- Tub vibratory finishing for suitable camshaft geometries.
- Barrel systems assessed against usable chamber and load limits.
- Media selected for smoothing, cleaning, or burnishing.
- Trials to verify lobes, journals, dimensions, and cleanliness.
Camshaft Polishing and Finishing Machines
Inovatec reviews finishing equipment and media for suitable camshafts. Define the operation and the surfaces to be processed, including any areas that must remain protected. Machine selection starts with camshaft length, weight, material, heat treatment, lobe geometry, journal tolerances, and the required surface condition.
A tub vibratory finisher can accommodate suitable long camshafts. Review chamber clearance, supports or dividers, media movement, loading, and the required separation arrangement.
A centrifugal barrel system can be evaluated where the camshaft, media, and loading fit the selected barrel and operating limits. Confirm part restraint, permissible load, contact, and the finishing result through trials.
Camshaft Types and Process Requirements
For motorcycle camshafts, provide the lobe and journal drawings, material, treatment, and batch size. Compare equipment only after confirming the usable chamber and permitted surface changes.
Flat-tappet camshafts require controlled lobe geometry and surface condition. Agree on the processing stage and protected areas with the component specification before choosing a finishing method.
For forged-steel diesel camshafts, review length, mass, handling, journal tolerances, and the supplied heat treatment. Select a chamber and loading arrangement around the actual part.
Cast-iron camshafts require media and chemistry compatible with the specified material and surface. Check cleaning, residue removal, corrosion control, and dimensional change.
For automotive production, define the incoming surface and acceptance limits for each camshaft family. Match equipment, handling, separation, and cleaning to the required output.
For roller camshafts, protect the specified lobe profile and journal surfaces. The finishing operation must satisfy the component drawing and functional surface requirements.
Camshaft Polishing Media
Plastic abrasive grades and porcelain media serve different smoothing and burnishing tasks. Match the media grade and geometry to the camshaft material, features, surface target, and permissible stock removal. Include compound compatibility and final cleaning in the trial.
- Share drawings or representative samples and identify the material and starting surface.
- Specify the target finish, critical features, and permissible dimensional changes.
- Include required output, handling, utilities, and delivery requirements.
- Review the proposed machine, media, cleaning, and sample acceptance criteria.

- Before & After
Media is packed in double-layer plastic bags. Machines are secured on wooden pallets and enclosed in wooden cases. Confirm the packing dimensions, gross weight, lifting points, and destination requirements in the quotation.
Evaluate plastic abrasive grades for the specified smoothing task and porcelain grades for suitable burnishing stages. Check media dimensions, surface changes, residues, and the component’s acceptance requirements.
Confirm voltage, frequency, phase, current, and earthing for the selected model. The 230 V, three-phase configuration referenced for this application requires confirmation against the supplied machine documentation.
Payment options include Western Union, PayPal, and a letter of credit, subject to agreement for the order. Confirm availability and terms in the quotation.
Standard payment terms are a 30% advance payment and the balance before shipment. Confirm the agreed terms and inspection arrangements in your quotation.
Shanghai and Ningbo are available export ports. For shipments routed through Yiwu, confirm the inland transport and export arrangements. Include your destination and delivery terms when requesting a freight quotation.

Define the Camshaft Surfaces to Be Finished
Specify the material, heat treatment, manufacturing stage, lobe profile, journals, and required surface condition. Identify areas for cleaning, smoothing, or burnishing and the features that must remain protected.
Compare Chamber and Handling Options
A tub finisher can be evaluated for suitable long camshafts. Barrel equipment needs its own envelope and load assessment. Confirm support, contact, circulation, separation, and cleaning for the proposed configuration.
Select Media by Task
Plastic abrasive grades and porcelain media have different finishing roles. Choose grade, geometry, and compound around the actual material and stock-removal allowance. Inspect recesses and passages for retained media and residue.
Set Process Time from Acceptance Results
Incoming surface, required finish, media condition, load, chemistry, and equipment settings affect the cycle. Establish the process with representative camshafts and record the accepted operating conditions.
Evaluate Corrosion and Surface Damage Separately
Cleaning or finishing may remove accessible surface contamination, but corrosion pits, wear, and damaged functional surfaces need their own assessment. Agree on acceptance and rejection criteria before considering a used component for processing.
Inspect Geometry and Final Cleanliness
Inspect the agreed lobe and journal dimensions, surface condition, edge changes, and cleanliness after the trial. A polished appearance alone does not establish engine performance or service life. Send the component specification and production requirements for a process review.
