How to use the Drill Bit Grinder?

1. First, check the material of the drill bit, because it is used to select the appropriate grinding wheel(types of grinding wheel: CBN and SDC; CBN for HSS(High Speed Steel), SDC for Carbide), that to be assembled the drill bit grinder.

2. Second, checking the diameter of drill bit, and then to select the appropriate collet chuck. In general, the types of collet chuck as follow: ER20, ER25, and ER40, but the exact dimensions are subjected to the manufacturer’s standard.

3. Third, clamping after selecting collet chuck, and adjusting the measurement of grinding, then you should to press the power button to start the drill bit grinder, now observing the situation of the operation drill bit grinder.

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
