Automatic drilling machine attacks the use note of handle of tooth machine awl, normally getting collet is the handle that use drill and main shaft connective, the attrition force of surface contact relying on awl drives broach to rotate, and it is very tall that awl handle and awl cover exterior surface roughness and appearance precision demand, if awl handle and awl cover the surface to wear away, have smeary, discrepant content, the osculatory area of cone and attrition force can be reduced, fall off easily, serious can complete invalidation. Additional, cone join basically bears axial and torque coming back, if drilling machine precision is inferior or the left and right sides when broach bore shakes amplitude spends older saying, also can bring about awl handle to fall off, especially bore arrives to be gotten quickly when wearing, because broach gets power inhomogenous, easy card dies or bring about awl handle to fall off. Solve this problem to have the following sides so: 1, the surface that often checks awl handle and awl to cover, cannot have wear away, burr, smeary, eyewinker. 2, install and disassemble when drill awl handle, cannot beat with hammer vigorously, want to use special tool. 3, the precision that assures drilling machine. 4, the scope of application that does not exceed drilling machine, the old bit that if use,exceeds diameter of the biggest limitation. 5, answer when drill bore workpiece clamp. It is easy that workpiece swings make broach falls off or break off, cause safe accident easily still. 6, get workpiece fast when wearing, want gentleness forcibly, slow feed, prevent to get stuck dead.
