Kruesimatic G1

Compact, versatile, powerful & precise

General information

The timber processing center is suitable for all kind of applications such as timber framing, log homes, roof constructions, prefabricated elements and much more. Timbers can be cut with a minimal size of 1 inch by 2-3/8 inches and a maximum dimension of 7-1/2 inches by 12-1/2 inches. The machine is equipped with a NC-control system of the type PA 14XX. The control system consists of the operator console and the electronic cabinet. The electronic cabinet contains 24Volt DC input carts, relays output carts, analogue output carts for RPM settings and positioning carts for seven NC servo-axes.

1. Axis for timber transport (X-Axis).
2. Axis for aggregate frame vertical (Z-Axis).
3. Axis for aggregate frame horizontal (Y-Axis). Axes one to three can interpolate with each other.
4. Axis to rotate the circular saw (angle).
5. Axis to rotate the circular saw (bevel).
6. Axis to rotate the vertical milling aggregate.
7. Axis to rotate the horizontal five-spindle milling-unit.

Operator console of the Kruesimatic G1

The components that are installed in the electronic cabinet are seven AC servo-amplifiers, a frequency converter for the milling- and drilling aggregates, an electric clamp system, a 63 Amp. main switch, emergency stop circuit, motor overload breaker, contactors, relays, regulated current transformer 24 V DC, split transformer, etc. All cable connections to the machine are multi-prong connections.

The software to operate the machine contains all timber connections and joinery that can be processed with this machine. The programming of the software is an ongoing process to add more features and improvements. Updates are available periodically to upgrade the machine.

All processing data that is needed for a project can be designed in a CAD-CAM program such as Cadwork and converted into the machine language with a mouse click. Two newly developed tooth-belt caterpillar pears are used to feed and guide the timber in the X-Axis direction. They are driven simultaneously, using one servomotor with a no slick transmission, cardan shafts and gearwheel belts. With this method, it is possible to process timber precisely with length less than 19 inches up to unlimited length.

All milling-, cutting- and drilling aggregates are mounted to a frame-like cross-sledge (Aggregate frame). This aggregate frame is guided horizontally and vertically on hardened and smoothened bearings with high precision ball bearings and guide shafts. The aggregates are adjusted with servomotors that are driven by gearwheel belts and ball thread spindles. This guaranties a long live span and assures a precise positioning of all the aggregates.

The following tools are installed on the processing aggregates when fully equipped:

1. On top, one saw aggregate to be beveled and rotated with a 23.62 inch(600mm) diameter saw blade, powered with 7.5 KW.
2. In front, one drilling motor with two drilling spindles for horizontal drilling, powered with 1.8 KW.
3. In front, one slot-cutting aggregate powered with 1.8 KW.
4. At the bottom, one universal milling aggregate to cut notches, tenons and half laps. This aggregate can be rotated and is powered with 5.5 KW. The standard universal mill has a diameter of 10.63” (270mm) and a width of 2.76” (70mm). The end-mill diameter is 1-37/64” (40mm) and a dovetail mill can be installed as well.
5. At the back, a five-spindle milling aggregate, powered with 4 KW. Following tools can be installed:
   • One dovetail mill to cut dovetail-tenons and –mortises all the way around.
   • One 40mm end-mill to cut mortises, housings and others all the way around.
   • One 24mm end mill to cut smaller housings such as thread-notches in stringers.
   • One profile-mill or a drill bit for a variety of processing 's.
   • One 20mm end-mill for front drillings.
   • One pneumatic powered marking unit with a special gas-pressure ballpoint.

The great advantage of this processing center is that 12 different saw-, milling- and drilling tools plus a marking unit can be installed at the same time without changing tools. Seven of those tools can be rotated all the way around the Y-axis and the Z-Axis. Therefore, the machine is very flexible and has much more processing possibilities. Most of the timbers can be processed fully automated. In very rare occasions, the timber needs to be rotated manually and reprocessed in a different orientation.

The in-feed table is built to the right side of the machine and is about 26 feet (8m) long and 7 feet (2.1m) wide; it feeds the timber automatically to the machine. Timber up to 40 feet long can be processed without adding an extension table.

The output table is situated to the left of the machine. It is 26 feet (8m) long and equipped with an ejector bar and with six storage racks.

The machine needs to be sunk into a manhole to our specifications to get a machine table height of about 36”. The chips and off cuts will fall into this manhole. The waist material needs to be disposed from there. The manhole must be built so that it can be locked and accessed when the machine is turned off only.
