There is a close relationship between proficiency in operation and mastery of basic knowledge in the field of CNC lathes. Only by keeping the basic knowledge in mind can we be proficient in the operation process and able to handle emergency situations with ease. Today, our CNC lathe factory will explain to you the three major elements that need to be met for the operation conditions of the CNC lathe cutting center.
The three elements of cutting conditions: cutting speed, feed rate, and cutting depth directly cause tool damage. With the increase of cutting speed, the temperature of the tool tip will rise, resulting in mechanical, chemical, and thermal wear. Not only does the 1:10 conical surface of the tool holder come into contact with the 1:10 conical surface of the machine tool spindle hole, but it also tightly contacts the flange surface of the tool holder with the spindle surface. This double-sided contact system is superior to the 7:24 universal tool holder in high-speed machining, connection rigidity, and coincidence accuracy. Increasing cutting speed will reduce tool life by half. The relationship between feed conditions and wear behind the tool occurs within a very small range. Regular and stable wear is the ideal condition for achieving lifespan. However, in practical operations, the selection of tool life is related to tool wear, changes in the processed size, surface quality, cutting noise, processing heat, and so on. When determining the processing conditions, it is necessary to conduct research based on the actual situation. For difficult to process materials such as stainless steel and heat-resistant alloys
Use coolant or choose a blade with good rigidity.
Before the widespread use of CNC lathes, it is generally necessary to allocate excessive allowances on the blank, especially those containing forged or cast hard skin layers, to be processed on ordinary lathes. If it is necessary to use a CNC lathe for machining, attention should be paid to the flexible arrangement of the program. The polishing edge on a cutting tool refers to a small section of the blade that is ground in the direction of the secondary angle behind the tool edge and parallel to the tool tip. It is mainly used for secondary cutting after cutting, which is equivalent to removing burrs and other scars during precision machining. The purpose is to improve the surface roughness of the workpiece. It is often used on cutting tools for precision machining. The magnitude of expansion increases with the increase of rotation radius and speed, and the stiffness of the tapered connection decreases. Under the action of the pull rod tension, the axial displacement of the tool handle also changes.
The above are the three key elements that need to be met for the operation conditions of CNC lathe cutting centers, compiled and published by CNC lathe manufacturers. We hope that the above description can be helpful for everyone in operating CNC lathes in the future.
