Porous drill

1. Uses and Features:

It is used for the reaming and countersinking of the spoke bolt holes.

2. Process quality requirements for porous drill products:

●The surface roughness Ra of the machined bolt holes is: 6.3.

●Accuracy tolerance of bolt hole diameter after machining: diameter tolerance≤±0.10mm, position tolerance≤0.30mm

●Production time: 2 pieces/min.

●Processing range: spoke outer diameter φ350～φ620, thickness 9～18mm, height 30～160mm

3. Process flow:

●Processing process: workpiece positioning table -- fast forward -- work advance -- reaming, countersinking hole -- fast backward -- stop -- take out the workpiece.
