Integrated machining device for grinding and polishing diamond and method thereof

A machining method using an integrated device for grinding and polishing a diamond, wherein:

• the integrated device for grinding and polishing the diamond, comprises:
• a base device, and
• a grinding and polishing device, wherein:
• the base device comprises a sliding base configured to feed along a lateral direction and a base configured to be rotatably connected to the sliding base around a vertical direction,
• the base comprises a fixture configured to clamp the diamond,
• the grinding and polishing device comprises a shaft disposed along the vertical direction,
• an inner grinding wheel and an outer polishing wheel are respectively sleeved on the shaft,
• 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 vertical direction is configured to be adjusted,
• the diamond on the fixture is ground and polished by rotations of the inner grinding wheel and the outer polishing wheel, feeding of the sliding base, and a rotation of the base,
• the fixture comprises a body, two sliding blocks, and two adjusting screws,
• a top wall of the body comprises a base wall and a protruding platform protruding from the base wall,
• the protruding platform comprises two positioning walls facing the base wall and vertically disposed,
• the base wall of the body is recessed to define two sliding grooves leading to a side wall of the body,
• the two sliding grooves are respectively disposed along the two positioning walls,
• tops of the two sliding blocks horizontally protrude to define two protruding portions,
• the two sliding blocks are respectively slidably connected to the two sliding grooves,
• the two protruding portions are disposed on the base wall,
• the two protruding portions form two locking walls,
• the two locking walls of the two sliding blocks and the two positioning walls respectively face each other,
• the two adjusting screws are respectively connected to the two sliding blocks and the body to adjust the two sliding blocks to slide along the two sliding grooves by the two adjusting screws, and
• the diamond that is stuck to the base wall is clamped by the two locking walls and the two positioning walls, and
• the machining method comprises:
• sticking the diamond to the fixture with adhesives,
• assembling the fixture to the base,
• adjusting the upper and lower position relationship of the inner grinding wheel to enable a bottom surface of the inner grinding wheel to be lower than a bottom surface of the outer polishing wheel,
• rotating the inner grinding wheel, rotating the base, and feeding the sliding base to grind the diamond,
• adjusting the upper and lower position relationship of the inner grinding wheel to enable the bottom surface of the inner grinding wheel to be higher than the bottom surface of the outer polishing wheel, and
• rotating the outer polishing wheel, rotating the base, and feeding the sliding base to polish the diamond.
