Summary of Key Technical Points of Surface Grinders

In the field of modern mechanical processing, the surface grinder is a crucial piece of equipment. It is mainly used for high-precision grinding of various flat surfaces and is widely applied in industries such as mold manufacturing and mechanical part processing. It can make the surface of workpieces achieve extremely high flatness and smoothness, meeting the requirements of various precision production.

Classification and Advantages of Surface Grinding Machines

Key Technical Points of Surface Grinding Machines
Positioning of Surface Grinding Machines
1.The machine tool should reserve an additional space of more than 300 mm beyond its maximum movement space to ensure that it won’t be affected by the surrounding environment during operation. Meanwhile, each foundation bolt should be tightened to ensure the stability of the machine tool. The horizontal error of the table surface in the front-back and left-right directions must be controlled within 0.04/1000 mm. It should be especially noted that if a frequency converter is installed, the requirement for horizontal accuracy will be higher.
2.The level of the worktable surface needs to be inspected and adjusted every three months, and each foundation bolt should be tightened again to maintain the high-precision operation of the machine tool.
Grinding Wheels of Surface Grinding Machines
1.The selected grinding wheels must be able to withstand a peripheral speed of more than 2000 m/min to ensure safety and grinding effect under high-speed operation.
2.It is strictly prohibited to use damaged grinding wheels to prevent dangerous accidents such as wheel bursting during the grinding process.
3.After a new grinding wheel is mounted on the flange, a balancing operation must be carried out to reduce the vibration of the grinding wheel when it rotates at high speed and ensure the grinding accuracy.
4.Before formal grinding, the grinding wheel needs to run idle for 5 minutes so as to observe whether its operating state is normal.
5.There are strict requirements for the feed amount according to the maximum feed stroke of the grinding machine. For grinding machines with a maximum feed stroke below 800 mm, the maximum feed amount is 0.03 mm, while for those above 800 mm, the maximum feed amount is 0.05 mm.
Spindles of Surface Grinding Machines
1.Before installing the grinding wheel, it is necessary to make sure that the spindle rotates in a clockwise direction to avoid poor installation of the grinding wheel or unsatisfactory grinding effect caused by incorrect rotation direction of the spindle.
2.When starting the machine, the spindle must be turned on first. After the spindle operates normally, the flushing device can be turned on to ensure that the grinding wheel is fully cooled during the grinding process.
Hydraulic Devices of Surface Grinding Machines
1.Surface grinding machines should use No. 46 hydraulic oil to ensure the normal operation of the hydraulic system.
2.For a new machine, the hydraulic oil needs to be replaced after three months of use, and then it should be replaced once a year. Meanwhile, the oil tank must be cleaned every time the hydraulic oil is replaced to prevent impurities from damaging the hydraulic system.
3.The hydraulic oil level should be checked every day to ensure that it is between the minimum and maximum lines to maintain the stable operation of the hydraulic system.
4.Before starting the hydraulic motor, it is necessary to make sure that the flow regulating rod (if equipped) is in the closed position to avoid excessive flow from impacting the system at startup.
5.During operation, the magnetic suction device must be turned on first, and then the hydraulic system should be turned on to ensure the stability of the workpiece during the grinding process.
Lubrication Devices of Surface Grinding Machines
1.The lubricating oil should use guide rail lubricating oil with a viscosity of No. 32 – 46 to ensure good lubrication of the guide rails.
2.The oil quantity in the oil tank (pool) should be checked every day to ensure that it is above the minimum line to prevent guide rail wear caused by oil shortage.
3.The smoothness of the guide rail oil circuit should be checked every week to eliminate the occurrence of guide rail oil loss.
4.It is recommended to clean the oil tank once every three months to maintain the cleanliness of the lubricating oil.
5.The grease should be regularly injected as required to ensure good lubrication of relevant components.
Left and Right Mechanisms of Surface Grinding Machines
1.It is prohibited to adjust the left and right strokes when the worktable is in motion to avoid equipment damage or personal injury.
2.When the synchronous belt of the worktable becomes loose, it should be adjusted immediately (this item applies to manual models) to ensure the smoothness and accuracy of the worktable movement.
Flushing and Dust Collection Devices of Surface Grinding Machines
1.The filter screen of the dust collection box should be cleaned once every two weeks to ensure the dust collection effect and reduce the impact of dust on the working environment and equipment.
2.The cooling water tank should be cleaned once a month to ensure the cleanliness of the cooling liquid and good cooling effect.
3.It is strictly prohibited to use an air gun to clean the surface grinding machine to prevent internal parts of the equipment from being damaged by air flow impact or dust from entering key parts.
