Spindle Tooling for Manual & CNC Lathes
This document provides comprehensive information on Hardinge's workholding solutions, focusing on collets, feed fingers, and pads for manual and CNC lathes. It highlights the significance of material quality and heat treatment processes to ensure durability and performance.
- Hardness and Durability: Hardinge collets are 5 to 7 points harder on the Rockwell "C" scale than competitors, ensuring longer life and reduced downtime.
- Concentricity Inspection: Collets are inspected for Total Indicator Runout (TIR) using a Hardinge Super-Precision® spindle, ensuring standard collets run at .0005" or better.
- Collets: Available in various sizes and shapes, including 5C, 16C, 20C, 25C, and 3J, with options for special accuracy and emergency collets.
- Step Collets: Designed for use with Hardinge threaded positive stops, available in 5C-SC and 16C-SC types.
- Extended-Nose Collets: Allow for deeper counter-bores and tool clearance, available in both standard and emergency versions.
Hardinge emphasizes the value of their workholding solutions in terms of product longevity, machine uptime, and workpiece accuracy. The company has a long history of manufacturing precision workholding products, ensuring high standards of quality and reliability.
Hardinge's collets and workholding solutions are suitable for gripping various materials such as metals, wood, plastic, and glass, and are used in diverse applications including holding pins, electronic components, and more.
The document includes detailed tables with dimensions, capacities, and part numbers for various collet types, as well as safety information and frequently asked questions.
The document lists emergency collets for different models such as 3C, 5C, 16C, 20C, and 3J, with specific part numbers, sizes, and lengths. Emergency collets are available with different slot configurations and materials, including steel and brass.
These collets are designed for specific applications requiring extended reach, with part numbers and specifications for both 3C and 5C models.
Specifications for male center headstock centers are provided, including dimensions and part numbers for 5C, 16C, 20C, and 25C models.
These collets have a longer bearing surface and are available in letter, number, fractional, and metric sizes. They do not have internal stop threads.
These collets are available in different split configurations and are used for precise lens-making applications.
The document details regular and extra-depth step chucks, including their sizes, materials, and part numbers. It emphasizes the importance of using closers for rotating applications to ensure safety and accuracy.
Information on Kellenberger adapter and collets for grinding applications is provided, along with details on 5C extra-depth step chucks and closers.
The document includes cautionary notes about the necessity of using closers for rotating step chuck applications and provides part numbers for replacement pins and spanner wrenches.
These collets require a limit ring and are designed for a gripping range of 0.562" to 0.750". They offer advantages such as instant centering, quick changeover, wide gripping range, and high gripping force. They also feature a built-in safety stop to prevent overexpansion and ensure exact part length control.
Collet adapters allow the use of smaller collets in machines with larger collet seats. They are available for adapting 5C collets to 16C spindles, 16C collets to 20C and 25C spindles, and 16C step chucks to 20C spindles. These adapters are not recommended for precision work due to potential TIR issues.
These adapters use the lathe’s standard closer with the adapted step chuck and are available for various spindle sizes. They include components like draw tube adapters, reducer bushings, and mounting bolts.
These are used to hold parts with a stem and locating shoulder, allowing for accurate length control even with varying gripping diameters. They provide stability for longer parts and are cost-effective for precision length control.
Fixture plates are used for mounting parts that cannot be held in standard collets or chucks. They are custom-designed and must be balanced for safe operation. Available in spindle-mounted and collet-style for 5C and 16C spindles.
Available in 5/8" and 1/2" shaft diameters, these arbors are used for simple milling operations on mills with a 5C spindle.
These racks protect collets and provide easy access and selection. They are available in different capacities and can be bolted to work tables for stability.
Hardinge offers custom manufacturing of special collets and step chucks for unique workholding applications. They provide technical assistance for designing these devices to meet specific machining needs.
- SE Ejector Stop for B&S Collets: The ejector stop assembly is threaded into the back of the collet, with the insert machined to locate the part. Collets are sold separately.
- Stationary Collet Systems: Designed for dead-length applications on lathes with A-5 spindle noses. Separate link-ups are required for other lathes. Part numbers and assembly details are provided.
- A-5 16C Spindle to B&S Collet Adaptation Chuck: Specifications include spindle length, flange OD, nose OD, and thru-capacity.
- GT 5C to #11 B&S Collet Adaptation Chuck: Detailed dimensions and part numbers are provided for assembly.
Dimensions for various collet types, including solid collets and stop collets, are listed with part numbers and rated capacities.
- Face Plates and Fixture Plates: Maximum surface speed is 6000 fpm, with rpm recommendations provided for different fixture plates and jaw chucks.
- Manual Jaw Chucks: Available for manual machines with Hardinge 5C Spindles. Part numbers for various chuck types are included.
A comprehensive list of machine manufacturers and corresponding collet types is provided for reference.
Dimensions and rated capacities for different collet styles are detailed, including part numbers and thread specifications.
This document provides technical guidance on the use of various spindle tooling systems for lathes, mills, and other machinery, with a focus on Hardinge products. It includes frequently asked questions and procedures for specific tooling operations.
- Stop Plate Usage: A stop plate is recommended with the Sure-Grip Expanding Collet to prevent movement and stabilize the part during heavy stock removal.
- Emergency Collet Boring Procedure: Insert the collet with the draw bar fully open, ensure pins are in place, adjust the collet closer, and lock the draw bar. Adjust chucking force appropriately and finish the bore to the required diameter.
- Custom Tooling: For parts with larger chucking diameters than standard offerings, custom spindle tooling is available to accommodate specific needs.

A hardened and ground collet has a head angle and bore that are case hardened to 60 to 63 Rockwell. This will give you the maximum life possible. The bore is precision ground and guaranteed to have a TIR of .001" or less. Special-accuracy collets are available that are guaranteed to have a TIR of .0002". Before investing in a special-accuracy collet, check your standard collet Ζ they usually have a TIR of .0005" or better. All draw-in collets have a diameter-to-length ratio when doing secondary operations. When using 5C, 16C, 20C, 25C collets or other collets with a 10 head angle, the ratio is...
