Carbide Rotary Burrs The Small Size Tool Created The Big Revolution The appearance of rotary burr has changed the processing mode of hand filing in the past. The efficiency of machining has been greatly improved. The application of rotary burr is wide. Basically, it can replace small wheel with handle and no dust pollution. Carbide rotary burr with long service life. The durability is ten times higher than the high speed steel tool, and more than 200 times higher than that of the small grinding wheel. The cost of integrated processing can be reduced dozens of times. The carbide rotary burr is playing a great role
Carbide Inserts are widely used to process steel, stainless steel, cast iron, aluminum, copper etc for automobile, aircraft, shipping, mold enterprises. With high efficiency and stronger wear-resistance, working efficiency could be at least 4 times than traditional welding inserts. Technological advance of PVD and CVD coating will update the life time of carbide inserts. We follow regular 5 kinds of coating, TiN, TiCN, TiAlN/AlTiN, AlCrN, Diamond. Also we design our own groove to increase chip removal and heat dissipation. Superhard material PCD and CBN is also our cares. This kind of inserts have special property compared with carbide inserts. Please visit our products to know more.
Gun drills and BTA are made by tungsten carbide in Japan, UK, Germany at 60’s in 19 century, but China brought in it on 80’s in 19 century. That is more than 20 years late than western countries. Until now, 90% deep hole drilling equipment are imported from other countries. With the economic growth, deep hole drilling system plays a more and more important role in the automotive, aerospace, energy, oil and gas exploration. Deep hole drilling system are consist of workpiece, cutting tools, special assistive device, machine and control system. The biggest difference between deep hole drilling machine and general-purpose machine is that, operator cannot see the drilling process directly by vision. It is difficult to know the situation of chip-breaking, chip-removal, chip-shape, cutting-edge wearing, the surface of workpiece and drills moving direction etc. However, these factors will decide the processing result good or not. So, the difficulty of deep hole drilling technology is beyond general-purpose cutting process.
