Operating instructions and precautions for surface grinder

a kind of grinder The grinding wheel is mainly used to rotate and grind the workpiece to achieve the required flatness. According to the shape of the worktable, it can be divided into rectangular worktable and circular worktable. The main parameters of the rectangular worktable surface grinder are the width and length of the worktable, and the main parameters of the circular worktable surface grinder are the diameter of the worktable. According to different shaft types, it can be divided into horizontal shaft and vertical shaft grinder For example, M can control the quality of products. 7432 vertical axis round table surface grinder, M7130 horizontal axis rectangular table surface grinder

operating instructions for surface grinder

1: positioning of surface grinder

the machine tool should reserve more than 300mm outside the maximum movement space, each foot screw should be tight, and the front, back, left and right levels of the table should be within 0.04/1000mm. (the requirements for installing frequency converter need to be higher)

check every three months, adjust the level of the workbench, and tighten each foot screw

2: grinding wheel of surface grinder

the selected grinding wheel must be able to withstand a cycle speed of more than 2000m/min

it is forbidden to use broken grinding wheels

the flange of the new grinding wheel must be balanced

before formal grinding, the grinding wheel needs to idle for 5 minutes

maximum feed to avoid machine failure and personal injury. 0.03mm for grinding machines with a stroke of less than 800mm and 0.05mm for grinding machines with a stroke of more than 800mm

3: the spindle of surface grinding machines

before installing the grinding wheel, make sure that the spindle rotates clockwise

when starting the machine, the main shaft must be turned on before flushing

4: surface grinder hydraulic device

surface grinder uses hydraulic oil with viscosity of 46

the hydraulic oil of the new machine needs to be replaced after three months of use, and then once a year. At the same time, the oil tank must be cleaned

check the hydraulic oil level every day, and ensure that the oil level is between the lowest and highest line

before starting the hydraulic motor, make sure that the flow speed regulating lever is in the closed position

magnetic absorption must be turned on first and then hydraulic pressure

5: the lubricating oil of surface grinder

uses guide rail lubricating oil with viscosity of 32 and measurement value more accurate. (meiweida No. 1 or 1405 is recommended)

confirm the oil volume of the oil tank (pool) every day to ensure that it is above the offline level

check whether the oil circuit of the guide rail is smooth every week to prevent oil loss of the guide rail

it is recommended to clean the oil tank every three months

grease shall be filled regularly as required

6: the left and right mechanism of the surface grinder

it is forbidden to adjust the left and right travel when the workbench is moving

when the steel cable of the workbench is loose, it should be adjusted immediately. (this article applies to manual models)

7: the flushing and dust suction device of the surface grinder

the filtering of the dust suction box must be cleaned every two weeks

the cold water tank must be cleaned once a month

it is forbidden to use empty * to clean the surface grinder
