Application of C-type four-axis wire cutting machine tool in precision machining of subway station shield door drive components
"A delay of 0.1 seconds may cause safety hazards to millions of passengers" - In the field of urban rail transit, the reliability of the platform shield door system is directly related to the travel safety of tens of millions of passengers. When traditional processing methods are difficult to meet the stringent precision requirements of drive components, how can Zhikai CNC's C-type four-axis medium-speed wire cutting machine become the "invisible guard" of industry safety protection? This article will deeply analyze the processing pain points of key components such as subway station platform shield door drive components, and show how Zhikai has won the trust of the industry with innovative technology and perfect services.
Case customer product analysis: Processing challenges of subway station screen door drive components
The core component of a certain urban rail transit company, the subway station screen door drive assembly, needs to withstand tens of thousands of start-stop cycles per day. Its processing accuracy directly affects the system response speed and service life. The manufacturing of this component faces three core challenges:
1. Precision machining of complex spatial surfaces
The driving gear needs to be processed with involute curved surface and special-shaped groove, and the contour accuracy requirement is ≤±0.00 3 mm. Traditional processing is prone to produce cutting marks, resulting in a 30% increase in transmission noise.
Industry data: For every decrease in surface accuracy of ≤±0.00 3 mm, component life is reduced by approximately 20,000 cycles
2. High consistency of multi-angle inclined holes
The component needs to process multiple 30°-45° inclined lubrication holes, with a hole diameter tolerance of ≤±0.00 3 mm and a position requirement of ≤±0.00 6 mm. Ordinary machine tools are difficult to ensure batch consistency
3. Stable cutting of high hardness materials
Alloy steels such as 42CrMo (HRC48-52) are used, which are prone to surface microcracks during cutting, and the subsequent heat treatment deformation rate is as high as 15%.
Technological breakthrough of Zhikai C-type four-axis wire cutting machine tool
In response to the special needs of the rail transit field, Zhikai CNC's C-type four-axis medium-speed wire cutting machine tool has achieved technological breakthroughs through five major innovations:
1. Four-axis linkage space compensation technology
XYZC four-axis synchronous control, supports ±15° taper cutting, and the processing accuracy of complex curved surfaces is improved to ≤±0.00 3 mm
Customer test data: Drive gear noise dropped from 75dB to 62dB, life extended to 1.5 million cycles
2. Intelligent inclined hole processing system
Equipped with 3D spatial positioning module, it automatically calculates the optimal processing path, and the efficiency of inclined hole processing is increased by 40%.
3. Material adaptability enhancement plan
Adopting the "high frequency pulse + adaptive tension" combination technology, the cutting speed of high hardness materials reaches 25mm²/min, and there is no deterioration layer on the surface
4. Whole process quality monitoring system
Integrated online measurement system, real-time compensation of processing errors, batch production CPK value is stable above 1.67
5. Rail transit special process package
Built-in processing library for shield door components, shortening the introduction cycle of new projects by 60%
