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 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.

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

How to choose shape of teeth?

Appropriate choosing of teeth form is related to material and profile of work piece and, it affects tool life and safety.

There are 5 kind of teeth forms as following.

Regarding DIN 1840:

A : This is usually used for cutting mild steel which is easy to be broken and cut. This is accepted

2mm~4mm pitch or more.

AW : This is almost same as A, except for chamfering in turns. Nowadays, this is hardly used, then

A or BW are used instead of this.

B : Because it is changed straight part of A into curve, pocket of chip is bigger. So its pocket is bigger

than A and it is able to cut thick material

BW : This is almost same as B, except for chamfering in turns. This load is less than B, and it is

suitable to cut thick material.

This is applied to cut nonferrous pipe, profile and heavy metal solid bar.

Usually, A or B is used for CUTTER, and BW or C is used for SAW.

C : C goes by the name of HIGH-LOW form. There are two kind of different height teeth, and difference

of between two teeth is 0.15~0.3mm. It is cut both side on the high tooth face, and at the same time,

it is also removed chip. This is possible to be processed when the thickness of saw blade is proper

to be ground. This is used for cutting round solid bar, rectangle solid bar, heavy metal and thick pipe.
