At this year’s EMO exhibition in Milan Pavilion 18, Stand B13, Starrett will show a number of recently launched sawing machines and new blades developed specifically to increase customer productivity. The company’s 63 m2 stand in the ‘Band Saws, Blades and Sawing’ hall will feature live cutting demonstrations.
Ideally suited to a wide range of industry sectors, the Starrett S4230 and S4240 semi-automatic machines will be demonstrated. Featuring state-of-the-art technology that has been specifically adapted to increase the capabilities of the band sawing machines, both feature cast iron bows for vibration damping and longevity, a minimal footprint and controlled hydraulic blade feed.
The S4230 supports productive cutting and is able to cut mitred corners on both the negative (-45o) and positive sides (60o). Fitted with a 
1.5 kW motor, it can cut material up to 300 mm diameter or 270 mm square. The 2.25 kW motor on the S4240, combined with a rigid structure, creates a semi-automatic band saw that is ideal for intensive use and for cutting harder materials up to 300 mm diameter or square. It can also cut mitred corners at angles of between -45o and 75o, making it ideal for intricate work.
A fully-automatic CNC machine, the S6330 has a blade speed between 20 and 100 m/min controlled by a variable frequency drive. A dual column design to balance the cutting forces generated ensures precision and stability. The S6330 will be used to demonstrate the exceptional cutting capability of Starrett’s carbide band saw blades for hard and abrasive metal cutting applications. New carbide tipped blades at the show will include the Advanz MC5 and Advanz MC7, both featuring positive rake angles and ground teeth geometry that has been specifically developed for a group of materials.
Advanz MC5 trapezoidal cutting tooth geometry has been designed to create five chips as the blade passes through the raw material. It is
ideal for highly productive cutting of ferrous metals at a reduced cutting time while achieving an excellent finish. Applications include automotive aluminium cast blocks, cast iron, bronze and copper on machines with hydraulic feed control.
As the name suggests, the trapezoidal cutting tooth geometry on the Advanz MC7 generates seven chips. This allows the blade to cut difficult materials such as mechanical construction steels, tool steels, stainless steels, Inconel and titanium, using a similar chip loading principle to that applied during high speed machining. Slow, heavy cuts are replaced by faster, lighter cuts resulting in quicker cutting action that is less detrimental to the machine’s components.
As well as carbide tipped blades, Starrett will also highlight its Versatix MP blades with a special tooth geometry developed for cutting structural materials with increased tooth strength, and Primalloy that features a high cobalt and vanadium content on teeth to guarantee longer blade life with high quality surface finish, increased wear and heat resistance, easy penetration in hard and difficult to machine materials, increasing the blade performance and resulting in cost-effective cuts compared to conventional bi-metal blades.
