Universal stepped jaws reversible, with three ground clamping stages and threaded mounting hole for fixed stop. The hardened and ground jaws are used for clamping of finished parts or in the second setup. Material Steel Finish Hardened, grinded Scope of delivery 2 Reversible stepped jaws

For form fit clamping of raw material. The hardened surface of the grip jaws deforms the workpiece surface during the clamping process and thus increases the holding force of the clamping location. Material Special tool steel Finish Hardened Scope of delivery 2 Stepped grip jaws Practical advice The stepped grip jaws are especially suitable for large clamping width. Best results with workpieces up to 1100 N/mm2 material strength and sturdy material surface.

For form fit clamping of raw material. The carbide grip-inserts of the clamping jaws deform the workpiece surface during the clamping process and thus increases the holding force of the clamping location. The grip inserts can be replaced, if necessary. Material Steel, carbide (grip inserts) Finish Hardened, grinded Scope of delivery 2 Reversible stepped jaws with carbide grip inserts Practical advice Best results with workpieces with more than 1100 N/mm2 material strength and sturdy material surface.

The pendulum jaws with grip inserts allow raw material clamping of cast, molded as well as unparallel sawed and round workpieces. With the pendulum jaws, angular misalignments of several millimetres can be rectified. The applied coating protects the grip inserts from premature wear. The grip inserts can be flexibly mounted on the pendulum jaws and replaced if necessary. Material Steel Finish Hardened, grinded and coated (grip inserts) Scope of delivery 2 Pendulum jaws with grip inserts Practical advice Best results with workpieces up to 1100 N/mm2 material strength.

Universal stepped jaws reversible, with integrated grip inserts, ground clamping stages and threaded mounting hole for fixed stop. For form fit clamping of raw material or for clamping of finished parts on the smooth clamping stage. The hardened surface of the grip inserts deforms the workpiece surface during the clamping process and thus increases the holding force of the clamping location. The applied coating protects the grip inserts from premature wear. The grip inserts can be replaced, if necessary. Material Steel Finish Hardened, grinded and coated (grip inserts) Scope of delivery 2 Reversible stepped jaws with grip inserts Practical advice Best results with workpieces up to 1100 N/mm2 material strength.

Universal stepped jaws reversible, with integrated clamping inserts, ground clamping stages and threaded mounting hole for fixed stop. The clamping insert can be mounted on the reversible steped jaws depending on the application. For clamping of finished parts there is also a smooth clamping stage included. The clamping inserts can be replaced, if necessary. Material Steel Finish Hardened, grinded and coated / carbide coated Scope of delivery 2 Reversible stepped jaws with clamping inserts 1. Side For form fit clamping of high-strength raw material. The hardened and coated surface of the clamping jaws deforms the work-piece surface during the clamping process and thus increases the holding force of the clamping location. Practical advice Best results with workpieces with more than 1100 N/mm2 material strength and sturdy material surface. 2. Side For clamping of grinded material. High holding force through increased friction factor. The workpiece surface will not be damaged. Practical advice Best results with workpieces in mold and die production. 1,5 – 2,0 times higher friction factor or holding force than smooth clamping surfaces.

For use together with all standard jaws type MZS B as well as customer designed jaws in the mechanical centre-clamping vise MZC. Material Steel Finish Hardened, grinded Scope of delivery 2 Adapter jaws for use together with all standard jaws type MZS B

The jaws allow the quick and exact form fitted clamping of almost every workpiece contour. Shape-specific clamping jaws can be created within seconds. For this purpose, axially adjustable pins are attached to the workpiece contour and thus form a form fit to the workpiece. The secondary effect of the resulting molding element is a reduction of the actually required clamping forces through a form fitted clamping. Strong Points Clamping complex geometries Suitable for high-performance cutting Clamping process The actual clamping process is effected mechanically by means of a mechanical centre clamping vise (optional pneumatic, hydraulic or electromechanical possible). The axial movement of the pins is stepless. The clamping of the pins in your workpiece specific position is done centrally, by means of hydraulics. Fields of application Single-part / small series production Sample and prototype manufacturing Clamping from outside to inside (external clamping) Material Steel Finish Hardened, grinded Scope of delivery 2 Pin jaws including adapter

The base cubes can be inserted directly as basic elements on the machining table or can be positioned and screwed on a base plate. They shorten the Z-movement of the machining spindle during the process or enables the non-collision use of short tools. Material Steel Finish Sand-blasted, grinded Scope of delivery 1 Base cube 2 Centering bolts for centre-clamping vise 1 Set fixing screws for centre-clamping vise or compact vise Note Mounting material for machine table upon request.

The work locators can be fastened to the centre-clamping vises, compact vise and several clamping devices. Material Steel Finish Black-finished Scope of delivery 1 Work locator

The different side clamps are used to fix the mechanical centre-clamping vises and compact vises. They have been specially designed for grid plates with SPREITZER grid hole system 20-M10. Fixing material for T-nut 14 mm Material Steel Finish Black-finished Scope of delivery 1 Side clamp

Sets for fastening the mechanical centre-clamping vises or compact vises on T-slot 12 mm, 14 mm resp. 18 mm. Material Steel Finish Surface hardened sand-blasted Scope of delivery 4 Single clamping claws 4 Slot nuts 4 Allan screws 2 Center bolts

Wrenches with ratchet function for manual operation of centre-clamping vises and clamping tools.

Movable center jaws for centre-clamping vises. For clamping of two workpieces. The soft version can be machined and fitted on the workpiece. Material Steel Finish Soft Optional hardened with removable clamping jaws, hardened with grip (for MZR) Scope of delivery 1 Center jaw with mounting rails Practical advice By the movable design two different sized workpieces can be clamped in the centre-clamping vise.

The centre-clamping vise series MZC is characterized by a massive and torsion-free construction. The large clamping width and the high clamping force enable the universal and flexible use on multi-axis machining centres. Due to the optimized and compact design as well as the wide range of clamping jaw types an optimal accessibility to the workpiece for different customer needs respectively an optimal accessibility on different machine concepts can be reached. Strong Points First and second setup in the highest quality Unmachined and pre-machined workpieces High clamping and holding force 100% encapsulated design Fields of application Single-part / small series production High quality milling, HPC Clamping from outside to inside (external clamping) Clamping from inside to outside (internal clamping) Material Tempered tool steel Finish Surface hardened Functional surfaces precision grinded Hardened spindle (Type E) Hardened and grinded spindle (Type S) Ground in and clearance-free adjusted base jaws Scope of delivery 1 Centre-clamping vise with operating instructions 1 Pair reversible stepped jaws Accuracy MZC type E Centering accuracy ±0,015 mm* Repetition accuracy 0,01 mm Pairing accuracy 0,01 mm MZC type S Centering accuracy ±0,005 mm* Repetition accuracy 0,003 mm Pairing accuracy 0,01 mm * to the alignment holes on the bottom side Practical advice Sealing air connection If necessary, additional sealing air offers protection against the permeation of coolants and dirt.
