Company Profile
Company Introduction
Luoyang Qiming Superhard Material Co., Ltd was found in 1999, which ever belonged to CRRC Corporation Limited. The Company mainly focuses on R&D, produce and sell synthetic diamond and cubic press. In 2008, Qiming Company takes about 20 years’ experience for synthetic diamond and the geographical advantage, its main business change from synthetic diamond direction to high-end equipment manufacturing.
At present, the most advanced intelligent series cubic press series machines of Qiming have been widely used at home and abroad, and enjoy a solid reputation among the customers.
Product Description
The cubic press machine is the superhigh pressure machine for synthetic of superhard material, the press is mainly use in superhard material industry for producing and R&D of synthetic diamond, CBN, monocrystalline, polycrystalline, PDC, PCBN and other superhard material., Qiming hydraulic cubic press is safety, stable, easy operate and maintenance, high economic profile.

Products Application
Jewelry diamond.
There are more and more jewelry level synthetic diamonds produced now. With the synthetic technique progress the quality of diamond is getting better and better.
PCD
PCDs are widely used in oil and gas drills as no other material is capable of handling the extreme conditions. Large economic benefits are gained by rig drilling operators due to the use of these diamonds
PCBN and tools.
The full name of PCBN is "Polycrastalline Cubic Boron Nitride". Normally it is apply to superhard cutting tool and punching hole drill etc.
Our Advantages
Host Machine
1. The key component of the cubic press, hinge beam adopts Qiming's patented materials, and its performance is improved by nearly 30%, which guarantees the overall rigidity and stability of the equipment.
2. The combination of holder and anvil adopts a reverse angle design to balance the pre-tightening force. After a long time practical application test, the service life of the anvil and holder is extended.3. The cubic press adopts the integrated working cylinder structure and the design idea of large arc and small clearance fit. The pressure of the whole machine is evenly transmitted, which effectively avoids excessive local stress and reduces the failure rate.
4. The first introduction of the concept of silent press, there is no noise in operation, and the overall rigidity of the press is greatly improved, providing a more stable synthesis environment and ensuring synthesis safety.5. The key mating surface inside the cubic press adopts mirror processing technology to reduce the friction coefficient, improve the material density and wear resistance of the key mating surface, improve the synchronization and stability of the press, and improve the use of key components of the equipment service life
Electric and Hydraulic system
1. Proposing new concept of filling liquid, which means reasonably distribute function of each pump. It can achieve more stable formation process of synthetic cube sealing edge and extend the pump’s service life.
2. High-precision pressure control, the overpressure accuracy can reach 0.05MPa, the holding pressure accuracy can reach 0.02MPa, and the pressure relief accuracy can reach 0.02MPa.3. Large overpressure rate range, can achieve any overpressure speed less than the maximum overpressure speed, realize fast and slow overpressure, in actual use test 2 hours increase 1Mpa is normal (smaller overpressure speed has not been tested) .
4. The customized servo superhigh pressure pump set is adopted, with high starting response, small impact on the grid, constant torque output, power factor can reach more than 95% (ordinary motor power factor is only 83%), and the noise is less than 60dB. Provide a basic guarantee for the stability of the super-long process.5. Heating can be control by voltage, power, and current. Accuracy is 1mv, 1A, 1W.
Service Advantage
We are the manufacturer of HPHT since 1999, and have exported to more than 20 countries. So we can control a lot of aspects during the whole process, from casting, forging, machining to package, technical communication and after service. As you know the powerful after service is extremely important for foreign customer.

FAQ
1. What does this machine do?
This is HPHT cubic press, which is mainly used to produce and R&D synthetic diamond, CBN, PCD, PDC,PCBN,polycrystalline, monocrystalline, diamond repair, color alteration and other material.
2. Does this machine can produce CVD diamond?
Our press can produce the seed of CVD diamond, which is yellow single crystal diamond. But it cannot produce CVD diamondsdirectly. Synthetic diamond is also widely known as HPHT diamond or CVD diamond after the two common production methods (referring to the high-pressure high-temperature and chemical vapor deposition crystal formation methods, respectively).
3. Can this machine do diamond color enhancement?
Yes, it can. We have customers made it with our press by their own technology, which has made achievement.
