Abstract: Automatic taper shank drill tapping machine use the matters needing attention, common drill chuck is with taper shank, linking to the main shaft driven by touch the friction cone bit rotation, the taper shank and the taper sleeve surface roughness and shape accuracy demand is very high.
Automatic taper shank drill tapping machine use the matters needing attention of taper shank, usually with taper shank drill chuck is connected to the main shaft, driven by cone contact the friction of the drill bit rotate, and the taper shank and the taper sleeve surface roughness and form accuracy is very high, if the taper shank and the taper sleeve surface abrasion, oil and foreign matter, contact area and reduces friction cone, easy to fall off, serious will complete failure.
Another cone connected mainly bear axial and rotational torque, if low precision drilling machine or swing amplitude is larger when the drill hole, can lead to taper off, especially when drilling to drill wear quickly, because a bit uneven stress, easily stuck or lead to taper shank fall off. So the solution to this problem has the following several aspects:
1, check the surface of the taper shank and the taper sleeve, there can be no wear, burrs, grease, foreign body.
2, installation and removing drill taper shank, cannot use the hammer banged on, to use a special tool.
3, ensure the accuracy of the drilling machine.
4, Do not exceed the scope of the use of a drilling machine, if more than the maximum limit using a large drill bit diameter, etc.
5, when drilling machine drilling should be workpiece clamping. Artifacts wobble a bit off or break easily, also easy to cause accidents.
6, Driller quick drills wear, the strength should be soft, slow feed, prevent death.
