Diamond internal grinding wheel

Internal grinding with diamond grinding wheel and cylindrical grinding is different, specifically, the following points: 1. The workpiece clamping within clamping workpieces on grinder commonly used three-jaw chuck, four-jaw chuck, Disk and plate like. The workpiece can be used for mass production of specialized design and manufacture of special jig fixture. 2. The inner circle inside the mill grinding characteristics compared with the cylindrical grinding diamond grinding wheel has the following characteristics: (1) wheel shaft length, poor rigidity, deformation, vibration, poor processing quality; (2) grinding bore high precision, roughness Ra0.8 ~ Ra0.4; small (3) diamond grinding wheel diameter, low speed, low grinding efficiency; (4) the small diameter diamond grinding wheel, abrasive cutting more often, wear faster; (5) Chip difficult, easy to plug the wheel; (6) Cutting temperature is high, the cooling conditions are poor; good (7) adaptability, can process hard materials, blind holes, stepped holes and so on. 3. The method of grinding the inner circle (1) vertical grinding method: Requires diamond wheel rigid extensions is better than grinding wheel width distance piece mouth 1/3 ~ 1/2, otherwise there will be processing error. (2) horizontal milling. (3) centerless grinding inner circle: for thin wall large round hole. (4) coordinates grinding. Inner circle grinding wheel materials can be divided into: corundum (A), white fused alumina (WA), chromium corundum (PA), single crystal corundum (SA), mixed corundum, SG. Binding agent: ceramics, resin. Line speed: 35m / s ~ 80m / s. Adaptation grinder: surface grinding, tool grinding, cylindrical grinding, thread grinding, gear grinding [molding, developed into], roll grinding, grinding force. Wheel size: Diameter φ30 ~ φ1200 thickness of 6 to 400. Corundum (A): suitable for lower hardness of carbon steel, alloy steel, malleable iron grinding. Corundum (WA): used for grinding the workpiece quenching hardness HRC60 or less, is widely used in surface grinding, tool grinding, cylindrical grinding, thread grinding, gear grinding and profile grinding several occasions. Chromium corundum (PA): complete replacement corundum, wheel shape retention, better than corundum grinding roughness under the same circumstances. Wheel size and roughness conservative value corresponding to 36 to 46 size: Ra1.6 54 ~ 60 size: Ra0.870 ~ 80 size: Ra0.4 90 ~ 100 size: Ra0.2 The company Norton wheel Stock Stock situation: OD φ200 following tools grinding wheels different specifications φ205 ~ φ450 outer diameter cylindrical grinding, surface grinding wheel, gear grinding wheel used different specifications outer diameter φ500 ~ φ1200 only specific users to do stock monocrystalline corundum (SA): for high hardness , strength, toughness, good grinding of metal. Such as tool steels, austenitic stainless steel, titanium, spray alloys. Green silicon carbide (GC) black silicon carbide (C): silicon carbide abrasive itself high hardness, brittleness, made after the self-sharpening wheel for grinding cast iron non-ferrous metal, carbide, copper, aluminum and the like. SG Abrasives: Norton SG abrasive is a Saint-Gobain company developed and patented abrasive with high hardness, good toughness, sharpness and strong features. Loss made after the grinding wheel, grinding wheel shape retention is good, because with column crystal structure completely, a small amount of trimming can be achieved by a good grinding effect. Widely used in high hardness, high strength, high toughness metal grinding. Semi-brittle corundum (57A): Semi-brittle corundum made using resin bonded grinding wheels, widely used in heavy grinding high-speed steel, such as cobalt, aluminum, high-speed steel bowl-shaped diamond wheel for use in freestyle tool grinder much more common installations. in universal tool grinder, carbide cutting tools for various grinding, is a broader application of diamond grinding wheel, while in the other use of the grinding process, for the particularity of shape, less use in surface grinding When cylindrical grinding, internal grinding and other conventional grinding, diamond grinding wheel This basically useless. Therefore, this type of wheel specifications using more concentrated in the outer diameter of 100,125,150 of these types, but the hole is mainly based on machine requirements, thickness and angle depends on the requirements of the workpiece to be machined diamond wheel, of course, the emphasis is on the wheel use efficiency and wear resistance, diamond percentage weight is very important. Therefore, the concentration is bowl-shaped Diamond Wheel diamond place more value internal grinding Grinding Wheel House Lee, Abrasives Co., Ltd.
