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.

Plastic machining refers to the machining of plastic blanks using processes such as turning, milling, drilling, thread cutting, knurling and grinding to produce various precise components. This process is used in numerous areas.
In mechanical engineering, plastic machining is often used to produce guide bushings, spring adjusters, sealing rings and rollers. These parts are often hidden inside machines and devices, but play a crucial role in their reliable operation.
In the medical sector, plastic machining is used to manufacture dental prostheses, such as dentures. Milling or polymerization processes can be used to produce high-strength dental materials that meet the strict requirements of medical applications.
Plastic machining also plays an important role in the processing of fiber-reinforced plastics. These materials, which are valued for their high strength and rigidity, are used in areas where lightweight yet robust materials are required. Machining processes can be used to further process these near-net-shape components, for example by milling grooves, drilling or circumferential milling of contours to meet specific design requirements.
It is important to note that the choice of tooling during the machining process depends on the type of plastic. For example, non-reinforced thermoplastics can be machined with high-speed steel tools, while fiber-reinforced materials require carbide tools, hard-coated tools or polycrystalline diamond (PCD) tools to cope with the abrasive nature of the material and ensure high machining quality.
