With the development of China's manufacturing industry and the application of CNC machine tools, the overall level of domestic equipment has been greatly improved, and foreign advanced processing concepts have been continuously introduced into the country, which has actually been used for high-efficiency tools. The application has created a good platform.
The so-called efficient tool, we think it should be understood from the following two aspects:
One is to use a higher amount of cutting. Through the application of high-performance cutting materials and the optimization of the design of the tool structure, the tool can be applied to higher cutting speeds and feeds;
The second is to reduce the auxiliary time. By analyzing the actual machining process, we find that the auxiliary time of the machine tool also occupies an important ratio compared to the cutting time. Therefore, another direction to improve efficiency is to properly combine some processes on a tool and reduce the non-cutting time by reducing the tool change time as much as possible.
As the most well-known company in the industry for non-standard tool solutions, Marpa has always improved processing efficiency as the primary goal of serving customers and has a range of high-performance products to meet the different needs of customers:
As a finishing tool for Marpai, the bar-type tool guarantees excellent dimensional accuracy, shape tolerance and surface roughness of the machined hole. With "First part, good part" we can greatly reduce the customer's processing. Auxiliary time; a new development tool TSW and TFB combined with vertical blade and guide bar tool design, where TSW rough boring tool is a roughing tool using convex triangular vertical blade, because the tool is in processing The blade can be supported by itself in the machined hole, plus the positive rake cutting design allows for large depths of cut while using large feed rates without vibration. TFB is a finishing boring tool for IT7 to IT8 precision holes. Because it is a multi-tooth design, it can increase the efficiency by 6~8 times compared with the ordinary single-edged boring tool.
For aluminum alloy parts processing, Marpa has a very complete diamond product line. For flat machining, Marpa offers face milling cutters with cutting speeds up to 9000 m/min and HP series end mills with metal removal rates up to 6.5 L/min. In terms of hole processing, Marpa also has many years of experience, can design non-standard hole machining tools according to customer requirements; standard HPR reamer series with diameter range from D3.98mm~D65mm using Marpa HFS interface, especially suitable For high-speed machining, the knife has a design for through holes, blind holes and different workpiece materials, while the HFS interface ensures fast replacement of the reamer head with repeatability of 0.003mm.
In the field of solid carbide tools, in addition to providing a complete range of drills in accordance with DIN standards, Marpa can also provide a four-blade, GIGA drill with at least a doubling of feed rate and direct drilling to achieve IT7 accuracy. Drill reamer products; for solid carbide drills, as the price of cemented carbide materials continues to rise, the pressure on material costs is increasing, so Marpa developed the TTD drill bit, which is a steel arbor The drill bit of the combined carbide tip is connected through the TTS's ratchet plate interface to ensure good torque transmission and self-centering performance. Compared with solid carbide drills, the performance is the same but the cost is greatly reduced; the unfolding tools that use the drawbar drive to achieve the compound motion of the tool used to be used on special machine tools. Now, for the wide application of machining centers, Marpa has already adopted this concept. Transplanted in the machining center, the function of the rod drive is realized by mechanical, coolant and centrifugal force.
However, in the communication with customers, we also noticed that many customers only pay attention to the purchase price of the tool in the application and selection of the tool, and neglect the comprehensive cost in the whole process. In fact, the cost in the process includes not only the cost of the tool, but also the cost of the machine tool and other auxiliary work such as inspection and tool adjustment. Through the application of high-efficiency tools, we can reduce the overall cost by improving machine utilization, improving process stability, tool life and reducing other adjustment time.
