Forming method of gear machining

1. The forming method of gear processing, mainly milling teeth and pulling teeth: (1) Fine cast teeth: cheap pinion gears can be processed in large quantities; (2) die casting machine casting teeth: most of the processing of non-ferrous metal gear; (3) milling machine milling gear: can process straight rack; (4) Gear grinding machine: it can process the gears on the fine mother machine; (5) Cold beating machine tooth: can be processed without chips; 2. Gear processing into the law, mainly hobbing gear:

Processing principle of gear

Gear processing principle, there are two common, profiling processing and fan into (into) processing. 1. Copies processing. The gear machining tool cuts out the tooth groove of the gear, and the "cross-sectional shape" of the tool is the shape of the tooth groove of the gear. When processing gears, there is no gear meshing movement, and the accuracy of the processed gears is low, and the general accuracy is below level 11. 2. Fan Cheng Processing. The gear machining tool itself is "gear or rack", and the gear hob can be "considered" as a rack, which belongs to the rack type tool. During processing, there is a "gear meshing" movement between the gear cutter and the processed gear. Gear cutter tooth profile blade, motion envelope out of the processed gear tooth profile (tooth surface), is an ideal involute, high machining accuracy, common, hobbing, gear shaping, shaving (belong to finishing).

Gear processing methods and specific methods

Involute gear processing method has two categories, one is the profiling method, with a form milling cutter milling gear tooth groove, is the "imitation shape. The other is the model method (the method of development).

Gear processing case

The hardness of hardened steel gears is relatively high, traditional tools are difficult to process, and they are easy to wear quickly. CBN has high hardness, good thermal conductivity, and high oxidation resistance. It does not produce oxidation at 1000 ℃ and does not react with iron-based materials at 1200~1300 ℃.

Cutting tools commonly used in the milling process of CNC machining center

We know that CNC machining center is a major feature of CNC milling machine is the presence or absence of tool library. The machining center generally has 16 or 24 tools in the manipulator tool magazine, which can complete the automatic tool change during the machining process. Different machining processes require different types of tools, but they are all used to cut metal materials, so the tools of the machining center are generally metal cutting tools. The machining center can complete the processing of complex parts such as various discs, plates, threads, shells, cams, molds, etc. through one clamping. A clamping, drilling, milling, boring, reaming, rigid tapping and other processes can be completed. When drilling and milling, you can choose turning tools, planers and milling cutters. Boring cutters, reamers or standard drills are used for hole processing. Tap and thread milling cutter should be selected for thread processing. Gear processing tools include hob, gear shaper, shaving cutter, etc. No matter which kind of tool is composed of clamping part and working part, the clamping part and working part of the integral structure tool are all made on the cutter body. The working part of the tool is to produce and process chips. Some of the working part of the tool is the cutting part, such as turning tools, planers, boring and milling cutters, etc.; some of the working part of the tool includes cutting and calibration parts, such as drills, reamers, reamers, inner surface broaching and taps. The role of the cutting part is to cut the chip with the blade, and the role of the calibration part is to repair the machined surface that has been cut and guide the tool.
