Northwood FabCenter FC 138SW
www.northwoodmachine.com

The Northwood FabCenter FC138SW was designed to do the work for a bridge saw and edging machine, while also having the ability to shape bump-outs and special shapes as easily as a straight edge. It can also process complex edges as simple as a flat edge.

The FabCenter, built on the SW 138 Stone Router platform, is Northwood’s latest innovation, and it was designed to provide an affordable, yet high-tech solution for smaller shops that process as little as four or five slabs per day.

The overall concept was to allow small shops to join the “digital revolution” and build a kitchen using one machine from start to finish. This technology revolution starts with Northwood custom software, StoneVision. The digital template is imported into StoneVision, allowing for 100% digital operation with no need for mylar templating. When coupled with Slabsmith software, users can digitally lay out and grain-match each slab without leaving the office. Born from technology and lessons learned with the introduction of Northwood’s SawJetTM, the StoneVision software automatically tool-paths the parts to be cut. The cutting process begins with the slab saw, powered by a Fanuc-drive, extreme-duty spindle. All straight edges are cut with the slab saw, and all radius cuts are done with the with the finger bit, providing a complete cutting process. Pods are then placed on the table with the help of the unit’s laser pod and part placement system. Edges are processed and polished in one setup with the proven EDS (Extreme Duty Spindle).

Marmo Machinery USA CTEC 3A

Park Industries Titan Digit-AllTM SlabCenter
www.parkindustries.com

Park Industries has introduced the new Titan Digit-AllTM SlabCenter, an all-in-one CNC stone fabrication machine for countertop production. The Titan Digit-All allows fabricators to dimension, shape and edge-finish full slabs using just one machine, on one table, with one operator. The machine saves time and labor by eliminating material handling steps on separate machines, the company reports, as there is no need to lift material from one set-up to another.

The Digit-All’s footprint also conserves shop space when compared to dual zone or shuttle table CNC systems, according to Park. With just a few simple steps, fabricators can completely fabricate an entire slab at one station with finger-push part positioning.

The Titan was designed to be fast and easy, as operators can call up programs using a point-and-click method with a bar code reader. An overhead laser projects where the vacuum pods should be placed on the table, with precise accuracy. After the pod placement, the operator starts the sawing cycle. An independently controlled CNC saw dimensions natural stone or quartz material slabs with extraordinary accuracy. After the parts have all been separated on the slab, the edge-finishing program is called up by bar code, and the parts are floated into position by reverse vacuum airflow. One operator can effortlessly guide the common-line cut separated parts to their edge-finishing location using the guidance from the overhead laser. There is no need for a second worktable or a material handling system. The parts are then ready for shaping and edge polishing.

For smaller shops, this concept allows fabricators to produce kitchens with just one machine. For medium to larger shops, the Titan Digit-All CNC SlabCenter gives fabricators the flexibility to route their job flow processes based upon their production schedule. The machine also provides the peace-of-mind to schedule machine maintenance on other machines without impacting a production schedule.

Park Industries Titan 1016
www.parkindustries.com

The integrated base architecture and massive step-up aluminum worktable of the Titan 1016 offers easier table access for maximum part placement in one set-up. The 96- x 192-inch worktable allows for multiple parts to be set up so operators can process many parts (even an entire kitchen) with unattended cycle time.

Users can quickly convert templates into accurate machine code with point-and-click simplicity directly at the machine, due to an on-board laser digitizing system. Alternatively, users can convert and program from the standard electronic DXF files at the control unit with the TouchStone programming system.

The machine can cut at a rate of 2,360 inches per minute, or more, with the 24-horsepower, variable-speed spindle drive system that runs up to 10,000 rpm. An optional 3-horsepower saw blade drive with its own precision slide system is available for complete, programmable 360-degree continuous rotation.

The automatic tool changer was designed to get to the right tool position quickly, and it also washes the tool holders between every change for less wear, less operator intervention and a better grip. There’s also a smart sensor that prevents putting a tool back into a full pocket, and a laser tool management system measures and accommodates for tool wear, prolonging the life of your tools and saving operator set-up time.

The Titan’s HyperdriveTM precision-ground, helical rack-and-pinion drive maximizes tool life and improves cut quality (accurate to .0004 inches in 13 feet of travel). The fast acceleration and deceleration makes for quick tool changes. Plus, the smooth, quiet operation and easy maintenance makes the Titan easier on the operator.

www.marmousa.com

Also for edging, Marmo Machinery USA offers the Maxi-BL, featuring a user-friendly operating system that ensures a high rate of production at a low cost per lineal foot, the company reports. The Maxi-BL can shape and polish marble, granite and ceramics with a bullnose, straight and inclined profile and with a thickness of up to 80 mm.

