Selection of key durability technical parameters
1. Mechanical structure parameters
• Frame material: Prefer the integral cast iron or thick steel plate welded structure (thickness ≥ 20mm) and avoid lightweight aluminum frames
• Bearing Grade: Choose precision bearings from brands such as SKF/FAG P5 grade or above
• Rail Type: Linear rail is better than ordinary sliders, HIWIN or THK brands are recommended
2. Cutting system parameters
• Shaft material: 42CrMo alloy steel, hardness HRC52-55
• Blade life: Choose a coated blade (TiN/TiCN) with a lifespan of ≥ 800 hours
• Tool setting accuracy: repeat positioning accuracy ≤± 0.02mm
3. Drive system
• Servo motor: choose Yaskawa, Mitsubishi and other brands, overload capacity ≥ 300%
• Reducer: Planetary reducer is better than ordinary gear reduction, and Newsdale brand is recommended
• Transmission mode: Synchronous belt transmission noise< 65dB, the lifespan should ≥ 10,000 hours
Selection strategies to reduce maintenance costs
1. Modular design: choose a model that can be individually replaced (e.g. independent tool block module)
2. Lubrication-free components: Models with self-lubricating bearings and oil-free guides are preferred
3. Intelligent Diagnostic System: Choose a model equipped with vibration monitoring and wear warnings
4. Standardized accessories: Confirm that the equipment uses standard-sized bearings, belts, and other wearing parts
Cost-effective evaluation formula
Total equipment cost = purchase cost + ∑ (annual maintenance cost × service life)
It is recommended to choose the model with the lowest total cost and within the following parameters:
• Mean Time Between Failures (MTBF) ≥ 2000 hours
• Critical component design life ≥ 5 years
• The manufacturer provides a minimum 3-year warranty on core components
Through the above technical parameters, the maintenance cost of the whole life cycle of the slitting machine can be significantly reduced.
