CBN insert for machining brake drum with gray cast iron mate
Brake disc and brake drum is a typical auto parts, generally made of gray cast iron, commonly made of FC250 gray cast iron material, gray cast iron common material grades include FC250,FC200, etc. We can provide you solutions with tools on turning Gray cast iron.
BN-S30 solid cbn insert is researched specific for processing the gray cast iron, mainly for the automotive industry, such as brake discs, brake drum, Cylinder block, cylinder head, gear box shell, etc. Most of these parts are made of gray cast iron, ductile iron. BN-S30 solid cbn insert is special for this industry, in the processing of such materials of the work piece, BN-S30 solid cbn insert is a good choice.
When Finish machining brake discs, the surface roughness and shape and position tolerance is the basic guarantee of processing quality; and processing efficiency also determines the competitiveness of the auto parts industry. BN-S30 Solid CBN Insert in the processing disc shape and position tolerance (parallelism, flatness) and roughness, processing brightness has achieved very good results, and the processing efficiency of the brake disc to be multiplied. Halnn will share you how to use the insert combination to improve the processing of the brake disc.
Part 1 From blade to tool optimization
Halnn BN-S30 solid cbn insert machining FC200 and FC250 material brake discs and brake drum, can greatly improve the processing surface quality, while using a high linear speed, improving the processing efficiency more than 2 times. BN-S30 can get a good surface finish and brightness in the field of cast iron process, to solve a lot of auto parts industry defective high rate problems.
Part 2 Lifting beyond blade performance-Combining tools
The above success benefit from the emergence of high hardness and wear-resistant blade grades, and based on the handle (Arbor) to improve the combination of tool, making the processing efficiency will scale new heights, but also verify the mechanical processing industry, a word "Tool change process." The following is Halnn machining brake disc and brake drum industry for the design of the two combinations of tools, the blade is still using BN-S30 high wear-resistant CBN Insert, and Arbor is a combination of a variety of processing technology to optimize the design of the combined system, simple and practical.

Part 4 Machining brake disc
BN-S30 use ultra-fine grain, in addition to a good finish, this grade use non-metallic adhesive grade, to avoid the metal bonding agent to reduce the life of the blade, blade Durability increases, making the cost of cutting tools, while reducing the frequency of tool changes, processing efficiency has been greatly improved.
Before choosing the CBN Insert, the most suitable insert will be very important, if you want improve the processing efficiency and reduce processing costs, before buying the tool, good communication is necessary. Halnn CBN Insert provide comprehensive pre-sale advisory services and after-sale technical service.
Halnn Superhard is the predecessor of Henan Institute of Superhard Materials, is a professional production of cubic boron nitride tool of high-tech enterprises in the industry for the first gray cast iron, all kinds of wear-resistant cast iron / cast steel, quenched steel and other materials for tool development . The main products of welding composite cubic boron nitride tool and the overall cubic boron nitride polycrystalline blade, access to a number of practical patents, especially in the intermittent cutting hardened steel, high chromium white cast iron processing, and many other areas, leading the world-class level!
