Coaxial Cable Jacket Notching And Cutoff Blades
Use notching and cutoff only when the approved drawing defines a real window, relief or combined end feature in a jacket-only profile or declared coaxial cable component. Do not invent a notch, and do not treat this page as universal coax stripping guidance.

Where This Cutting Application Appears
Supplied material and process stage
Separate jacket-only extrusion from a completed coaxial cable. For a finished cable, record the outer jacket, braid and foil shields, dielectric and centre conductor, plus any armour or secondary jacket. For a jacket-only profile, record the polymer, wall geometry, extrusion and cooling state. CommScope describes coaxial construction with a centre conductor, polymer dielectric and foil/braid shielding, while Belden product data show that jacket, shield and insulation materials vary by cable design; neither source defines the customer cable or a MEIRENTE tool.
Installed process checkpoint
Record feature drawing, full layer stack, notch datum and depth, cutoff length, registration, support, clamp, tool sequence, chip removal and shield, dielectric and conductor protection zones.
Output and inspection stage
Measure notch geometry, position, depth and final length; inspect corners, jacket cracking, incomplete chips, braid or foil contact, dielectric marks and conductor clearance.
Notching And Cutoff process boundary
Confirm that the supplied construction, actual machine operation and approved drawing match this process before reviewing a replacement tool.
Notching And Cutoff setup checkpoint
Record material condition, protected layers, installed interface and downstream handling before a controlled trial.
Notching And Cutoff acceptance checkpoint
Use customer-approved dimensions and observable defect limits on labelled samples from the same material lot and machine settings.
Define the Required Cut Result
- Measure notch geometry and position from the approved datum
- Measure cutoff length and end squareness separately
- Inspect jacket corners, incomplete chips and every shield and dielectric layer
- Verify centre-conductor clearance and debris removal using the customer-approved method
Problems to Diagnose Before Changing the Knife
Notch position walks relative to the cutoff end
Compare feed index, feature registration, cable slip, tool sequence and the approved datum.
Jacket cracking extends beyond the feature corner
Review corner geometry, jacket state, support and entry instead of assuming one universal cable.
Braid, foil, dielectric or conductor is contacted
Stop and verify depth, layer variation, support and the declared protected limit.

Acceptance Criteria for a Controlled Trial
Agree how the trial will be judged before changing the knife or machine setting.
- Measure notch geometry and position from the approved datum
- Measure cutoff length and end squareness separately
- Inspect jacket corners, incomplete chips and every shield and dielectric layer
- Verify centre-conductor clearance and debris removal using the customer-approved method
Knife Forms That May Be Considered
| Possible knife form | When it may be considered | What must be confirmed |
|---|---|---|
| Existing registered punch and cutoff set | For equipment already coordinating a supported feature and cable-end cut. | Confirm tool seats, stroke, sequence, counter-surface, registration and chip ejection. |
| Existing controlled-depth rotary or profile feature cutter | Only where the machine controls path and depth against the actual layer stack. | Confirm drawing, phase, depth stop, support, runout and protected-layer clearance. |
Information to Send for Technical Review
You do not need to know the exact blade name. Send the available workpiece, machine, current-knife and cut-result information so the application can be reviewed against a drawing or sample.
- Cutting object: jacket-only extrusion, finished coaxial cable or a documented cable subassembly
- Cable designation and drawing plus jacket, braid, foil, dielectric, centre conductor, armour and secondary-jacket construction
- Jacket material, outside diameter, wall-thickness range, ovality, temperature and conditioning state
- Conductor and shield materials, permitted deformation and the layers that may or may not be contacted
- Target length or feature drawing, datum, tolerances and accepted end, notch, shield and conductor limits
- Existing feed, straightener, clamp, support, holder, blade and counter-surface drawings
- Current tool plus labelled accepted and rejected pieces from the same cable lot and process stage
- Trial quantity, electrical inspection or test ownership, scrap handling, packing and annual demand

Questions About This Cutting Application
Can a blade form be selected from the term “coaxial cable jacket” alone?
No. Confirm the supplied construction, actual process stage, protected components, installed interface, current tool and accepted and rejected samples.
Does every coaxial cable jacket need a notch?
No. Only an approved feature drawing establishes this operation.
Can this page be used as a generic coax stripping specification?
No. Stripping requires explicit removal lengths, depth stops and acceptance criteria for each protected layer.
