The method that abrade nicety machines

1 ～ 0.

008 μ M. 1.

Abrade and phyletic: ① is wet grind fluid shape abrasive Tu Fu or add continuously note have the face at grinding, make abrasive (workpiece of W14 ～ W5) and grind slide ceaselessly with scroll, realize pair of workpiece cutting thereby. Wet grind application is more. ② doing grinds abrasive (W3.

5 ～ W0.

5) is pressed equably embed grind provide surface layer to go up, abrade when need to grind an exterior besmear with a few lubricant. Dry grind multi-purpose grind at essence of life. ③ works partly grind place is with abrasive mushy and abrade cream, thick, essence grinds to all can be used. 2.

Abrade principle: ① imperceptible sex: Can undertake to workpiece 0.

01 ～ 0.

Cutting of 1 μ M. ② random sex: Workpiece and grind a random contact, nod mutual nap high, the error is reduced stage by stage, precision gets rising at the same time. ③ specific aim: Can detect workpiece, specific aim changes abrade position masters abrade time, assure size shape precision. 3.

Grind a material abrasive: 1) grinds a material is cast-iron: Abrade temper by dipping in water is hard not hard steel of temper by dipping in water reach cast-iron. Brass: Abrade all sorts of soft metals. 2) abrasive: ① abrasive: Cerium of alumina, carborundum, ferric oxide, oxidation. ② abrade fluid: Oil of engine oil, kerosene, animal and oleic acid, tristearin is acerbity. 4.

Abrade method: Abrade plane explains: After essence of life is ground, abrade plane undertakes commonly. When manual and abrade plane, abrasive Tu Yan grinds flat (grind) on, hold workpiece makes linear reciprocate or " 8 " the glyph moves. After abrade and proper time, workpiece transfer 180 ° of 90 ° ～ , in case workpiece tilts. Go up to workpiece local wait for grind facet, square aperture, narrow seam wait for the surface, also can hold grind undertake abrade. Batch is bigger the plane on simple spare parts on muller of Yi Keping face abrade. 5.

Abrade craft characteristic reachs application: ① equipment is simple, precision demand is not high. ② treatment quality is reliable. Can obtain very very low Ra is worth high accuracy. But cannot improve treatment commonly between face and other surface positional precision. ③ can machine aluminium of hard steel of all sorts of steel, temper by dipping in water, cast-iron, copper to reach its alloy, hard alloy, pottery and porcelain, glass and certain and plastic products. ④ is abrade and extensive use at sheet pre production machines all sorts of high accuracy face, can use at large quantities of mass-produced.
