Innovations of stone processing

Saw plant for fully automated cutting of unprocessed slabs and handling of workpieces.

The machine is a movable gantry design and conceived for the use of 400 mm diameter saw blades. The main motor (P = 15 kW) is infinitely variable within a range from 1,000 to 2,000 1/min.

Sawing support
The lower part of the support can be turned electrically from 0 to 360° and, likewise electrically, swivelled from 0 to 46°. Two vacuum lifting facilities, each of a size of 500 x 600 mm, are mounted on the right and left, next to the main motor. The power developed by the overall suction surface allows to lift workpieces with weights of up to 800 kg. The differently sized vacuum panels required for workpiece lifting are activated automatically in dependence on the size of the piece to be handled. Only workpieces with widths of no less than 40 mm can be handled.

Tool measuring
Tool diameters are measured all automatically. The detected actual diameter is being transferred and added to the data stored in the control system in order to be used for the execution of the next step.

Workpiece measuring
Measuring of the actual workpiece thickness at pre-programmed points on the workpiece. The control system utilises the measured values for the execution of bevel cuts in a self-acting manner. Only this way can exactly dimensioned workpieces be produced.

Water jet device
High-pressure pump with closed internal cooling water circuit and automated sand flow monitoring.

5-axle cutting head support mounted on a pneumatically controlled extendable support. Water and abrasives are being mixed in the 5-axle-cutting head to produce an efficient cutting jet. High-pressure from the stationary pump to the jet is supplied through high-pressure pipes, which run in cable carrier systems.

Saw belt table
Made of special rubber and endued with a wearing layer in its upper part.
table size approx. 11,700 x 3,000 mm.

Movable machine for the grinding of V-grooves into facing slabs.

The machine slides and supports are welded-steel structures. The guide rails run on a steel substructure, are suited for direct mounting on industrial floors and require no foundation works. The substructure of the rail has been galvanized. The rail heads can easily be replaced. The stationary side is equipped with linear guides and ball monorail guidance systems for high working accuracy. The rail is covered by bellows. The moveable side is equipped with antifriction-bearing mounted rollers. The feed drive can be adjusted continuously. The operating speed V ranges from 0.5 to 4 m/min. A longitudinal feed path measuring system and a sensor for the detection of the workpiece starting and end points are also included in the equipment of the machine.

Work piece dimensions
work piece thickness from 3 mm up to max. 30 mm (depending on material)
minimum work piece width for clamping: 300 mm
work pieces with length from approx. 300 mm up to 3.600 mm could be processed.

V-groove milling units

The three V-groove milling supports can, independent of each other, be motor-adjusted in vertical direction. Each of the three main drive motors has a driving power of 15 kW and can separately be adjusted in a continuous manner. The option to adjust the milling supports, which have all been mounted on a joint base plate, in lateral direction (position freely selectable within a range from 20 up to 150 mm) is another integrated feature.

Movable edge grinding and polishing machine for the production of polished upper and lower chamfers and for the calibration of the lower edges of engineered stone, granite or marble facing slabs to a constant height.

The machine slide is a welded-steel structure. The guide rails run on a steel substructure, are suited for direct mounting on industrial floors and require no foundation works.

- 3 upper chamfering tool slides
- 2 lower chamfering tool slides
- 1 calibrating tool slide

Work piece dimensions
work piece thickness from 10 up to 30 mm
effective grinding length approx. 3,200 mm.
minimum work piece width for clamping: 300 mm
maximum heigth of „lining" 150 mm

Clamping facility model 564 V
The solid clamping beam along with adjusting stop and vacuum unit enables to remove workpieces from the customer's transport trolley and to fix them safely during machining. The manually displace¬able vacuum unit allows to receive workpieces that are to be machined on their tops.
