Cut-Off Machines feature rotating cutting head

Graebener Group Technologies Ltd has announced the availability of the REIKA line of Compact rotating head tube cut-off machines, which cut and simultaneously face and chamfer the O.D./I.D. on both tube ends, saving time, manpower and floorspace. Unparalleled quality is achieved by holding the tube in a fixed position while the cutting head rotates thereby minimizing positioning error and eliminating any marking on the O.D. surface.

Compact machines currently deployed to European customer applications are producing at rates of up to 1,900 parts per hour making them a perfect choice for the high-volume automotive environment. The machines also have proven repeatability and consistently achieve tolerance rates of +/-0.05mm with Cpk>2.0. Capability includes ingoing tube length up to 65 feet and up to 3.5 inches in diameter with a minimum cut length less than 1.0 inch.

The rotary cut-off unit can be equipped either with standard carbide inserts or with roller blades for chipless cutting, depending on wall thickness and material. The clean, dry chipless cutting process reduces tooling cost and eliminates the need for washing operations thereby reducing initial investment and ongoing energy consumption.

The machines can be equipped with either Siemens or Allen Bradley Controls and all machines come with a state of the art tele-diagnosis system. All machine and tube transport axes are electromechanically driven eliminating the need for less reliable hydraulic systems. Subsequent measuring stations for length, roundness, straightness or customer specific measuring applications can be integrated with SPC-capability. Machines can also be equipped with flexible and fully automated stack out and bundling systems allowing a single operator to manage multiple machines simultaneously.
