Cutting Fluids Used in Cnc Machines

Homepage Blog Cutting Fluids Used in Cnc Machines

Friction occurs during chip removal from the work part in chip manufacturing.

The resulting temperature as a result of this friction has negative effects on both the work part and the cutting tool. Cutting fluids are used to get rid of these effects, eliminate or minimize this resulting heat at the time of cutting. Adverse Effects of Cutting Heat Cause the dimensions of the work part to change. It causes the cutting team to lose its cutting feature in less time. It adversely affects the quality of the processed surfaces. As a result of frequent and unnecessary cutter replacements, the performance of the CNC machine decreases and unnecessary time losses occur. Positive Effects of Cutting Fluid Prevent the cutting team and work part from heating up. It allows the cutting tools to wear less. It helps the cutting team always cut at the same performance.

Quickly removes the resulting chips from the cutting zone. Ensures that the cutting zone is clean for the duration. Ensures that the work area surface is of the desired quality. CNC also as lubries for the machine. In CNC machine tools, it should be noted that the pH value is between 8 and 9.5 so that the cutting fluids do not form rust and bacteria and do not cause irritation in the operator. In cases where the pH value is not paid attention, bacteria may be formed in the system (stinking). Stink occurs after the number of bacteria reaches 107 pcs/ml, and bacterial killer is added to the emulsion to cope with this condition. Biocytes should be added to emulsion at regular intervals to prevent bacterial reproduction and therefore stinking in the system. If the emulsion causes even a small pass, it must be changed urgently. Otherwise, there may be imparable rust problems in CNC machine parts and processed parts. Excessive foaming in cutting fluids can prevent sufficient amounts of fluid from reaching the cutting area, for example, in the CNC lathe, and therefore the lubricant is reduced. Since there are anti-foaming additives in carefully formulated products, there are no foaming problems. Nevertheless, when foaming problems occur, foam extinguisher should be added and the source of the foam should be detected and eliminated. The main causes of foaming are; The water used in emulsion is very soft. System operation under extreme pressure. Mixing detergents used in CNC machine cleaning into the system. It can be listed as pouring the emulsion back into the emulsion tank from a height into the tank.
