The present invention provides an improved online burr removing device for a wheel. When the device is used, equal rotating speeds of the inner brush and the outer brush can be realized by using one driving motor, thereby avoiding the problem that the linear speed is low in the center but high at the outer edge when an integrated brush rotates at the same angle; meanwhile, the device has the characteristics of high automation degree, advanced process, simple structure and high safety and stability.

An eyeglass lens processing apparatus for processing a periphery of an eyeglass lens includes: a lens chuck shaft configured to chuck the eyeglass lens; a shaft angle changing portion configured to change a shaft angle of the lens chuck shaft; a first processing tool unit including at least one spindle at which a first processing tool is provided; a second processing tool unit that is disposed to oppose the first processing tool unit and that includes at least one spindle at which a second processing tool is provided; and a controller configured to change one of the first and second processing tool unit to be used for processing the eyeglass lens to the other of the first and second processing tool by controlling driving of the shaft angle changing portion to change the shaft angle of the lens chuck shaft.

A device for fine processing of optically effective surfaces on workpieces has a workpiece spindle which protrudes into a working space and by which a workpiece to be polished can be rotationally driven about a workpiece axis of rotation. Two tool spindles are associated with the workpiece spindle and protrude into the working space oppositely to the workpiece spindle. On each tool spindle, a polishing tool can be rotationally driven about a tool axis of rotation and is retained so that the polishing tool can be axially advanced along the tool axis of rotation. Furthermore, the tool spindles can be moved together in relation to the workpiece spindle along a linear axis extending substantially perpendicularly to the workpiece axis of rotation and can be pivoted about different pivoting adjustment axes, which extend substantially perpendicularly to the workpiece axis of rotation and substantially perpendicularly to the linear axis.

A high efficiency grinding machine for grinding the pin on a crankshaft has a machining space with a grinding wheel mounted on the lower end of an arm to form a pendulum assembly. A headstock supports the crankshaft in the machining space. A pivot drive rocks the pendulum assembly back and forth equal distances about the equilibrium position causing the grinding wheel to follow the non-circular path of a pin as the crankshaft as it is rotated about its elongated axis.

A CMP apparatus includes a polishing unit 3, a cleaning unit 4, a load/unload unit 2, a transfer unit, and a control section 5 configured to control transfer of a substrate in the transfer unit. When the polishing unit includes a plurality of polishing sections, or the cleaning unit includes a plurality of cleaning sections, the control section 5 can set a test mode that operates the polishing section or the cleaning section for a test to some of the plurality of polishing sections, or some of the plurality of cleaning sections, causes a substrate to be transferred to the polishing section or the cleaning section to which the test mode is not set, and causes a test substrate different from the substrate to be transferred to the polishing section or the cleaning section to which the test mode is set.

The invention describes an apparatus (1) for a cutting edge preparation of cutting tools (5), in particular of drills or milling tools or similar tools (5), in particular of hard-metal cutting tools, wherein during a relative movement the cutting tool (5) interacts in a machining fashion with a flexibly-bonded grinding body (2) that is provided with abrasive particles, the particles of the grinding body (2) influencing the edge geometry of the cutting tool (5),

wherein the grinding body (2) is adapted with its dimensions substantially to the dimensions of the respective cutting tool (5) that is to be prepared and is accommodated in an exchangeable holder (4) which is arranged in a region of a processing device, in particular of a tool grinding machine, and is held such that it is machinable by the cutting tool (5) for the cutting edge preparation. Furthermore, a corresponding method and a corresponding grinding body (2) are given.

In a machine and in a method for processing lateral edges of glass plates, plates of stone material, and plates of synthetic material, there is a group of gripping members of the plate configured to hold a plate in a horizontal position. The plate is caused to advance in a conveying longitudinal direction, in such a way as to bring a lateral edge of the plate to engage in succession an aligned series of grinding tools forming part of a stationary machining unit. In one example, the group of gripping members of the plate is rotatably carried around a vertical axis by a carriage, which is movable in the conveying longitudinal direction and in a transverse direction orthogonal to the longitudinal direction. The gripping members are carried by the carriage in such a way as to be adjustable in position, by means of electronically-controlled actuator devices, with respect to the carriage and relative to each other.

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.

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 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.
