Manufacturers supply various size 1 -3 grade cast iron crossed platform

Manufacturers supply various size 1 -3 grade cast iron platform crossed crossed platform accuracy: Sea Botou Tools Manufacturing Co., according to the national standard verification procedures, namely, 0,1,2,3 four grades. Crossed flat iron, cast iron crossed platform is to check the measurement reference machine parts flatness, straightness tolerance and other forms can also be used for grinding parts marking, installation of equipment and other purposes. It can also be used for marking, welding and grinding processing and measurement general parts and precision components and so on. Produced by cast iron crossed platform are exported overseas, we will be in "price and quality" Double Excellence "integrity and service" win-win business philosophy and dedication to our customers. Cast iron crossed platform machinery production in order to stabilize casting size, often casting long stand at room temperature before cutting. This measure is also known as aging. However, this limitation does not belong to the metal heat treatment process. Cast iron platform as the cast product, according to the principle of casting, iron casting platform certainly exists after the completion of the internal stress, it should be placed or room temperature is maintained at a higher temperature, its performance, shape, size changes with time. The use of the workpiece is heated to a higher temperature and longer time for aging treatment aging treatment process, known as artificial aging treatment, when the workpiece stand at room temperature for prolonged storage conditions or natural aging phenomenon occurs, called natural aging treatment. The purpose of aging, eliminate internal stress of the workpiece, stable organization and size, to improve the mechanical properties. For the time aging process, of course, the longer the better, but the reality of the production can not be realized, when real production 2-3 months aging treatment should be done. This discovery aroused great interest in engineering. Then people have been found that can employ aging treatment to strengthen aluminum alloy, copper alloy and iron-based alloys, and create a general quench hardening steel have the essential difference of new and enhanced way - aging strengthening.
