High speed machining center holds important seat all along in mould and industry of spare parts treatment, provide treatment with Wu Mo especially. Because its can shorten,machining center of high speed of client choose and buy is of the mould treatment is periodic, can satisfy the requirement of precision, hard cutting, surface roughness. But still many clients use machining center of a high speed to make a variety of traditions,machine, for example rate of heavy cut, low rotate speed, low feed, think machining center of a high speed can shorten cycle of whole pattern production by accident, in fact, still need to consider the following main factors, ability produces the biggest effect. The main shaft cent of the machine tool is designed two kinds for heavy cut and light cutting, the main shaft revolution of machining center of general high speed is divided for every 12, 000 to 20, 000 turn, also the part is amounted to to 40, 000 to 60, 000 turn; Outside the difference that goes up except the design, must the torque of advertent main shaft, wrong application can affect the life of the machine tool directly, the main shaft with for instance low torque should cooperate the cutting tool with lesser diameter, if use the cutting tool with big diameter to machine, can cause greatest harm to main shaft. Watch of machine tool norms can state the power of main shaft and torque, for example the power of main shaft is under 16kW, general proposal cooperates diametical 20mm or smaller cutting tool. By Wu Ji main shaft is designed is the treatment method that is aimed at high speed and light cutting purely, if use undeserved, can cause damage to main shaft. Graph the user of machining center of a lot of high speed often blames 1 cutting tool the life of cutting tool is brief, and the price is high, want to prolong the life of cutting tool, be about to choose appropriate cutting tool to make treatment. Process the data of different hardness, must cooperate appropriate cutting tool and cutting parameter, many operator and process designing staff think rotate speed and feed lead the life that can prolong cutting tool a bit slower by accident, in fact, high speed treatment can machine hardness to amount to the rolled steel of 60HRC, the key is the heat-resisting degree of cutting tool. When edge cuts rolled steel to machine, if scrap wants to amount to the temperature to temper, the hardness that edge place suffers can be reduced, but right now cutting tool wants susceptive temperature quite tall, the likelihood amounts to the high temperature of ℃ of 800 ℃ ~1100, this process is called " effect of high temperature cutting " . The coating on cutting tool is provided high temperature resistant action, and business of every tool production has different specifications. Machining the color that advertent scrap answers when hard steel, when be about to enter phase of effect of high temperature cutting, the color of scrap is yellow, when the treatment that has effect of high temperature cutting, scrap should show purple or blue. Graph 2 graphs 2 can show scrap to be achieved below the different rotate speed of cutting tool those who differ is colour temperature, this is the coating knife of 10mm diameter, from left to right, every are divided 5, 000 to 13, the 000 test results that turn, see the change with colour temperature scrap apparently, colour temperature more tall the bate rate that shows scrap heals big, and hardness of edge place susceptive heals low. The cutter track that promotes the cutting of quality high speed of process designing personnel treatment follows traditional treatment cutter track to have very big difference, if each respect cooperates undeserved, can cause treatment rate loss of slow, cutting tool is reached greatly bright and clean degree of circumstance such as difference. Of the effect of fluid of the application that one-way cutter track processes, different cutting and rotate speed and feed rate cooperate to wait for technology issue, affect the quality of workpiece directly. Machining center of a high speed adds proper Training Within Industry, can get twice the result with half the effort. CNC Milling CNC Machining
