Clamping heads . Clamping heads SPANNTOP 4 . 1 . 2

Technology proven in practice

clamping heads This development represents more than 20 years of SPANNTOP experience and it exploits all the advantages of the latest machine tools. The clamping head is not only extremely powerful, it is also convincing through simple handling. Set-up in no t ime at all with the changing fi xture. The combinat ion of steel and rubber, com-bined through a high-quality vulcanizat ion process, is designed for maximum RPM and holding power – with opt imum concen-tricity, extreme rigidity and long life. Naturally there have been a number of improvements over the years to ensure reliability on this mature technology.

Key advantages Concentric precision < 0.01 mm possible

Typical HAINBUCH features, such as user friendly set-up, full passage, parallel clamping, opt imal power conversion, extreme rigidity and superior holding power, as well as minimal wear and tear

The clamping head

The solid clamping head is precision

ground in one set-up. It is then separ-

ated into segments and re-joined to its

intended diameter through the vulcani-

zation process. We have perfected

this technology – you will notice the

dif-ference. It takes lots of expertise

and meticulous work to join these stiff,

hardened chrome-nickel segments

with the especially for this purpose

developed rubber from HAINBUCH.

That rubber is resistant to all standard

coolants and it prevents chips from

entering the chuck.

Machining of HSW clamping heads

Vulcanized clamping heads of

various standard sizes in round,

serrated and smooth versions are

usually available from stock – as

are most of the standard size

hexagon and square profiles.

clamping head

For raw material:

Standard design

■ Serrated

■ Z or F serration for heavy-duty

cutting

For precision machining:

G design

■ Smooth clamping bore

For ultra precise machining:

Soft jaw HSW design

■ Only the taper and coupling areas

are hardened while the ID and face

of the clamping head are soft.

By clamping a loading ring or plug,

the HSW head can be machined to

the required size.

Available options:

■ No axial grooves

■ Reduced face slot width
