With a wheel of a method for cutting a workpiece

Grinding is the grinder as a cutting tool for machining a workpiece with a grinding wheel method. Characteristics of the method are: (1) Since the abrasive wheel itself has high hardness and heat resistance, and therefore the grinding can be processed high hardness materials such as hardened steel, cemented carbide.
2) determine the characteristics and grinding wheel grinding system can make even trace cutting, general ap = 0.001 ~ 0.005mm; high grinding speeds, generally up to v = 30 ~ 50m / s; grinder stiffness; using hydraulic transmission, thus grinding can be economically obtained with  grinding disc high precision (IT6 ~ IT5) and a small surface roughness (Ra = 0.8 ~ 0.2μm). Grinding is one of the main methods for finishing parts. (3) Due to intense friction, leaving the high grinding zone temperature. This causes stress and deformation of the workpiece, causing the surface burns. Therefore must inject a lot of grinding coolant to reduce the grinding temperature. Coolant can also play chip and lubrication. (4) a large radial force when grinding. This will cause the machine - elastic workpiece concession system, the actual depth of cut is less than the nominal depth of cut - wheel. Therefore grinding to be accomplished, the light should not enter the knife mill, to eliminate abrasive sanding belt  errors. (5) After the blunt abrasive grinding force also increased, resulting in grains or broken off, exposing sharp edge again, this feature is called "self-sharpening." Self-sharpening the grinding within a certain time can be normal, but beyond a certain time after the work should be carried out manually trimmed to avoid grinding force increases caused by vibration, noise and damage the quality of the workpiece surface structure and surface grinder grinding machine grinding motion Many species, mainly surface grinder, cylindrical grinder, the grinder, universal cylindrical grinding machine (also grind the hole), gear grinding, thread grinding machine, rail grinding, centerless grinder (grinding cylindrical) and tool grinder (grinding tool), etc. Here surface grinder and movement. 1 Surface grinding machine structure (with M7120A, for example, where: M - class machine grinder; 71 - horizontal axis moments desktop surface grinder; 20 - Working table width is 200mm; A - the first major improvements.)
1) wheel frame - install wheel and drive wheel for high-speed rotation, wheel frame dovetail slide along the rail  ceramic belt movement of lateral clearance of manual or hydraulic. (2) slide - install wheel frame and drive wheel frame rails along the column up and down movement. (3) Column - bearing slide and wheel frame. (4) Bench - installation piece by reciprocating linear motion of the hydraulic system drive for. (5) bed - supporting bench, install other components.
(6) Coolant system - providing coolant (saponification oil) to the grinding zone. (7) hydraulic system - consisting of: a dynamic element - as pumps, hydraulic system pressure oil supply; b actuators - for the cylinders, and other parts of the table driven movement; c control elements - .. various valves, pressure control, speed, direction, etc.;. d of the auxiliary element - such as fuel tanks, pressure gauges.
