Chucks

Chucks comprise a category of universal holding devices used in turning applications, capable of interior diameter or outer diameter (ID or OD) clamping. Chucks feature two to eight jaws, catered to fit the shape of the workpiece. Lathe chucks can be mounted vertically, horizontally, or inverted, and are operated either manually, electrically, hydraulically, or pneumatically. Along with standard jawed chucks, magnetic, electrostatic, and vacuum chucks also exist for custom applications.

How to Pull Off Tough Machining Jobs Without Pulling Out

With Video

By using special drive keys in the tool holder that perfectly match the spiral-shaped grooves on the cutting tool shank to create frictional clamping forces and a positive locking form-fit, the Safe-Lock system from Haimer effectively prevents the cutting tool from pulling out of the tool holder, increases the productivity through faster permissible speeds, and increases tool life.

Modernizing the Standard for Balancing Tools and Tool Systems

Did you realize that the G2.5 balance specification in ISO 1940-1 is no longer practical, technically possible or economically feasible in today’s advanced manufacturing environment? Here’s the good news: A new standard is now being developed that applies to all of today’s relevant variables for safe and productive machining. Say hello to ISO 16084.

Did you realize that the G2.5 balance specification in ISO 1940-1 is...

Time to Reconsider Holding Taps with Collet Chucks

With Video

The next time you think about setting up a tapping operation with a collet chuck the same old way you always have, you may want to think again. There are now tap holders designed specifically to mitigate the load imposed on the tap by essentially absorbing synchronization error.
