Brief introduction of ZZbetter PDC cutters

PDC cutters are also named Polycrystalline Diamond Compact cutters, PDC bits, PDC inserts. PDC cutter is a kind of superhard material.

The Production of PDC Cutter
The PDC cutters consist of a Polycrystalline Diamond layer and carbide substrate. The diamond layer and substrate are sintered under ultra-high pressure and ultra-high temperature. In short, we say it’s HTHP Press.
The diamond is grown on the carbide substrate, not coated. They are firmly combined.

The applications of PDC cutters
ZZbetter PDC cutters are produced with high-quality man-made diamond powder and tungsten carbide powder. The PDC cutters combine the high hardness and abrasion resistance of diamond and tungsten carbide, which are widely used for different drilling tools such as mining bits, geological bits, diamond DTH bit, diamond pick, and other drilling tools. The PDC cutters are used in nearly all applications including geothermal energy drilling, mining, water well, natural gas drilling, and oil well drilling.

Brief introduction of ZZbetter PDC cutters

The advantages of PDC cutters.

Compared with traditional tungsten carbide buttons, PDC cutters have the following advantages:

1.     The working life of the PDC cutters is increased by more than 6 times

2.     The production efficiency is increased by more than 20%.

3.     Make the target for one time completed drilling become possible

4.     Reduce the frequency of replacement of drilling bits and the labor intensity of workers.

 

The shape of the PDC Cutter

  1. Flat PDC cutter

  2. Spherical PDC button

  3. Parabolic PDC button,      front button

  4. Conical PDC button

  5. Square PDC cutters

  6. Irregular PDC cutters

     

    The characters of PDC cutters

    1. HTHP press (high temperature and high pressure)
    2. Diamond thickness 2mm
    3. High impact resistance, excellent abrasive resistance.
     combines the advantages of both diamond and tungsten carbide.

    The quality control of ZZbetter PDC cutter
    Zhuzhou better tungsten carbide company deeply understands that the quality is the life of any product, is key for any industrial. To ensure every piece of PDC cutter comes to ZZbetter customer’s hands with high quality,ZZbetter has established a strict quality control system, including raw material control, production process control, first piece control, and finished products control. ZZbetter has got the ISO9001:2015 certificate. We strictly carry on ISO9001:2015 requirements to guarantee quality.

    1. Raw material control:  both for man-made diamond powder and tungsten carbide material( WC-Co)

    2. Production process control: check the temperature and pressure in real-time and adjust in time

    3. First piece control of PDC cutter

    For every batch of PDC cutters, the first piece is very important. By inspecting the first piece of every batch, we can confirm whether it meets the customer's requirements for dimension and performance.

    We always inspect the first piece of PDC cutter from below following aspects

    1)      Appearance: Whether the diamond layer is defective

    2)      Dimension

    3)      Impact test for PDC cutters and abrasion resistance test for PDC buttons.

     

    1.     Finished products control

    1)      Appearance

    2)      Dimension

    3)      Performance: abrasion and impact test


    After finishing the production of PDC cutters, we will do sample testing randomly.

     Due to the advancement of equipment, the increasing of construction requirements, and the increasing construction difficulty, the traditional drilling bits with tungsten carbide buttons cannot meet the market demands. Thus the drilling bits with PDC cutters have emerged.
