Tungaloy's Modular Turning System Extends Tool Life

Tungaloy’s ModuMini-Turn exchangeable-head modular turning tool system for Swiss machines now includes new QC16 line that features 16 × 16 mm square shanks.

ModuMini-Turn features a unique coupling of the head and shank interface that is said to provide the insert cutting point with a precision of 5 μm or smaller when the cutting head is re-assembled to the shank. This enables quick tool changes in Swiss machines for minimum downtime.

The new QC16 line offers toolholders with 16 × 16 mm square shanks and the matching modular cutting heads. The new line features an enhanced coupling that is reportedly capable of sustaining high cutting edge repeatability and tool rigidity when used for applications generating greater cutting loads that the previously released QC12 line was not able to provide reliability with. The QC16 line also offers an array of modular cutting heads to accommodate various types of inserts, including standard ISO-positive inserts for forward and back outer-diameter (OD) turning, grooving and threading inserts, as well as double-sided MiniForceTurn negative inserts with positive cutting edges. In addition, modular cutting heads for Y-axis turning are also available, enabling shops to use elevated feeds and speeds to gain productivity of small part machining.    

Integrating the CHP internal coolant channel system, which is capable of high-pressure coolant supply, ModuMini-Turn toolholders directs the coolant jets precisely to the cutting point close to where it is required for better chip control and extended insert tool life.
