpiece.
