DANOBAT launches DS 3A horizontal cutting band saw machine

The DS has a feeding system that automatically sets the component in the cutting position already defined by the operator. In order to improve the process, the chariot moves only when the length of the component requires it to do so. The material is clamped on both sides of the blade, the fixed arm is attached to the head achieving more rigidity, and the movable arm moves by means of a linear guide and is automatically adjusted to the width of the material together with the vice. Thanks to this automatic system it is possible to reduce the distance between guides and increase the speed and the quality of the cut. All these improvements that have been made in the design of the machine have increased the blade life even in hard conditions. (For example: testing the machine cutting carbon steel with aggressive times achieves 18-20m 2 ). This model is equipped with a control panel and software specifically developed by ©DANOBAT, which allows the programming of different cutting lengths of component from the same bar without making any change.

materials that provide to the machine the necessary rigidity to achieve a clean and accurate cutting. Blade guiding is done by a combination of bearings and hard metal plates fitted on plate holders, allowing any realignment of the blade position. Both columns – the main round column and the secondary prismatic column – are designed to absorb the deformation produced by blade tensioning.

DANOBAT, a company that has developed innovative machines for more than 55 years, has launched the new DS 3A horizontal cutting band saw machine, which is characterised by its quality and modern design. The DS is a versatile machine that allows users to cut different geometries, within solid components and tubes of different materials with high accuracy. The main components of this model are manufactured with high quality

Caterpillar, Komatsu, Wipro India and JC Bamford Excavators Ltd. The SIERRA USA ® is quality built with technology, features and tooling not found in competitor’s products. The SIERRA USA ® offers greater speed, increased cost efficiency, and high quality machining solutions to serve the cylinder manufacturing industry. A skived and burnished surface provides longer seal life and has a 50 per cent higher TP rating than that of a honed surface.

The speed and efficiency of the SIERRA USA ® can handle 88.9mm bore tube 762mm long finished in 30 seconds including loading and unloading – 122 tubes per hour, achieving H8 and Ra 0.1-Ra 0.4. Skiving and burnishing is 80 to 100 times faster than honing. Sierra Machinery Inc – USA Email: sierram@sierramachinery.com Website: www.sierramachinery.com
