No precision equipment is immune to problems and malfunctions during use, especially after prolonged and frequent use. Minor issues are unavoidable, and precision honing machines are no exception. For example, the high operating temperatures can cause thermal deformation during processing. How can we prevent thermal deformation?

First, we can avoid it from the design perspective. In order to reduce the occurrence of thermal deformation, we can adopt a more reasonable equipment structure during the design. The thermal deformation of equipment is mainly due to heat generation. This requires that the heat source be moved out of the main unit during the design. For example, motors, gearboxes, hydraulic equipment and other spare parts are easy to generate heat. These parts can be placed externally to reduce the probability of the main unit overheating and further reduce thermal deformation.

The spindle is often the core component affecting the machining accuracy of a precision honing machine, but it is also one of the main sources of heat. To reduce thermal deformation caused by high temperatures, more attention should be paid to the selection of bearings, such as choosing precision rolling bearings or hydrostatic bearings, and applying oil mist lubrication to the bearings to effectively control the temperature rise of the spindle during operation. Inside the spindle box, components that easily generate heat, such as conflict clutches, should be minimized.

Precision honing machines are mainly used to hone holes in various workpieces. The honed workpieces are widely used in manufacturing industries such as hydraulic components, automobiles, aerospace, and bearings. To improve honing efficiency and reduce thermal deformation during processing, the above-mentioned measures to mitigate thermal deformation are worth noting.
