Cylindrical grinding machine processing

The range of technology universal cylindrical grinder is wide, can grinding cylinder inside and outside, inside and outside the cone surface and face, etc. But lower production efficiency, suitable for single piece small batch production. General cylindrical grinder and universal cylindrical grinder on the structure of main difference is that: the general cylindrical grinder head frame and grinding wheel rack are not around its vertical axis adjustment Angle, spindle can't turn head, not in circular grinding tool. As a result, the range of technology general cylindrical grinder is narrow, can only grinding cylinder and taper smaller outside the cone surface. But as a result of its main parts structure level, less rigid, can use large grinding dosage, thus productivity is higher, at the same time easy to ensure the quality of grinding. Centerless external cylindrical grinding machine for grinding. Is not supported on the top or clamping workpiece in chuck, but was placed in between the wheel and the wheel directly, by plate and roller bearing, by grinding the cylindrical surface of the workpiece itself as locating datum. There are two kinds of centerless external cylindrical grinding machine grinding method: through plunge grinding method and grinding method. Grinding machine type and use abrasives ( Grinding wheel, abrasive belt, abrasive and abrasive materials, etc. ) As a tool for cutting machine, referred to as grinding machines. There are many kinds grinding machine. Mainly include: cylindrical grinder, internal grinder, surface grinder, tool grinder and a specialized grinding machine used for grinding specific surface and the workpiece, such as spline shaft grinding machine, the camshaft grinding machine, the crankshaft grinding machine, etc. The above are for the use of grinding wheel for cutting tool grinding machine. In addition, there are flexible abrasive belt as the abrasive belt grinding machine of cutting tool, with oil stone and abrasives for the fine grinding of cutting tool grinding machine, etc. Grinding machine can process all kinds of surface, such as internal and external cylindrical and conical surface, plane, involute tooth profile surface, helical surface and various forming on the surface. Grinding machine for waste processing, rough machining, finish machining and superfinishing, can undertake all kinds of high hard, superhard materials processing, can also grinding tool and cutting off, etc. , process very extensive. Second, grinding work movement ( A) Cylindrical grinding machine 1. Type M1432A universal cylindrical grinder M1432A universal cylindrical grinder is common grade precision cylindrical grinding machine. It is mainly used for grinding cylindrical, conical outer circle and inner hole, can also grinding of ladder shaft shoulder, flat end, etc. This machine has good versatility, but the production efficiency is low, so it is suitable for single piece small batch production. Centerless external cylindrical grinding centerless grinding, cylindrical grinding machine for workpiece placed between grinding wheel and the wheel, and the center is higher than the grinding wheel and workpiece and the roller center, by grinding cylindrical surface locating datum, bearing on the plate. Centerless external cylindrical grinding machine productivity is high and machining accuracy is good, but only for grinding cylindrical surface in a row, and grinding machine adjustment time consuming, only suitable for batch and mass production. ( 2) Internal grinder internal grinder for grinding all kinds of cylindrical hole ( Hole, blind hole, hole on the surface of the ladder hole and intermittent, etc. ) And cone hole, some internal grinder with grinding end face grinding head. Internal grinder main types are the common internal grinder, centerless grinder and planetary internal grinder. Regular internal grinder adopts longitudinal grinding and cutting grinding grinding inner hole. Adopt special end mill unit, in a clamping workpiece grinding inner hole and end face. In centerless grinding machine for processing cylindrical surface already finish machining thin-walled workpieces, such as bearing ring, etc. ( 3) Surface grinding machine surface grinding machine is mainly used for grinding various artifacts on the plane. According to different grinding methods and machine layout, surface grinding machine should have the following four types: horizontal spindle and rectangular table surface grinder, horizontal spindle surface grinding machine with rotary table, vertical rectangular table surface grinding machine and vertical shaft surface grinding machine with rotary table.
