Thermoplastics are polymers - i.e. plastics that are deformable when they reach a certain temperature. During production, the polymers are softened by heating, the heated material is molded and cools and hardens in the final material form.

A very well-known thermoplastic is acrylic PMMA, better known in the trade as Plexiglas and one of the oldest thermoplastics. The acrylic glass is particularly stable, hard and UV-resistant.

Thermoplastics are produced by various processes such as injection molding, compression molding, extrusion, blow molding, vacuum deep drawing, etc.

The finished thermoplastic can be further processed mechanically and thermally in industry. In this process, thermoplastic materials are processed by sawing, milling, grinding, turning, planing, bonding and welding.

When machining thermoplastics and acrylics, a specially developed tool design is required due to the low melting temperature of the plastic. This must be optimally matched to the carbide grade, cutting edge geometry and chip guidance. In the design of thermoplastic tools, the highest goal is to achieve a "clear cut", as this is important visually, especially with transparent thermoplastics.
The tools offered below for thermoplastics and acrylics achieve these quality requirements.

93103 HW 04

Technical details
Single tooth solid carbide router cutters made of either standard (HW 04) or micro-grain carbide (HW 08), with special cutting edge geometry for the best surface quality. With polished flutes and also with polished clearance for optimum chip removal and superior cutting results. Right-hand rotation - up-cut.

Application
For polish cutting (clearcut milling, grooving, sizing and severing) of thermoplastics e.g. PMMA (acrylic glass), PC (polycarbonate), PE (polyethylene), PP (polypropylene), PS (polystyrene), ABS (acrylonitrile-butadiene-styrene) and PVC (polyvinyl chloride). Nearly clearcut surface of the machined edges through pre-cutting against feed and
then finish-cutting (with low chip removal) with feed.

Application data:
Pre-cutting against feed: R.P.M. = 18 000 - 24 000, feed rate vf = 2 - 6 m/min.

Finish-cutting with feed: R.P.M. = 18 000 - 24 000, feed rate vf = 0,1 - 0,4 m/min., lateral adjustement ae = 0,1 mm - 0,3 mm

To avoid heat development resp. stress whitening, we recommend to support the chip removal through compressed air.
