A bout our Bits and Block Systems
Bits and Blocks have evolved over the last 50 years from stationary picks to sophisticated rotating systems transmitting 1000's of horsepower energy units into the cutting action. CP Carbide’s staff have worked in the field on the leading edge of technology and developments. Many of the concepts that are public domain today were developed by the engineers at CP Carbide. Some examples are the spin shield rotating
block protector, the flaired shank for the deflection of abrasion material, the octagonal tip for improving bit rotation, and the carbide ring system to stop shank wear. A bit is generally a complex 5 piece structured part. The tungsten carbide tip is the first surface to impact the cut material. It is held in place by a strong high temperature braze joint attached to an alloy steel shank. The alloy steel shank is hardened to retain shape under high forces. The bit is held in the block by a retention clip or sleeve system. The clips can be internal or external rings. Function of grade properties and geometry provide the wear characteristics of the systems. CP Carbide’s staff is trained to offer the best combination of bit and block for the desired application.
Useful Information about our Bits and Blocks
CP Carbide has developed specific grades that will enhance and offer long life performance of the bit. The balance of grain size and binder content gives the desired user results. New technologies, like binder wetting to the macro grain and HIP sintering have dramatically improved tool performance. You can choose from many geometric designs that will improve tool performance and tool life. The grade of steel in the bit provides the strength properties. Using high temperature braze alloy gives the user the most strength possible, while offering heat treating when the braze joint is formed. The holder or block should be made of a high strength alloy steel. Many of the block systems are welded directly to the machine drum or rotor so the steel properties of the holders should be weldable and also maintain high strength properties to hold them for long life on the drums. The holding systems should have as much wear protection as possible to avoid premature wear deterioration and failure. The ability to change the holding system in the field is important to reduce the cost and down time due to equipment changes.
