Select power head type according to different conditions, we should pay attention to the following:
1, the size of the drill hole, determines the diameter of the power head drill.
2, how much the depth of drill hole, it is a blind hole or a through hole.
3, what is the material of processing work piece? Because different material’s hardness is different, the required power head is also different.
4, use pneumatic or hydraulic drive? Because both have a greater difference.
5, what is installation way? Horizontal type, vertical type, backstroke type or inclined type.
6, how much is the requirement of rotational speed (cutting speed)?
7, how much is the required motor power in normal work?
8, what is kind of belt form? Triangular belt, synchronous belt or chain?
9, what is king of chuck form? Such as ER model, AS model, JT model, MT model, NT model and so on.
Different power head effect is different, the range of application are also different. Such as hydraulic driven power head, is suitable for processing large hole, feeding intensity big, hard material work piece, but the heavier in weight. And pneumatic driven power head, is suitable for processing small hole, feeding intensity small, back speed high, light weight work piece, use very convenient, but can’t processing more hard material.
