Vardex Threading Toolholders Offer Two Coolant Ports
Vardex external thread turning toolholders have two high-pressure coolant outlets for greater precision and longer tool life.
Vargus USA’s ALCN line of external thread turning toolholders feature two precise, high-pressure coolant outlets designed to cool the top and bottom of the insert for longer tool life, and are specially manufactured for high-pressure coolant (up to 70 Bar). According to the company, when used with a quality coolant, the cutting-edge temperature is dramatically reduced, thereby increasing tool life. Also, the through-coolant capability improves chip evacuation for better chip control and flow, and enhanced productivity.
The new toolholders also feature three coolant inlets, suitable for some of the most popular machines on the market, including a bottom inlet designed for standard screw connection;
a bottom inlet specially designed for VDI Holder according DIN 69880/ISO 10889; and a back inlet designed for standard screw connection. The toolholders are available for Vardex standard lay-down insert sizes: 3/8", 1/2" and 5/8", and are offered in metric and inch shanks. Additionally, the new range also offers left hand toolholders as standard. All new toolholders are nickel-coated for better wear resistance and anti-corrosion protection. The new toolholders are integrated into the Vargus Genius software for tool selection and accessing suggested cutting data.
CNC Swiss-Type machines have more capability built in than ever before. Many of these capabilites can be accessed using attachments that increase the throughput of the machine tool, improve the quality of the work coming off the machine and reduce or eliminate the need for secondary operations even for very complex workpieces.
An ongoing effort towards more efficient operations drove this shop to take a closer look at indirect material usage, subsequently leading to implementation of a new system for tracking toolroom inventory.
Workholding for turning is usually fairly basic: The selection comes down to chucks or collets. This article looks at when to consider the collet chuck and what kind might be best for a given application.
