The Sander needs regular lubrication to maintain a good working state. The selection of lubricants requires several aspects: technical requirements for the workpiece processing surface, materials of the Sander, abrasive particle size, grinding methods and process flow.
For example, the Sander uses large size abrasive for rough grinding, and the margin is large. If the lubricant with larger external tension coefficient and viscosity is selected, the grinding efficiency will be greatly reduced due to the thicker oil film between the workpiece and the outer surface of the Sander, the higher oil viscosity and buoyancy, the shallow pressing of abrasive particles, and the slow cutting.
On the contrary, if the Sander chooses the lubricant with small external tension coefficient and low viscosity, it will accelerate the crushing of abrasive grains, and also cannot guarantee higher grinding efficiency. In this way, it is necessary to choose a lubricant with moderate viscosity according to the specific situation, which has a good effect on the equipment.
When selecting lubricants for the Sander, the selected products are required to have good lubrication and cooling effects, viscosity and dilution capabilities, so as to ensure that the forward grinding has the conditions of no accumulation and uniform distribution, so that the abrasive particles can attach to the surface of the horizontal Sander.
At the same time, try to choose lubricants that are less affected by temperature changes and require them to be easy to organize. In addition, the lubricant shall be suitable for different processing speeds of the Sander and increase the surface finish of the workpiece without damage. If lubricants can accelerate grinding speed and increase grinding efficiency.
