PDC Cutter for cutting marble is more efficient

Now there are two forms of marble mining: diamond wire saw and diamond chain saw. The diamond wire saw process uses wires of different diameters and lengths, which are full of diamond powder of various sizes to cut materials. However, the diamond wire saw is not strong enough, and it is easy to jam and break the rope. After several cuttings, the wire cutting efficiency of the diamond wire saw will be significantly reduced, and the production time is unpredictable.

More companies currently choose professional diamonds. The chain saw machine mines marble, and the diamond chain saw machine can be used for open-pit mining, or cave mining, horizontal cutting or vertical cutting.

Halnn PDC cutter is a tool specially used for mining marble with diamond chain saw equipment. It is also known as a diamond blade and a diamond chain saw blade. PDC is a polycrystalline diamond composite chip, a kind of produced polycrystalline diamond uses cemented carbide as the substrate. There are four types of structures: round and round with shank, square and square with shank for customers to choose.

Superhard CBN Tools Machining Bearing

Advantages of Halnn Tools Machining Bearings

1) Excellent both abrasion resistance and impact resistance;

2) High cutting efficiency and long tool life;

3) Patented product, non-metal adhesive CBN inserts.

Wind power bearings are difficult to machining after heat-treated. with the development of the modern Inserts industry, CBN Inserts is accepted by more and more customers. The last processing step of processing of wind power bearing processing uses BN-H200 Grade, which not only improves the processing efficiency but also reduces the processing cost.

When machining the outer ring of a wind turbine bearing, intermittent cuts are formed due to oil holes in the moon groove of the outer ring raceway, and the machining allowance at the moon groove is higher than the machining allowance of the raceway and the inner hole flange Therefore, the machining performance of the CBN Inserts is more important.

For wind power bearings, the accuracy tolerance of the raceway radian is 0.08, and the surface roughness of the raceway is Ra0.4

Superhard Tools machining High Hardness Mill

Mill Rolls are Important Tools and Key Components for Rolling Ferrous Metal Materials. the Cost of Mill Rolls is about 5%~15% of the Rolling Steel Production, Which is Directly Related to the Production Efficiency, Product Quality and Production Cost of the Steel Enterprises. Mill Rolls mainly can be divided into High hardness Casting Rolls, High hardness High Speed Rolls and Tungsten Carbide Rolls.

All of them have High Hardness and Large Allowance, and are difficult To Process. Especially for the Large Casting Rolls with the Casting Defects such As Sand, Stomata and Hard Spot , It will required the high hardness of Cutting Tools.

For all the above Process Conditions, halnn recommends Solid CBN inserts (RCGX, RNMN, CNMN), PCD Tools(PCD Notching Tools, PCD Engraving Tools), Carbide and CBN Notching Tools, and Arbor, Block and so on..
