Working with secutex

EASY TO WORK WITH

It is just one of the material’s characteristics. As all other PUR products, secutex also experiences a volume reduction of 1-3 % during processing. secutex castings comply with the tolerances of M3 DIN 7715. Casting elements can be optimised in order to obtain accurate results. Our CNC-controlled processing machines also allow an extremely accurate mechanical tolerance.

MILLING

Use standard milling cutters with a low number of teeth.
Important! Peripheral speed approx. 200-400 m/min, clearance angle α 10°, effective cutting angle γ 25°. It is recommended to use a drilling emulsion for preparing the surface and cooling.

CUTTING AND SAWING

Want to cut or saw secutex yourself? Just ensure that blades are extra sharp for cutting secutex. A band saw can be used to saw the secutex material. Due to the excellent abrasion properties, the material attempts to withstand or evade the cutting tool. Ensure a low wedge angle and adapt the cutting speed, where necessary.

CHISELLING

Knife-like implements as used for woodworking are best suited for this purpose.
Important! The tool angle should be 15°. It is recommended to use a drilling emulsion for preparing the surface and cooling.


DRILLING AND THREAD CUTTING

No special tools are required. Normal wood and metal drills suffice.
Important! Cutting speed approx. 40 m/min., advance approx. 0.01-0.03 mm/rev. In the case of low shore hardness, secutex can evade the tool. The hole could therefore be up to 5 % smaller.

TURNING

For this purpose, standard SS turning chisels can be used (tool angle 12°, β = 53°, γ = 25°).
Important! Cutting speed approx. 300- 500 m/min, hardness < 80° Shore A, 100-200 m/min, hardness < 90° Shore A. Advancing speed approx. 0.1-0.2 mm/U. It is recommended to use a drilling emulsion for preparing the surface and cooling. The harder the secutex material, the better the surface quality. For finishing, the use of a belt grinder is recommended.

GRINDING AND ROUGHENING

secutex can be easily ground with grinding machines or belt grinders (standard grain size or ceramic bonding).
Important! Grinding speed of approx. 30-50 m/sec. Wet grinding is recommended. Note: a wire brush can also be used for roughening.
