Description
Technical field
The utility model relates to field of machining technology, more particularly, to a kind of grinding cutterhead.
Background technique
With the development of economy, the grinding and polishing processing capacity of the progress of technology, various planes is continuously increased, in order to improve life
Efficiency is produced, people constantly design the bigger polisher lapper of abrasive disk, to be once capable of processing more workpiece.But increase is ground
Grinding wheel diameter will increase the difficulty of processing of abrasive disk, increase grinder manufacturing cost.Simultaneously as big abrasive disk inside and outside half
Diameter gap is larger, and linear velocity has very big difference, and therefore, the grinding quality of workpiece is also affected.
Current milling cutter be usually include cutterhead body and positioned at the grinding part of cutterhead body one end, utilize driving dress
It sets and milling cutter rotation is driven by shaft, workpiece surface is ground by grinding part.But current milling cutter according to
So have the following problems:
Grind section can generate big calorimetric in attrition process due to the cyclic structure using monoblock type due to frictional force
Amount, impacts grind section, also, the grindstone dust that grind section can not generate workpiece in process of lapping is effectively discharged,
To make the workpiece surface out-of-flatness after grinding or exist to scratch, grind section service life can also be impacted, in order to keep away
Exempt from this phenomenon occur, generally requires to take a significant amount of time to grindstone dust removal, so that the production time is largely wasted, also,
Therefore to the regular replacement of abrasive disk but also the production cost increases.
Based on this, the utility model provides a kind of grinding cutterhead to solve above-mentioned technical problem.
