Abstract
Include grinding wheel, polishing cotton the utility model is related to a kind of grinding wheel structure reducing bore surface roughness, the latter half of the grinding wheel is provided with 3~4 circumferential recess, and groove width 4mm, deep 4mm, the inside grooves, which are installed, polishes cotton.The grinding wheel structure of the utility model can realize that 0.2~0.4 part processing request of endoporus roughness Ra, processing efficiency improve 50% or more.
Description
Technical field
The utility model is related to a kind of grinding wheel structures reducing bore surface roughness.
Background technology
In aviation field, bore required precision is higher, and roughness, which generally requires, reaches Ra0.2~0.4.Using general
In logical when grinding abrasive disk processing, since machine spindle rotating accuracy and diamond truer precision limit, piece surface light after grinding
Spend bad, low precision, roughness can only achieve Ra0.6 or more.Therefore, it in order to improve inner bore surface roughness, need to use high-precision
Degree digital control internal grinder is processed, and considerably increases production cost in this way.The numerically control grinder amount of feeding is small simultaneously, crushing number
More, product processing efficiency is relatively low.
Invention content
The purpose of this utility model is to provide a kind of grinding wheel structure reducing bore surface roughness, is ensureing product
While processing efficiency and cost, bore roughness precision is improved, Ra0.2~0.4 is reached.
The specific technical solution of the utility model is that the grinding wheel structure of the reduction bore surface roughness includes
Grinding wheel, polishing cotton, the latter half of the grinding wheel are provided with 3~4 circumferential recess, groove width 4mm, deep 4mm, the groove
Inside installation polishing cotton.
The utility model is arranged fluted on grinding wheel, and since depth of groove is shallow, length is short, do not influence grinding wheel intensity and
Security performance, inside grooves installation polishing cotton, grinding wheel is when being ground inner bore of part, using grinding wheel front end inner hole grinding, after use
End face polishes cotton and completes to polish to endoporus, to realize the purpose for improving polishing surface roughness.The utility model improves endoporus mill
It is ideal to cut surface roughness precision effect, realizes the inner hole structure for processing higher roughness requirements on plain grinding machine internal,
Production cost is reduced, while improving product processing efficiency.The grinding wheel structure of the utility model can realize that endoporus is coarse
The part processing requests of Ra0.2~0.4 are spent, processing efficiency improves 50% or more.
Description of the drawings
Fig. 1 the utility model structure diagrams.
Specific implementation mode
As shown, the grinding wheel structure for reducing bore surface roughness includes grinding wheel 1, polishing cotton 2, the grinding wheel
1 latter half is provided with 3~4 circumferential recess, and groove width 4mm, deep 4mm, the inside grooves, which are installed, polishes cotton 2.
