What is Worm
This equipment is designed for small modulus precision worms (such as automobile wiper shaft worms), planetary screws, trapezoidal threads and other workpieces. This type of workpiece is the core component of automobile transmission and precision machinery, the commonly used material is HRC58-62 hard alloy, and the geometric characteristics are high tooth shape accuracy requirements (±0.01mm), and the surface finish directly affects the transmission noise and life. Traditional processing is prone to risks such as tooth shape error, insufficient finish, and low efficiency.
High Precision Whirling Core Pain Point
There are three major bottlenecks in the milling of traditional vertical machining centers: (1) low efficiency: a single piece takes more than 3 minutes, which cannot meet mass production; (2) Poor quality: Ra ≥ 1.6μm, resulting in high transmission noise and fast wear; (3) High cost: 1 unit per person, labor accounts for 35%, and the scrap rate increases the loss by more than 3%.
High Precision Whirling Process
Blank → cyclone milling and milling machining→ surface treatment→ inspection:
- Blank: HRC58-62 hard alloy bar, hydraulic chuck precise clamping;
- Cyclone milling and milling processing: Cyclone milling head rotates at high speed (2000-5000r/min) to quickly remove allowance; After one processing, the full closed-loop grating system controls the C-axis direct drive motor to ensure that the tooth shape accuracy ± 0.01mm;
- Surface treatment: cooling system + 30μm filter to maintain Ra≤0.3μm;
- Inspection: Measure tooth shape error and roughness online, and control quality in a closed loop.
Key points of the sub-link
- Blade root/tooth shape: five-axis linkage tool path with S42 hydraulic chuck to reduce clamping error;
- Profile/Pneumatic: The cyclone milling head adopts FAG/SKF bearing, stable operation without vibration;
- Cooling hole: suitable for thread processing scenarios, cooling system dual motor + oil temperature machine temperature control;
MX500-N50 External Screw Whirling Machine
MX500-N50 precision cyclone milling is a special machining machine tool for small modulus precision worm, planetary screw, trapezoidal thread and other parts. Adopting full closed-loop control technology, it can process HRC60±2 degree hard materials, with a surface roughness of Ra 0.3μm or less, and the pitch accuracy meets the JIS B1192-C5/GB/T17587.3-P5 standard. The equipment has strong stability, simple operation, and supports the production mode of one person and multiple machines, effectively reducing labor costs and production cycles.
