An apparatus including a controller, and at least two cutting head assemblies. The controller typically includes a computer processor, and a computer memory, having a computer program stored therein. The controller automatically controls the current load of a cutting motor of each of the at least two cutting head assemblies via current sensors, in response to monitoring real time current loads. The controller may also control feed mechanism speed. The feed mechanism may include a conveyor belt. The controller may also be programmed to control a position or height of each of the at least two cutting head assemblies with respect to the feed mechanism. The two or more cutting head assemblies may be attached to a frame, and the controller may control the movement of the frame perpendicular to the direction of movement of feeding mechanism. Cutting head pads may be monitored for wear and replaced if necessary.

An automated plant (10) for cutting and operating flat slabs made from ceramic or the like for typically but not exclusively manufacturing slabs intended for use as coating elements at both civil and industrial levels and for both indoor and outdoor environments, comprising a first macro-area (12) defining an area suitable for storing products consisting of semi-finished slabs or mother-slabs, a second macro-area (14) defining an area for storing auxiliary packing materials or consumable materials for operations or processes on said slabs, a third macro-area (16) defining a production area for processing, packaging, and packing daughter-slabs or sub-formats of slabs obtained from mother-slabs, a fourth macro-area (18) defining a finished product area or store for letting the products coming from the third macro-area (16) pass through/temporarily accumulate, said plant also comprising automatic handling means for slaving and handling materials and semi-finished and finished products between said macro-areas and internally thereto, and a central control unit for programming, managing, and controlling the operation of said macro-areas and the interaction therebetween.

A guide device comprising a hollow body configured to receive a drill bit, the hollow body having a first end; a second end; and a continuous section intermediate the first end and the second end; an opening extending from the first end through the continuous section to the second end; and at least one aperture located on the hollow body intermediate the first and second end of the hollow body.

Disclosed is a machine for forming saw cuts into sidewalk concrete slabs, the machine comprising a frame, rubber tracks attached to the underside of the frame to self-propel the machine in a travel direction along a sidewalk during use, and a cutting assembly mounted to the frame. The cutting assembly comprises a saw for forming saw cuts, a linear actuator for moving the saw at a depth into the sidewalk, and a screw drive motor to move the saw to form the saw cut in a direction perpendicular to the travel direction. While road repair machinery has the luxury of more space, machines for sidewalks are smaller and tighter. The machine in accordance with the teachings of this invention uses a newly designed cutting assembly to keep the size of the machine useable for sawcuts in sidewalks.

A method for operating a machine tool that includes an electric motor for driving a drilling tool and an open- and closed-loop controller for open- and closed loop control of the motor power. The method includes: operating the machine tool in a tapping mode at a first rotational speed value, where the first rotational speed value is lower than a predetermined idling speed value of the electric motor; detecting a predetermined first threshold value for the motor current; reducing the motor current to a predetermined second threshold value when the first threshold value is exceeded; operating the machine tool at a second rotational speed value, where the second rotational speed value is lower than the first rotational speed value; operating the electric motor at a predetermined motor current value; and operating the controller for closed loop control of the motor power via the motor current with an oscillating action.

A device system, including a remote control (13) having a device housing (31) and a first radio unit (38), a tool device with a second radio unit and a radio link which connects the first radio unit (38) of the remote control (13) to the second radio unit of the tool device. The first radio unit is (38) is arranged on a front side (57) of the device housing (31), wherein the front side (57) is lying opposite a rear side (56) of the device housing (31) facing the operator in a working position of the remote control (13).

A mosaic tile design and manufacturing system is comprised of a mosaic design application, a network server and a tile cutting apparatus. A mosaic artist can use the mosaic design application to specify the placement, color and shapes of a plurality of mosaic tile comprising a mosaic design. The tile shapes can be a combination of standard and non-standard shapes, and the design tool can generate instructions that can be applied by the server to the tile cutting apparatus to control the cutting apparatus to make custom tile cuts that result in a tile with a non-standard shape.

A processing system includes a processing apparatus having functional units including a holding unit that holds a workpiece by a holding surface, a processing unit that processes the workpiece held by the holding unit, and a feed unit that moves the holding unit and the processing unit relatively. The processing system further includes a detecting unit that is provided for part or all of the functional units and detects any of vibration, current, voltage, load, speed, torque, pressure, temperature, flow rate, change in a taken image, and the thickness of the workpiece, and a data accumulating unit that accumulates information included in a signal output from the detecting unit as data.

A milling machine for milling a surface of a roadway includes a frame and a milling assembly having a cutter drum that is mounted for rotation with respect to the frame. The cutter drum has a drive shaft on which a sheave is mounted. A primary drum drive assembly is adapted to rotate the cutter drum with respect to the frame. The primary drum drive assembly includes a drive belt that cooperates with the sheave on the drive shaft for the cutter drum to rotate the cutter drum. A belt lift assembly may be operated to selectively disengage the drive belt from the sheave of the drive shaft for the cutter drum.

A method for the unique allocation of a first system component (14) of a device system (10), designed as a remote control, to a second and third system component (13, 12) of the device system (10), wherein the remote control (14) can be connected to the second system component (13) via a wireless and cableless communication link (35) or via a first cable or plug connection (36).
