Grinding mount holder assembly, apparatus and method for manufacturing a sample

A grinding mount holder assembly comprising:

• a mount including an end wall adapted to fixedly receive one of front and rear surfaces of a sample, and having a side wall enclosing a side surface of the sample, the mount adapted to mount the sample so that the other of the front and rear surfaces of the sample is exposed;
• a holder including a vertical wall defining an open space in which the mount is inserted at an end portion of the holder;
• and
• a base including a vertical wall defining a space in which the holder is rotatably installed, and further including a pressing member for pushing out the mount inserted in the open space of the holder.

A sample manufacturing apparatus comprising:

• a main body having a plurality of rotational disks;
• an arm installed on the main body to be capable of moving leftward and rightward;
• and
• a grinding mount holder assembly installed on the arm to be capable of moving frontward and rearward, the grinding mount holder assembly capable of mounting a sample so that one of a front and rear surface of the sample is ground by the rotational disks, and further capable of reversing the front and rear surfaces of the sample so that the other one of the front and rear surface of the sample is ground by the rotational disks.

A method for manufacturing a sample, comprising:

• placing the sample in a mount that is inserted in a holder so that a front surface of the sample faces a lapping disk;
• pushing the mount by a pressing member so that the sample is contacting the lapping disk pressing member;
• grinding the front surface of the sample by rotating the lapping disk;
• mirror-polishing the front surface of the sample;
• rotating the holder including the mount by 180° after the pressing member is retracted;
• disposing the sample so that a rear surface of the sample faces the lapping disk;
• pushing the 180°-rotated mount by the pressing member so that the sample is contacting the lapping disk;
• and
• grinding the rear surface of the sample by rotating the lapping disk.

A method for manufacturing a sample using a grinding mount holder comprising a mount in which the sample is fitted so that a front surface of the sample is exposed, a holder in which the mount is inserted, a base to which the holder is rotatably coupled, and a pressing member provided on the base to press down the mount inserted in the holder, the method comprising:

• grinding the front surface of the sample;
• mirror-polishing the front surface of the sample;
• rotating the mount in the holder;
• and;
• grinding a rear surface of the sample without replacing the mount.

A grinding mount holder assembly for positioning a sample, the assembly comprising:

• a base configured to position the sample over a plurality of grinding wheels;
• a sample holder pivotally connected along an axis to the base;
• and
• a pressing member disposed in the base adapted to press a side of the sample against one of the plurality of grinding wheels.
