Surface Of Treatment(Coating):

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 offersan 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.

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

Tips:How to choose pitch of the saw blades?

To choose appropriate pitch can extend life of saw blade and enhance efficiency.

Basic data are as following.

As thickness is thicker, pitch will be larger. On the contrary, it is thinner, pitch will be smaller.

As material contains much viscosity, pitch will be larger. On the contrary, it contains less viscosity,

pitch will be smaller.

If you want to get fine surface, pitch has to be small.

If you want to cut in hurry, pitch has to be large.

In other words, pitch is changed depending on thickness, kind of material. As pitch is larger, the number of teeth will be less and cutting speed will be slower. However, even though material is strong, it is impossible to prescribe the pitch size. Because, as material is stronger, you can preadjust cutting speed then you can get same effect to adjust pitch.

If pitch is too large, surface will be rough and saw blade will be made load. So it will be easy to wear or to be broken. On the other hand, pitch is too small, chips of work piece can`t be pushed out, it will be wore or broken.

Generally, pitch is chosen by DIN dimension 1837-8, from our express, the way of choosing pitch is as follows:

When you cut the high tensile iron and steel, alloy steel and stainless steel, you had better use pitch which is lower one step than structural steel.

When work piece is nonferrous tube or profile, basically copper is around 5p and aluminum is around 8p. In solid bar case, depending on size and hardness of surface, it has to be increased and decreased.
