Custom Magnetic Deburring Machine for Metal Stamping Parts

Magnetic Deburring Machine for Metal Stamping Parts

-- Steady & Reliable Manufacturer --

Introduction

Metal stamping leaves burrs on blanked edges, pierced holes, slots and bend lines. These burrs cut hands during assembly, interfere with mating parts and cause plating or coating defects. A magnetic deburring machine removes them in a wet, controlled process without changing the shape of the part.

Our magnetic deburring machine for metal stamping parts uses a rotating magnetic field to move thousands of fine stainless steel pins around the workpiece. The pins reach inside small holes, narrow slots and tight corners that vibratory media and brushes cannot reach, and a typical batch is finished in 10 to 40 minutes.

Key points:

  • Burr types handled: blanking burrs, piercing burrs, edge roll-over and fine slivers on stamped edges.
  • Materials: stainless steel, carbon steel, copper, brass, aluminum and phosphor bronze.
  • Part types: terminals, connector shells, springs, shims, washers, lead frames and thin brackets.
  • Batch handling: load by weight or by basket, then unload and rinse.

Application

This machine is used wherever stamped parts need clean, safe edges before assembly, plating or inspection.

  • Electrical terminals and connectors: removes burrs from contact fingers and piercing holes to protect mating surfaces.
  • Precision springs and clips: cleans edge burrs without distorting thin sections.
  • Lead frames and shims: deburrs fine features where manual work is not practical.
  • Automotive stampings: prepares small brackets, sensor parts and fastener plates for coating.
  • Electronic housings and shields: removes edge burrs that can scratch boards or enclosures.
  • Hardware and fasteners: improves edge quality on washers, clips and small plates.

If your stamping line produces small lots with many part numbers, a magnetic machine is a flexible way to avoid separate deburring tooling for each job.

Advantages

  • Reaches blind and fine features: pins enter holes down to about 0.3 mm that other methods miss.
  • Protects thin parts: no hard media impact, so thin stampings keep their flatness.
  • Cuts labour: one operator can run several machines while replacing hand filing.
  • Repeatable results: the same time and speed settings give the same finish each batch.
  • Low running cost: water, a small amount of liquid and occasional pin replacement.
  • Compact footprint: bench-top and floor models fit next to the press line.

Comparison with Other Deburring Methods

Factor Magnetic Pin Deburring Vibratory or Barrel Finishing Manual Deburring
Access to small holes and slots Excellent, fine pins enter micro features Limited, media is often too large Depends on operator and tools
Typical cycle time 10 to 60 minutes per batch Several hours per batch Minutes per part, labour heavy
Consistency between batches High, controlled by time and speed Medium Varies by operator
Risk of part-to-part damage Low, parts are held in the pin bed Higher, parts can collide Scratches and over-removal possible
Labour requirement Low, load and unload only Low High
Fit for stamping burrs Removes roll-over and fine slivers well Good for large burrs, weaker on small holes Slow on high volumes

Buyers usually compare cycle time, access to small features, running cost and consistency. Send us a sample and we can show how the process performs on your own parts.

Payment and Shipping

We aim to make ordering and delivery simple for overseas buyers. The terms below are typical and can be adjusted to your project.

  • Payment terms: T/T (30% deposit, balance before shipment), L/C at sight for qualified orders, and PayPal or Western Union for samples and small orders.
  • Trade terms: EXW, FOB, CIF and DDP are available on request.
  • Lead time: Standard models usually ship within 5 to 10 working days. Customized machines take about 15 to 30 working days.
  • Packaging: Machine is wrapped in protective film and packed in a strong wooden case with foam, suitable for export.
  • Shipping methods: Sea freight, air freight and express (DHL, FedEx, UPS) to most countries.
  • Shipping documents: Commercial invoice, packing list, certificate of origin and, where applicable, CE Declaration of Conformity.
  • Warranty and support: 12-month warranty on the machine, spare parts supply, English manual and remote video support.

Please send your part drawing or sample so we can recommend the right model and quote shipping.

FAQ

  • Q: What burr height can the machine remove on stamped parts?
  • A: It works best on fine and medium burrs, typically up to about 0.1 mm. Very heavy burrs should first be reduced by adjusting the stamping die clearance; we can test your sample to confirm.
  • Q: Will the process change the dimensions of my stamped parts?
  • A: Material removal is minimal and limited to the burr and sharp edge, so critical dimensions are normally unaffected. We recommend a trial on a few parts and measuring before and after.
  • Q: Can I process non-magnetic metals such as brass or aluminum?
  • A: Yes. The pins are magnetic, not the parts. The pins move through the liquid and work on any metal, including non-magnetic ones.
  • Q: How do I choose the pin size?
  • A: Smaller pins reach smaller holes and give a finer finish. Larger pins remove heavier burrs faster. Most stamping customers start with 0.5 mm to 0.8 mm and adjust after a test run.
