The present invention relates to a tool magazine of a machine tool, such as a column moving type machining center, wherein when a tool is replaced by a tool replacing part and a tool replacing part transfer part, a tool accommodated in a clamping part of a tool magazine unit is introduced or extracted from a direction perpendicular to the axis of the tool, and a flange part of the tool is directly clamped by a holding part of a replacing arm, thereby replacing the tool with the tool replacing part and the tool replacing part transfer part. In the medium-sized or large-sized machine tool having a long length in the width direction, the tool changing time can be shortened, the productivity can be improved, and the stability and reliability can be improved by minimizing collision or mechanical interference, wherein the tool magazine unit is provided on a saddle, a tool changing part is movably provided on the saddle, and the tool changing part is provided on the saddle. The tool changing and transferring part transfers the tool changing part independently from the stand column.

The invention relates to a PC spherical surface processing machine for ceramic ferrule, the main point of which is that the workpiece is loaded and unloaded in the air pipe through compressed air after being automatically sorted by a vibrating hopper and a discrimination system; after the grinding of the workpiece is completed, the loading and unloading module moves downward to drive the discharge channel Before reaching the workpiece chuck, the compressed air blows out the workpiece through the blowing head. This structure uses the pneumatic principle that the compressed air pushes the workpiece to move in the air pipe, so as to realize the storage, loading and unloading and blowing of the workpiece in the air pipe; thus effectively improving the PC spherical surface processing. Machine automation. The workpiece is finished to be an optical fiber ceramic ferrule. The present invention solves the problem of automatically processing the spherical surface of the small cylinder end, the inner hole of the small cylinder end surface and the chamfering of the inner hole of the small cylinder end surface of the optical fiber ceramic ferrule by the above technical means. The structure design is reasonable, the degree of automation is high, the processing precision and work efficiency are high, and the processing method is feasible; it is suitable for the processing of the small cylindrical end of the optical fiber ceramic ferrule and the improvement of similar products.
