Grooving Tungaloy gets groovy with new turning line
As part of its Addforce global launch of next-generation cutting tools, Tungaloy UK has now introduced the new Add Internalcut to its product portfolio. The new Add Internalcut 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 new clamping system that is incorporated into the tool body to provide a higher level of clamping rigidity and indexing repeatability and precision. The new Add Internalcut 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 Add Internalcut is available with a steel or carbide tool body with a necked relief of 24 or 30 mm to provide sufficient clearance and swarf evacuation. The round tool shanks also have 12 mm 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 125 mm and an insert seat size of 10.
To ensure the new Add Internalcut is suitable for a wide audience, Tungaloy has developed the range with its CWN and CWX insert designations. The CWN is 1.5 mm wide with the heavier duty CWX being 2.5 mm wide. Depending upon the chosen insert geometry, the Add Internalcut provides a protrusion for cutting at depths up to 2 mm. Both insert geometries are available in Tungaloy’s AH725 insert grade that is PVD coated. This makes the new Add Internalcut suitable 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.
Ideal for cutting inside holes from as small as 10.5 mm diameter and upward, the Add Internalcut is available with right and left-hand toolholders. Not only is the Add Internalcut a flexible system, but its highly rigid clamping design also maximises rigidity and clamping forces to extend tool life, precision and repeatability.
