Dongguan City, a professional business Unruh CNC cutter, CNC tool holders, knife handle high-speed, ER collet, SK Collet, ER holders, self-tightening chuck, screws, nuts, wrenches and other CNC tool and peripheral products, For more details contact Mr. Liu factors shank speed selection tool when choosing the type and size, the main consideration the following factors: (1) the nature of production in the production of nature here refers to the high-speed batch size bt30 shank parts, mainly from consider the impact on processing costs on tool selection. For example, when mass production using a special tool, it may be cost-effective, high-speed hilt, and in single or small batch production, selection criteria more suitable tool. (2) Type of machine CNC machine tools to complete the process affects the use of the selected tool type (drill, lathe or milling) of. System capable of ensuring the workpiece and tool system rigidity good condition, allowing the use of high-productivity tools, such as high-speed cutting tool holder and a large amount of feed tools. (3) high-speed machining program toolholder shank different high-speed machining program can use different types of tools. Such as hole drilling and processing reamer can also be used for drilling and boring tool for processing. Shank speed selection and material selection of Western and Japanese brands of the same material speed handle, such material containing elemental NI, and other high-speed shank material and does not contain NI. When the holder containing NI element holder under the same conditions is not easy to rust, the heat treatment after the crystal phase structure finer, when the thermal stress is released, the crystal phase structure of the high-speed expansion is relatively small bt40 shank, so long-term use , the shank of small deformation, wear resistance, tensile strength is increased by 20%; Taiwan High Speed ??shank _ Lu a CNC Precision Tool (certified) _ High-speed hilt by Unruh, Dongguan City, a CNC precision tool operation available. Dongguan City Unruh a CNC precision tool operators (www.luyidaoju.com) is Dongguan, a leader in metal molds, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Lu led a CNC precision tool with the staff warmly welcome all inquiries negotiations to create a CNC precision tool Lu a better future.
