300L OBD-ZL300C Vibratory Finishing Machine with Separator is listed in the SurfacePolish equipment catalog. Machine selection should begin with the workpiece problem, required finish, part geometry and the inspection standard. The page is structured to make those questions clear before an application route is reviewed.

Start with the workpiece problem
Describe the incoming burrs, marks, residue or appearance issue and identify the surfaces that must remain protected. Add material, dimensions, part weight when known, batch context and clear photos from several angles.
- Incoming condition and target finish
- Critical edges, holes and threads
- Part movement and separation concerns
- Downstream cleaning or assembly
Review the machine route
The usable process depends on the machine configuration, media or compound, loading approach and separation method. These details should be checked against the exact workpiece rather than inferred from a product name or photograph.
- Machine family and workpiece geometry
- Media or compound direction
- Loading and unloading access
- Inspection and cleaning after processing
Plan a controlled test
Use representative parts and agree on acceptance criteria before testing. Record the starting condition, process settings that were actually used, inspection intervals, surface change and any protected feature. Keep the result tied to the reviewed part family and configuration.
- Use production-representative parts
- Inspect critical features at short intervals
- Record the process and observations
- Preserve the accepted test record
What to send for an application review
Send photos, a drawing when available, material, dimensions, target appearance, quantity, critical tolerances and any cleaning or assembly requirement. The finishing team can then identify the most useful machine and media questions for the next step.
Frequently asked questions
Does the machine name define a complete recipe? No. The machine, media and workpiece must be reviewed as one process. Can a photograph confirm the result? No. The part and agreed inspection method are needed. Is one test universal? No. Conclusions remain specific to the reviewed part family and configuration.
