Machining Polypropylene on the CNC Without Melting Cutting polypropylene and similar soft plastics on the CNC is tricky. To avoid melting the plastic, you need the right bits, RPM, and feed speeds. Here is more info. November 29, 2014

What is Climb Milling vs Conventional Milling (Down Milling vs Up Milling)? While many CNC'ers have gotten in the habit of always specifying climb milling, there are times to climb mill and there are times where conventional milling is preferred. Before we get into when to use each, let's have a quick definition of the differences.

May 11, 2009· Many plastics with added flame retardants contain halogen compounds. The most common are PBB's and PBDE's which are restricted by the RoHS directive. In the US many flame retardant plastics still contain PBB's or PBDE's; however, in Europe, where RoHS originated, I am sure they must have some new flame retardants for plastics.

Plastic's flatness stability is substantially lower than metals. Consider the following to improve. Balanced design. Dish shaped plastic machined components are notoriously difficult to avoid warpage..003" per a 4" square, unrestrained, is typical. Tighter tolerances require better fixturing and more machining.

CNC machining or routing is the cutting, shaping, drilling, milling, and surfacing of materials using a computer controlled router or milling machine. Plastic can be cut, shaped, moulded with patterned router cutters, drilled, surfaced, contoured etc.

Adapt Plastics offers CNC turning, milling and routing services for machining prototype, custom, lowvolume and small run plasticbased parts. We machine PET, PVDF, polyester and a variety of plasticbased materials, used in a wide range of industries with specialized plasticbased material and machining needs.

machining plastics, quick adjustments must be made to accommodate substantial creep — not to mention that the material has a strong propensity for chipping and melting during machining. Simply stated, the basic principles of machining metals do not apply when machining plastics. Machining Plastic has Unique Challenges ... and Rewards
