Free image of blade machining for a screw pump using a 5-axis CNC center and stainless steel disc material.
Due to the properties of stainless steel, precision machining requires careful attention to heat generation and tool wear. In this process, rather than using dull-angled throwaway inserts, a sharp end mill was selected to perform trochoidal (slice) cutting. This method helps minimize heat buildup during cutting.
For coolant, a highly penetrative and thermally efficient strong alkaline ionized water was used. This fluid offers several advantages:
- High pH (~12) prevents bacterial growth, reducing the risk of spoilage and extending fluid replacement cycles.
- Excellent penetration and cooling performance help reduce tool wear and allow for more aggressive cutting conditions.
- Superior cleaning ability makes it easy to remove chips and residual coolant from the workpiece and machine.
