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.
Companies concerned about strict quality requirements regularly check toolholder tapers for wear or inaccuracy because these conditions can jeopardize the results of a critical operation. However, a shop can check tapers quickly and reliably with air gages. These devices can be used effectively without special operator training. For measuring taper in a production environment, few other methods can match the speed and performance of air, as multiple-circuit air jets can be placed in very small taper gages.
Angle heads can enable a three-axis machine tool to be more versatile. That said, this shop explains that there’s more to getting started using them than simply loading them into a machine’s spindle.
