This wolfram-molybdenum high-speed steel also contains 5% cobalt, offers higher hardness and is therefore suitable for cutting stainless steels and materials with high mechanical resistance. |
TOOTH SHAPES / TOOTHING
In order to adapt our saw blades to various applications, different tooth shapes are available. For best toothing and sharpening results we only use hi-tech CNC machines that solely use CBN grinding technology. Therefore we can guarantee the best cutting performance and long blade life.
SURFACE TREATMENTS / COATINGS
By using certain surface treatments and coatings, cutting performance can be increased and blade life can be extended in order to reduce cutting times and cost / cut. The following treatments and coating are available:
POLISHED
A polished blade is the simplest saw blade without any surface coating. It is suitable for low-end applications on manual machines.
STEAM TREATED
This is currently the most common surface treatment for circular saw blades. The steam treatment creates a hard oxide layer on the blade and is the simplest “coating” available. It is used for general cutting applications, except for aluminum, copper, brass and their alloys.
GOLDFACE (TiN – Coating)
The GOLFACE coating gives the blade a great surface hardness. The high oxidation temperature, together with other positive characteristics, makes it possible to work at cutting and feed rates approx. 50% higher than with an untreated blade. Cutting times are reduced and blade life is increased. GOLDFACE blades are suitable for cutting of mild steels (500 – 750 N/mm2).
SPEEDFACE (TiCN – Coating)
This is a multi-layer coating with a low friction coefficient that offers an excellent finish at very high cutting and feed rates. It can be used for hard steels (800 – 1000 N/mm2), for copper and brass alloys and for extremely abrasive materials where the phenomenon of “chip welding” can be a problem.
MULTIFACE
This is a multi-purpose coating that guarantees high cutting performances for various cutting requirements.
BLACKFACE (TiAlN – Coating)
Suitable for stainless steels, materials with high tensile strength and abrasive materials such as cast iron, silicon aluminum alloys, brass and copper. Due to its low friction coefficient this coating is also suitable for dry-cutting at relatively high cutting speeds.
BESTFACE (CrN - Coating)
Characterised by a high surface hardness and low friction coefficient (the lowest of all), this coating is particularly suitable for cutting pasty materials such as copper, brass and bronze. Thanks to its high corrosion resistance this coating is also ideal for some plastics and applications where high temperatures and corrosion phenomena could develop.
ACTIVEFACE
High performance coating for cutting high tensile strength materials, stainless steels and abrasive materials. Thanks to its high oxidation temperature (approx. 700°C) and low thermal conductivity, this treatment is suitable for dry-cutting at relatively high cutting speeds.
