The application relates to a quartz lower DOME product processing jig which comprises three graphite jigs, the lower part of the side of each graphite jig is formed with a spherical surface groove, the middle part is formed with an arc surface groove, and the top part is formed with a flange groove; the arc surface groove is connected with the spherical surface groove; the spherical surface grooves of the three graphite jigs enclose a ball head space for accommodating a ball head; the arc surface grooves of the three graphite jigs enclose a pipe body space for accommodating a pipe body; and the flange grooves of the three graphite jigs enclose a flange space for accommodating a flange; the ball head space, the pipe body space and the flange space are coaxially distributed. The processing jig provided by the application encloses the coaxially distributed ball head space, the pipe body space and the flange space by the three graphite jigs, is used for sequentially attaching the ball head, the pipe body and the flange, and can jointly guarantee the coaxiality of the flange, the pipe body and the ball head and the runout of the ball head; meanwhile, the three graphite jigs are designed by using the self-centering principle of three-jaw chucks, and do not need to fix and adjust parts for many times.

The application discloses a large-chord-width long-cantilever fan blade tip high-precision processing method, which comprises the following steps: firstly, using a three-coordinate to measure the size of a first-stage fan rotor and a second-stage fan rotor, including an axial length, a blade tip diameter and a blade tip angle; then, sequentially assembling the second-stage fan rotor and the first-stage fan rotor to a process shaft provided with a supporting plate and fastening through bolt connection; then, installing the process shaft provided with the second-stage fan rotor and the first-stage fan rotor to a chuck of a grinding machine; setting blade tip processing basic parameters of the first-stage fan rotor and the second-stage fan rotor and blade tip processing parameters of the first-stage fan rotor and the second-stage fan rotor; and finally, starting to grind the blade tip. The application controls the grinding quality from aspects of process control, grinding scheme and processing parameters during grinding, solves the problems of unqualified diameter, run-out and roughness in traditional blade tip processing and vibration and knife biting during processing, has high processing efficiency and meets the processing quality requirement.
