Custom Magnetic Deburring Machine for CNC Machined Parts

Magnetic Deburring Machine for CNC Machined Parts

-- Steady & Reliable Manufacturer --

Introduction

CNC machining creates burrs at hole entries and exits, thread starts, cross-drilled intersections, milled edges and groove corners. Removing them by hand takes time, and results vary between operators. A magnetic deburring machine for CNC machined parts handles this step in a short, repeatable wet cycle.

Fine stainless steel pins driven by a rotating magnetic field enter threads, cross holes and micro grooves, removing burrs and lightly rounding sharp edges. Material removal is minimal, so tolerances on critical features are normally kept. The finished part is clean and ready for inspection, plating or assembly.

Key points:

  • Features cleaned: hole intersections, thread starts, slots, flats and milled pockets.
  • Materials: aluminum, stainless steel, titanium, brass, copper and tool steel.
  • Part types: valve parts, fittings, shafts, pins, small housings and fasteners.
  • Result: burr-free edges with a bright, uniform surface.

Application

CNC shops use magnetic deburring to finish parts that are difficult to reach with tools.

  • Hydraulic and pneumatic components: clean cross holes and port intersections inside valve bodies.
  • Turned parts and pins: remove burrs from grooves, chamfers and cut-off edges.
  • Medical and dental screws: finish small threaded parts after machining.
  • Electronic housings: clean milled edges and small tapped holes.
  • Automotive prototypes and small series: deburr diverse parts without custom fixtures.
  • Swiss-type machined parts: finish very small components in bulk.

Because no fixtures are required, mixed batches of different CNC parts can often be processed together after a short test.

Advantages

  • Reaches hidden burrs: pins flow into cross holes and threads that tools cannot reach.
  • Protects tolerances: gentle action with minimal material removal.
  • Saves inspection time: consistent edges reduce rework and rejections.
  • No custom fixtures: load parts loosely, set time and speed.
  • Handles tough materials: works on titanium and stainless as well as soft aluminum.
  • Cleaner parts: water-based process leaves parts free of dust and loose chips.

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 CNC cross holes and threads Reaches inner intersections Limited inside small holes Needs special tools per feature

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.

Sample processing is available, so you can check results before placing an order.

FAQ

  • Q: Can the machine deburr cross holes inside CNC machined parts?
  • A: Yes, as long as the hole diameter is larger than the pin diameter. Pins as small as 0.2 mm can enter small holes, and the liquid flow carries them through the intersection.
  • Q: Will the magnetic process damage threads?
  • A: No. The pins clean burrs from thread starts and ends without altering the thread form. We still suggest a gauge check on the first trial batch.
  • Q: What surface finish can I expect after deburring?
  • A: Parts typically leave with a clean, bright and slightly satin surface. A finer pin and longer time give a smoother finish. We can supply sample results on request.
  • Q: Can I mix different CNC parts in one batch?
  • A: It is possible when sizes and materials are similar. Very small and large parts should be separated, because small parts may be trapped in the pin bed.
