Ÿ Innovative new geometries designed in conjunction with

our international development partners who have decades

of design and development experience in the carbide

tooling industry. The benefit is a range of state-of-the-art

carbide cutting tools with superior performance.

Ÿ

Ÿ Optimal flute geometry delivers maximum metal removal

rates and better chip evacuation.

Ÿ Effective in a full range of machine speeds, from

3 000 to 20 000 RPM's and more.

Ÿ Only one tool is needed for use in roughing and

finishing operations.

Ÿ Can take deeper and wider cuts - axial and radial. Slotting is

effective up to full 1xD axial depth. Side milling (profiling) is effective

up to 0.5xD radial by 1.0xD axial depth.

Ÿ Shank tolerances to h6.

Ÿ Reinforced corner by extra positive dubbing for long tool life.

Ÿ Centre cutting with drilling possibility.

Ÿ Designed to works standard over the 1mm to 20mm diameter range.

Ÿ Multiple corner radii and extended neck configurations are available to

maximise metal removal rates.

Sub-micron carbide grade of European origin.

The main features of these solid carbide

end mills for aluminium include:

Ÿ High stock removal rates at high speeds and feeds, excellent finish

quality and extended tool life are the major benefits of these ranges.

Ÿ Can be used in a wide range of applications, with excellent results achieved

in the aerospace, automotive and die and mould industries.

Ÿ Effective in high-speed machining, conventional milling and MQL

applications.

Ÿ Designed for customers machining a large amount of aluminium products

as significantly reduces machining time in aluminium cutting.

CODE

The current market trend is towards the increasing use of aluminium substrate in

the manufacture of die cut and moulds. Aluminium substrate offers many

advantages, such as excellent machinability and good thermal conductivity, as well

as being light in weight, with a high strength-to-weight ratio.

Due to the relative softness of aluminium, specific characteristics and geometries

in solid carbide end mills are required for efficient machining of this ductile

material.

Somta's high efficiency carbide end mill range with optimal flute geometry

provides all the required features for high performance machining of aluminium,

with the added benefits of greater stock removal rates at high speeds and feeds,

excellent surface finish quality and extended tool life.

The range allows for roughing and finishing applications in aluminium and other

non-ferrous materials and competes favourably with current global state-of-the-art

solid carbide cutting tool designs.

Somta has integrated a state of the art Walter Helicheck

Basic 3 into its quality check management process. The

Walter Helicheck is a 4-axis CNC measuring machine

for non-contact complete measurement of rotationally

symmetrical precision tools with complex geometry.
