Hongfu national standard drill sleeve has high precision, long inner hole guide and long durability
High precision and long life drill sleeve national standard drill sleeve
Hongfu drill sleeve has high precision and long inner hole guide to ensure the drilling position and hole accuracy. . And the price is lower, the quality is better, the life is longer and more wear-resistant.
A good drill bushing must meet the following conditions
The smaller the precision tolerance of the inner hole size, the better. It can suppress the swing head of the drill. The tolerance increases and the product error increases. Therefore, the size of the drill bushing must be of the highest grade to ensure the best quality. The required accuracy
The smoother the inner hole, the less friction it will cause, which can significantly improve the life of the drill bit. The hole cut by wire cutting may look bright, but because it is electrical discharge machining, small spark holes will be left on the surface, which is also the culprit of friction on the drill bit
br/> The concentricity of the inner hole and the outer hole is not high, and the machining accuracy is also low. The cumulative error will increase
The hardness of the drill bushing cannot be too hard or too soft. Some drill bushings are made of alloy with high hardness and long service life. But the damage to the drill bit is also great, just like an egg hitting a stone. The cost of cutting tools after a few months is astonishing. The life of the soft drill bushing is short and cannot guarantee long-term accuracy. It is ideal to keep the hardness of the drill bushing at about 10°C
