Custom High Precision Magnetic Polishing Deburring Machine for Small Parts

High Precision Magnetic Polishing Deburring Machine for Small Parts

-- Steady & Reliable Manufacturer --

Introduction

Small precision parts need very gentle treatment. A high precision magnetic polishing deburring machine for small parts uses very fine stainless steel pins, often 0.2 mm to 0.5 mm, to remove micro burrs and give a smooth, bright surface without altering shape or critical dimensions.

The rotating magnetic field creates a soft but thorough scrubbing action that reaches micro holes, fine threads and narrow grooves. Speed is adjustable in small steps and time is set digitally, giving the control needed for parts measured in millimetres.

Key points:

  • Small part range: from about 0.5 mm up to 30 mm in size.
  • Fine pins: 0.2 mm pins for micro holes and delicate edges.
  • Soft action: no impact, so thin walls and fine features stay intact.
  • Surface result: burr-free with a smooth, polished appearance.

Application

This machine suits industries where parts are tiny, tolerances are tight and surface quality matters.

  • Micro screws and pins: clean threads and heads in bulk.
  • Electronic connector contacts: remove burrs from small pins and terminals.
  • Watch and instrument parts: finish gears, springs and fine components.
  • Medical micro components: polish small needles, tips and fasteners.
  • Sensor and optical housings: deburr small bores and edges.
  • Swiss-machined micro parts: finish very small parts directly from the machine.

For very small lots, we recommend sending a sample set so we can match the pin size and process time before you order.

Advantages

  • Very fine control: tiny pins and precise speed steps protect delicate geometry.
  • Micro-hole access: pins reach into holes where larger media cannot enter.
  • Better surface quality: removes burrs and leaves a uniform polished look.
  • Low scrap rate: soft action avoids deformation and chipping.
  • Quick cycle: most micro parts are finished within minutes.
  • Bench-top convenience: small footprint suits labs, cleanrooms and workshops.

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 micro parts Pins as fine as 0.2 mm Media too large, parts may trap Difficult under magnification

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.

Small batches can be shipped by air or express for quick evaluation.

FAQ

  • Q: How small can the parts be for this machine?
  • A: Parts from about 0.5 mm can be processed. Parts that are smaller than the pin diameter may mix into the pin bed, so we may recommend a basket or a pin separator.
  • Q: What pin size should I choose for polishing small parts?
  • A: For fine polishing and deburring, 0.2 mm to 0.3 mm pins are common. For slightly larger parts or stronger burr removal, 0.4 mm to 0.6 mm pins work well.
  • Q: Will the machine round the edges too much?
  • A: No, rounding is limited. You can adjust time and speed to keep an edge sharp but burr-free, which is important for functional edges.
  • Q: Can the machine be used in a cleanroom environment?
  • A: The process is water-based and produces no airborne dust, so it can be used in controlled areas. Please confirm your site requirements and we will advise on a suitable configuration.
