As a small or medium-sized mold manufacturer, choosing the right CNC engraving and milling machine can make or break your production efficiency and product quality. When it comes to precision machining of aluminum molds or complex curved surfaces, understanding the crucial technical parameters of CNC machines is essential to avoid costly mistakes and downtime.
Your machining quality heavily depends on two fundamental accuracy metrics:
GB/T 18400.3, this is critical for consistent dimension control.For example, a positioning accuracy of ±0.01 mm and repeatability within ±0.005 mm are ideal benchmarks for high-precision aluminum mold processing. Machines with inferior parameters may cause dimensional deviations affecting mold fits and surface finishes.
The spindle speed range relates directly to the types of materials and finishes you can achieve. A wide adjustable range, such as 5000 to 24,000 RPM, allows you to optimize cutting conditions for aluminum and other soft metals while maintaining fine surface textures.
Equally important is the machine’s structural design. For molding applications demanding stability and precision, a gantry-style CNC engraving machine generally outperforms cantilever models, thanks to superior rigidity and vibration control.
| Feature | Gantry Structure | Cantilever Structure |
|---|---|---|
| Rigidity & Stability | High rigidity minimizes vibration during milling | Lower rigidity; vibration risk in heavy loads |
| Workpiece Size Handling | Supports larger and heavier molds | Limited workpiece size capacity |
| Maintenance & Accessibility | Easier maintenance due to balanced frame design | Potential accessibility challenges |
When working with aluminum molds, the worktable must support not only the raw material but also withstand forces from high-speed milling tools. Ideally, your machine’s worktable load capacity should exceed the maximum expected mold weight by 20-30% to ensure operational safety and reduce mechanical strain.
For example, if your typical mold weighs 100 kg, opt for a worktable rated for at least 120-130 kg load. This consideration directly influences machine longevity and machining accuracy during extended production runs.
