Using knowledge gained in over 65 years of designing and manufacturing workholding products, we have developed a new quick change workholding system: Craftsman Capto™ Workholding.

Craftsman Capto™ Workholding is a modular system designed for high precision applications in milling, turning, grinding and quality inspection. Extensive modularity and vastly reduced set-up times mean that Craftsman Capto™ Workholding particularly lends itself to operations requiring frequent interchanging of the workpiece.

Flexible with extensive modularity• Extremely high basic stability and accuracy• Dramatically reduced set-up time• Extensive customisation available• Resists 120-4000 Nm torque and 100-1700 Nm of bending moments • (depending on size)Balanced and self-centering• ISO 26623• Available in six sizes (C3, C4, C5, C6, C8, C10) to cover the majority of • applications

OVERVIEW

BENEFITSAPPLICATIONS

Select the interchangeable workholding element and insert the Craftsman Capto™ end into the base unit.

Actuate the clamping mechanism by turning the internal hexagon using a wrench and specified torque. The Craftsman Capto™ system centralises and draws the workholding to the datum face. Apply the same process in reverse to unclamp.

For some automated applications we recommend pre-clamping the component off the machine tool or CMM to further minimise machine downtime, or to retain relationships between different machine tools.

This is particularly effective when using expanding mandrels and automated loading (robotic arms). This enables seamless, unmanned changeover of different components, while retaining concentric relationships.

PRE-CLAMPING COMPONENTS

Change over workholding in seconds, not minutes.

BASE TYPES

SPINDLE NOSE MOUNT - MANUAL

SPINDLE NOSE MOUNT - HYDRAULIC

Mounted onto the spindle, replacing the standard machine chuck. Simple, direct, repeatable manual loading.

Mounted onto the spindle. Automated clamp/unclamp integrated with machine hydraulics. Suitable for automated loading.

MILLING TABLE ROTARY TABLE / 4TH AXIS

SPINDLE NOSE MOUNT- DRAWBAR

Clamping directly to milling table. Can be used with multiple units in tandem and with base offset to specified angle.

Mounting directly to the face plate of a rotary table/4th axis.

Mounted onto the spindle. Automated clamp/unclamp integrated with machine drawbar. Suitable for automated loading.

FACE PLATECan be produced with a specified arrangement of bolt holes and location features. Suitable for mounting to fixture plates or cubes.

CHUCK JAWSTwo piece assembly allows for minor adjustments to ensure repeating concentricity of workholding. Grip using soft jaws.

MAGNETIC CHUCKLarge ground plate mounts to magnetic chuck. Once set concentrically, repeatable quick changing of workholding is ensured.

NOTE

Most base types shown are manual by default, but are also available as hydraulically actuated versions for automated application.

INTERCHANGING ELEMENTS

THREAD ACTUATED EXPANDING MANDREL

CANTILEVER NUT ACTUATED EXPANDING MANDREL

For optimum internal gripping of cylindrical parts. Sleeve energised using a threaded nut on the front of the mandrel.

For optimum internal gripping of cyclindrical parts. Suitable when there is no access for hand tools from the front of the component.

COLLET CHUCK BORING BAR HOLDER

TAILSTOCK ACTUATED EXPANDING MANDREL

FACE PLATE

For optimum external gripping of cylindrical parts. Sleeve energised using a threaded nut on the front of the collet.

For optimum external gripping on boring bar tools with minimum vibration. Can also be used to hold long shaft-type components.

For optimum internal gripping of cylindrical parts. Suitable for components where only a short grip length is available.

Suitable for holding cylindrical and non-cylindrical parts through an arrangement of clamps and locating features.

CHUCK JAWS

For internal and external gripping of cylindrical parts. Large grip range, but not as accurate as a collet or mandrel.

STATIC SLEEVEEXPANDING MANDREL

For optimum internal gripping of cylindrical parts. Suitable for components where only a short grip length is available.

ROTATING CENTRE

For centre support. Also available in static (non-driven) form, and with variations of centre spindles.

1. Cantilever nut-operated expanding mandrel. Craftsman Capto™ workholding interchanging with a vertical milling machine for 4-axis machining of dye components.

2. Craftsman Tools’ rotating centre adapted for a Craftsman Capto™ base unit that mounts directly to a magnetic chuck for high precision grinding. A much quicker alternative to changing over the magnetic chuck.

3. Small diameter thread-actuated expanding mandrel used for machining of composite components for aerospace applications. The Craftsman Capto™ base is designed to be held in soft jaws on a lathe and then adjusted to run exactly true (concentric). The base can then be interchanged with multiple sizes of mandrels.

4. Craftsman Capto™ workholding mounted directly to a 4th axis rotary table on a vertical milling machine. The system also includes a Craftsman Tools adjustable tailstock. The Craftsman Capto™ Workholding can be interchanged with mandrels, chuck jaws, centres, etc.

5. Range of large diameter collet chucks with a Craftsman Capto™ C8 back end. Used in inspection processes for checking the range of machine cutting tools from 30 to 50mm diameter, interchanging with fixture bolting that bolts directly on to the table of the CMM.

6. Large diameter expanding mandrel (thread operated) interfacing with a Craftsman Capto™ C6 base, which is designed to bolt onto the machine table of a vertical milling machine. The expanding mandrel is also interchanged with a range of smaller expanding mandrels for this application.

7. Standard 4 jaw chuck adapted for interchanging with Craftsman Capto™ C10 base fixture, designed to bolt onto the machine table of a vertical milling machine. C10 is the largest available size of Craftsman Capto™ unit and will resist up to 4000Nm of torque and 1600 Nm of bending moments.

8. We also offer the same extensive modular range for other standard clamping systems, such as VDI (DIN 69880) and HSK. Pictured is a long, thread-operated expanding mandrel with HSK100 used to produce hydraulic cylinders.
