B 40.. Basic Beam
The hardened basic beams, which are fastened to the machine's base with screws, are used for the infinitely guiding and positioning of the cross beams. The Solid Jaws H 4320 are positioned in steps of 25 mm (1 ") and serve as a basis for the Clamper H 4300 and the Adapter H 4380 for the Multiholder of the Fixturing System 2000.

The beams are available with steps of 50 mm (2"). Length and hole pattern of the fastening screws is matched to the machine model in question.

H 4320 Adjustable End Stop

The adjustable end, stop is used on the basic beams for repetitive positioning of the cross beams.
Positioning and repetitive accuracy < 0.002 mm (0.00008"). The Basic Set 4000 plus contains two end stops.
Q 42.. Cross Beam
The infinitely movable cross beam, which can be clamped in any position, can only be used between two basic beams.
The cross beam can be inserted between the basic beam from the top or from the side.
The cross beam, and thus the workpiece mounted directly on it, can be adjusted by means of the two adjustment screws, which are next to the clamping screws. Larger workpieces up to 150 kg (330.69 lbs) can be clamped between the cross beams, provided with Support Plates H 4366.
To avoid collision of the lower wire nozzle with the support plates, the cross beam can be lifted or lowered by using spacer plates having a thickness of 6 mm (0.24"). Cross beams having a length of more than 600 mm (24") are delivered with a larger cross-section (36 x 85 mm (1.41 " x 3.34") instead of 30 x 60 mm (1.18" x 2.36")), to avoid sagging of the beam because of the large length.


QD 42.. Cross Beam
This cross beam can be equipped on both sides with clamping elements, it is often used as third beam between the standard cross beams.
 

Q 42 KLI Insulating and Clamping Element
(2 pcs.)
The cross beams can be insulated by exchanging the clamping elements for these insulating elements, which is an advantage in case of final finishing.
Further insulation possibilities are show on the pages 9 and 15.
H 4366 Support Plate
 Support plates are attached to the cross beams and are used for clamping larger workpieces between two cross beams. The support surface is variable from 8 mm (0.31 ") to 29 mm (1. 14").
Clamping of the workpieces is done with the clamping jaws of the Clamping Jaw Set H 2850, page 18.
Maximum load 50 kg (110.23 lbs).
