Carbide Burr With High Hardness, Wear Resistance, Strength
Carbide Burr Material, structure and geometry are the three factors that determine the cutting performance of the tool, in which the performance of the tool material plays a key role. The International Society for Production Engineering (CIRP) said in a study that "the cutting speed allowed is almost doubled every 10 years due to improved tool material." Tool material from the early 20th century high-speed steel, carbide development to the present high-performance ceramics, superhard materials,Carbide Burr heat temperature has been increased from 500 - 600 ℃ to 1200 ℃ above, allowing cutting speed has exceeded 1000m / Min, making the cutting productivity in less than 100 years to improve the 100 times. It can be said that the development of tool materials in fact reflects the history of the development of cutting technology.
Compared with cemented carbide, ceramic materials have higher hardness, red hardness and wear resistance. Therefore, the processing of steel, the durability of ceramic cutting tools for carbide cutting tools 10 - 20 times, the red hardness than carbide 6 - 6 times, and chemical stability, antioxidant capacity are better than hard Qualitative alloy. The disadvantage of ceramic materials is brittle, transverse fracture strength is low, bear the impact load capacity is poor, which is in recent decades people continue to improve its focus.
Ceramic tool materials can be divided into three categories: ① alumina-based ceramics. In addition, TiC, WC, ZiC, TaC, ZrO2 and other components are added to the Al2O3 matrix material, and the hardness is up to 93 to 95 HRC by hot pressing. To improve the toughness, a small amount of Co, Ni and other metals The ② silicon nitride ceramic. Commonly used silicon nitride ceramic for the Si3N4 + TiC + Co composite ceramic,Carbide Burr its toughness is higher than the alumina-based ceramics, hardness is equivalent. ③ silicon nitride - alumina composite ceramic. Also known as Sialon (Sialon) ceramics, the chemical composition of 77% Si3N4 +13% Al2O3, hardness up to 1800HV, bending strength up to 1.20GPa, the most suitable for cutting high temperature alloys and cast iron.
Brush deburring is a process that removes the burrs on the surface of the workpiece by utilizing the brushing force to produce a cutting force with the workpiece instantaneous friction. Surface of the convex surface within 100mm of the workpiece, the workpiece on the existence of the hole,Carbide Burr the hole, the edge of the step, around the surface can use the brush to deburring machine to remove the workpiece burr. According to the workpiece material is different, choose a different brush to come glitches.
Carbide is a refractory metal hard compounds and bonded metal through powder metallurgy made of an alloy material. With high hardness, wear resistance, Carbide Burr strength and toughness is good, heat, corrosion and a series of excellent performance, especially its high hardness and wear resistance, even at 500 ℃ temperature is also basically unchanged at 1000 ℃ still have a high hardness.
Therefore, carbide corners passivation processing, the need to use the Swiss BP-MX corner passivation polishing brush to deburring machine, the machine can not only be used for carbide processing, but also on the ceramic and PCD and PCBN tools and Cutting tool polishing, corner passivation, deburring processing. By changing the table or clamping method, both on the plane plate class workpiece, but also on the shaft parts corner passivation polishing to deburring processing.
The plane or slightly convex workpiece is mounted on the planetary polishing table and is machined evenly with abrasive brushes. Through the table,Carbide Burr the workpiece carrier and brush the rotation of the workpiece in all directions of the corners have been a uniform passivation and remove the burr. The upper surface of the workpiece is also polished in this process.
The modular design allows for a special combination to suit the customer's application; the compound replaceable table has the greatest flexibility; can be dry or wet processed; the automatic compensation for the brush wear results in consistency of the results; Edge geometry; fully enclosed working environment; touch screen simple operation interface.
