A grinding apparatus for grinding a floor, the apparatus comprising a body having a travelling mechanism which enables the body to travel across a floor while the apparatus is grinding; a first grinding head incorporating at least one grinding tool and having an operable configuration in which the first grinding head is able to grind a first floor portion; and a second grinding head incorporating at least one grinding tool and having an operable configuration in which the second grinding head is able to grind a second floor portion; wherein the first and second grinding heads are mountable to the body whereby their positions relative to the body are able to be varied.

A grinding machine for machining workpieces includes a workpiece headstock and two grinding headstocks. A first grinding headstock has two grinding spindles each with one grinding wheel for grinding first and second planar and non-planar external surfaces. A second grinding headstock has a grinding spindle having a grinding wheel for grinding a central bore in the workpiece, and a clamping device to clamp the workpiece. First, the bore and the first planar and any non-planar external surface are ground on one side of the workpiece. Then, the workpiece is clamped in the bore. The second planar external surface can then be ground in the same grinding machine with one of the grinding wheels of the first headstock. The clamping device attached to the second grinding headstock is such that the central axis of the clamping device is exactly aligned with the central axis of the workpiece headstock.

The invention relates to an apparatus for honing a bore in a workpiece, having an apparatus base, having a turntable arranged on the apparatus base, with a plurality of workpiece receptacles, having at least one loading station for loading and unloading from the workpiece receptacles, having at least one honing station with a horizontal honing unit and with a displacement device for displacing the horizontal honing unit relative to the turntable, and having at least one tool magazine for receiving a plurality of honing spindles.

A sanding machine, in particular for processing wood surfaces, includes a support and transport plane for the forwarding of the workpieces to be processed; and a belt sanding unit with a transverse abrasive belt inside which a pressure pad is arranged obliquely. The pressure pad is divided into a plurality of pressure elements which can be actuated individually and are controlled by respective sensors that constitute a control beam, Methods are described for compensating the different distances between sensor and respective pressure elements that avoid adaptations of the position of the workpiece to be processed, in particular if the machine contains further non inclined processing units. The sanding machine is particularly suitable even for the processing of large workpieces.

A system for robotic paint repair that can include a consumable abrasive product configured to abrade a substrate, a tool configured to drive the consumable abrasive product to abrade, a backup pad configured to couple with the consumable abrasive product, a robotic device configured to manipulate the tool, a pressure regulating apparatus mountable to the robotic device and configured to apply a desired pressure to the consumable abrasive product, a sensor configured to measure at least one of a rotational velocity of the backup pad or a debris pattern from the substrate that results from abrading, and a pressure controller configured to control the pressure regulating apparatus to apply the desired pressure based upon the at least one of the measured rotational velocity of the backup pad or the measured debris pattern.

A rock sanding device includes a base, a bottom sanding plate, an adjustable connecting rod, an elastic loader, a connector, a side sanding brush, a top sanding plate, an inner rod, a prong and a drill rod. The top of the drill rod is fixedly connected with the rotating shaft of the external water drilling rig and the external water drilling rig has a water inlet joint to introduce water into the drill rod. The inner rod and drill rod are connected and fixed coaxially, and the bottom of the drill rod is symmetrically welded with four prongs. The rock specimen is placed in the center of the side sanding brush. The top sanding plate and the bottom sanding plate are provided in the top side and bottom side of the rock specimen, respectively.

The feeding unit includes a base plate, and a cross member. The base plate receives the gemstones, affixed to the gemstone holders. The cross member is an automated moving member, configured such that a home position of the cross member coincides with a pre-defined point on the base plate. Accordingly, the gemstone, along with its gemstone holder, when received at the base plate is picked up by the cross member, specifically, by the first gripping member and the second gripping member, by a detachable contact established between the gemstone holder and the cross member, such that the cross member transfers the gemstone holder positioned on the base plate to a pre-defined position on the feeding unit.

An apparatus includes a frame, a separating plate connected to the frame, a sensor aimed at the separating plate, and a support surface connected to the frame. The separating plate and the support surface are coupled with the frame so as to allow for a relative movement between the separating plate and the support surface in a first direction. The separating plate and the support surface are arranged such that when a grinding disc rests against the support surface and when the separating plate and the grinding disc move towards each other, at least one first edge of the separating plate is pushed over grinding disc. The sensor is arranged such that when the separating plate is pushed over the grinding disc, the grinding disc is between the sensor and the separating plate.
