Classification and characteristics of powder metallurgy taps There are many kinds of powder metallurgy taps. How to choose? Powder metallurgy taps are commonly used tools for processing internal threads. According to their shapes, they can be divided into spiral fluted taps, side oblique taps, straight fluted taps and pipe thread taps. According to the use environment, they can be divided into manual powder metallurgy taps and electric powder metallurgy taps.

There are many kinds of powder metallurgy? As a commonly used tool for comprehensive upgrading of internal rotation type, powder metallurgy taps can be divided into spiral groove taps, side tilting ports, straight groove ports and tube rotation type ports according to their shapes, and can also be divided into manual powder metallurgy taps and electric powder metallurgy taps according to the operating environment. According to specifications can be divided into metric faucet, N type faucet and powder metallurgy faucet. TAP is also the main tool for fully upgraded process tapping. So how to choose powder metallurgy? Today I want to share with you a guide to choosing the right powder metallurgy to help you choose the right one. Cutting powder metallurgy tap straight groove port: extrusion to fully upgrade through hole and blind hole. There are iron filings in the sink of the faucet. The quality of the comprehensive upgrade of the rotary type after the comprehensive upgrade is not high, and more than squeeze to the comprehensive upgrade of gray cast iron and other short chips. Rotary port: usually we can only squeeze to the through hole, the aspect ratio can reach 3D ~ 3.5 D, followed by iron filings discharge, the plane segmentation comprehensive upgrade torque is small, the rotary comprehensive upgrade surface work quality is high, also known as side port or end port. During the planar segmentation, make sure that all planar segments are penetrated, otherwise the teeth will collapse.

Powder metallurgy taps can be extruded to fully upgraded through holes and blind holes, and teeth are formed by plastic deformation of materials, which can only be extruded to fully upgraded plastic materials.powder metallurgy tapIt has the following main features: the rotating type is fully upgraded through the plastic deformation of the workpiece; the port has a large cross-sectional area, high strength, and is not easy to break. The cutting speed is higher than the cutting port, and the productivity is increased accordingly; the comprehensive upgrade of cold extrusion can effectively improve the mechanical system performance of the fully upgraded rotating surface, with high surface roughness, and improve the working strength, wear resistance and corrosion resistance of the rotating type; no Chip processing.

There are two data types of structure: no oil groove extrusion port is only added to the vertical management of the blind hole. Powder metallurgy port structure design parameters, appearance size, total length: Under working and living conditions where some problems require a special education extension, the length of the groove should be paid attention. The accuracy of the rotary part: according to their own specific rotary standard, the ISO 1/3 rating of the metric rotary is equivalent to our national safety standard H1/2/3 rating, but should pay attention to the manufacturer's internal risk control system standards. Cutting Port: The cutting part of the port forms a business model with fixed capital assets of the local company. In general, the longer the planar split port, the better the port life. Groove type: affects the formation and discharge of iron filings, which is usually kept secret by each manufacturer. Front and rear angles: When the port becomes sharper, the plane division resistance will be significantly reduced, but the strength and stability of the tooth tip will be reduced. The rear angle is the rear angle of the notch. Number of grooves: the increase of the number of grooves and plane dividing blades can get effective methods to improve the service life of the port, but it will compress the research space of chip removal, which is still at a disadvantage in chip removal ability. Powder metallurgy ports made of tool steel: mainly consists of squeezing into manual plane split ports, which are now less commonly known. Cobalt-free high-speed steel: It is currently widely used as a port material.
