The main function of small end mills in the age of manufacturing competitiveness for speed and precision is the highest quality of workpiece and performance. Nowadays, end mills are being invented and developed with innovations to connect them to the new form of manufacturing in the age of Industry 4.0 continuously.
Regarding the End Mill for Copper Electrode, NS Tool, the leading company from Japan and the manufacturer of small end mills with high effectiveness, has invented Long Neck End Mill for Copper Electrode which can help achieve high quality processing surface and long life in machining work.
Currently, there are 2 types of Long Neck End Mill for Copper Electrode, the latest innovations by NS TOOL: Long Neck End Mill DHR237 and Long Neck Ball End Mill DRB230.
Long Neck End Mill for Copper Electrode DHR237 comes with sharpness, shearing ability and strong edge. The tool shape is well-designed with micro gash land for usage. It can continue cutting while the strength of the corner part is increased. This developed design is the most suitable cutting edge shape for milling copper because it has fine cutting ability to minimize generating burrs and high chip disposal.
In addition, the 37.5° helix angle helps achieve high quality processing surface because 37.5° is the best helix angle to achieve the best shearing ability as well as fine cutting surface. Moreover, the flute length L/D=2 is the right balance for rigidity and usability of square end mills. With specialized edge profile and DLC coating, the result of the machining on copper electrode is of high quality and another benefit is long life while processing on tough materials such as Copper Tungsten.
Long Neck Ball End Mill for Copper Electrode DRB230 comes with high accuracy edge profile and sharpness shearing ability. Because the processing deals with highly viscous copper alloy, the edge profile with sharpness shearing ability can help achieve burr suppression and high precision. Moreover, the peripheral cutting edge is really seamless; hence, higher quality machining by edge profile.
DRB203 can process 5 workpieces with only one tool and there is only little change in dimensions and surface quality. Therefore, it ensures an outstanding surface quality.
These 2 small end mills are the products which NS TOOL has invented and developed to meet the requirements of customers in the industries to keep up-to-date with the changes in the technological world, especially in the age of INDUSTRY 4.0.
