A grinding machine is mainly used to rotate a grinding wheel to grind workpieces to achieve the required flatness. According to the shape of the worktable, it can be divided into two types: rectangular worktable and circular worktable. The main parameters of a rectangular worktable curved grinding machine are the width and length of the worktable, while the main parameters of a circular worktable curved grinding machine are the diameter of the worktable surface. According to the different types of shafts, they can be classified into horizontal shaft and vertical shaft grinding machines. Such as the M7432 vertical shaft circular table curve grinding machine and the M7130 horizontal shaft rectangular table curve grinding machine.
Operating Instructions for Curve Grinding Machines
1. Positioning of curve grinding machines
The machine tool should reserve an additional 300mm or more outside the movement space. Each anchor screw should be tightened, and the level of the worktable front and back as well as left and right should be within 0.04/1000mm. The requirements for installing frequency converters need to be higher.
Inspect every three months, adjust the level of the workbench surface, and tighten each anchor screw.
2. Grinding wheels for curve grinding machines
The selected grinding wheel must be capable of withstanding a turnover speed of more than 2000m/min.
The use of damaged grinding wheels is prohibited.
The flange of the new grinding wheel must be balanced when it is installed.
The feed stroke for grinding machines under 800mm is 0.03mm, and for those over 800mm, it is 0.05mm
3. Spindle of curve grinding machine
Before installing the grinding wheel, it is necessary to ensure that the main shaft rotates clockwise.
When starting up, the main shaft must be turned on first and then the water flushing.
4. Hydraulic device of curve grinding machine
The curve grinding machine uses hydraulic oil with a viscosity of 46.
The hydraulic oil of the new machine needs to be replaced after three months of use, and then once a year thereafter. At the same time, the oil tank must be cleaned.
Check the hydraulic oil level every day. The oil level should be maintained between the low and high marks.
Before starting the hydraulic motor, it is necessary to ensure that the flow speed control rod (if equipped) is in the closed position.
The magnetic attraction must be turned on first and then the hydraulic system
5. Lubrication device for curve grinding machine
The lubricating oil used should be guide rail lubricating oil with a viscosity of 32 to 46.
Check the fuel level in the tank (pool) every day to ensure it is above the lower limit.
Check whether the oil passage of the guide rail is unobstructed every week to prevent the guide rail from losing oil.
It is recommended to clean the fuel tank every three months.
Grease should be added regularly as stipulated.
