The RINGSPANN idea

RINGSPANN has been developing and manu-facturing Precision Clamping Fixtures for work-holding applications for over 70 years. Over thepast decades we have realized thousands of ap-plications and numerous technically sophisti-cated solutions.

RINGSPANN specialized in clamping and cent-ring on cylindrical internal and external surfa-ces. Typical components include automobile,gear and aircraft components.

We have developed the RINGSPANN system onthe basis of the RINGSPANN Clamping Disc,which encompasses

• Complete Clamping Fixtures, ready-to-use,

• Clamping Elements and components forcustomer assembled Clamping Fixtures and

• Clamping Principles for custom ClampingFixtures.

The RINGSPANN system offers the right solutionfor each clamping application and guaranteesmaximum clamping precision without the needfor complicated alignment. This enables custo-mers to achieve difficult objectives, such asclamping in short lengths or clamping thin-walled components that are susceptible to deformation.

The basis of the RINGSPANN system is theRINGSPANN Clamping Disc, a flat-taperedring made of special hardened spring steel.The characteristic slotting provides for espe-cially high elasticity.

The axial actuating force causes an elasticchange in the taper angle and thus alters thediameter of the Clamping Disc. If its insidediameter is supported by a mandrel, the out-side diameter expands. If the outside diame-ter of the Clamping Disc is supported, theinside diameter decreases.

Especially advantageous is the so-calledRINGSPANN effect. The initiated actuatingforce is transposed friction-free into a radialforce that is 5 to 10 times higher, which isthen used to clamp the component.

The actuating force simultaneously induces atipping movement of the Clamping Disc. Thismovement is used to press the componentagainst a longitudinal backstop during clam-ping.

Mounted on a mandrel, the Clamping Discengages the entire inside circumference ofthe component bore. The radial forces pro-duce a frictional connection between theClamping Disc and the component.

The uniform application of force to the entirecircumference of the component guaranteesmaximum clamping precision and permitsthe transmission of higher torques, even incontact with elastic components that aresusceptible to deformation.

Similarly, the cylindrical outside surfaces ofthe component are clamped by a ClampingDisc seated in a chuck.

Short clamping lengthsThe RINGSPANN system permitsshort clamping lengths with hightorque transmission.

Extended insertion depthsThe RINGSPANN system supportsextended insertion depths withhigh torque transmission.

No deformationThe thinner-walled a workpiece is,the more sensitive to deformationit becomes. A three-jaw chuck canno longer be used economicallywith such workpieces, since theclamping forces must be reduced toa level that ensures it doesn’t causeany impermissible deformation.This inevitably leads to a reductionof the cutting data and thus an in-crease in the impact duration. UsingRINGSPANN Clamping Fixtures,workpieces are gripped over theirentire circumference. It is thus pos-

High true running accuracy True running accuracy of ≤ 0,01 mmis attainable.

Extended insertion depth

Short clamping fixture length

Clamping Fixtures based on theRINGSPANN system ensure mini-mum spindle overhang and thushigh spindle rigidity and precision.
