The solution

GrindTec: innovation in grinding

There is an alternative to the traditional magnetic chuck for parallel pole grinding: GrindTec. The surface is 100% metallic, with round poles machined from a single piece via core drilling. There is no joining element: the area in contact with the piece is robust and impenetrable, reliable and long-lasting.

GrindTec is bidirectional and uses circular pole geometry: each pole generates a constant workholding force of 150 kg. Thanks to special mobile pole extensions it is possible to automatically shim workpieces.

GrindTec is equipped with the patented “NUFLUX” system, for complete elimination of magnetic residue from the workpiece, even with alloy steel. Designed for pieces with thicknesses starting from 5 mm, GrindTec is available in various sizes, rectangular or circular shapes and is suitable for all types of machines.

Advantages

Maximum level of safety
Energy saving
No overheating
No deformation

MONO-BLOCK STRUCTURE

All GrindTec grinding series permanent-electro magnetic chucks have a mono-block frame of reduced thickness in order to lighten the load on the machine to improve performance and reduce wear.

The total rigidity of the system and absence of deformations over time are the main characteristics associated with magnetic configurations with different pole pitches to be chosen depending on the type of machine. During the entire machining phase the electrical power supply is cut without any electrical current circulating inside.

UNIFORM WORKHOLDING

A series of through holes placed in relation to the centre distance of the slots on the machine bed allows for easy installation. Multiple modules can be placed side by side to form magnetic banked panels of various sizes.

EXCLUSIVE NUFLUX SYSTEM

Control units are equipped as standard with the patented demagnetization system, “NUFLUX”, which completely eliminates any possible magnetic residue from the surface of the workpiece, even from alloy material or after heat treatment.

TFP modules

Strongly supported by our thirty years of experience in collaboration with central grinding machine manufacturers, we offer a range of models suitable for all production needs. Clamping with a permanent-electro chuck allows the piece to be held uniformly over the entire surface, reducing vibrations during machining. The permanent-electro chuck does not generate heat, therefore it does not heat or deform the piece.

Permanent-electro magnetic chucks for TFP grinding are available in different versions:

GrindTec GT

The solution for medium/large workpieces. The innovative TEC mono-block construction technique makes the “Full Metal” magnetic machining surface totally independent from the lower part which houses the AX reversible permanent magnets, the coils and all the electrical connections, acting as a mechanical shield. GrindTec GT is therefore impenetrable to coolant and processing residues, guaranteeing high reliability over time without specific maintenance.

TFP0: TRANSVERSE POLARITY

The most convenient solution. The permanent-electro chucks of the new TFP0 series are characterised by a mixed steel/resin surface. They are “universal” chucks, as they adapt perfectly to the needs of the majority of applications. They guarantee perfect holding of various types of workpieces with maximum versatility.

TFP1: TRANSVERSE POLARITY

The “Full Metal” solution, in steel and brass. The particular arrangement of the poles creates a dense mesh of magnetic “stitches”, with a reduced flow short-circuiting section (5 mm). The dense pole pitch, transversal to the machining axis, allows safe clamping, even for small and workpieces with reduced thickness. Its particular construction characteristics guarantee high resistance to wear.

TPF: ULTRA FINE TRANSVERSE POLARITY

The ultra fine “Full Metal” solution, in steel and brass. Ultra fine pole pitch suitable for very thin workpieces of reduced size. A series of multiple, closely-spaced “magnetic stitches” with a magnetic flux short-circuiting section in just 2mm of thickness.
