Description

Numerical control grinding for horizontal honing polishes compatible device

Technical field

It the utility model is related to a kind of numerical control grinding for horizontal honing and polish compatible device, grind, polish same honing （Deep hole machining）Equally, precision optical machinery manufacture field is belonged to.

Background technology

Traditional honing is workpiece car, after boring, and workpiece accuracy is improved with Honing process, and effect is relatively low, existing honing be The heavy honing developed on the basis of original honing.

In last century the eighties, due to the pulling out of steel pipe, roll technology and improve, its refined pipe is no longer through car, borer sequence, directly With Honing process into finished product, so as to promote honing technique（Honing machine manufactures and grinding tool used-emery stick manufacturing technology）Development, So that Barrel of Hydraulic Cylinders and cylinder barrel, almost all be spermaduct with Honing process come performance level.Sand used in heavy honing Bar is unlike material and varigrained abrasive material makees bonding agent with metal or ceramics or epoxy resin, after formed at normal temp, through high temperature Roasting forms, therefore emery stick has higher-strength and hardness, and it can be subjected to forced feed, and here it is heavy honing.Due to the sand Bar has hard, crisp characteristic, and it grinds speed can only be in 0.5-1 meter per second scopes.It is if fast again.Its workpiece will be scratched, and be roughly ground in honing When, because forced feed and abrasive grain are larger, its work efficiency is higher.But rough surface, must be through half fine grinding, fine grinding, due to abrasive material Granularity attenuates, and its its work efficiency also declines therewith, and the workpiece accuracy through honing is up at present。

It is to improve mill speed to improve work efficiency and the maximally effective technological measure of precision, and this is exactly honing shortcoming part, this Limitation is that honing itself can not overcome.

In recent years to overcome honing limitation, there is boring, rolling technology, the process efficient and Product Precision also reaches, but because its equipment is expensive and requires very high-precision blank, more expensive boring and roll extrusion head in addition, can only single size, a pair One boring and rolling, it is impossible to which general, this technique is carried out also being limited to.

Heavy honing technique is still largely using, and under current background, how to improve existing honing machine function, overcomes its office Sex-limited is needed for situation, and it is also the certainty of technology development.
