(Note: The size of chisel edge of point angle depends on the screw above the dead center grinding hole of grinder, which can be adjusted the size. Also the adjusting range depends on the diameter of the drill bit.)Continue reading→

The importance of CNC machine tool and its development history

One of the most basic concepts in advanced manufacturing technology is numerical control (NC). Before the advent of CNC machines, all machine tools were operated and controlled manually. In many of the limitations associated with manual control of machine tools, there may not be a more prominent restriction than operational skills. Under manual control, product quality is directly related to operator’s skill. Digital control is the first step in the control of machine tool.Continue reading→