This machine has a carriage that is driven by a system of levers and rods, on which are mounted six shaping/polishing units driven by hydraulic motors. The shaping of the bullnose edges does not require shaped wheels because it is carried out with a common diamond flat wheel. The continuous movement of the abrasive on the shaped edge during polishing allows excellent finishes to be achieved. The carriage can be locked into any position to make inclined edges.

The rotation of the carriage is accomplished by means of levers and rods driven by an innovative and unique system that employs highly resistant cog belts and a single gear motor. The belt’s sliding surface is plated with anti-wear stainless steel.

All versions feature a self-diagnostic computerized control system. The control and positioning of all moving parts are performed completely automatically by the computerized system. The MAXI-BL is monolithic in shape, sandblasted, painted and oven dried.

Marmo Meccanica LCH-2L
www.marmomeccanica.com

The LCH-2L from Marmo Meccanica can work as a common polisher for flat edges on slabs ranging from 1 to 6 cm thick, and it can also realize a V-shaped mill at 90 degrees on slabs up to 2 cm thick in engineered stone or other materials, with a maximum depth of 13.5 cm.

The first step is polishing and edge chamfering plus the V-shape milling at 90 degrees with two mandrels that are adjustable in height and depth - one at the entrance and the other at the exit. These bear two V-shaped diamond wheels, the first one has a rough grain for the pre-cut, and the second one has a fine grain for refining the first cut.

For the second step, outside the machine, the two portions of slab can be glued along the inclined sides of the 45-degree milling. Meanwhile, for the third step, the L-shaped piece can be refined and chamfered by the same machine along the external gluing line, laying the larger portion on the conveyor belt and vertically inserting the smaller portion between the rubber rollers and the abrasives. This way, the lower chamfer can refine the edge.

In the standard version, this edge polisher can be equipped with one incoming calibrating/drip-cut unit, one outgoing shaping/drip-cut unit or both.

Pedrini Galaxy B220
www.pedrini.it

The Pedrini Galaxy B220 automatic slab polishing machine for marble or granite has been reinforced with exclusive technology that achieves a high production speed with reduced costs for consumables and maintenance. Such results stem from its capacity to process slabs up to 2200 mm wide with a beam speed up to 60 meters per minute. The PC-controlled touch-screen color monitor and “Field Bus” data transmission system are in place to make the machine easy to use and reliable in performance.

The transversal movement of the beam is driven by an extensively tested “gearless” transmission that works into protected dry housings inside the bridges. This moves the beam smoothly and maintenance free, and it does not harm the mobile beam with additional weight.

The polishing heads are operated by Pedrini’s patented direct-drive rotor spindles that work without transmission belts. The rotor spindles are further equipped with an easy-to-use individual device for precise centering to the processing plane that provides the best operating conditions for the abrasives - with minimal tool consumption and high processing quality. The machine’s automation is managed through soft logic on the Windows NT operational system.

Through a simple interface, the operator controls and programs all functions, including minimal lift of the heads upon outlet of the slabs and quick head lowers as slabs enter the line - all while keeping the working pressure unchanged.

Pedrini Resinline
www.pedrini.it

Resinline is the range of plants manufactured by Pedrini for the resin treatment of marble and granite. This process improves a material’s mechanical and aesthetic features and allows a company to commercialize dull and inhomogeneous ones that are not otherwise useable in their natural condition. Resinline plants are customized to perform various production speeds, ranging from six to 60 cycles per hour. The structure of the trays provides them optimum positioning, which is particularly needed when crossing seams are present on transported elements. Vertical movements are performed through lifts that move at high speed along four columns. Loading and unloading operations are performed manually or through automatic suction robots. PC-controlled tables allow the slabs to be turned over for application of a reinforcement net when required as well as for book-matching and block reconstruction. All ovens (driers) are equipped with a pipe system that distributes the air on stones upper and lower surfaces, which allows for uniform treatment with maximum energy savings. A manual pump with robotic controls provides for the resin application.

Plants for processing particularly brittle stones are equipped with a station for application of the reinforcement netting, and with a vacuum chamber where depression allows the air bubbles to quickly exit the material, thus improving resin penetration.
