Drill lengthening connection

In production, the length of the drill bit is often used to solve the hole with a depth greater than the length of the drill bit or a hole that is not accessible to the deep drill bit. The key to the length of the drill bit is the way the drill bit is connected to the post. It not only ensures the coaxiality of the rod to the drill bit, but also connects reliably and transmits the cutting torque. To this end, we use the three lengths of the drill bit as shown in the figure, after many years of use, the effect is very good.

CBN Grinding Wheels

CBN is a man-made Superabrasive that outperforms Diamond when used for Ferrous grinding operations.

CBN derives its name from its chemical makeup, of the cubic form of boron nitride (CBN). It has a very desirable characteristic that is sought after when working with difficult to grind (DTG) materials.

Due to its high thermal stability and chemical resistance, the CBN grinding wheel is most suitable for grinding hard ferrous materials, hardened steel, bearing steel, nickel based alloys. machining ferrous materials.

CBN Grinding Wheels are used to sharpen, cut, or remove metal from hard surfaces. Use these wheels when you need a good consistent finish.

Most notably CBN wheels are used to cut HSS metals, like wood tools, blades, bits, and cutters. This type of steel is better than the older high-carbon steel because it can withstand higher temperatures. When you`re tools become dull over time from use, a CBN wheel will bring them back to its sharp use.

Kemei produce CBN(cubic boron nitride)grinding wheels, which can be resin bonded CBN wheel, metal bonded CBN wheels and electroplated Diamond Grinding Wheels. For same steel parts, you can choose all three types CBN wheels, but there still some difference, if you need more information and the best solutions ,please contact us.
