How do I turn fibreglass?
For turning, we recommend using carbide plates with speeds of up to 400 m per minute. A top rake of 10–15° will yield the best results. The feed rate and cutting depth will depend on the machine used, but is typically between 0.05 and 0.5 mm/rev. Depending on the machine and the set-up, the depth of cut can be up to 10 mm. Using rounded tool bits and air or liquid cooling results in the best surface finish. Turning can also be done with a rotating diamond milling cutter in the tool holder.
