Surface Grinder G-3A3060
Extra large oil tank and double pumps design provide effective cooling to the motion friction heat and improve the circulating lubrication. The built-in switch box not only protects the electronic components, but also prevents the coolant from entering.
The column is an oversized and increased height construction. The honeycomb structure may reduce resonance in heavy duty machining. Powerful 7.5HP spindle motor provides better grinding capability and higher efficiency. The micrometric adjustment device is easy to operate with graduation in 0.001mm.
The cross feed is transmitted through a high precision ball screw, assuring high accuracy of feeding and smooth movement. -
