Product catalog summary
Overview
This document explores advanced hydraulic expansion clamping technology, focusing on its precision, efficiency, and economic advantages in machining rotationally symmetric components. It addresses the limitations of standard systems and how hydraulic expansion clamping devices overcome these challenges.
Key Features
  • High Clamping Accuracy: Achieves radial runout of less than 3 µm, ensuring precision with a wear-resistant HSS expansion sleeve.
  • High Clamping Force: Maximum force of 500 daN/cm², evenly distributed to prevent deformation.
  • Enormous Strength: High bending and torsion rigidity for maximum cutting forces, suitable for heavy machining.
  • Reliability and Longevity: Innovative design ensures a tight connection without mechanical seals, providing consistent clamping force and durability.
System SH Description
The System SH is a versatile hydraulic expansion clamping system capable of simultaneously clamping multiple workpieces, featuring an elastic expansion sleeve that expands radially by about 0.3% of the clamping diameter.
Quality Features
  • Expansion sleeve made of highly wear-resistant high-speed steel.
  • Radial runout ≤ 0.003 mm.
  • Adjustable clamping force with high-repeat accuracy.
  • High bending resistance and torsion rigidity.
  • Low-wear, dirt-resistant clamping system.
Application Examples
  • Flanged Mandrel: For balancing gearwheels with a 13 mm clamping diameter.
  • Centre Chuck: For inspecting wheel hubs with a 39 mm clamping diameter.
  • Centre Mandrel: For grinding cam contours with a 20.0105 mm clamping diameter.
  • Flanged Chuck: For grinding control pistons with a 16 mm clamping diameter.
Technical Questionnaire
Includes a questionnaire for customizing hydraulic expansion clamping devices, requesting details like workpiece dimensions, material, and machining requirements.
Contact Information
For inquiries, contact EMUGE Clamping Technology at (+49) 9123-186-230. The document includes placeholders for company details, address, contact person, phone, fax, and date.
Clamping Specifications
Outlines requirements for clamping workpieces or tools, including:
  • Clamping diameter with a maximum strain rate of 0.3%.
  • Active clamping length (Ls).
  • Runout accuracy relative to the clamping diameter.
  • Material and tolerance specifications.
Requests a drawing of the component to be clamped.
Machining and Cutting Data
Details machining processes such as turning, honing, milling, grinding, drilling, and reaming. Cutting data includes rotational speed, feed rate, and cutting depth. The workpiece must be inspected, measured, and balanced, with specific marking instructions for clamping, locating, and machining surfaces.
Clamping Device Adaptation
Information on mounting options (between centers, taper shank, flange mounting) and clamping actuation (manual or power-operated) is included. Specifies the adjustment range for clamping force and pressure, and requests sketches or drawings for clamping force initiation and any additional clamping mechanisms.
Balancing Requirements
Details on balancing the clamping device with or without the workpiece, including balance quality, nominal rotation speed, and permissible residual unbalance.
Additional Information
Requests information on the influence of heat, coolant, and other factors. Attachments required include drawings of the component, spindle head, connecting flange, and clamping force initiation.
Company Information
EMUGE-Werk Richard Glimpel GmbH & Co. KG and FRANKEN GmbH & Co. KG are listed with their respective addresses and contact details. Sales partners can be found on the EMUGE-FRANKEN website.

Messbare Fakten und Daten im Einzelnen Measurable Facts and Dates in Particular The radial runout is less than 3 µm depending on the expansion rate. The expansion sleeve manufactured from wear-resistant HSS material (the expansion rate is max. 0.3 % with regard to clamping diameter and clamping length) expands in perfect central alignment with the central axis over the entire clamping length. This is why hydraulic clamping elements achieve highest runout accuracy. High clamping force Die Spannkraft beträgt maximal 500 daN/cm2. Selbst bei dieser feinfühlig und wiederholgenau dosierbaren großen...

EMUGE Hydraulic Expansion Clamping-4

Systembeschreibung System SH System Description System SH Das wichtigste Bauteil in der Hydrodehnspanntechnik ist die elastische Dehnhülse. Über einen Spannkolben, von Hand oder maschinell betätigt, wird ein geschlossenes Hydrauliksystem unter Druck gesetzt. Dieser bewirkt eine radiale Aufweitung der Dehnhülse von ca. 0,3 % des Spanndurchmessers. Das System SH ermöglicht nicht nur das Spannen eines Bauteils, sondern auch das simultane Spannen mehrerer gleich schmaler Werkstücke. Bei Verwendung von Zwischenbüchsen können in einem gewissen Bereich auch Werkstücke mit einem anderen Durchmesser als...
