The lubrication part of the precision cylindrical grinder adopts automatic lubrication, so it can save a certain amount of lubrication work. The CNC internal grinder has a sealed cover, so it can play a good protection role. CNC Internal Grinder should adjust the position of travel stop according to the grinding length of the workpiece. After adjustment, it should be tightened. The grinding wheel should be selected according to the material of the workpiece and the grinding amount. The CNC Internal Grinder should be checked before using the grinding wheel. If the grinding wheel has cracks, it can not be used. After the grinding wheel is installed, the static balance test shall be carried out, and then it shall be idled for 3 to 5 minutes.
A brief introduction to the structure of precision cylindrical grinder. The surface grinding method is often used for semi finishing and finishing of various surfaces with high surface quality requirements. The common machine tool for surface grinding is surface grinder. The working surface of grinding wheel can be circular surface or end face. It is convenient and reliable to use single motor for machining. Three motors are used to drive the grinding wheel, and the rotary motion of the grinding wheel is directly driven by the load type motor. The hydraulic pump is driven by the hydraulic pump motor and completes the reciprocating (longitudinal feed) movement of the worktable, the cross feed movement of the grinding wheel rack, the rapid lateral movement of the grinding wheel rack and the lubrication of the guide rail of the worktable. The motor driving the cooling pump provides coolant for grinding.
If the vibration of the precision cylindrical grinder is still not eliminated after the above actions, we should check the problems of grinding machine sanding and wheel fixing flange. The first is the grinding wheel. Due to the uneven quality of the grinding wheel on the market, there are generally two factors affecting the vibration of the grinding wheel. One is that the particle size of the grinding wheel is not uniform, and the center of gravity is unstable when it is rotated; the other is that the inner hole is not standard and large. For example, our grinder flange diameter requirement is 31.75, and if the grinding wheel is 32, it will jump up and down and cause vibration. When we buy grinding wheel, we must ask the specification clearly. It is suggested to buy the grinding wheel with good quality. The bad grinding wheel will affect the processing effect, and it is easy to crack and explode in the process of grinding. The poor balance effect of grinding wheel will seriously affect the life of grinding machine spindle
