  • Moving speed, axes X is 26m/min, Y is 60m/mi, Z is ≥15m/mi. Proficient in spatial surface, irregular shape, hollow, punching, drilling, cutting, etc.
  • Mainly produce titanium metal or precision metal for electronics, automation, automobile, aviation, aerospace, military, scientific research, precision instruments, high-precision medical equipment, etc,
  •  Six-axis CNC.  It allows movement in six freedom directions, including three rotary and three linear axes. It has axes X, Y, Z, A, B, C, and mainly produces precision components for automotive, aerospace, and medical, etc.


Bevels.    Are sloping edges between two main surfaces on 2 precision products, that help improve wear resistance, safety and aesthetics, they can prevent sharp edges from injury. Our precision products have bevels to prevent our customers from scrape.

Chamfer.    it is always at 45° between two right-angled surfaces of the same part, it can remove sharp 90° edges from precision parts, and prevent injury during processing. Also protects the corners from damage, thereby improving the overall integrity. Also, our precision products have chamfer to avoid any potential damage.

In general, the surface is Ra0.8, which can see a polishing mark. inner wall is Ra0.2, which can’t see any polishing mark. Dark Gloss is Ra0.1, Glossy is Ra0.05, Mirror Gloss is Ra0.025, Matte Mirror is Ra0.012, Mirror is Ra0.006.


  • The ability to resist pressing a hard object into a precision product surface, the higher the hardness, the better the wear resistance.
  • Brinell hardness, is the ratio of load to indentation area, the load is press 3000kg onto precision products surface by a ball Φ10mm, it is suitable for HB >450kg/mm2.
  • Rockwell hardness.  When HB <450kg/mm2 or sample is very small, press a diamond cone with 120% angle onto precision products surface, 
  • pressing the 60kg load onto extremely hard tungsten carbide, we call it HRA,
  • pressing the 100kg load onto lower hardness annealed steel, cast iron, we call it HRB,
  • pressing the 150kg load onto very hard hardened steel, we call it HRC.
  • Vickers hardness. Press <120kg load onto precision components surface by a diamond cone with 136% angle.

Corrosion resistance

  • For example, BeCu hardness is 200~250HV before quench, will change to be ≥36-42HRC after quench,
  • Corrosion resistance speed of BeCu in seawater is (1.1~1.4)x10-2mm/year, Corrosion depth is  (10.9~13.8)x10-3mm/year,
  • There is no change in strength or elongation after corrosion,
  • So, BeCu can remain in seawater for over 40 years.


  • it refers to precision metal does not fail under multiple alternating loads.
  • Stress damage is from crack generation, then extension, fracture finally.
  • So, we always select the most appropriate materials first, reasonable mechanical design to avoid sudden changes in shape.
  • Smooth bevels or chamfers are required, and low overall surface roughness is required too.

Magnetic Density

  • Precision products will also affect the performance of some electronic products after assembly with N52 magnets.
  • So, it is necessary to effectively control magnetic density sometimes.
  • And, it is not an electromagnet or permanent magnet,
Precision parts_231700953_precision products
  • so, we often use specialized demagnetizing coatings or electroplating resins to complete what customer want.

Oxidation.  It converts precision products surface into a protective film, is to extend the life cycle and add various color. Appropriate materials include aluminum alloy, magnesium alloy, titanium alloy.


  •  It is to prevent precision metal oxidation, improve wear resistance, conductivity, reflectivity, corrosion resistance, and enhance aesthetics.
  • Appropriate materials include copper, brass, nickel, silver, gold, chromium, zinc, tin, etc.
Precision parts_231700991_Precision Products


  •  It can get various colors to maintain precision products' luster and enhance surface corrosion resistance, with little impact on precision metal accuracy.
  • The thickness of one side is about 10-25um.
