DEK Automotive produces highly complex automotive CNC parts requiring simultaneous multi-axis coordination and precise tool orientation control. We machine EV structural frames, lightweight housings, aerodynamic components, and integrated assemblies where conventional machining cannot maintain geometric stability across multiple surfaces.
Tolerances listed here are minimums for an ideal case. Looser tolerances may be required depending on process, material choice, or part geometry. If you have no detailed requirements for product tolerance, we can follow the following general ISO2768 tolerance table.
| Standards | Metric Units |
|---|---|
| Maximum Part | 850 x 800 x 500 mm |
| Minimum Part | 4 x 4 x 4 mm |
| Minimum Feature Size | Φ 0.50 mm |
| Standard Tolerances | Metals: ISO 2768-f; Plastics: ISO 2768-m |
| Linear Dimension | +/- 0.02 mm |
| Hole Diameters (not reamed) | +/- 0.02 mm |
| Shaft Diameters | +/- 0.01 mm |
| Edge Condition | Note project requirement on drawings |
| Threads and Tapped Holes | 1.Standard size: Diameter: standard drill bit sizes; depth: 4×diameter 2.Maximum size: Diameter: Φ 1 mm; depth: 10×diameter 3.DEK can produce threads of any specification and size required by ourcustomers. |
| Text | 1. For plastic and soft materials: minimum width of 0.457 mm, depth of 0.3mm 2. For hard material: minimum width of 0.838 mm, depth of 0.3 mm 3. DEK can use CNC engraving or laser carving to create standard text based on customers’ requirements. |
| Lead Time | 8 business days for less than 50 parts |
