1. Methods of processing without a shaving.

• Sharp
  Sheets KOMATEX, thickness up to 3mm, it is possible to knife easily. Thicker sheets KOMATEX cut a manual or electric saw. Scooters or electric scissors do not give satisfactory result because the material is compressed at edges.
  
  
• Punching
  Quality of punching is defined with following factors: thickness of a leaf which will stamp, temperature of a leaf, equipment for punching, and also a corner of cutting of an edge.
  
  - Thickness of sheets
  Sheets KOMATEX, of thickness 2 and 3mm, is stamped easily. However, at the correct equipment and correct methods simple forms can be stamped from sheets, thickness from 4 up to 6mm. But thus edges will be sharp are rounded slightly off.
  
  - The temperature of leaf
  KOMATEX is a thermoplastic which becomes soft at rise in temperature. The quality punchings can be frequently improved by means of small heating of a leaf.
  
  - Equipment for punching
  Tools for punching the cardboard, the made foam materials and plastics also approach and for KOMATEX. Steel cutting torches for cross-section approach are sharp, thickness 0,7 - 1mm and width 15-18mm, established in wooden boards, thickness 15-18mm. For straight lines and slightly curved forms it is necessary to use edges with a degree of rigidity 4, whereas for radiuses it is less 10mm degree of rigidity should be 3. Compressed elastic materials should be used, as ejectors, and their thickness should steal up according to height of an edge and used leaf KOMATEX.
  
  - Corner of cutting of an edge
  At stamping KOMATEX it is absolutely important, that edges have been oblique.

2. Methods of machining processing

• Sawing
  KOMATEX it is possible to saw a manual, disk, tape saw and a fret saw. Good results give manual saws, intend for work on a tree. Saws, intend for work on metal, because of their fine step barbs are inclined to a contamination, and can be used restrained better quality is reached at speed sawing up to 300m/min. and at submission about 30m/min.
  
  Parameters of drilling:
  the main forward corner barbs: 5 - 10^o
  corner of a backlash: 10 - 20^o
  Step barbs: 2 - 5 barbs on everyone 2,5cm.
  
  
• Drilling
  KOMATEX can be drilled standard screw drills, intend for metal. Better quality is reached at speed of a drill 50 - 30 turns/min. and submission 3,5 - 6 m/min.
  
  The form of drill
  corner between a cutting edge and an axis of rotation: 100 - 110^o
  Corner of rise: 30^o
  The main forward corner: 0
  
  
• Milling
  KOMATEX is easy for processing on standard universal vertical or horizontal milling machine tools. To prevent damages on surfaces from fixing wooden or plastic linings are necessary. It is important to use correctly grinded tools on plastics with correct frequency shavings cleaning.
  
  Parameters of milling by results of practical tests:
  Speed of sharp: about 900m/min
  Corner of a backlash: 10 - 25^o
  Main forward corner: 5 - 20^o
  
  
• Processing of edges
  Edge can finaly be processed by a plane, an emery paper or sawing by means of the standard equipment on a tree or plastic. When the material is exposed to constant dynamic loadings, rough cuts can lead to formation of cracks and breaks.
