Vargus Ltd., one of the world’s leading manufacturers of high-quality thread cutting, grooving and deburring tools for the metals and plastics industries, showcased there latest product at IMTEX 2015. According to the company, the new VRX multipurpose thread turning grade from Vardex is a step forward for them.

“The launch of the new VRX grade marks a significant step forward in our market position as a leading provider of advanced threading solutions. We invested extensive resources in the technological development of VRX in
response to calls from our customers for a high performance threading grade suitable for a wide range of materials and cutting conditions,” said Harry Ehrenberg, President, Vargus Ltd.

Suitable for machining steel, hardened steel up to 55 HRc, stainless steel, high temperature alloys and non-ferrous metals at low and high cutting speeds, VRX grade inserts are available in sizes IC 3/8” and IC 1/4” and suitable for all standard thread turning profiles. In the future, the VRX grade will be extended to additional sizes and products throughout the Vardex line.

The VRX grade comprises a multitude of nanometric layers that are composed of alloyed composite materials. An advanced adhesion process binds these layers together to form a tough multi-layer structure that provides stronger wear resistance, a longer tool life and better productivity.

“Our internal lab tests and field reports confirm our belief that VRX will soon become a new benchmark in our industry. The new VRX grade outperforms our leading competitors regardless of the cutting material or conditions. We look forward to continuing this trend in the future with an ever growing stream of new product solutions in 2015 and beyond,” added David Wolfe, VP Sales & Marketing, Vargus Ltd.

VARGUS GENiusTM, VARGUS’s leading thread turning software program is updated with the new VRX grade inserts.

High precision nozzles put coolant pressure exactly where it’s required

Sandvik Coromant has announced that its CoroTurn® SL cutting heads now feature CoroTurn HP (high precision) nozzles that direct cutting fluid precisely where it is needed – at the exact interface between the tool and the workpiece. This innovation ensures CoroTurn SL users can be assured of reliable chip breaking, which facilitates both good chip evacuation and extended tool life in back-boring operations.
​
The extended product range offer includes cutting heads for coolant up to 70 bar pressure. Designed to suit back-boring operations with clearance between body and component, the heads are available in 25 and 40 mm sizes, to suit positive D and V style inserts.

CoroTurn® SL is a universal and modular system of adaptors with exchangeable cutting heads where customers can build customized tools for a variety of machining applications. The ingenious Serration Lock (SL) interface is extremely robust and lets users create a range of tool combinations from a small inventory of adaptors and cutting heads: just three bars and three heads allow up to nine different configurations. What’s more, CoroTurn SL cutting heads have four stages of offset up to 23 mm. This enables reach and the largest possible boring bar diameter, making it ideal for challenging operations in the aerospace and oil and gas industries, such as bottle boring (also called chamfer boring). Here, SL adaptors are ideal in combination with Silent Tools dampened boring bars for operations with long overhangs or vibration tendencies.

The CoroTurn HP fixed, pre-directed high precision nozzles featured on the new heads deliver parallel laminar jets of coolant with high velocity. While positive effects start at low coolant pressure, more demanding workpiece materials can be machined as the pressure climbs.

Ultimately, for efficient coolant delivery, Sandvik Coromant offers solutions all the way from the machine to the cutting edge, through clamping units, adaptors and holders – empowered of course by dedicated insert geometries.
