CIRCULAR SAW BLADES – HSS – DIAMOND LINE

These blades are not coated and are mainly used in manual cutting machines and semi-automatic machines. They are ideal for profile cutting, solid rounds and square solids.

APPLICATION

Aluminum, bronze, copper, brass and plastic.

Durability

Superficial Hardness <800 HV Oxidation Temperature  750 ºC
Friction Coefficient 0,25

The Chrome Diamond blades have an innovative PVD process which offers an increased tool performance. The great results obtained with dry machining prove that this coating enhances productivity.

APPLICATION
Low, medium and high carbon steel, Stainless steel, Hard steel and high cutting speed.

Durability

Superficial Hardness 3200 HV
Oxidation Temperature  1100 ºC
Friction Coefficient 0,35

This coating process increases the tool cutting edges stability. The increased hardness of the coating allows a better blade protection against abrasive wear and erosion. It is suitable to cut material with an elevated breaking load and stainless steel. It was specially developed to bear high cutting speeds due to the low friction coefficient.

APPLICATION
Low, medium and high carbon steel, stainless steel, cast iron, hard steel and high cutting speed.

Durability

Superficial Hardness 3300 HV
Oxidation Temperature  900 ºC
Friction Coefficient 0,25

PVD Coating

The Physical Vapor Deposition – PVD – is a technology used to deposit thin metallic layers on several types of substrate. The process is carried out under vacuum where the metals that will be deposited (zirconium, titanium, chrome) are evaporated. Due to the kinetic energy and the outstanding potential applied on the blade, the metallic ions are attracted to the blade surface to be coated, together with a process gas forming the desired coating.

The PVD is indicated to innovative products and that need to meet high tribological standards (surface hardness and abrasion, scratch and corrosion resistance).  Sul Corte’s PVD coating quality significantly contributes to exceed all expectations. With a work method directed to reach maximum excellence on all manufacturing process stages. In each coating type used by us it is possible to spot the result of years of experience aimed to solving all cutting processes, we search the highest quality indexes available in the market. With the PVD coating applied technology, Sul Corte offers:

  • HIGHER TOOL DURABILITY

  • INCREASED TOOL PERFORMANCE;

  • CUTTING TIME REDUCTION

  • BETTER CUT PIECE QUALITY

BLADE COATING MEASUREMENTS

Each coating produced by Sul Corte has unique features to attend specific demands for each cutting need. With the PVD coating the blades will offer an excellent wear and temperature resistance, being able to offer a considerable hardness increase. It will result in a better tool performance. In order to achieve this, it is necessary the ideal coating proportion according to the blade diameter.

RAW MATERIAL QUALITY

In order to achieve the best finished product possible each small detail is very important that is why Sul Corte constantly seek the best raw material that can be found in the market. The right steel composition used on the HSS blades results in a better tool performance, in order to achieve the best performance it requires high quantities of tungsten and molybdenum, responsible for the hardness and wear resistance. The steel chemical composition has many elements and each one with its own specific properties, both chemistry as physics.

The chemical elements present in the speed steel composition are: chrome, tungsten, vanadium, and in smaller quantity cobalt, molybdenum and aluminum. The correct combination of these elements results in the high qualification of its mechanical properties, such as resistance in the high cutting temperatures, hardness, wear resistance and tenacity. A high carbon content enhances the bond strength providing higher wear resistance. The chrome content can significantly reduce oxidation avoiding mechanical or chemical tool damage. The molybdenum content makes the steel tougher avoiding tool breakage.

Teeth Types

TYPE A

The tooth type A is normally used for brass alloys, jewelry and screw carvings.

TYPE B

The tooth type B is normally used for pipes with thin walls and structural profiles, especially where the chip removal is not a problem

TYPE AW

Unlike the type A, the tooth type AW is alternately beveled, optimizing the chip breakage. It is particularly indicated to precision cuts.

TYPE BW

The tooth type BW is normally used for pipes and profiles cuts. The tooth is alternately beleved at 45°, this allows the blade to break the chip into two parts providing a better exit of the chip.

TYPE C

The tooth type C is normally used to cut solid sections or pipes with very thick walls. The chip is broken into three parts. A higher tooth with two beveling parts, one in each side, is responsible for the pre-cut. The next tooth, with no beveling, is responsible for the finishing.

TYPE BS

The tooth type BS was developed to cut pipes only. It has doubled cutting edges; this provides a higher cut number and a better finishing to each section. It also improves in 20% the tool durability because it reduces the removed section in each blade course.

TYPE VP

The tooth type VP has a variable pitch, is used to cut very irregular sections that causes vibration and noise. It provides a smoother contact and has a great relation between durability and reduced vibration.

Tooth Geometry and Cutting Angles

Choosing the best angle and teething type is very important as it is fully connected with the requirements of finishing and tool life. In order to facilitate the process, Sul Corte developed the ideal parameter according to the customer needs. Below you can find the correct tooth geometry for the HSS circular saw blade and the main characteristics in relation to most used teething (BW, C, BS) as well as the dimensions of the cutting and relief angles, concerning the most common materials.
