Collet-Lok workholding range upgraded

ENERPAC  has introduced into the market an upgraded version Collet-Lok? family of hydraulic workholding that incorporates  Depressurized Holding Technology?. Collet-Lok requires no hydraulics to maintain clamping force.

The hydraulic workholding product range includes swing clamps, work supports and push cylinders. Available in multiple sizes and mounting methods, they provide all the clamping products needed for typical fixture applications.

Compared to traditional workholding, which requires continuous hydraulic pressure, the range uses an internal mechanical locking system to maintain the clamping force -- automatically, without hydraulic pressure, indefinitely.

“Loss of clamping force during machining can be costly, from scraped parts to machine damage and downtime.” said Douglas Lacina, Global Marketing & Engineering leader for Enerpac. “Anyone involved in the industry knows this can occur.”

Enerpac has improved its Collet-Lok product family to protect against unintentional loss of clamping and satisfy diverse workholding applications.

• Standard Viton seals assure 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.

The automation of hydraulic actuation combined with the security of an internal locking mechanism 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,” said Mr. Lacina. Additionally, Enerpac is offering Collet-Lok webinar classes on August 18, and has produced an informational video to help customers understand Collet-Lok further.
