A country's industry to revive the advanced manufacturing technologies can not be separated, and mold will undoubtedly be ranked first in the advanced manufacturing technologies. Therefore, high and low levels of mold technology to measure a country's manufacturing sector has become an important indicator of the level. Manufactured in China to realize the dream of power, must die first. China Die & Mould Industry Association, said the Secretary-General Wu Bing-shu, from Car The heart of the generator of the cylinder casting to the automotive body stamping, hot steel plate forming the new super model material, the core components to the domestic production of cars, have to die drive. Mold can be equipped with a car equipped with an important component.
Mold is the basis for industrial production technology and equipment. In Electronic , Automotive, electrical, instrumentation, Home Appliances And communications products, 60%? 80% of the parts have to rely on molding. The level of mold, and its use during processing Abrasive Abrasive product quality are inextricably linked. Now mobile phones, computers and other electronic products growing in small, growing in fine, of which the development of molds play an important role.
We discuss the contents of the grinding process is to mold some of the latest developments. We Die Lapping as Tool Grinding, because the industry has used to this it is called.
Tool grinding mill with other difference is: completely by manual grinding machine, so the skill level operatives played a role of crucial importance. Among Grinding wheel Size selection, determine the degree of grinding wheel dressing, manual control of the amount of feed, etc., are determined empirically.
Tool grinding is generally divided into three categories, rough grinding, fine grinding and cleaning angle.
Coarse grain wheel usually use 46 #, largely to cut down the workpiece grinding to the required size, to achieve the required flatness and finish can be.
Grinding usually use 100 # or 120 # grinding wheel, in addition to grinding plane, sometimes until it has a certain groove. The shape of the grinding wheel has a higher retention requirements.
Clear angle about 320 # special wheel dressing to thin thickness, such as 0.02mm, and then cut out the slot, further trimming, the need to groove bottom diameter clear to R0.03mm
For rough grinding and fine grinding, grinding process has been basically standardized. But there is still need for new materials effectively in different types of grinding wheels. For example, the standard Die Materials To SKD11 and SKD61, with the cost reduction requirements, domestic materials gradually be adopted. Most commonly used is Cr12MoV and W6Mo5Cr4V2Al, when grinding these materials will find conventional domestic wheel loss will increase, it is because cutting and hardness of the material have changed, requiring a corresponding adjustment to the type and hardness of abrasive wheels to play a good grinding effect. If there is demand, you can contact the Norton grinding wheel to communicate professional and technical personnel, users will be tailored for different products suitable to improve efficiency and extend the grinding wheel life. Because the tool grinding wheel in addition to our common 38A white fused alumina series, there are single-crystal corundum family, and SG 32A ceramic corundum family, depending on the material, we will choose different abrasive grinding wheel. With a grinding wheel to all the materials are often not good results.
