F77 Spacer Sleeve CompensationDisc Without Spacer Sleeve (with c`bored hole) . . . . With Spacer Sleeve (with straight hole) . . . . Description: The preloaded Combination Spring- and Spacer Unit combines the functions of providing the spring force and of spacing the stripper in one constructional element, whilst conventional designs employed two. The resulting advantages therefore consist of space savings and reduced machining cost with regard to the various die members. The execution with spacer sleeve makes it possible to exchange the whole unit by simply removing the top clamping plate. Removal of the compensation disc gives unim- peded access to the punches – for the purpose of sharpening/grinding. Important Notice: Regrinding of stamp in mm = regrinding of spacer. This means that the spring force and displacement always remain exactly the same. Helical compression springs must be ordered separately, see at the beginning of chapter F. 244.20. 244.25. 244.32. 244.40.
