Machining Thermoplastics: C6 End Mills for the Perfect Finish
Whether you’re a long-time metalworking machinist looking into machining plastics, or a maybe you have been working with plastics for awhile and simply can’t find the secret to achieving consistent performance; the key to plastic machining is trial and error.
Just because your equipment and machining techniques are easily adaptive to machining plastic stock, According to the Larry Phippen, owner of Adapt Plastics in Loves Park, Ill., (www.adaptplastics.com) you’ll find that machining plastics require experimentation between different materials, different feed rates, and even different seasons.
“Most plastics have a high coefficient of thermal expansion and if your shop is not airconditioned a plastic will not cut the same way in summer that it does in winter. The data sheets usually have information on machining and that’s a good place to start, but the best way to really learn the material is to use it and experiment with it.” said Phippen.
Ultimately, it’s up to every individual operator to find what works for their machine depending on the job they are doing. So don’t be afraid of scrap, achieving perfect surface finish will require finding a perfect marriage between machine, material and cutting tool.
Rigidity is the Key to Plastics Machining
Metal’s natural rigidity makes it an ideal material for machining in high speed and high temperature environments. In the case of plastics, finding the right material for your machine and environment can be confusing.
When choosing your material, high rigidity in plastics such as fibre reinforced thermosetting plastics, glass reinforced nylons, acrylic or PEEK have good relative stiffness.

C6 has designed a line of millings cutter specifically for machining thermoplastics.
Experimentation is required to find the proper machining parameters for your job. So test different plastics with your specific machine, with different speeds and feeds in order to find your desired result.
Ultimately, achieving high quality surface finishes relies on using the best cutting tool for the specific part. When looking for the right cutting tool there are a few things to consider, including: tool geometry, tool material, and number of flutes.
C6 end mills exclusively for thermoplastics feature all you see below to help you achieve the unparalleled finish quality.
Ultra-sharp cutting edges produce crystal-clear finishes.
Over-sized flutes improve chip evacuation for the high material removal rates associated with plastics.
Highly-polished flutes and flanks aid chip transport and improve surface finishes.
Special grade, very hard carbide maintains sharp edges longer.
