5, broach: efficient choice in mass production

Broach is a forming tool used for broaching. It is unique in that there are multiple rows of teeth on the surface of the tool, and the size and shape of each row of teeth increase and change from the cut end to the cut end in turn. When the broach is broaching, each knife tooth is like a miniature craftsman, cutting a certain thickness of metal from the workpiece, and finally getting the required size and shape. Broaching tools are often used in batch and mass production for efficient machining of round holes, spline holes, keyways, as well as flat and formed surfaces. According to the different parts of the processing surface, it is divided into internal broach and external broach; According to the different ways of working force, it is divided into broach and push knife. The pusher is often used to calibrate the shaped hole after heat treatment and plays an important role in ensuring the accuracy of the hole.

6, gear tool: gear processing artifact

Gear machining plays an important role in machinery manufacturing, and gear tool is the key to realize high precision gear machining.

Gear hob, according to the helical gear pair meshing principle, cutting gear by generating method. It is divided into many types according to the processing nature, such as fine cutting hob for the final precision machining of gear; The rough cutting hob plays an important role in the preliminary machining stage of the gear. Pre-shaving hob, pre-scraping hob, pre-extrusion hob, pre-grinding hob, stay grinding hob, chamfering hob, etc., respectively for different processing stages and specific needs, to ensure the gear profile accuracy and surface quality.

A gear shaper cutter is a gear shaped or rack shaped gear machining tool. It is used for machining straight and helical gears with internal and external meshing by the development method. The gear shaper cutter is characterized in that it can process gears with shoulder gear, multi-coupled gear and double-helical gear with no empty slot. Disk, bowl, barrel and taper shaper cutter are suitable for different processing scenarios. Disk shaper cutter is the most widely used for machining straight, helical and herringbone gears with internal and external meshing. The bowl-shaped gear shaper cutter is suitable for machining internal and external meshing spur gears with shoulders and multiple links, and its unique design does not hinder the machining process; Cylindrical gear shaper cutter is mainly used for machining internal gear and external gear with small modulus. It is connected with the main shaft of gear shaper machine through the internal hole thread to ensure the stability of processing. Taper shank gear shaper cutter focuses on the machining of internally engaged straight and helical gears.

The shaving tool is provided with a number of narrow grooves forming a cutting edge on the tooth surface, and the gear shape of the workpiece is processed according to the meshing principle of the helical gear. It refines the gear after the gear hobbing and shaper. By cutting the whisker-like fine chips, the gear tooth shape is more accurate and the surface is smoother, thus improving the transmission accuracy and reliability of the gear.

7, grinding wheel: the backbone of grinding processing

The grinding wheel, also known as the consolidated abrasive tool, is a binder that consolidates the ordinary abrasive into a certain shape (mostly round, with a central hole) and has a certain strength of the consolidated abrasive tool. Generally composed of abrasives, binders and pores, these three parts are called the three elements of consolidated abrasives. According to the different classification of bond, common ceramic (bond) grinding wheel, resin (bond) grinding wheel, rubber (bond) grinding wheel. Grinding wheel is the largest amount of abrasive tools, the most widely used one, the use of high-speed rotation, can be used for metal or non-metal workpiece, the outer circle, the inner circle, the plane and a variety of profiles, such as rough grinding, semi-fine grinding and fine grinding, as well as grooving and cutting and other processing.
