Combined contour milling and circular sawing machine

The hiring concerns a contour milling and circular sawing machine for sawing and milling any contours on grave monuments, which can also be used as a circular saw for certain work is to be used.

It is known that so far in the stone industry the production of the contours of grave monuments by hand by means Hand grinder and prior flogging is carried out.

This innovation was created in order to introduce rationalization here as well. “Besides, it is with the same machine possible to saw straight and curved folds or other sawing work with a saw blade arranged behind the pre-cutting tool to execute with.

Milling the fillets at the ends of the workpieces, which For milling upwards using a template, not possible due to the missing component for lifting the milling cutter and its quill is, is to be achieved by a further innovation described in the technical course. Through photocells it will be on a white Background black drawn contour scanned and by appropriate commands for horizontal and vertical feed controlled the tool. That the stencil wheel is still on the stencil while this is photoelectric Control takes place, does not affect the accuracy of the control process.

A coordinate control switch built into the control panel and pendulum control box allows the tool to be controlled for the rounding also by hand.

Another innovation in the above machine is the driven one Stencil wheel by a rotating field magnet with a downstream Reduction gear represents «, this means that an additional feed force can be applied via the template wheel, which in turn creates the possibility of making relatively steep turns.

The speed of the screen wheel adjusts itself automatically to the Curve shape while the horizontal support feed is constant via the threaded spindle.

With a turntable attached to the narrow front sides Consoles, an efficient setting up and setting down of the workpieces is achieved. While one side is in the milling process is located, on the other hand, the benching can be done respectively. The turntable can also be used to make angular cuts on its upper side with the saw blade will.

A bridge 2 is arranged vertically adjustable on vertically arranged stands 1. The support 5 is moved back and forth on this via a G-threading spindle 5 and the feed unit 4. A quill 6, which is raised and lowered by the template wheel 7, sits vertically displaceably within the support 5. A template 8 is placed on the bridge 2 in accordance with the contour to be milled. The template wheel 7 is driven via a rotating field magnet 9 and a downstream reduction gear 10.

The electric motor 11 takes the cylindrical milling cutter on the front 12 and the saw blade 13 on the back.

On both sides of the turntable upper part 14, on the narrow end faces, consoles 15 for receiving the workpieces 16 are provided appropriate.

Clamping devices 17 hold the workpieces 16 firmly. the The turntable is also placed on the rails 20 transversely to the preseeding and sawing direction by the rollers 19 built into the lower part 18 movably arranged.

By a built-in in the control panel 24 and in the pendulum control box 25 coordinate control switch 26, the Commands for the feed units for horizontal adjustment and vertical adjustment 23 can be controlled by hand.

The next to the template 8 attached, drawn distorted contour of the rounded arch 21 is divided by two or four Photo cells 22 are scanned and the commands on the feed units for horizontal adjustment 4 and vertical adjustment 23 transferred.
