PrimeTurning™ now accessible on
multi-task machines and VTLs
Cutting tool and tooling system specialist Sandvik Coromant has unveiled a new range of CoroTurn® Prime multi-task and axial type tool holders to help machine shops implement the new PrimeTurning™ methodology, which enables turning in all directions. The introductions allow users to maximize the benefits of PrimeTurning™ on multi-task turn-mill centers and vertical turning lathes (VTLs). Complementing the company’s existing radial tool holders, Sandvik Coromant now has a complete offer for PrimeTurning™ operations.
One of the highlights of the range is the CoroTurn® Prime Twin tool holder for multi-task machines. Both CoroTurn® Prime A-type and B-type inserts can be mounted together on Twin tool holders, allowing manufacturers to undertake roughing with a B-type insert before switching to finishing with an A-type insert, for example.
‟Modern multi-task machines are intended for the complete machining of components but typically have a slow tool changing time, often around 15–20 seconds,” says Håkan Ericksson, Product Manager General Turning at Sandvik Coromant. ‟As a result, the new Twin holder will save customers a considerable amount of time when changing tools.”
As a further advantage, B-axis machining on multi-task machines permits the operator to program the angle of the tool in precise increments. When the machine cuts using its B-axis, more accessibility is created using neutral holders. In combination with streamlined operations, this accessibility delivers the potential for huge time savings and productivity increases to help manufacturers reduce tooling inventories and achieve competitive gains.
Six new multi-task tool holders are being introduced, which are mounted at a 45° angle for B-axis machining, and can be used with either CoroTurn® Prime A-type or B-type inserts. Options for multi-task machines include four tool holders (one-insert only) and two Twin tool holders (two inserts). The CoroTurn® Prime Twin tool holder is available for use with Coromant Capto® C5 – C8 size.
A range of axial tool holders for vertical turning lathes is also part of the range, which means that Sandvik Coromant now has a complete offer for PrimeTurning™: axial, radial, and multi-task tool holders. In total, eight dedicated tool holders for axial mounting are being launched. This type of tool holder is compatible with most types of vertical lathes and available in Coromant Capto® for use with either CoroTurn® Prime A-type or B-type inserts.
Although PrimeTurning™ is applicable to the entire general turning area, machine shops with large batch sizes (automotive) are set to benefit most, as will those machining large components (aerospace) where there is a need to reduce tool changes, set-up time, and production stops.
Ultimately, the all-directional PrimeTurning™ method and CoroTurn® Prime tools will ensure that manufacturers can complete their turning operations in a much more efficient way. Compared with conventional turning, a 50–80% increase in productivity, along with 1.5–2 times more tool life, can be achieved.
