High Speed Spindle
High speed machining with small tools requires high speed spindles because high RPM can reduce the chip load to less than 0.005”. Such a low chip load significantly reduces the forces between the tool and the material. High-speed, low-force machining yields less heat, reduces tool deflection, and allows machining of thinner walled work pieces. This all results in cooler machining, superior surface and edge quality, better accuracy and, as a by-product (of low force), easier workholding — since modular vacuum tables can be employed for quick set up and job changeover (particularly with thin flat substrates).
All DATRON high speed CNC machining centers feature high-frequency (HF) spindles with spindle speeds up to 60,000 RPM.
