brake-disc blanking and servo-feeding page
Brake-disc blanking needs the actual stock form, blank/nesting geometry, support, die and roundness/flatness inspection; it is separate from backing-plate progressive stamping.
Scope and Evidence Status
This URL is written as a bounded technical decision page for NC servo feeding for automotive brake-disc blanking. It does not claim a confidential customer result, certified finished product or universal machine capability. Any future case-study statement needs the records listed below.
Application-Specific Process Route
The labeled route below is a conceptual engineering diagram—not a photograph of a delivered project. It makes the current page intent visible without presenting generic equipment images as application proof.
Inputs to Freeze Before Selection
- Brake-disc blank drawing and whether the route is coil-fed
- Material grade, strength, thickness, width and surface
- Blank diameter/profile, nesting, bridge scrap and edge margin
- Feeder capacity, support tables, straightening and die handling
- Press window, pitch, lubrication and scrap/blank discharge
- Burr, flatness, profile/roundness method and traceability
Context Images and Their Limits
Engineering Decision and Verification Table
| Decision gate | How to verify | Required record |
|---|---|---|
| Stock route | Confirm coil-fed feasibility and support layout | Approved process map |
| Nesting | Publish the actual geometric calculation and assumptions | Layout file |
| Traction/support | Observe slip, sag and surface through trial | Material-path record |
| Blank result | Measure drawing-defined disc-blank criteria | Inspection report |
Page-Specific Method
Work through the four gates below with the production drawing, material and real machine interface. Each gate produces a record that can be independently reviewed instead of relying on a generic industry claim.
Stock route
Confirm coil-fed feasibility and support layout Record: Approved process map
Nesting
Publish the actual geometric calculation and assumptions Record: Layout file
Traction/support
Observe slip, sag and surface through trial Record: Material-path record
Blank result
Measure drawing-defined disc-blank criteria Record: Inspection report
Failure Modes, Stop Conditions and Boundaries
- Backing-plate template reuse: Keep disc blanking as a distinct process
- Roundness attribution: Do not credit feeder motion for die-generated roundness
- Heavy-stock support loss: Stop on sag, slip or unsafe blank discharge
Acceptance Record for This Page
Freeze the released drawing and material revision, machine configuration, interface list, recipe, sample plan and measuring method. Record exceptions and the safe restart route. A publishable result must identify the tested configuration; otherwise retain this page as an engineering guide.
