Custom Neodymium Disc Magnets Made to Drawing

Custom sintered NdFeB disc magnets made through a drawing-led review. Dimensions, grade, coating, magnetization and tolerance stay connected to the part and its application.

PDF, STEP or STP drawing preferred. A written description can start the discussion when a drawing is not ready.

ENGINEERING SNAPSHOT

Define the project inputs before production review.

01 / GEOMETRY AND DRAWING INPUTS

Define the geometry.

A disc magnet requirement starts with the outside diameter and thickness, then adds the faces, edge condition and fit details that matter in the assembly.

  • 01Diameter and thickness
  • 02Hole or recess, when applicable
  • 03Edge, chamfer and surface requirements
  • 04Critical fit, clearance or concentricity needs
  • 05Magnetization direction and polarity
  • 06Quantity and annual usage

02 / MATERIAL AND APPLICATION

Engineering decisions.

Grade, coating, magnetization and temperature context should be reviewed together rather than selected as isolated catalogue fields.

Finished magnet quality evidence supporting grade and coating decisions
PRODUCT FINISH / TECHNICAL SUPPORT
  1. 01Grade

    Review the material range and temperature context against the application and drawing.

    Review grade guidance ↗
  2. 02Coating

    Select the surface treatment with the operating environment, fit and dimensional allowance in view.

    Review coating options ↗
  3. 03Magnetization

    Carry the reference face, polarity and required direction with the drawing or written requirement.

    Define magnetization ↗
  4. 04Temperature

    Keep operating conditions connected to grade, coating and the intended assembly context.

03 / DRAWING TO FINISHED DISC

From drawing to finished disc.

Diameter, thickness, edge condition and critical fit or clearance requirements should be identified on the drawing. Tolerance is defined around the feature, fit and production route that matter to the application.

01DrawingApproved geometry, references and critical dimensions
02MachiningThe production route follows the features that control fit

04 / RELEASE EVIDENCE

Release evidence.

Before release, the checks should answer what the disc must do in the assembly and what the drawing requires.

  1. 01DimensionalCritical dimensions and fit requirements are checked against the requirement.See dimensional inspection ↗
  2. 02MagneticMagnetic performance is reviewed with grade and application context.See magnetic testing ↗
  3. 03Surface / coatingSurface condition and coating expectations stay part of release.See coating inspection ↗
  4. 04TraceabilityQuality records can be included in the quotation basis.See traceability ↗
See Quality and Inspection

05 / APPLICATION CONTEXT

Application context.

Disc geometry becomes reviewable when the supplier can see the assembly, environment and release questions around it.

06 / WHAT TO SEND

What to send.

Bring the requirement you have. Not sure is acceptable; the review can start from partial requirements.

  • 01Drawing, if available
  • 02Diameter and thickness
  • 03Grade and coating, if known
  • 04Magnetization direction, if known
  • 05Quantity and application
  • 06Quality or inspection requirements
