Core Advantages of 3 Axis Aluminum Mold Milling Center for Rail Transit Industry:
SM series machine compatible with a wide range of materials, including cast steel, high-strength steel, and aluminum alloys, the SM series efficiently processes everything from precision components like axle boxes to long structural parts like body beams.
The SM series utilizes a closed-loop solution combining “hardware rigidity + software control + full-cycle calibration” to achieve stable precision with “no deformation under heavy loads, no vibration at high speeds, and no drift over time.” This meets the long-term demands for millimeter-level accuracy in automotive chassis and railway transit applications.
Features of 3 Axis Aluminum Mold Milling Center for Rail Transit Industry:
1. The machine body utilizes a seamless welding process and a high-density cast worktable, annealed at 800°C to eliminate internal stress and ensure a deformation rate of ≤0.001% after long-term use. The base and column utilize a mountain-shaped rib-reinforced design to minimize force flow. Combined with an extra-wide base and widened column bottom span, the machine’s center of gravity is lowered to an optimal stable height, resulting in a 40% increase in torsional strength compared to traditional structures.
2. Imported heavy-duty ball guides are standard on the X/Y/Z axes. The track surfaces undergo high-frequency quenching, resulting in a friction coefficient as low as 0.008 while ensuring rigid support. The lead screw utilizes a C3-grade ground nut drive mechanism with a pre-tension of 15% of the screw’s rated dynamic load, completely eliminating backlash. High-quality couplings ensure motor-screw coaxiality error of ≤0.002mm, resulting in a transmission efficiency exceeding 98%.
3. Stable Spindle Assemble Design: The contact length between the spindle and the plate is optimized to a 1:3 golden ratio, providing balanced support for the entire stroke. Adopt oil cooling system, with constant-temperature coolant circulation controlling internal spindle temperature fluctuations to within ±1°C, effectively minimizing accuracy deviations caused by thermal expansion.
4. Auto Lubrication and Maintenance Warning: Auto lubrication system, coupled with an on-board lubrication pump, ensures uniform lubrication of key components such as the guide rails and lead screw. Oil level and pressure monitoring provides automatic oil shortage alarms.
5. Flexible Chip Removal and Cleaning Design: The machine comes standard with a double-helical chip conveyor and a lifting chip conveyor (extended for heavy-duty operation), achieving a chip removal speed of 3m/min and handling chips up to 50mm in diameter.
6. The spindle nose is equipped with an air curtain dust control and a central air blower, with air pressure reaching 0.6MPa, effectively preventing chips and coolant from entering the spindle, extending bearing life by over 30%.
