The types of process characteristics and grinding machine

Using abrasive or non-metallic abrasive ( Such as grinding wheel, abrasive belt, abrasive and abrasive, etc. ) Processing machine tool called workpiece surface grinding machine, it is in order to adapt to the workpiece in precision machining and a machine tool, is a kind of precision machine tools. Usually mainly abrasive rotating movement, the movement of the workpiece rotate and move or abrasive for feed movement. Usually called the use of grinding wheel processing machine tool grinding machine, such as cylindrical grinder, surface grinder, and use the oil stone, abrasive materials as a cutting tool machine tool called 'fine grinding machine tool'. The process features of grinding machine ( 1) Cutting tool is made up of countless small, hard and sharp non-metallic abrasive binder of edge tools, and be master of high-speed rotating movement. ( 2) Versatility is strong, wide adaptability. It can be other common machine tool can not machining materials and parts, especially suitable for processing high quenching hardness steel or other high hardness materials. ( 3) Grinding machine type, range. Due to the development of high speed grinding and heavy grinding, grinding machine has been extended to the rough machining and manufacturing precision blank parts, many parts can need not directly through other processing by grinding machine processed into finished products. ( 4) Small grinding machining allowance, high production efficiency, are easier to implement automatic and semi-automatic, can be widely used in assembly line and automatic line processing. ( 5) High grinding accuracy, good surface quality, but the ordinary precision grinding, also can undertake precision grinding and high precision grinding processing. Many different kinds of the type of grinding machine grinding machine, and adopt different methods to process according to the use, can be roughly divided into the following categories. ( 1) Cylindrical grinding machine mainly grinding rotary surfaces, including universal cylindrical grinding, cylindrical grinding machine and centerless grinding machine, etc. Cylindrical grinding machine is divided into general cylindrical grinder and universal cylindrical grinder, in ordinary cylindrical grinding machine can grinding on the workpiece outer cylinder and the outer conical surface, on the universal cylindrical grinder can also grinding cylinder and cone surface and face, the main parameters of the cylindrical grinding machine for grinding largest diameter. ( 2) Internal grinding machine mainly includes internal grinder, centerless grinder and planetary internal grinder, etc. ( 3) Surface grinding machine for grinding various plane, including horizontal spindle and rectangular table surface grinder, vertical rectangular table surface grinder, horizontal spindle surface grinding machine with rotary table and vertical spindle surface grinding machine with rotary table, etc. Worktable can be divided into rectangular table and circular table two, main parameters of the rectangular table surface grinder for workbench mesa width, the main parameters of surface grinding machine with rotary table for workbench mesa diameter. ( 4) Tool grinding machine. For grinding various tools, such as template or card board, including curve grinding machine, drilling groove ( Spiral groove) Grinding machine, grinding machine and tap card board groove grinding machine, etc. ( 5) Cutting tool, cutting tool grinding machine. Used for grinding various cutting tools, including universal tool grinder ( Can grinding all kinds of commonly used tool) , pull the blade grinder and hob sharpening machine, etc. ( 6) Specialized grinder. Specially for the grinding of parts on a surface, including the crankshaft grinding machine, the camshaft grinding machine, grinding machine, piston ring of spline shaft grinding machine, the ball bearing ring groove grinding machine and the roller bearing ring raceway grinder, etc. ( 7) Grinding machine. For abrasive cutting tool, used for finishing was carried out on the workpiece processing, in order to obtain high accuracy and small surface roughness. ( 8) Other grinding machine. Including honing machine, polishing machine, superfinishing machine, grinder, etc.
