The use of 5-axis machining machine, optimizing the length of the tool to improve machine tool accuracy and processing capacity is critical. Tom Mullen founded TNT EDM Machine Tool Company (founded in Plymouth, Michigan) in 1978 when the company had a floor area of ​​only 300m2 and employs 4 people. Mr. Mullen, the company's president, has taken a strong management approach to developing the company into a consortium. Today, the company covers an area of ​​more than 7,000 square meters (and continues to grow) with 40 employees and everyone is working hard. Atmosphere of work. The company is not so much a machining shop, it is more like an executive body. The design of the TNT plant reflects the extraordinary style of Mr. Mullen. The company's office and production workshop into one, intimate. You can see buildings made of selected natural wood and polished granite everywhere. From the walkway covered with granite floors, through the arches of the maple decoration can enter the plant. There, you can see the high-speed cutting of scrap from the machine tool; smells of coolant and oil from the air; the finished part quickly pops up from the machine. In short, from the processing plant can reflect the company's focus on quality and precision of the atmosphere, all of this will certainly give customers a deep impression. Mr. Mullen said: "To be successful, three things are required: authentic customer, right person, and sophisticated equipment. The products we design and manufacture demonstrate to our customers our strengths and our factory facilities for our employees They provide an extremely comfortable working environment. "Figure 1 TNT EDM was created as a small EDM shop. Since then, it has been developing continuously and introduced 5 sets of 5-axis linkage machine tools successively for the production and processing of parts. At the very beginning, TNT strictly speaking was only an EDM processing plant, mainly serving the injection mold industry. Mr. Mullen said: "I started out with 4 EDM countersink machines and then expanded rapidly with the addition of EDM wire EDM machines, and we added machining capacity to take on more EDM processing business. Two years ago, With the addition of our 5-axis machining lathe, our production and processing capabilities have impressed us a lot, and strictly speaking, almost all of the machining projects we undertake now are machining-related. "In difficult application areas, The pursuit of excellence is Mr. Mullen's business philosophy. He said: "We used to work for 50 clients 10 years ago, but now we have consciously chosen only 10 customers, of which 4 are only responsible for our fragmented work pieces. We want to eliminate the distractions so we Do their best to serve the most loyal and valued customers, and instead they send some of their most challenging jobs to us. "Mr. Mullen's applications in this context include forging parts , Complex automotive components, including powder metallurgy parts, molds for injection molding plants, impellers and propeller parts used by the aerospace industry. In 2000, the company bought the first 5-axis machine tool and added four more. The rapid development of this business unit prompted us to develop a new plan to phase out the old 3-axis and 4-axis machine tools to give full play to the overall working ability of a 5-axis machine tool. All five-axis machining tasks were performed on five C-series machining centers provided by Hermle Corporation, four of which were C600U models and the other of which was a C800U model. "We did not have enough experience buying the first machine, so we were looking for outside help," said Mr. Mullen. "Given the type of parts we need to make, we recommend that Hermle keep its tight tolerances from processing hard materials Based on their inherent flexibility in design and capability, 100% of the parts we process are complex and 90% of the parts are made of hard materials. "Figure 2 TNT EDM's business scope includes forging parts And complex automotive parts, including powder metallurgy parts, molds used in injection molding plants and parts for impellers and propellers for aerospace applications Leon Carpenter is a project manager and programmer at TNT and is an associate of the company's nine-year-old veteran , In various processing areas have some experience. "The machining of parts on the Hermle machine keeps us well because the machine is based on the Heindenhein control system and has many features on the machine itself," said the control system, with easy-to-learn features for tilting axis machining and Multi-axis machining. The machine is equipped with a contact test probe that allows me to remove part tolerances before machining the part from the machine. For example, in combination with a quick-change tool and using the A-axis function that rotates bidirectionally by 110 °, Hermle The company's machine tool minimizes airless time. "Mr. Carpenter found that the real value of a 5-axis machine tool outperforms its ability to produce 5-axis parts. By producing normal 3-axis and 4-axis parts on a 5-axis machine, he can determine the amount of time and money that can be saved by looking at the magnified image. Carpenter said: "Tooling is one of the biggest consumers when it comes to milling of hard materials, and the more complicated parts we manufacture, the more time we need to extend the tooling to work on the machine Life. With 5-axis machining lathe, to optimize the length of the tool to improve the accuracy and machining capacity of the machine is critical. If the workpiece is processed steel, the hardness should be 52 ~ 62R. To extend the life of the tool Another company One way is to reduce the working speed of a machine tool: the spindle speed of a 5-axis machine tool can reach 16000 r / min, but the company's standard machine speed is 12000 r / min. "The reasonable speed plus the rigidity of the spindle Is to maintain the accuracy of the machine tool to prevent damage and extend the life of a major tool guarantee. Mr. Carpenter continues: "There is no doubt that 3-axis or 4-axis machining of parts on a 5-axis machine is one of the most compelling reasons for any machining shop to save part time and tool set-up time. Because the machine is versatile and flexible, you can access parts from many orientations and angles. In general, the parts are relatively easy to set up, so you can save a lot of time. For example, when machining a mold for a car linkage, the magnetic chuck table allows for the simultaneous clamping of two blanks and the use of night work time to machine two parts at a time. When you are limited to the processing of highly complex parts, the use of such programs can really save the purpose. "" I think there is no reason to buy any other machine than to buy a 5-axis machine. I suggest that any processing shop should purchase 5-axis machining lathe without exception. Mullen believes there is another reason to maximize the versatility of a machine tool: "When I looked at the work being machined today, I compared it with what I did five years ago, and obviously found that Processing parts more and more complex. In addition, the processing of the material hardness is also rising. Obviously, we can not rely on the kind of work we did yesterday, if we wanted to continue to increase production and maintain high standards. We need a machine tool that will bring us into tomorrow, and for our time being, a 5-axis machining machine. "
