A composite manufacturing method with extruding and turning process for extruding and turning a workpiece includes a clamping step, an isolating step, an extruding step and a turning step. The composite manufacturing method is used for manufacturing a surgical instrument. The clamping step is for positioning a clamping portion of the workpiece by a lathe chuck of the lathe apparatus. The isolating step is for blocking a lathe extruding force via an isolating portion of an extruding apparatus. The extruding step is for extruding a processing end portion of the workpiece by the extruding apparatus and generating the lathe extruding force transmitted toward a clamping portion of the workpiece. The turning step is for turning the processing end portion of the extruded workpiece by a lathe apparatus. The extruding apparatus is disposed on the lathe apparatus.

A machining system including a first body with a first channel to receive a first stream of compressed air, a second channel to receive a second stream of compressed air, an upper compartment, the first stream of compressed air configured to clear debris from an upper compartment surface and a lower compartment surface when the first stream of compressed air is engaged, the upper compartment configured to shift to a position where the upper compartment abuts the lower compartment and conceals the upper compartment surface and the lower compartment surface when the second stream of compressed air is engaged, and the lower compartment configured to shift when in contact with the upper compartment.

A device for centering a longitudinal workpiece fixed on a spindle includes a support body linearly displaced along a support body axis. The support body and support body axis are aligned substantially parallel to an axis of rotation of the spindle. A first support element movably arranged on the body supports the workpiece or a workpiece receiving part, and a second support element movably arranged on the body supports the workpiece or a workpiece receiving part. The first support element can be linearly displaced in a first direction and is rotatably arranged about a first axis of rotation on the support body and the second support element can be linearly displaced in a second direction different from the first direction and is rotatably arranged about a second axis of rotation on the support body.

A fabric cutting system and/or method can include a mandrel having a body and first and second legs, a chuck, the chuck configured to receive either one of the legs or body to rotatingly support the mandrel. The mandrel can be rotated and the fabric mounted on the mandrel can be cut about the leg at a location beyond the end of the other leg. One of the legs can include a leg extension removable from a leg base that when removed allows the other leg to be cut beyond the end of the leg base. The fabric can be cut with a cutting laser, which may be a multi-axis laser, and/or have low power.
