Which Company in China Provides High-quality Internal Groove Processing Tool Services

Kunshan Meiyaxing Hardware Machinery Co., Ltd. is a direct branch of Hong Kong Meiya International Trading Company in China. It has its own tool brand: MANF, engaged in CNC tool sales and operation services. It provides tungsten steel milling cutters, milling blades, turning blades, grooving and cutting blades, drilling and boring blades, multi-functional blades, threading blades and other indexable blades and their matching tool holders and cutter discs. Internal groove processing has always been a common problem in mechanical processing, so the selection of internal groove processing tools has become crucial.
According to the processing material Different, internal grooving tools are mainly divided into metal internal grooving tools and non-metallic internal grooving tools.
Metal internal grooving tools are mostly made of high-strength materials such as cemented carbide and high-speed steel. Cemented carbide has the advantages of high hardness, good wear resistance, and strong heat resistance. It can maintain good edge sharpness under high-speed cutting conditions and is suitable for processing various ferrous and non-ferrous metals, such as steel, aluminum alloy, etc. When cutting steel materials, cemented carbide internal grooving tools can withstand greater cutting forces to ensure processing accuracy and efficiency. High-speed steel internal grooving tools have better toughness and machinability, and the hardness can reach 10000 after heat treatment. 62-67HRC, commonly used in some metal processing scenarios that require high tool toughness and relatively low cutting speed, such as the inner groove processing of stainless steel parts in precision instruments.
Non-metallic inner groove cutters are mainly used to process non-metallic materials such as plastics, rubber, and ceramics. This type of tool usually has a higher edge sharpness and chip removal performance to prevent problems such as chip adhesion and tearing of the workpiece surface when processing soft materials. For example, when processing the inner groove of plastic parts, using sharp high-speed steel or carbide coated tools can reduce the deformation and burr generation of plastics; for rubber materials, special rubber inner groove cutters have a more Round and smooth, it can effectively avoid rubber tearing and ensure the flatness of the processed surface.
(II) Classification by processing technology
From the perspective of processing technology, inner groove processing tools can be further divided into turning inner groove tools, milling inner groove tools, grinding inner groove tools, etc.
Turning inner groove tools are often used for inner groove processing of rotating parts, such as shafts and sleeve parts. When it works, the workpiece performs the main rotation motion, and the turning inner groove tool performs the axial or radial feed motion, and forms a groove on the inner surface of the workpiece through continuous cutting. This tool has a relatively simple structure and strong versatility, and can adapt to the processing of inner grooves of different diameters and depths. In terms of processing accuracy, ordinary turning inner groove tools can reach IT8 - IT10 level, the surface roughness Ra can reach 3.2 - 6.3μm; if precision turning technology and high-performance tools are used, the accuracy can be improved to IT6 - IT7 level, and the surface roughness Ra can be reduced to 0.8 - 1.6μm, which is widely used in the manufacturing of inner grooves of automotive parts and general mechanical parts.
Milling inner groove cutters are suitable for processing inner grooves of complex shapes such as planes and curved surfaces. Through the rotation of the milling cutter and the feed motion of the workpiece, the layered cutting of the material is achieved. There are many types of milling inner groove cutters, including end mills, keyway milling cutters, ball end mills, etc. End mills can process straight wall inner grooves, keyway milling cutters are specifically used for processing keyways, and ball end mills are good at processing inner grooves with curved surface contours. In the field of mold manufacturing, in order to process complex internal cooling water channels and demoulding bevel grooves in the cavity, multi-axis linkage machining centers are often used in conjunction with various milling internal groove cutters to achieve high-precision and complex shape internal groove processing, with processing accuracy up to IT7-IT9 level and surface roughness Ra 0.8-3.2μm.
Grinding internal groove cutters are mainly used for internal grooves with extremely high processing accuracy and surface quality requirements, such as cooling internal grooves of aircraft engine blades and internal raceway grooves of high-precision bearings. Grinding processing belongs to micro-cutting, which removes extremely thin material layers through the high-speed rotation of the grinding wheel and the relative movement of the workpiece, thereby achieving high-precision and high-finish processing effects. Internal cylindrical grinding internal groove cutters can process internal grooves with smaller apertures and deeper depths, while surface grinding internal groove cutters are suitable for processing flat internal grooves or shallow grooves. The precision of the internal groove after grinding can be stabilized at IT5-IT6 level, with a surface roughness of Ra 0.2-0.8μm, meeting the stringent requirements of high-end equipment manufacturing industry for precision internal grooves of parts.
