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 transportation carrier is provided for automated lens manufacturing in a lens manufacturing facility, including: at least one block piece or one block piece receiving section; and an electronic paper display configured to display at least an up-to-date status information of the manufacturing process of the optical elements carried by the transportation carrier that is intelligible for a human operator without use of a reading device, the electronic paper display including a wireless communication module and a memory configured to exchange and to memorize job information and to process information for lenses to be manufactured, in which the electronic paper display is further configured to function as a passive RFID tag with the wireless communication module.

A machine tool includes a bed including a bottom surface and legs arranged at three positions of the bottom surface. The bed includes two oblique sides arranged such that the bottom surface has a triangular shape. The machine tool also includes a first support surface arranged on the bed and extending along a substantially horizontal first axis, a work table supported by the first support surface so as to move along the first axis, a second support surface arranged on the bed and extending along a substantially horizontal second axis, which is perpendicular to the first axis, and a machining unit supported by the second support surface so as to move along the second axis. The second support surface is located higher than the first support surface.

A polishing apparatus includes a polishing device, a polishing fixing device, and a controller. The polishing fixing device includes a rotating mechanism, a sensor, a movement compensation assembly, a first moving assembly and a second moving assembly. The sensor in the polishing fixing device senses pressure applied to the workpiece during polishing, the movement compensation assembly can drive the rotating mechanism to move in compensation, so as to keep the polishing pressure within a certain range for uniformity in polishing, improving the polishing quality and production efficiency of the workpiece.

A polishing system includes a platen having a top surface to support an annular polishing pad, a carrier head to hold a substrate in contact with the annular polishing pad, a support structure extending above the platen and to which one or more polishing system components are secured, and a support post. The platen is rotatable about an axis of rotation that passes through approximately a center of the platen. The first support post has an upper end coupled to and supporting the support structure and a lower portion that is supported on the platen or that extends through an aperture in the platen.
