Grinding is mankind since ancient times to know an ancient technique, Paleolithic CNC drilling equipment, polished stone is used this technique. Later, with the use of multi-axis CNC metal utensils drilling equipment, and promote the development of grinding technology. However, the design of the grinding machine or something truly modern adjustable CNC drilling equipment, even in the early 19th century, CNC drilling equipment manufacturers, it is still a natural by rotating grindstone, make contact with objects grinding process. The first grinder (1864) in 1864, the United States made the world's first grinder, which is a device in the lathe turret installed on the wheel apron, and it has automatic transmission. After 12 years, the United States, Brown invented the modern grinders near universal grinder. Artificial grindstone - Wheel of birth (1892) artificial grindstone demand will rise. How to develop a more wear-resistant than natural grindstone millstone it? In 1892, Americans Acheson successful trial with coke and sand made of silicon carbide, which is now known as an artificial grindstone C abrasive; two years later, as the main component alumina abrasive A trial again success, so that they will have a grinder more widely used. Later, due to the bearings, to further improve the rail portion of the increasingly high precision grinding machine, and the development of the professional direction, there has been internal grinder, surface grinder, roll grinders, gear grinders, universal grinders and so on. Cutting machine by the relative motion between the tool and the workpiece to achieve, its movement can be divided into surface and supplementary motor sports categories. Movement is formed on the surface of the workpiece to obtain the moving surface shape and size required, which includes the main movement, the feed movement and the cutting motion. Main sport is played a major role in the release of excess material from the workpiece blank exercise, it may be a rotary motion artifacts (such as turning), linear motion (as in the gantry planer planing), may also be the rotational motion of the tool (eg milling and drilling) or linear motion (such as slotting and broaching); feed movement is part of the tool and the workpiece to be machined is moving towards each other, so that the cutting motion to proceed, such as when turning cylindrical turret apron along Machine Tool moving the like; cut into a certain movement is the movement of the tool cutting depth of the workpiece surface, its role is cut in each cutting stroke from a certain thickness of the surface materials, such as when turning toolholder transversely cut into small cylindrical movement.
