HM circular saw blades for the cutting of aluminum and its alloys, copper, brass, bronze, lead, magnesium, titanium
- thin, medium and high section profiles
- solid in bars, rods, sheets, plates with high sections of material
To be used on manual bench machines and / or automatic machines:
- Operating speed 40-90 m / s
- High finishing and cutting precision
- High feed cutting process according to the section and quality of the material to be cut
- High chip removal
- Maximum efficiency and duration
- Silencing slots with application of sound-absorbing material
Body blades steel
Steel used for the construction of the body blades is hot or cold rolled.
There are two main categories:
- 80CrV2: for medium / high applications with high stress
- 75Cr1: for standard applications
Teeth
The choice of high quality carbide, to be used for cutting different materials, is directed towards various types of quality of micro / fine / medium grain inserts, to ensure greater durability of the circular blade, greater resistance to shocks and limited wear of the tooth.
The choice of the right number of teeth varies according to the type of automatic cutting.
It depends on various factors, such as type and state of the material and its thickness.
The mainly used cutting geometry is the trapezoidal-flat, in groups of four or five teeth, with nail or chip breaker groove.
Positive or negative cutting angles are designed to ensure optimal penetration into the material to be cut, with smaller radial and tangential angles, designed to reduce wear of the tool.
Execution of nail chip breaker
We produce all sizes, number of teeth and thickness.
Diameter: from 30 mm up to 2200 mm
Thickness: from 1 mm up to 15 mm
The following table shows just a few of the most commonly used diameters, number of teeth and thickness.
