German term

Pflasterbacken

German to English Tech/Engineering Mechanics / Mech Engineering Clamping technology
Harte Rillenbacken, glatte Aufsatzbacken, Harte Pflasterbacken,

Procedures for calculating the cutting forces for these jaw types are specified

My thought is that Pflaster refers to the pattern on the clamping surfaces of the jaws. But I have not found anything. Your help is appreciated.

The jaw types cited are used to clamp workpieces for lathing and milling, metal cutting. CNC machining is the application area.

The Multi-Stone Grab S400-P became a multifunctional tool over the years as a result of the growing assortment of exchangeable gripping jaws: Simple to change and without tools done only in a fec seconds.
Equipped with the slab gripping jaws, this grab is becoming a much-asked-for slab laying clamp.

Multifunctionality is high up on the agenda. The adavantage is clear: Higher return on investment.

The idea of exchangeable gripping jaws has been realised first in 2003 with the prototype unit of Multi-Stone Grab S400-P. In these former years only availabe for laying kerbs and block steps, the gripping jaw assortment grew over the years. The close contact with the market always again brought up new applications: Turfstones, L-shaped retaining wall elements, foundlings, quarrystones, gutter stones, border stones, pavers in layers and last but not least big-sized pavers or slabs.

In combination with the slab gripping jaws, slabs of all sizes and materials can be installed either in close contact or with gap - independently of its surface. The transportation of pavers is another application for this slab jaw.

Slab jaws are available for both models, S100-P and S400-P.

The following application illustrates the laying of slabs with dimension 50/25/10 with the S400-P and the slab gripping jaw on a site with 10.000sqm. Here three of this slabs are picked up and installed at once.

Info

I think Pflasterverzahnung, rubber and serrated are the key words here.

Rubberflex® RFC3612/R Spannzange 11 - 13 mm, Full-Grip
Profitieren Sie vom großen Spannbereich der Rubber-Flex® RFC Spannzangen. Die elastische Gummi-Metall Verbindung ermöglicht einen Spannbereich von ± 1 mm zum Nenndurchmesser. So sparen Sie nicht nur die Investition in vier zusätzliche Stahlspannzangen sondern reduzieren auch deutlich Ihre Rüstzeiten. Durch die „Full-Grip“ Pflasterverzahnung mit Längs- und Querrillen wird die Spannkraft deutlich erhöht.

Benefit from the large clamping range of the Rubber-Flex® RFC collets. The elastic rubber-metal conjunction allows a clamping range of ± 1 mm to the nominal diameter. So you safe not only the investment in four additional steel collets but you are also reducing your changeover times. Furthermore these double-serrated collets have an increased clamping force and are especially designed to machine bar material with wide clamping tolerances and high torque.
