Abstract
The grinding tool with semi-fixed abrasive grain mixture in different hardnesses has abrasive grains adhered in semi-fixing mode and comprises abrasive grains of at least two hardness levels in 70-94 wt%, and binding agent in 6-30 wt%. The present invention can realize precise processing in high efficiency.
Description
Technical field
The present invention relates to the accurate ultra manufacture field, especially a kind of semi-fixation abrasive grain grinding tool.
Background technology
Abrasive particle processing is the main means of present accurate ultra processing.Abrasive particle processing can roughly be divided into free abrasive processing (comprise and grinding and polishing) and fixation abrasive grain processing (as superfine grinding) two classes again.Fixation abrasive grain processing has the advantages that high material is removed efficient, its machining accuracy is approached free abrasive processing day by day, but require to use high high accuracy, the high rigid device of price, and, had a strong impact on the serviceability and the life-span of product because the affected layer that forced feed causes is darker.So accurate ultra processing at present still is processed as main flow with free abrasive.Free abrasive processing is not high to equipment precision requirement, and the machining accuracy height, affected layer is shallow even do not have.But it is low that the free abrasive rapidoprint is removed speed, and crudy and uniformity are very responsive to the cleanliness factor of processing environment, in case the hard bulky grain is invaded machining area, promptly produce dark cut on the machined material surface, cause rework rate and percent defective to increase, limited the raising of working (machining) efficiency.
Summary of the invention
Can't take into account the deficiency of machining accuracy and working (machining) efficiency in order to overcome existing abrasive particle processing method; the invention provides a kind of higher working (machining) efficiency that when guaranteeing high manufacturing accuracy, obtains, realize the semi-fixation abrasive grain grinding tool of the soft/hard abrasive grain mixing of accurate ultra processing efficiently.
The technical solution adopted for the present invention to solve the technical problems is:
The semi-fixation abrasive grain grinding tool that a kind of soft/hard abrasive grain mixes; bond in half set mode between the abrasive particle in the described grinding tool; the mass percent of each component in the described grinding tool is: abrasive particle 70%～94%; bond 6%～30%, abrasive particle wherein is made up of the abrasive particle of two kinds of different hardness at least.
As preferred a kind of scheme: the particle size range of described abrasive particle is 0.01～30 micron.
As preferred another kind of scheme: described abrasive particle is made up of the abrasive particle of two hardness leveles, and the part by weight scope of two kinds of abrasive particles is 9: 1～1: 9.
Further, described abrasive particle is made up of the abrasive particle of three hardness leveles.Certainly, also can form by four kinds, five kinds or more kinds of abrasive particle.
Described abrasive particle comprises hard abrasive and soft abrasive, and it is one of following that described hard abrasive can be: 1. aluminium oxide, 2. diamond, 3. corundum, 4. diamond dust, 5. garnet, 6. carborundum, 7. boron carbide.
It is one of following that described soft abrasive can be: 1. iron oxide, 2. chromium oxide, 3. cerium oxide, 4. zirconia, 5. titanium oxide, 6. silica, 7. magnesia.
Described bond comprises adhesive and additive, and wherein the mass percent of the whole grinding tool of each ingredients constitute is: adhesive 1%～15%, additive 5%～15%.
Described adhesive can be following one or more mixing: 1. starch based adhesive, 2. natural plant gum class adhesive, 3. natural polymer subclass adhesive, 4. cellulose family adhesive, 5. semisynthetic class adhesive, 6. synthetic class adhesive, 7. resinae adhesive.
Described additive can be following one or more mixing: 1. waterproofing agent, 2. filler, 3. defoamer.
Technical conceive of the present invention is: in the semi-fixation abrasive grain grinding tool of being made up of abrasive particle, adhesive and additive etc., abrasive particle bonds together by the mode of bond with half set, and adhesion strength is between free and set.In the semi-fixing abrasive grain process, higher bonding strength and good self-sharpening make semi-fixation abrasive grain grinding tool can keep higher material to remove ability for a long time.Again because semi-fixation abrasive grain grinding tool " trap " effect that the hard bulky grain is had---the hard bulky grain of invading machining area is absorbed in grinding tool top layer and institute, and to share load identical with abrasive particle, can effectively alleviate even eliminate the damage that the hard bulky grain causes workpiece, crudy and uniformity have been guaranteed, reduce rework rate and percent defective, thereby when guaranteeing high manufacturing accuracy, obtain higher working (machining) efficiency.
Because abrasive particle is in half set state in the grinding tool, so free relatively grinding of grinding tool rotating speed be greatly improved, and the semi-fixation abrasive grain grinding tool rotating speed of diameter 300mm is the highest can to reach 350rpm, and material is removed efficient and significantly improved.Owing to be in the abrasive particle of half set state the hard bulky grain is had " trap " effect simultaneously, can effectively prevent the surface damage that bulky grain produces, help the acquisition of high manufacturing accuracy.
The semi-fixation abrasive grain grinding tool that soft/hard abrasive grain mixes is made up of abrasive particle, adhesive and additive etc.Abrasive particle comprises a plurality of kinds, generally is the abrasive particle of two kinds of different hardness grades.Hard abrasive is the main abrasive action that rises in process, removes machined material fast; Soft abrasive is the main polishing action that rises in process, and defectives such as the crackle that hard abrasive is produced, cut are repaired, and improve machining accuracy.Mutually combining of soft/hard abrasive grain helps further to improve the precision and the efficient of semi-fixing abrasive grain processing.
Described soft/hard abrasive grain mix semi-fixation abrasive grain grinding tool in abrasive particle between bond in half set mode, the mass percent of each component in the described grinding tool is: abrasive particle 70%～94%, bond 6%～30%.Abrasive particle wherein is made up of the abrasive particle of two hardness leveles at least.It is one of following that described hard abrasive can be: 1. aluminium oxide, 2. diamond, 3. corundum, 4. diamond dust, 5. garnet, 6. carborundum, 7. boron carbide.It is one of following that described soft abrasive can be: 1. iron oxide, 2. chromium oxide, 3. cerium oxide, 4. zirconia, 5. titanium oxide, 6. silica, 7. magnesia.The particle diameter of employed abrasive particle approximately is that 30 μ m are following, and suitable particle size range is 0.01～30 μ m.Additive plays waterproof, froth breaking effect.
The manufacture process of the semi-fixation abrasive grain grinding tool that soft/hard abrasive grain mixes comprises steps such as batching, stirring, cast, froth breaking, baking and curing, the demoulding.
Beneficial effect of the present invention is: obtain higher working (machining) efficiency when 1, guaranteeing high manufacturing accuracy, realize accurate ultra processing efficiently; 2, in guaranteeing grinding tool, under the condition of abrasive particle half set feature, further improve working (machining) efficiency and surface quality.
