With high precision and high hardness increase in the number of mechanical parts, as well as the development of precision casting and precision forging process of rail grinding, grinding performance, varieties and production are constantly improving and growing. (1) Cylindrical Grinder: Grinding is mainly used for cylindrical and conical outer surface. (2) Internal Grinder: mainly used for grinding machine grinding of cylindrical and conical inner surface. In addition, there are both internal and external circular grinding grinder. (3) Coordinate grinder: internal grinder with precision coordinate positioning device. (4) Grinder: mainly used for clamping workpieces using mood, generally supported between the guide pulley and bracket rotation of the workpiece by the guide wheel drive, is mainly used for grinding cylindrical surface grinding machines. For example, the shaft support bearing and so on. (5) Surface Grinder: mainly used Grinding workpiece plane. a. cranked grinder for small size and high accuracy of the workpiece, grinding, machine including arc, plane, tank and other various shaped workpieces. b. Shuimo suitable for processing large workpiece machining high precision optical grinder, hand-cranked grinder with phase difference. (6) Belt Grinder: fast moving belt is mainly used for grinding the grinder. (7) grinding machine: mainly used for grinding the workpiece surface within a cylindrical outer surface grinder or. (8) Multi Grinder: mainly used for grinding cylindrical, conical inner and outer surface or plane, and can be used with a variety of moving equipment and accessories grinder grinding workpiece. (9) special grinder: mainly engaged in certain parts of the special grinding machine. Their processing objects can be divided into: spline shaft grinders, crankshaft grinding machines, cam grinding machines, gear grinding, thread grinding machines, grinders and other curves.

Operating Precautions a surface grinder, surface grinder positioning: maximal exercise machine outside the space should be reserved for more than 300mm, each foot screws tight around the table and around the level within 0.04 / 1000mm. (Installation requests are subject to higher inverter); prosecution every three months, adjusting the level of the work surface, each foot screws tight. 2, flat grinding wheel: selected wheel must be able to withstand weeks of speed 2000m / min or more; prohibition of the use of the wheel is damaged; new wheel mounted on the flange must be balanced; conducted before the official 7130 surface grinder grinding wheel need to idle 5 minutes ; maximum stroke of 800mm below the amount of feed grinder is 0.03mm, 800mm grinder for more than 0.05mm. 3, surface grinder spindle: Before installing the wheel must determine spindle clockwise rotation; boot, must first open the spindle open after flushing. 4, surface grinder hydraulic devices: surface grinder using a viscosity of 46 hydraulic oil; new machines need to be replaced after use hydraulic oil for three months after it replaced once a year, is also required to clean the tank; hydraulic oil level every day to check the oil level should ensure that the line between the lowest and highest; front hydraulic motor starts, shall determine the flow speed control lever in the closed position; must first start after opening the hydraulic magnetic suction 5, surface grinder lubrication devices: the use of lubricants viscosity lubricating rails 32 oil. (Recommended US Vectra 1 or No. 1405); confirm the fuel tank (pool) of oil a day, to ensure that more than offline; weekly check the oil is smooth rails, to prevent loss of oil rails; tank cleaned once every three months; lubrication regularly filling grease required. 6, surface grinder about agency: Do not adjust the stroke around the table at the time of movement; when the table is loose cables should be adjusted immediately. (This section applies to manual models) 7, surface grinder flushing and cleaning devices: vacuum tank filter must be cleaned once every two weeks; the cold water tank should be cleaned once per month; prohibit the use of air-cleaning surface grinder.
