When cutting soft metals like aluminium & brass, there is nothing easier to use and more suitable than a high grade 1 flute up cut. An 1 flute has the best chip ejection and heat dissipation which avoids jamming due to the gummy nature of soft materials. An 1 flute also has the capability to operate effectively with widely varied feeds and speeds as compared to 2 & 3 flute when slotting. For peripheral cutting, a 2 or 3 flute for soft metals is ideal for the side & bottom finish.
- Soft Metals (Aluminium & Brass)
- Plastics (ABS, acrylic, HPDE etc)
- Aluminium Composite Materials
You will get a different finish on the side of your material depending if you use a climb or conventional cut. Do some test cuts and check which side comes out the best and adjust your toolpath accordingly.
