Product Name: Surface Grinding Machine (TH-M3270) Model NO.: TH-M3270 Variable Speed: With Variable Speed Working Style: High-speed universal Disc(Wheel) Type: Grinding Disc Power Source: Hydraulic Type: Surface Grinding Trademark: Townhero Origin: China Product Description 1. Japan made P4 precision spindle ball bearings are adopted for easy maintenance.2. Longitudinal and cross turcite-coated guide ways guarantee flexible operation.3. Longitudinal travel of the working table use hydraulic or manual driving, one guide way is "V", the other one is flat way.4. Cross travel use electromotion or manual motion driving, the guide way is "V".5. Logical controller that use propramme controller combined with transducer to realize the machine auto feed, stepless and lubricate system offer oil periodicity.6. Auto feed realizing export contactless can be fit to feed and change direction frequently, when manufacturing smallwe workpiece with high dependility.7. Magnetizing and demagnetization controller relizing export contactless can be fit to magnetizing and diamagnetic frequently, the time of demagnetization is short, avoid pulling and transfiguration of the elemagnetism chuck workpiece.ModelTH-M3270Working table size (LxW)700x 320mmMax. longitudinal travel of the working table800mmMax. cross travel of the working table370mmMax. distance from spindle axis to table surface600mmMax. load including electromagnetism chuck300kgsWorking table T slot18x 1mm x NWorking table speed2 ~25m /minCross auto feed0.04~10mmCross rapid moving speed1000mm /minCross feed on hand wheel1 gra.0.02mm1 re.4mmSpindle rapid vertical feed1500mm /minSpindle speed1 gra.0.005mm1 rev.2mmWheel rotate speed1 gra.1450r/minWheel size350x30x 127mmSpindle motor4kwWorking table hydraulic motor3kwHydraulic auto motorAC 40V 5AVertical feed motor250wCoolant motor40wFlatness of the workpiece0.005mmSurface roughness of the workpieceRa0.63Overall dimensions (LxWxH)2160x1900X 1970mmPacking dimensions (LxWxH)2300x1950X 2210mmN.W./G.W.2600/2900kgs
