Use 3D software to establish product models, accurately communicate the processing program to the computer, through the cooperation of advanced 3,4,5 axis processing equipment, your products have been running on professional CNC production lines, holes, threads, dimensional tolerances, etc. Under our control.
The precision CNC machining center is a high-efficiency and high-precision automatic machining process developed by modern industry according to the traditional milling machine. It uses data and software to control the cutting of tools and parts with mobile processing. It has many varieties of products, complex structure, precision and efficiency Low advantage.
01.
annealing
This is a metal heat treatment process that slowly heats the metal to a certain temperature and keeps it for a sufficient time and then cools it at an appropriate speed to reduce the hardness and improve the machinability, reduce residual stress, stabilize the size and reduce deformation. Refine material grains and eliminate organizational defects.
- Reduce Hardness
- Improve Machinability,
- Reduce Residual Stress,
- Stabilize Size
- Reduce Deformation.
- Eliminate Organizational Defects.
02.
carburizing
The heat treatment process that acts on the metal surface is widely used in low-carbon steel and low-alloy steel. As for the activated carburizing medium, it is heated to 900-950°C to obtain a high-carbon surface after heat preservation.
- Improve surface hardness
- Improve material wear resistance
- Improve material fatigue strength
- Keep low carbon steel strong and tough
03.
Vacuum hardening
The metal material is smoothly quenched with less than one atmosphere pressure in the vacuum furnace, and filled with high-purity neutral gas, water, oil, and other media. Used in various carburizing steel, alloy steel, stainless steel, etc.
- Small deformation
- High efficiency quenching process
- Energy saving
- Low pollution quenching process
- Surface activation and clean
04.
Nitriding
At a certain temperature, the chemical heat treatment process in which nitrogen atoms infiltrate the surface of the workpiece in a certain medium can be divided into: liquid nitriding, gas nitriding, ion nitriding, and nitrocarburizing.
- High hardness and high wear resistance
- High fatigue strength
- High seizure resistance
- High corrosion resistance
- The deformation is small, regular deformation and controllable.
05.
Induction hardening
Induction current is generated on the surface of metal parts, which rapidly heats the surface of the parts and quenches them quickly. Generally, a hollow copper tube coil of intermediate frequency or high frequency alternating current is used to generate an alternating magnetic field and heat it quickly. The temperature can reach 800-1000°C in a few seconds to change the surface hardness of metal parts.
- Fast heating speed and high efficiency
- Low brittleness and high fatigue
- Not easy to oxidize
- Deeper hardened layer
