What are the reasons that affect the machining of CNC machining tools? -PTJ hardware factory

CNC turning can be equipped with multi-station turret or power turret, with a wide range of processing technology, can process linear cylinders, diagonal cylinders, arcs and various complex workpieces such as threads, slots, worms, with linear interpolation, circle Arc interpolation compensates for various compensation functions and plays a good economic effect in mass production of complex parts. Titanium Machinery is the main product of the company with rotary top, screw, shaft machining, CNC turning, shank shank and collet post. CNC turning must determine the cutting amount of each process when programming. When selecting the cutting amount, we must fully consider the various factors affecting the cutting, correctly select the cutting conditions, and reasonably determine the cutting amount, which can effectively improve the machining quality and output.

The conditions that generally affect the cutting speed, depth and feed rate are the rigidity of machine tools, tools, tools and workpieces; cutting speed, depth of cut, cutting feed rate; workpiece accuracy and surface roughness; tool life expectancy and maximum productivity; cutting fluid Type, cooling method; hardness and heat treatment of workpiece materials; number of workpieces; life of machine tools.
The maximum cutting speed allowed is different for different tool materials. The high-speed steel cutting tool has a high-temperature cutting speed of less than 50m/min, the high-temperature cutting speed of the carbide tool can reach more than 100m/min, and the high-temperature cutting speed of the ceramic tool can be as high as 1000m/min. Workpiece material. The hardness of the workpiece material will affect the cutting speed of the tool. The cutting speed should be reduced when the same tool is used to process hard materials, and the cutting speed can be improved when the soft material is processed.

Mobile parts

Tool life. If the tool life (life) is long, a lower cutting speed should be used. Conversely, a higher cutting speed can be used. Cutting depth and feed rate. The cutting depth and the amount of cutting are large, the cutting resistance is also large, and the cutting heat is increased, so the cutting speed should be reduced. The shape of the tool. The shape of the tool, the size of the angle, and the sharpness of the cutting edge all affect the selection of the cutting speed.

CNC MACHINE

Among the above factors, the cutting speed, cutting depth and cutting feed rate of CNC turning tools are the main factors. The cutting speed directly affects the cutting efficiency. If the cutting speed is too small, the cutting time will be lengthened, and the tool will not be able to perform its function. If the cutting speed is too fast, the cutting time can be shortened, but the tool is likely to generate high heat and affect the life of the tool. Among the factors affecting the cutting speed, the influence of the tool material is the most important. The depth of cut is mainly limited by the rigidity of the machine tool. The cutting depth should be as large as possible if the rigidity of the machine is allowed. If the machining accuracy is not limited, the cutting depth can be equal to the machining allowance of the part.
