Precison CNC Machining
Material:Aluminum,Stainless Steel,Copper,Brass,POM,Plastic,Ceramic etc
Certificate:ISO9001 & 16949
Inspecting: Carl Zeiss/Hexagon CMM
Machining center: 3-4-5 Axis Machining center, Mazak,Hass,and brothers brand

1. Basic parameters of the equipment
Processing stroke: The X-axis stroke can reach 200 millimeters, and the distance from the spindle nose to the worktable is 100 millimeters.
Main spindle power: Common configurations include 15 kW and 22 kW, and the appropriate power should be selected according to the material hardness.
Whole machine structure: Some models are made of 304 stainless steel and equipped with guide rails, footrests, and pressure blocks to enhance rigidity.
2. Processing technology and tool selection
Process classification: divided into rough cutting (fast material removal with large cutting tools), medium/semi finishing (transitional processing), and finishing (small step high speed).
Tool matching:
Plastic/Wood: Domestic white steel knife;
Copper aluminum/low hardness steel: imported or high-quality domestic steel knives;
High hardness mold steel: alloy knife, titanium plated knife or tungsten steel knife 2
3. Cutting parameter settings
Speed and feed: It needs to be adjusted according to the hardness of the material and the type of tool. During precision machining, high speed is required with a small cutting step of 23.
Thermal stability impact: Insufficient preheating of the machine tool may lead to dimensional fluctuations (such as early processing errors of 5-6 threads), and it is necessary to stabilize the accuracy through a thermal machine.
4. Control system and operation
Program transfer: Supports transferring G-code from a USB flash drive, and the operation process includes standardized steps such as tool alignment and startup.
Emergency stop and limit: The external button can be configured with emergency stop, jog, and high/low speed switching functions. The limit signal needs to be designed to be normally closed to ensure safety.

1. Medical device manufacturing
Implants and prostheses: such as hip/knee implants, bone nails, bone plates, etc., must meet 4 μ m tolerance and biocompatibility requirements (titanium alloy, PEEK material).
Surgical tools: Minimally invasive surgical instruments, robotic arm components, etc., rely on five axis machining to achieve complex geometric structures.
Medical equipment: endoscopic catheters, electronic medical equipment casings, and precision components.
2. Aerospace
Used for machining complex rotating parts such as turbine shafts and fuselage structural components of aircraft engines, requiring micrometer level precision.
The five axis machining center can handle deep cavity parts and meet the requirements of high-strength materials (such as 7075-T6 aluminum alloy).
3. Automotive industry
New energy vehicle parts, chassis, and high stress components are produced through CNC for rapid prototyping and flexible manufacturing.
Integrating digital manufacturing technology into smart factories to improve processing efficiency
4. Precision Electronics and Optics
Mobile phone/computer casings and optical instrument components rely on high surface smoothness and dimensional stability.
Supporting five axis drilling and attacking center in the 3C industry, optimizing AI technology.
5. Other fields
Mold manufacturing: precision machining of injection mold cores and cavities.
Customized products: such as prosthetics and dental instruments, personalized production is achieved through 3D scanning and CAD modeling.
