Here is a brief introduction to several machine tools, namely drilling machine, grinder, boring machine, and planer.
Drilling machine
Drilling machine refers to a machine tool that mainly uses drill bits to process holes in workpieces. Usually the rotation of the drill bit is the main motion, and the axial movement of the drill bit is the feed motion. The drilling machine has a simple structure and relatively low processing accuracy. It can drill through holes and blind holes. By replacing special tools, it can expand, countersink, ream, or tap. During the machining process, the workpiece does not move, the tool is moved, the center of the tool is aligned with the center of the hole, and the tool is rotated (main motion). The characteristic of a drilling machine is that the workpiece is fixed and the tool rotates.
Grinding machine
A grinder (grinding machine) is a machine tool that uses abrasive tools to grind the surface of a workpiece. Most grinders use high-speed rotating grinding wheels for grinding, and a few use other abrasive tools and free abrasives such as whetstones and abrasive belts, such as honing machine, super-finishing machine tool, abrasive belt grinder, grinder and polishing machine.
Boring machine
A boring machine is a machine tool that mainly uses a boring tool to boring existing pre-made holes in the workpiece. Usually, the rotation of the boring tool is the main motion, and the movement of the boring tool or the workpiece is the feed motion. It is mainly used for processing high-precision holes or finishing multiple holes in one positioning. In addition, it can also be used to process other processing surfaces related to hole finishing, such as threads and processing outer circles and end faces. Drilling, milling, and cutting can also be performed using different tools and accessories. Its processing accuracy and surface quality are higher than those of a drilling machine. The boring machine is the main equipment for processing large box parts.
Planer
Planer is a linear motion machine tool that uses a planer to plan the plane, groove or formed surface of the workpiece. Planer processing has simpler tools but lower productivity (except for processing long and narrow planes), so it is mainly used for single parts, small batch production and machine repair workshops, and is often replaced by milling machines in mass production.
