Designed to cut deeper

Based on decades of experience designing and producing saw blades, all of Starrett’s knowledge and expertise has been applied to the design and build of the semi-automatic machines to provide class-leading material cutting performance. 

Ideally suited to a wide range of industry sectors the Starrett S4230 and S4240 semi-automatic machines feature state-of-the-art technology that has been specifically adapted to increase the capabilities of the band sawing machines. As Technical Support Team Leader, Graham Munro, explains: "Within many manufacturing businesses the band saw often suffers from mistreatment, and is seen as the ‘ugly step-sister’. With this in mind we have designed and built the Starrett machines for ease-of-use, they are very robust with reliability levels twice the industry norm, to help stand up to any harsh treatment.” 

Both the S4230 and S4240 are semi-automatic band saws that 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. 

Both these semi-automatic band saws are equipped with features designed to make their operation as simple as possible, such as Dynamometric blade tensioning. This easy to use feature allows the saw operator to correctly tension the saw blade without any tools. A manual handle is wound to apply tension to the band, with a graduated gauge providing accurate feedback when the correct level of tension is reached for the blade width fitted to the machine.
