Machine features 1. This series is a variation of MG2932B. The movement of quill is driven by AC motor through ballscrew. The grinding method is wet grinding which is more adaptive for machining shop.2. Linear rolling guideway are adopted on X, Y, Z-axis, which improve the production and accuracy as well as rigidity and vibration resistance. At the same time planet spindle and quill diameter are improved.3. The stroke of machine is driven by a module control servo motor through ballscrews.4. The grinding method is wet grinding It is convenient for the user to adopt diamond wheel to grind ceramic workpiece. |
