The T-DRILL Rotary Cut-off Machine with in-line endformer can perform the cutting of tube simultaneously with grooving or endforming (e.g. expanding, reducing, beading, flanging, flaring etc.).
Reduced labor by combining operations into a single machine
Improved quality control
Reduced floor space requirements
Improved inventory control

The advantage of the T-DRILL Rotary Cut-off system is that the machine maintains the nominal O.D. with burr-free I.D. The presence of burrs would interfere with the loading of the tube to the end forming machine. In the end forming operation, burrs on either the ID or OD of the tube affect the tool's ability to maintain tolerances or generate the final shape.
T-DRILL rotary cutting makes the secondary deburring and washing procedures unnecessary. The lead end of the tube is end formed simultaneously with the cutting operation which significantly reduces the processing time as no tube handling is required between cut-off and end forming. After processing, the tube will be either pulled or broken apart depending on the length of the product. This method guarantees significant savings, not only in time but also material.
Standard end form tooling can be used (e.g. Manchester type). The endforming happens in 1 - 6 phases (1 - 6 hits) depending on the machine type. With a 6-hit end forming machine even the most complicated tube end shapes are achievable.
In addition to handling soft materials (copper and aluminium) the machine has been developed especially to meet the requirements of harder metals, such as steel and stainless steel.
Rotary tube Cut-off with in-line Endforming accepts tubing from either straight lengths or from coil stock. Straight tubes are fed into the system automatically from a rackloader that incorporates software specially designed for minimizing tube wastage. The machine is equipped with a predetermining batch counter that turns the system off after the desired number of cuts.
