What types of components can be inspected by the Bleeder Screw Inspection Machine?

The machine can inspect automotive bleeder screws, cross-hole screws, cone-shaped precision components, machined parts with internal holes, and small turned parts requiring hole or thread verification.

What dimensions can the Bleeder Screw Inspection Machine check?

The machine can check overall height, cone angle, outer diameter, major diameter, minor diameter, thread presence or absence, concentricity, and part length.

What defects can the machine detect?

The machine can detect cone surface damage, head damage, thread cracks, thread dents, burrs, sharp edges, dirt marks, shank damage, head cracks, surface dents, and bottom surface defects.

Can the machine inspect cross holes and internal hole continuity?

Yes. The machine can perform cross-hole presence and absence inspection, hole continuity testing, hole concentricity measurement, operation missing detection, and presence and absence verification.

Can the machine perform 360° surface inspection?

Yes. The machine uses multiple inspection stations to inspect the top surface, outer surface, bottom surface, and cone surface, enabling complete 360° inspection of the component.

How does the machine perform automatic sorting?

The machine uses an intelligent OK–NG dual-ejection system to automatically separate accepted and rejected parts after dimensional, hole, and surface inspection.
