Magnetic Polishing Machines for Small Parts
Inovatec supplies magnetic polishing machines that move magnetically responsive stainless steel pins through a compatible liquid process. Pin finishing can reach features that larger media cannot access, but access alone does not establish burr removal or a mirror finish. Evaluate the metal, burr condition, holes and slots, part weight, and required surface before selecting the machine.
The listed YH360D specifications are a 500 × 500 mm barrel, 2.2 kW power, and AC 220 V supply. The page describes 6–10 kg of parts with 1–2 kg of pins. Confirm usable loading, part movement, and the supplied electrical configuration before ordering.
The listing gives a 290 × 170 mm barrel, 30 kg machine weight, 500–4000 rpm speed range, and 110–220 V supply options. The stated 1.3 kg capacity includes parts and pins. Confirm the exact model, combined charge limit, and approved operating range.
A compact option for small jewelry batches. The listing specifies a 100 × 90 mm barrel, 2000 rpm, and a 400 g capacity reference. Confirm whether the quoted load rating includes the pins and the permitted part geometry.
A medium-size option listed for jewelry and suitable brass components, with a 180 × 100 mm barrel, 2000 rpm, and a 600 g capacity reference. Confirm the combined load rating and process compatibility for the intended parts.
Applications to Evaluate with Your Parts
Evaluate light burrs and surface brightening on suitable zipper components. Check small features for trapped pins and inspect functional clearances after the trial.
Review ring and jewelry finishing with the actual alloy and starting condition. Settings, stones, plating, and delicate details require a separate compatibility check; pin finishing does not remove every scratch.
Assess cleaning or brightening without assuming that pins can reach every coil surface. Check entanglement, deformation, residual pins, and the spring’s functional requirements.
Evaluate small pen tips and fittings against surface and dimensional requirements. Inspect fine passages for retained pins and confirm that the process does not affect assembly or flow.
Process trials can evaluate suitable small screws and bolts. Define thread geometry, allowable stock removal, surface cleanliness, and traceability. Appearance alone does not establish acceptance for a medical application.
Assess pin access to internal features in brass fittings. Match pin dimensions to threads, bores, and cross-holes, then check separation, cleanliness, and any change to critical dimensions.
Stainless Steel Pins for Magnetic Finishing
Use stainless steel pins specified for magnetic finishing; the stainless steel name alone does not establish magnetic response. Select pin diameter, length, charge, and compound for the machine and part. Plan pin separation, cleaning, inspection, and storage, and check components for retained pins before releasing the batch.
- Send drawings or samples, material, dimensions, weight, and the incoming surface condition.
- Define the target finish, critical features, and permissible dimensional changes.
- Include batch quantity, required output, available utilities, and handling requirements.
- Agree on equipment, consumables, sample acceptance, and the quoted supply scope.
- Factory
- Before & After
The minimum order quantity is one machine. Tell us your parts and production requirements so we can specify the appropriate model and accessories.
Machines are packed in wooden cases. Confirm the case dimensions, handling points, and any destination-specific requirements for wood treatment when arranging shipment.
Our standard terms are a 30% advance payment and the remaining 70% before shipment. A sight letter of credit may be arranged for larger orders. Other payment methods and any factory inspection should be agreed before ordering.
The listed reference lead time for standard equipment is 15–25 days. The confirmed schedule depends on the model, quantity, electrical supply, and customization. Ask for an order-specific manufacturing and shipping schedule.
Shipment can be arranged through Shanghai or Ningbo. Yiwu logistics arrangements and other departure routes can be discussed with your forwarder. Confirm the departure port, destination, and delivery terms in the quotation.

What is magnetic pin finishing?
The machine’s magnetic action moves magnetically responsive pins in a compatible liquid around suitable workpieces. This produces contact for cleaning, light deburring, or brightening, depending on the part and process. It is not interchangeable with abrasive rock tumbling or every vibratory operation.
Which features can the pins reach?
Small pins may access bores, slots, and recessed surfaces that larger media cannot reach. Access depends on pin dimensions, movement, and the complete geometry. Blind holes and cross-holes also create lodging and separation risks, so inspect the trial parts internally.
Can it remove all burrs?
No universal burr-removal claim is appropriate. Light burrs may respond to the selected process, while heavy burrs or deep machining marks may need another preparation method. Specify burr location, height, thickness, edge limits, and inspection before evaluating the finishing result.
How should stainless steel pins be selected?
Specify pins intended for the machine’s magnetic system, including their magnetic response, diameter, length, surface condition, and charge. Stainless steel grades differ; ordinary stainless steel balls or pins are not automatically suitable magnetic polishing media.
What does a typical process include?
Check the machine, container, approved loading, pins, water, and compatible compound. Secure the container and use the approved settings. After processing, separate pins, rinse and dry parts as required, and inspect the result. Follow the supplied manual for loading and operation.
Can jewelry be processed?
Suitable silver, gold, or other jewelry components can be evaluated by trials. Review the alloy, soldered joints, settings, stones, plating, and starting surface. Pin contact can brighten accessible areas, but it does not automatically remove deep scratches or create a mirror finish on every surface.
What determines operating cost?
Consider the equipment, pins, compound, water, energy, separation, cleaning, drying, and operator handling. Compare cost per accepted batch rather than assuming a desktop or industrial machine is always cheaper to run. Include cleaning and changeover between different materials.
How should aluminum parts be evaluated?
Use a compound compatible with the actual aluminum alloy and assess the contact action through short, controlled trials. Inspect appearance, edges, dimensions, and any lodged pins. A material’s low weight does not, by itself, determine the necessary process time.
Can stainless steel achieve a mirror finish?
Define the required surface measurement and visual standard. The starting texture, alloy, geometry, pins, and process determine the result. Magnetic pin finishing may be a stage in a broader finishing route; substantial machining marks may require abrasive preparation or another polishing method.
Can the process remove scratches from gold?
Evaluate the depth and location of the scratches, the alloy, and any delicate features. Brightening can make a surface look cleaner without removing a deep scratch. Use an approved compound and inspect sample parts before specifying the process for valuable components.
How is the machine size selected?
Compare part dimensions, total part and pin charge, required movement, and accepted batch output. The listed YH360D and KT capacities use different load descriptions; confirm the charge limit for the chosen model. Include separation, inspection, and drying in the production calculation.
