Description

A kind of grinding rubber for preventing secondary scuffing technology based on absorption

Technical field

The utility model relates to milling tool technical field, specially a kind of grinding that secondary scuffing technology is prevented based on absorption Rubber.

Background technique

Grinding passes through lap tool and workpiece under a certain pressure opposite using applying or be press-fitted the abrasive grain on lap tool Move the finished machined (such as machining) carried out to finished surface.Grinding can be used for processing various metals and nonmetallic materials, The surface shape of processing has plane, inside and outside cylindrical surface and circular conical surface, convex, concave spherical surface, screw thread, the flank of tooth and its alloytype face.Processing essence It spends up to IT5~IT01, surface roughness is up to Ra0.63~0.01 micron.

Grinding method generally can be divided into it is wet grind, dry grind grinds 3 classes with half-dried.1. wet grind: liquid is ground in also known as stuccoing grinding Agent continuously fills or coated in lapped face, and abrasive material is constantly slided and rolled between workpiece and lap tool, forms cutting movement.It is wet to grind It is generally used for rough lapping, micron power granularity used is coarser than W7.2. dry grind: also known as embedding sand grinding is uniformly being press-fitted abrasive material In lap tool superficial layer, when grinding, need only be coated with the auxiliary materials such as a small amount of stearic acid mixing rouge on lap tool surface.Dry grind is usually used in Smooth grinding, micron power granularity used are narrower than W7.3. half-dried grind: being ground similar to wet, grinding agent used is paste abrasive pastes.Grinding was both Manual operations can be used, can also be carried out on grinder.Workpiece first must obtain higher pre-add with other processing methods before the milling Work precision, stayed grind are generally 5~30 microns.

Lap tool is the tool for making workpiece abrasive forming, while being the carrier of grinding agent again, and hardness should be lower than the hardness of workpiece, There is certain wearability again, common gray cast iron is made.The metallographic structure of wet lap tool is based on ferrite；Dry lap tool is then with equal Even tiny pearlite is matrix.When grinding M5 screw thread below and complex-shaped miniature workpiece, mild steel lap tool is commonly used.Grinding When aperture and softer metals, brass, red copper lap tool are mostly used greatly.Lap tool should have enough rigidity, working surface to have compared with High geometric accuracy.Lap tool is also cut and is worn during the grinding process, such as suitable operation, its precision can also be mentioned Height enables the machining accuracy of workpiece to be higher than the original precision of lap tool.

Grinding technics is widely applied because of that can obtain higher surface roughness, especially mobile phone shell processing and Furniture processing etc., has the basis that has a wide range of applications, currently, commonly used coated abrasive tool can be divided into two greatly with substrate classification at present The advantages of class: first is that paper base material: it is that coated various hard abrasive materials form on paper base, such product is: cheap, be easy to Production is most traditional production technology；The disadvantage is that: easily tear rotten, pulling force is not good enough, heat dissipation is slow, workpiece to be machined grinding stress not Uniformly, Precision Machining is undesirable；Second is that cloth base material: it is that coated various hard abrasive materials form on cloth base, class product it is basic Performance and paper product are close, and advantage is: stretching resistance is big, indeformable, grinding force ratio paper base class product more by force；Both grind Mill mode has that the abrasive dust that the abrasive material that bruting process is fallen and workpiece are ground causes secondary scuffing to grinding workpieces face, It causes workpiece surface roughness to decline, influences quality of polishing.
