Vargus USA's ALCN External Thread Turning Toolholders Provide High-Pressure Coolant
IMTS Spark: Vargus USA’s ALCN line of external thread turning toolholders with high-pressure coolant is designed for improved productivity and extended tool life.
Vargus USA’s ALCN line of external thread turning toolholders with high-pressure coolant is designed for improved productivity and extended tool life. The toolholder features two precise high-pressure coolant outlets that cool down the top and bottom of the insert. The outlets are designed for high-pressure coolant ranging to 70 bar. With accurate coolant delivery, the cutting edge temperature is dramatically reduced, thereby increasing tool life. Additionally, the coolant through function improves chip evacuation for better chip control and flow.
The toolholder also features three coolant inlets. One bottom inlet and the back inlet are designed for standard screw connection. A second bottom inlet is designed for VDI Holder according to DIN 69880/ISO 10889.
These toolholders are available for Vardex standard lay-down insert sizes, including 3/8", 1/2" and 5/8", and are also offered in metric and inch shanks. Left-hand toolholders are available as standard. A nickel coating improves wear resistance and corrosion protection.
The retention knob is an unmistakably critical component of the machining process. However, the tightening of the knob itself can lead to the toolholder not seating securely in the machine. You may be losing tool life to knob tightness without even knowing it.
A system to be marketed in 2015 will apply ultrasonic vibration from within the toolholder to reduce cutting force and improve the performance of the cut.
Horn USA has developed quick-change tooling systems to drastically reduce set-up and toolchange times for Swiss-type lathes, including those with through coolant.
