Tungaloy introduces new internal grooving line

1 min read

As part of its ADDFORCE global launch of next-generation cutting tools, Tungaloy UK has now introduced the exciting new AddInternalCut to its product portfolio.

The new AddInternalCut is an industry first, introducing four cutting edges on an internal grooving tool for precision turning and small part machining applications.

The R&D experts at Tungaloy have developed a unique new clamping system that is incorporated into the tool body to provide an astounding level of clamping rigidity and indexing repeatability and precision. The new AddInternalCut supports the four-edged insert in three positions with each of the cutting edges protected by the ingenious new pocket design. Furthermore, this design allows end-users to use the same insert on a right or left-hand tool body.

The AddInternalCut is available with a steel or carbide tool body with a necked relief of 24 or 30mm to provide sufficient clearance and swarf evacuation. The round tool shanks also have 12mm flats to correspond with everything from sliding head turning centres through to larger more robust lathes. The through coolant tool bodies are optimally manufactured to reduce vibration and chatter with an overall tool length of 100 or 125mm and an insert seat size of 10.

To ensure the new AddInternalCut is suitable for the widest possible audience, Tungaloy has developed the range with its CWN and CWX insert designations. The CWN is 1.5mm wide with the heavier duty CWX being 2.5mm wide. Depending upon the chosen insert geometry, the AddInternalCut provides a protrusion for cutting at depths up to 2mm. Both insert geometries are available in Tungaloy’s AH725 insert grade that is PVD coated.

This makes the new AddInternalCut the first choice for cutting a wide variety of steels, stainless steels and challenging aluminium alloys such as titanium. The geometry of the inserts guarantees a sharp cutting edge for maximum precision whilst the ground-to-form chipbreaker enhances groove precision whilst working in tandem with the through coolant facility to evacuate the swarf.

Perfect for cutting inside holes from as small as 10.5mm diameter and upward, the AddInternalCut is available with right and left-hand toolholders. Not only is the AddInternalCut a flexible system, but its highly rigid clamping design also maximises rigidity and clamping forces to extend tool life, precision and repeatability. With the system also being a four-edged series, the AddInternalCut is the most economical grooving line in the industry. For further details, please contact Tungaloy UK.
