C utting , S awing & S aw B lades Circular saw blades

STARK SpA leads an industrial group specialised in HSS and TCT circular saw blades for a full range of metal cutting applications. A strategic network of distributors and agents grants customers commercial and technical support at any time. The Millennium HSS blade is the company’s latest solution for tube cutting with high tensile strength steel, high temperature in the cutting area, internal scarfed tubes, and low cutting time for high line speed production. Stark claims that in all these cases the

HSS blades; the material of the blade together with the coating and the low production tolerances help to obtain results in durability and cutting time. The Premium TCT blade is suitable for use in tube cutting where even the best HSS blade is not adequate in cutting time or in pieces to be cut. The blade features a specific PVD coating developed by Stark. Stark SpA – Italy Fax: +39 0432 999552

A new generation of laser cutting equipment THE Stiefelmayer effective laser cutting machine integrates technologies that make it both efficient and productive. of efficiency and are suitable for thinner sheets. They also allow greater cutting speeds.

In combination with high-performance linear motors, products are manufactured quickly with great precision. The fibre guide transfers the precision of the machine to the component without deviation. Fibre systems are completely sealed and so require no maintenance; no flushing of the beam path, no reflectors to adjust, and no special gas for the laser. The machine features a conveniently operated table system with fast table changeovers and a user-friendly operating interface.

Modern lasers require less power for cutting yet have three times the degree

To translate these higher cutting speeds into shorter production times, the machine

was upgraded to use the latest technology, setting new standards for dynamics and precision. The weight of all moving parts was optimised by using modern materials developed for aerospace and racing applications. These contain carbon fibres to achieve superior strength with minimal mass – a prerequisite for high contour accuracy at high cutting speed.

Nanocomposite coated blades offer improved tool life

ICO Surface Coatings, a division of Tru-Cut Saw, has developed a new nanocomposite PVD coating to increase blade life for circular ferrous and non-ferrous saw blades. Saw blades coated with the new ViTA- Nano material will run a claimed 30% faster, with lower cycle times and increased production rates compared to AlTiN coatings. Richard Otter, VP sales ICO Coatings, commented, “Flying saw machines, re-cut machines and high production sawing machines will see immediate cost benefits in longer blade life when sawing with the ViTA-Nano coating. We’re working hard to ramp up production and currently are PVD coating about 600 blades per day.”

ViTA-Nano blades are more effective than AlTiN when sawing hardened steels, cast iron, aluminium and super alloys, and are able to withstand temperatures that are 300°C (550°F) hotter. The blades last longer because edges are protected for a longer period of time from steel build-up that ultimately reduces tool life. ICO Surface Coatings recommends dry cutting with VITA- Nano blades to further reduce coolant costs. The company’s research and development centre is currently working on the next generation of super hard ViTA- CrX nanocomposite coatings for industrial sawing applications. ICO Surface Coatings offers PVD coating

and re-coating services for all types new and used tools and wear parts. Equipped with state-of-the-art coating chambers and carousels, ICO offers both standard and special surface treatments. Standard coatings are CrN, TiN, TiCN, AlTiN-ML, AlTiN- XL, AlTiCrN and TiAlCN Phoenix™. Special and tool-specific coatings can be individually tailored to specific customer requirements, and coating chambers can handle part sizes up to 1,250mm OD x 700mm.
