Which CNC Machining Performance will be Affected by Temperature?

Overheating and overcooling of temperature will have certain influences: "causing uneven temperature rise in various parts of the machine tool", "workpiece deformation", "influencing accuracy" and other issues. This article mainly describes how the temperature in winter affects CNC machining performance. Explore it!

How is the performance of CNC machine tools affected by temperature?

The machine tool is affected by changes in the workshop environment temperature, motor heating, mechanical movement friction heating, cutting heat, and cooling medium, resulting in uneven temperature rise of all parts of the machine tool, resulting in changes in machine tool morphology and machining accuracy. Temperature is always a factor in machining operations, because it not only affects the machine, but also the processed material.

Influence of temperature on tolerance

The influence of temperature is not only affected the tools and equipment of CNC machine tools, but also does not affect the machining of different materials. For example, when a 25.4cm aluminum rod changes from a place where it is stored at 25°C to 31°C, its material will grow by as much as 0.1mm. The changes brought about by this temperature will affect the profit and loss between production operations.

Almost all other materials are affected by the temperature of the environment where they are placed. Therefore, we need to properly evaluate the temperature conditions before machining operations.
 

Cold system and heat system of CNC tools

The influence of temperature in different regions of China is also different; for example, the seasonal temperature variation in the Yangtze River Delta region is about 45°C, and the day and night temperature changes are about 5-12°C. The temperature gradient in the machining workshop does not change much. In contrast, in the Northeast, the seasonal temperature difference can reach 60°C, and the day-night variation is about 8-15°C. Therefore, in the long run, it will be worthwhile to take the time to evaluate and determine the best practices for maintaining the integrity of CNC machine tools and workpiece materials.

The cutting methods of cold-system tools and hot-system tools are different, and the impact on machining equipment is also different. In order to ensure the correct output, so as to avoid mechanical failure or the quality of the finished parts from being affected. Therefore, cleaning agents, lubricants, filters and many other machine parts must be adjusted according to the operating conditions of the machine.

Summarize      

No one knows the impact of temperature changes better than the CNC machining manufacturer in the area where you need to process the parts. They will formulate a reasonable plan based on the information, experience and skills.

Whenever there are questions or concerns, it is best to get answers from CNC experts before continuing. We have more than 25 years of technical engineers to develop professional solutions for you.
