PURPOSE: A large optical lens grinding apparatus having a measurement tower is provided to precisely grind a work piece into a large optical lens by automatically controlling a turn table and a grinding tool based on measurement data. CONSTITUTION: A large optical lens grinding apparatus comprises a turn table(20), a tool transfer body, a tool transfer body rotating unit, a measurement tower(130), a CPU(Central Processing Unit), and a data input unit. The turn table, on which a work piece is fixed, is installed in a base frame(10). One end of the tool transfer body is coupled to a rotary shaft(14) of a first upper frame(11) while the other end is connected to a second upper frame, so that the tool transfer body is horizontally rotated around the rotary shaft. The tool transfer body rotating unit transfers the other end of the tool transfer body along a second upper frame and rotates the tool transfer body around the rotary shaft. The measurement tower comprises a measuring unit(131) which measures the ground state of the work piece. The CPU operates a turn table rotating unit(60), the tool transfer body rotating unit, and a tool transfer unit(90) based on input data. The data input unit inputs data about the operations of the turn table rotating unit, the tool transfer body rotating unit, and the tool transfer unit to the CPU.

PURPOSE: An active polishing tool is provided to reduce machining time and prevent uneven contact on a contact surface because a central shaft is allowed to rotate. CONSTITUTION: An active polishing tool(1) comprises a central shaft(10) which is moved to a machining position, a sliding member(20) which is moved up and down along the central shaft, a base plate(30) which is formed on an end of the central shaft, a polishing pad which is formed on the base plate, and a tension band(40) which connects the sliding member and the base plate and controls the surface shape of the base plate by interlocking with the up and down motion of the sliding member.
Abstract:
An apparatus for a high spatial resolution laser desorption ionization mass analysis is provided to easily using the sample without any particular processing progress by mass analyzing the sample being ionized in atmospheric pressure status. An apparatus for a high spatial resolution laser desorption ionization mass analysis includes a body(20), a reflecting unit(30), a sub mirror(40), a main mirror(50), and a capillary(60). The body is installed on the ion introducing unit of the mass spectrometer. The reflecting unit is installed on the inside or the front or the rear, and reflects the laser beam to the front. The sub mirror is installed in front of the reflecting unit, and diffuses the laser beam which is reflected by the reflecting unit to the body. The main mirror is on the front-end unit, and ionizes the sample by concentrating the laser beam which is diffused by the sub mirror, to the outside of the front. The capillary has an edge of one side which is separated from the concentrated focus of the laser beam by the main mirror to the rear side, and passes through the sub mirror, the main mirror and the reflecting unit, and the edge of the other side is installed to the mass spectrometer, and introduces the ion which is generated by concentrating the main mirror, to the mass spectrometer, and its inside is hollow.
