Gear Processing Machine Tool Popular Science Knowledge
Gear processing machine tools are used to manufacture various kinds of gears including spur gears and helical gears. Due to the special shape of the gears, it is difficult to accurately machine the gear profile using traditional machinery. Commonly used processing machines are gear shaping machine and gear hobbing machine.
Gear shaping machine is the most commonly used gear processing machine. The cutting tool of the gear shaping machine is a precision formed involute cutter, usually made of high-speed steel. The cutter is mounted on a spindle and driven by a motor. It is a continuous cutter that generates the required gear profile by cutting away the material from the workpiece.
The main components of gear hobbing machine are worktable, gear cutter, driving gear and motor. The workpiece is mounted on the worktable and fixed in the correct position. The gear cutter is mounted in the lower part of the worktable and is usually in the form of circular gears. The gear cutter is driven by a motor and driven by a driving gear. When the gear cutter rotates, the cutting teeth are in contact with the workpiece and generate the required gear profile.
Gear broaching machine is a special machine tool. It is used to produce precise gear profiles. The cutting tool of the gear broaching machine is a special shaped broach. The broach is mounted in a C-shaped holder and driven by a motor. The broach is forced into the workpiece and generates the required gear profile.
Gear grinding machine is a specialized machine for machining the tooth profile of gears. It uses a grinding wheel as the cutting tool, which is usually made of electroplated diamond or sapphire. The grinding wheel is mounted on a spindle and driven by a motor. The cutting edge of the grinding wheel is in contact with the workpiece and produces the required gear profile.
Gear skiving machine is a special type of machining center. It uses a cutting tool with a composed profile to generate the required gear profile. The cutting tool is mounted in a rotary holder and driven by a motor. The cutting edge of the cutting tool is in contact with the workpiece and produces the required gear profile.
Gear inspection machines are used to check the accuracy of the gear profile. The inspection machines usually consist of a vertical profile projector, a scanning system and a measuring device. The scanner is used to scan the gear profile and the measuring device is used to measure the errors in the gear profile. This way, the accuracy of the gear profile can be checked.
The advances in technology have led to the development of advanced gear processing machine tools, which can produce a variety of gear profiles accurately and quickly. These machines are widely used for the production of all kinds of gears. In order to maximize their efficiency and accuracy, it is important to properly maintain and operate the gear processing machine tools. Regular maintenance such as cleaning and lubricating of the machine as well as timely replacement of the worn-out components can ensure that the machine works reliably.
