Band saw machines: high performance with nesting cutting

ISTech machines have standard features including variable band speed with inverter, recirculating ball screw, automatic guide arm (with zero clearance carbide insert), hydraulic band tensioning, and head fast approach on the material to be cut. The machines have a power driven band cleaning brush and hydraulically driven screw type chip conveyor. A servo feed sensor keeps the blade cutting at optimum feed rates.

Depending on the surrounding area, the exhaust simply needs to be pulled down far enough to allow room for the cutter head to rotate around the pipe. No sawing or grinding is required, thereby eliminating the risk of injury to the user and avoiding any possibility of the underside of the vehicle being damaged by sawing or grinding. The cutting produces no swarf, so that no chips or swarf can enter the exhaust system. The cut is clean and needs no tidying up, so the new sections of the exhaust can be fitted immediately after the pipe has been parted off. This results in considerable time saving over conventional methods. The ratchet drive features automatic advance of the cutting wheel with every turn. The special alloy of the cutting wheel gives a long tool-edge life and ensures fast work, while the body of the pipe cutter is made from rugged, easy-care die-cast aluminium. The Dako No 224 ratchet pipe cutter is designed for parting plain steel, stainless steel, copper and aluminium tubes. It is available in two sizes – 16mm to 35mm pipe diameter and 35mm to 66mm pipe diameter – with wall thicknesses from 1.5mm.

The company also produces automatic cutting systems and customized machines for every special requirement. In the area of nesting cutting, ISTech offers a wide variety of solutions with different types of nesting fixtures. The best solution can be selected according to the shape and dimension of the material and the bundle. It is even possible to operate some of ISTech’s nesting fixtures without adjustment. Other nesting fixtures require some manual adjustments, but the bundle vice guarantees a minimum butt end. ISTech nesting fixtures are made up of one fixed vice mounted onto the machine frame, and one movable vice mounted onto the material feeder. These two vices, working together, guarantee a perfect clamping of the bundle and eliminates any possible vibration that can reduce the life of the blade. In addition, special plastic components are mounted on the vice clamping face to secure the bundle and absorb any residual vibration. All ISTech nesting fixtures are hydraulic and use the machine’s maximum cutting capacity.
