Aug. 13, 2014 – Enerpac has announced its upgraded Collet-Lok family of hydraulic workholding with “Depressurized Holding Technology.” Designed to protect against unintentional loss of clamping, Collet-Lok requires no hydraulics to maintain clamping force. Compared to traditional workholding, which requires continuous hydraulic pressure, Enerpac Collet-Lok uses an internal mechanical locking system to maintain the clamping force—automatically, without hydraulic pressure, indefinitely.
To satisfy diverse workholding applications, Enerpac has improved its Collet-Lok product family through the following:
Standard Viton seals for better performance in high temperature applications and enhanced chemical resistance to common coolants.
Bottom flange models come standard with dual porting built-in, bottom and side ports, allowing flexible installation options.
Quick lead-time response capability for the complete range of standard Collet-Lok products.
“Loss of clamping force during machining can be costly—from scraped parts to machine damage and downtime. Anyone involved in the industry knows this can occur,” said Douglas Lacina, Global Marketing & Engineering Leader for Enerpac. “With the automation of hydraulic actuation, combined with the security of an internal locking mechanism, Collet-Lok ensures continuous clamping and support, even if a hydraulic line is accidentally cut during machining. Plus, with an upgraded design and fast availability, Collet-Lok is ideal for our customers’ diverse machining requirements.”
The Collet-Lok family of hydraulic workholding products includes swing clamps, work supports and push cylinders. Available in multiple sizes and mounting methods, Collet-Lok provides all the clamping products needed for typical fixture applications.
