Described is an apparatus for robot-aided grinding, comprising the following: a manipulator, a linear actuator, and a grinding machine which includes a rotating grinding tool and is connected to the manipulator via the linear actuator. The apparatus further comprises a protective cover that partially surrounds the rotating grinding tool, the rotating grinding tool protruding from the protective cover at least on a first side. An adjusting mechanism is provided which connects the protective cover to the grinding machine and is designed to adjust the position of the protective cover in relation to the grinding machine.

A radius adjustment apparatus includes a yoke assembly having a yoke body defining a threaded inner channel and a threaded yoke adjuster rod situated in the inner channel, the threads meshing together such that the yoke body is moved forwardly or rearwardly upon rotation of the adjuster rod. The adjuster rod is actuated by an attached adjuster knob. The yoke includes a pair of yoke arms each having a proximal end coupled to the yoke body and a distal end coupled to opposed ends of a bearing arm, the bearing arm extending between the distal ends. The bearing arm may be flexed or arched about a midpoint attachment fastener. A carriage, which may be coupled to a traditional grinding machine, is slidably coupled to the bearing rail for manual movement therealong. Slidable movement along the flexed or arched bearing rail causes a workpiece to receive a spherical or circular grind.

A pneumatic device includes a casing unit defining a first chamber, a receiving space and a front space; a cylinder movably received in the receiving space, defining a second chamber and a releasing room, and having an air passage unit and an annular groove; and a hollow piston rod in sliding engagement with the cylinder, and having an inlet channel, a communicating room and an air hole unit. The cylinder and the piston rod are movable to change between a pneumatic state, where the air hole unit is communicated with the inlet channel, the annular groove, the communicating room and the second chamber, and an air discharging state, where the air passage unit is communicated with the second chamber, the receiving space and the releasing room.

A glass-ceramic article includes at least one substrate, such as a plate, made of glass-ceramic, the substrate having a face including a microtexturing such that the arithmetic mean surface roughness Ra, measured according to standard ISO 4287, is between 0.14 and 0.40 μm, and the total roughness, Rt, measured according to standard ISO 4287, is between 1.15 and 5.00 μm.

A system for polishing a surface of a component includes a motorized apparatus including a body, a drive system coupled to the body, and an arm including a proximal end coupled to the body and a distal end opposite the proximal end. The motorized apparatus further includes a tool coupled to the distal end of the arm. The tool is configured to polish the surface of the component. The motorized apparatus also includes an actuator coupled to the arm. The system also includes a controller configured to position the tool relative to the component by positioning at least one of the body and the arm relative to the component to reach the target area on the component while maintaining a distance between the tool and the body that is less than a threshold distance. The threshold distance is less than a full reach of the arm and is determined to prevent vibrations of the tool and the arm from exceeding a predefined level.

A method for producing a roll grinder with two running rollers, a handle body arranged between the running rollers and can be rotated relative thereto, and at least one grinding or polishing surface. The method includes steps of: producing the handle body; measuring the handle body in order to determine the actual dimensions of the handle body; providing at least two differently dimensioned types of spacer elements, by means of each of which a different distance can be set between one of the running rollers and the handle body in the installed state of the roll grinder compared to at least one other type; selecting one of the types of spacer elements provided depending on the measured dimension of the handle body; and connecting the handle body to the running rollers to form the roll grinder while using at least one spacer element of the type selected.

An integrated device for grinding and polishing a diamond and a method thereof are provided. The integrated device for grinding and polishing the diamond comprises a base device and a grinding and polishing device, the base device comprises a base configured rotate around a Z-axis, the base comprises a fixture configured to clamp the diamond, the grinding and polishing device comprises a shaft disposed along the Z-axis, the outer polishing wheel surrounds the inner grinding wheel, the shaft drives the inner grinding wheel and the outer polishing wheel to rotate together, an upper and lower position relationship between the inner grinding wheel and the outer polishing wheel along the Z-axis is configured to be adjusted, and the diamond on the fixture is ground and polished by rotations of the inner grinding wheel and the outer polishing wheel, feeding, and a rotation of the base.

A grinding machine includes a machine bed on which a workpiece spindle with a workpiece holder and a tool spindle with a tool holder are arranged. A workpiece held in the workpiece spindle, relative to a tool held in the tool holder, is displaceable along an X-axis running in a first direction parallel to the surface of the machine bed, is displaceable along a Y-axis, running in a second direction parallel to the surface of the machine bed, is displaceable along a Z-axis running perpendicular to the surface of the machine bed, is rotatable about an A-axis running parallel to the surface of the machine bed, and is rotatable about a C-axis running perpendicular to the surface of the machine bed. The tool spindle is completely kinematically separated from the workpiece spindle. Movements along the X-axis, about the A-axis and about the C-axis being carried out by the workpiece spindle.

The present disclosure includes one or more resilient members for use in an apparatus used to form lapping plates. The resilient members can permit processing members such as charging elements and shaving blades to conform to irregularities in surface topography of lapping plate platens.
