Spannzange Typ ER 32/470 E – ER 32 collet, 5 mm clamping diameter, TECWERK

Spannzange Typ ER 32/470 E is a precision ER 32 collet designed for secure tool holding in ER collet chucks, suitable for machining tasks that demand repeatable concentricity and simple integration into standard toolholding systems

• ER 32 system compatibility
• Accurate runout: 5 µm
• Full-length tool retention
• Clamping diameter 5 mm

Reliable high-precision clamping for consistent machining

The ER 32 collet delivers measurable benefits for production environments: a 5 µm runout and defined clamping diameter ensure components remain within tight tolerances, reducing scrap and rework. Compliance with DIN 6499-B confirms compatibility with standard ER collet chucks, making integration straightforward. Runout (total indicated runout) describes concentricity of the clamped shank; the lower the value, the less radial deviation during rotation, which translates into improved surface finish and longer tool life. This objective performance characteristic supports predictable process control and quality assurance in serial production.

Secure retention over the full clamping length improves stability

Designed to hold tools along their entire clamping length, this collet enables more stable machining and lower vibration levels, which benefits both surface quality and tool service life. The full-length retention capability means cutting tools and extensions are supported closer to the spindle, reducing bending moments. Dimensional references such as L: 40 mm, d: 5 mm and D: 33 mm describe the collet’s geometry and help plan toolset-up and interference checks. The capacity to clamp on the pilot chamfer increases adaptability for non-standard shank conditions, while the bridging capacity (nominal minus 1.0 mm) allows secure clamping of reduced-diameter shanks without intermediate adaptors.

Streamlined workshop logistics and fast changeovers

Because intermediate sizes are not required and the collet fits standard ER 32 tooling systems, stockkeeping is simplified and changeover times are reduced. The combination of system compatibility and predictable retention performance supports lean workflows and fewer setup errors. For operations aiming to balance efficiency with precision, the standardised interface and repeatable clamping behaviour enable straightforward tool exchanges and calibration routines. Access to a comprehensive range of matching accessories via a trusted distributor further reduces downtime and helps maintain continuous production.

FAQ

Is this collet compatible with standard ER 32 chucks?
Yes. The TECWERK ER 32 collet is manufactured to match DIN 6499-B interfaces and is compatible with standard ER 32 collet chucks for straightforward integration.

What runout performance can be expected with this collet?
The collet offers a runout and repeatability of 5 µm, which supports high-precision machining and consistent concentricity for rotational tooling.

Can the collet hold tools with slightly reduced diameters?
Yes. The collet provides a bridging capacity of nominal minus 1.0 mm, allowing secure clamping of shanks that are undersized relative to the nominal diameter.

What are the main dimensions to consider for tool set-up?
Key dimensions: L: 40 mm, d: 5 mm, D: 33 mm—these values assist in fixture planning and ensuring adequate clearance in the toolholder assembly.
