Manufacture And Design of Cemented Carbide Guide Sleeves

Any deep hole drilling machine must have a guide device, so whether it is a deep hole or a shallow hole, the deep hole drill must have a guide device. And now the best material guide sleeve on the market is the cemented carbide guide sleeve.

The quality of the carbide guide sleeve depends on the processing quality, affecting the durability of the tool, affecting the dimensional accuracy of the hole to be machined, and affecting the surface roughness, straightness, especially the size of the entrance, too large a gap, will cause the vibrating tool, reduce the tool life, if the swing is too large, serious time will be in the beginning of the feed, immediately destroy the blade. Second, the size is too large to affect the formation of the aperture size, so the cemented carbide guide sleeve and drill diameter must have a reasonable choice, and the shape of the guide sleeve is best used in some cases. 

At present, our domestic deep hole drilling guide sleeve is basically fixed, so the best situation in the guide sleeve diameter is greater than five thousandths of the drill diameter, which is the most ideal, the maximum is not more than 2 wires, of course, in the design. Because the drill pipe is long, several support frames, the drill pipe plus the support frame can not be like a straight line, and there are some unavoidable vibrations in the cutting, if more than 2 wires, it needs to be replaced. If not replaced, the longer it will affect the processing quality.

This is in batch production, mass production, to have carbide guide sleeve. If there is no guide device at the beginning, it is impossible to cut, so whether the guide sleeve is designed reasonably or not plays an important role.
