Polymers are extremely flexible in their technical properties and are therefore usable for a wide variety of applications in practically every sector.  Moulded parts, packaging materials or enclosures in automotive engineering are only a few examples for the further processing of plastics.

  • Polymers in general

    Milling polymers

    The milling of polymers involves some special features.  Compared to metals, plastics exhibit a much lower thermal conductivity.  Therefore, the heat created during the machining process must be evacuated via the chip.  For this task, HUFSCHMIED provides milling cutters that are perfectly matched to the respective material and that guarantee high feed rates together with an optimal surface quality.

    • The perfect milling cutter, specific for every material

      Our range comprises HSC milling cutters, torus cutters, thread cutters, disc cutters, plunge drilling cutters and shank cutters.  For every machining task there is the perfect material-related HUFSCHMIED tool that achieves the highest possible efficiency in machining without the need for post-processing.

  • Thermoplastics

    Milling thermoplastics

    Thermoplastics are polymers that, after heating and cooling return to their original shape.  Due to their many advantages, thermoplastics are amongst the most successful of polymers.  They are just as much at home in everyday applications as they are in highly specialised domains.  In lightweight construction, especially, thermoplastics are indispensable.

    A decisive factor in the processing of these materials is to keep the machining temperature to a minimum, otherwise the material could overheat, soften and deform. It may then not be possible to return it to its original shape.

    • High feed rates and clean-cut edges without burr formation

      With tools from the Universal-Line and the Sharp-line, HUFSCHMIED offers the optimum conditions for the milling of thermoplastics.  Depending on the requirement specification and machinery, one-, two- and three flute tools can be involved.  This also applies to torus cutters, shank cutters and radius cutters.

      With thermoplastics, the main aim is to produce a burr-free, high-quality cut edge at high feed rates.  Hufschmied tools from the Universal-Line and Sharp-Line are perfectly matched to meet these requirements and guarantee a processing quality without the need for post-processing.

  • Elastomers

    Milling elastomers

    Elastomers are plastics that are remarkable for their elasticity.  Their glass transition point is below their operating temperature.  Therefore, they retain their shape, but can undergo elastic deformation under stress and return to their original shape after deformation.

    Among the elastomer group are synthetic rubber, latex or natural rubber.  Their machining is very challenging in respect to both surface quality and edge-retention quality for the tools in use.  Tools from the Sharp-Line are perfectly suited to meet the requirements for the drilling and milling of elastomers.  Tools from the Universal-Line are suited to the machining of hard rubber.

    • Minimal deformation and no gumming-up

      Sharp blades of the Sharp-Line tools exert a low cutting pressure and thus minimise deformation of the elastomer.  Polished guide chamfers and ample back clearance prevent the gumming-up of the elastomer onto the back of the tool.  Hufschmied provides a large range of suitable push-type geometries such as the Z1, Z2 and Z3 end mills.

  • Thermosets

    Milling thermosets

    Thermosets cannot be plastically deformed after curing.  When reheated, they burn.  They are also remarkable inasmuch that they are not soluble in any solvent and do not display any swelling when in contact with plasticisers.

    Thermosets are used for the manufacturing of brake linings or chassis parts.  Furthermore, the matrix of fibre composites such as carbon fibre-reinforced (CRP) or glass fibre-reinforced (GRP) polymers is often made from thermoset materials.

    Thermosets comprise phenol-formaldehyde resin (PF), melamine-formaldehyde resin (MF), phenol-melamine-formaldehyde resin (MPF), urea-formaldehyde resin (UF) and silicone rubber (SI).

    Major material groups among thermosets are the epoxy resins (EP) and the polyurethanes (PU).  Tools from the Universal-Line and the Proto-Line lend themselves for this task.

    • Clean-cut edges at high feed rates

      With thermosets, the main aim is the absence of burrs and the quality of the cut edge at high feed rates.  Hufschmied tools from the Universal-Line and Proto-Line are optimised to meet these requirements and deliver quality without the need for post-processing.

  • Foam materials

    Milling foam materials

    Foam materials play an important role, especially in packaging.  In many cases, customised solutions are required that are best achieved by 3D milling.  Materials for constructive packaging and foam inserts are, for example, polyurethane (PU) or polyethylene (PE).  Expandable polypropylene (EPP) and expandable polystyrene (EPS) are also widely used.

    For soft and medium-hard varieties of these foam materials, DFO tools from the Universal-Line by HUFSCHMIED are ideally suited.  For hard foams, carbon cutters with high removal rates from the Fiber-Line can be used.

    • Sharp cutter geometries specific for soft foams

      With foam materials, any markings or imprints made during processing are not permissible.  Tools for the milling of foam materials must have a very sharp cutter geometry to avoid squashing the soft foam.  Since there are often large blocks to be processed, over-long tools with long blades or long back clearance are required.  We carry these in our standard range.

  • Acrylic glass/Plexiglas®

    Milling acrylic glass

    Acrylic glass, chemical name polymethyl methacrylate (PMMA), is a thermoplastic polymer and serves as a shatterproof and lightweight substitute for glass.  PMMA is used in a wide variety of applications – from the automotive industry and light technology to aeroplane construction.  Special emphasis should be placed on the role PMMA plays in medicine. Particularly in dental medicine, where acrylic glass is used for prostheses, PMMA is indispensable.

    For the milling of PMMA in cast or extruded form (Plexiglas® GS; XT), we recommend the use of our Fräsen Per Plex product range.  These single-flute milling cutters achieve mirror-finish surfaces without the need for additional polishing tools or additional polishing processes.

  • Block material

    Milling block material

    These days, block material is mainly used in model-making and fixture construction.  In particular, the relatively soft synthetic resin Ureol® is often the preferred material for CNC-milled prototype models, functional models, trade fair models and automotive models.

    For the milling of block materials, HUFSCHMIED provides a large number of ball nose-, torus- and shank cutters from its Proto-Line.  With their different coatings, our tools take account of the respective properties of diverse block materials.

    • Special cutter geometries for deep cavities, bars and pins

      For every processing challenge in the milling of block material, HUFSCHMIED supplies a straightforward and efficient solution.  Due to the specific cutter geometry, even the machining of pins, bars and deep cavities can be achieved – without leaving imprints or marks.
