Range of Toolholders for PrimeTurning Methodology

Sandvik Coromant has released a range of CoroTurn Prime multitask and axial-type toolholders to help machine shops implement the new PrimeTurning methodology, which enables turning in all directions. This range enables users to maximize the benefits of the method on multitasking turn-mill centers and vertical turning lathes (VTLs).

One of the highlights of the range is the CoroTurn Prime Twin toolholder for multitasking machines. Both Prime A-type and B-type inserts can be mounted together on these toolholders, allowing manufacturers to undertake roughing with a B-type insert before switching to finishing with an A-type insert, for example. Modern multitasking machines are intended for the complete machining of components, but typically have a slow tool changing time, often around 15 to 20 sec. The CoroTurn Prime Twin holder is intended to save time when changing tools.

As a further advantage, B-axis machining on multitasking 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 time savings and productivity increases to enable manufacturers to reduce tooling inventories and achieve competitive gains.

The company is introducing six multitask toolholders which are mounted at a 45-degree angle for B-axis machining. They can be used with either A-type or B-type inserts. Options for multitasking machines include four toolholders (only one insert) and two twin toolholders (two inserts). The toolholder is available for use in Coromant Capto sizes C5 through C8.

New options include a range of axial toolholders for VTLs. This type of toolholder is compatible with most types of vertical lathes and available in Coromant Capto for use with either A-type or B-type inserts.

The company now has a complete offer for PrimeTurning including axial, radial and multitask toolholders. In total, eight dedicated toolholders for axial mounting are now available.

Although PrimeTurning is applicable to the entire general turning area, machine shops with large batch sizes are set to benefit most, as will those machining large components for which there is a need to reduce tool changes, setup time and production stops.
