The turning point of Swiss-type machine tools | Swiss type CNC lathes
Over time, SMP has become more proficient in Swiss-type machine tool processing technology and the use of other multi-function machine tools. The company has also encountered many situations in which the experience learned in one field can be copied to another. A field. Here are some research results:
Reverse machining: Swiss-type machine tools are always known for being able to perform reverse machining on parts of various shapes after the parts are separated from the blanks. However, when SMP purchased its first Citizen L20 machine tool in 1998, there were only two on the turret. One or three tool positions, which was very common at the time. According to Slabe, most Swiss-type machine tools, especially Citizen, have a lot of tool positions on the turret. This problem is solved because the machine design is upgraded. However, it is this early experience with Swiss-type machining that makes Slabe want to complete the same type of machining work in one setting, so that it can be implemented on the larger and more powerful Nakamura multi-tasking machine he bought. Any kind of reverse machining operations. This technology has been upgraded on these two types of machine tools, and now Slabe can perform reverse machining in many different ways on all parts produced by his company.
High-pressure coolant: SMP realized the value of the high-pressure coolant system after installing its first Swiss-type machine tool. Due to the small size and light weight of machining chips produced by Swiss-type machine tools, the coolant system can basically "sweep" the chips from the work stroke during each machining process. However, it can perform much more important functions on larger multi-task machine tools, because it is necessary to use 1000 lb/in2(1 lb/ in2=0.00 689 MPa) system. When the coolant nozzle is in the correct position, it can reduce tool wear and make the tool more predictable, because the lubricity and temperature of the coolant can cause the cutting tool to wear at a more standard speed.
Multi-tool holder: Slabe advocates the use of multi-tool holders, which can increase the tool capacity at each position of the turret. He will use these toolholders whenever possible on Swiss-type machine tools and multi-function machines. In fact, he designed a three-tool holder for his company's internal use through various experiments, and it has been independently listed on the market.
Deburring: In this regard, SMP has achieved its goal of turning burr removal into a part of the CNC machine tool processing process, rather than auxiliary offline operations that are done by vibration or manually. Machining a specific shape in the first position to machine the last path is part of the success of the method, which is true for its Swiss-type and multi-function machine tools. For example, a hole is drilled through the center of the spindle length. The part requires a series of holes to be drilled at a right angle perpendicular to the through hole, but burrs will be left on the inner edge of the hole. Using the original tool, Slabe drilled a through hole and withdrew the tool from the through hole. Since the tool is already at the required position and the wear point is the same as the wear point after the last path, there is no need to perform secondary processing operations to remove burrs.
Near-final blanks: Since Swiss-type machine tools are most suitable for processing round blanks, Slabe must consider how to start processing from a shape that is already close to the final shape to ensure that the remaining part of the processing is minimal, and it is as cost-effective and competitive as possible . This attempt made him rethink the form and source of blanks used in HMC and VMC, whether it is castings, extrusions, forgings or pre-processed blanks. By starting processing from the near-final shape, the time spent in rough machining of the parts is shortened as much as possible, thereby reducing the cost of each workpiece, and achieving the final processing more quickly. One way for SMP to achieve this goal is to use the powerful 94 000 lb/in2 HyperJet water jet from Flow to cut near-final blanks derived from the blank, which means that the multi-axis machining center must cut less s material.
When it comes to tools, SMP tries to use standardized tools whenever possible. The company has been able to find almost all the tools needed for Swiss-type and multi-function machine tools to use as inventory and eliminate search time.
Outlook
In addition to the huge advantages of being able to process a part on a machine tool, the Swiss-type machine tool has also changed the way SMP company processes smaller parts, such as the pins it once purchased from another company. The experience with Swiss-type machine tools allows the company to remain as efficient and self-sufficient as possible.
"Now we have a total of seven Swiss-type lathes for smaller parts, various multi-spindle and multi-turret machining centers suitable for parts with a diameter of up to 8 in, horizontal and vertical machining centers with five-axis attachments, Wear-resistant water spray equipment, rapid-processing machine tools for prototype parts, and robots used to feed and position parts in high-volume applications." Slabe said, "These machine tools are purchased based on our experience in Swiss-type machining In fact, the first machine tool is still running, so this is an investment that can really pay off."
