Stop an unsafe trial first
A cracked plate, missing tooth, damaged tool or abnormal movement is a reason to stop using the blade and follow the machine's isolation procedure. Inspection and adjustments belong to qualified personnel working to the machine and blade documentation. Keep guards and approved clamping in use.
LEUCO's guidance requires a blade appropriate to the material and machine, a matching bore/arbor and compliance with the marked maximum speed. Do not use this guide to approve a blade or a new operating speed.
Identify the complete blade
| Field | What to record |
|---|---|
| Geometry | Outside diameter, kerf, plate thickness, bore and tooth count. |
| Mounting | Pin holes, flange requirements and the exact machine/arbor interface. |
| Application | Alloy, profile cross-section and wall thickness, single or stacked cutting. |
| Markings | Blade reference, tooth geometry and the maker's application/speed markings. |
Kerf is the cut width; plate thickness is the blade body thickness. Record both separately. A notation such as diameter × kerf/body × bore is incomplete without the tooth count and any mounting features. Confirm how the supplier labels each dimension.
Use symptoms to organize checks
| Observation | Checks to request from the technical team |
|---|---|
| Marks or burrs change across the cut | Cut alignment, workpiece support, blade condition and mounting/runout. |
| Material adheres to the teeth | Approved lubrication delivery, chip clearance and application values. |
| Tooth damage | Workholding, engagement, chip evacuation and suitability of the tooth geometry. |
| Problem appeared after regrinding or a changeover | Service history, geometry, mounting and the exact changes made. |
Hoffmann's circular-saw troubleshooting relates cutting problems to several interacting causes, including clamping, tooth pitch, coolant and feed. The table is a request for inspection, not a remote diagnosis or an instruction to change a machine setting.
What should be measured?
Ask the machine service team to check the relevant mounting faces, flange condition and runout against the manufacturer's limits. Record the method and measured result; a number without its measurement location and approved limit is not enough to accept the setup.
Do not mask a mounting problem by purchasing more teeth or a blade marketed as anti-vibration. Manufacturer examples, such as Freud's aluminum/plastics blade designs, show that application-specific features exist; they do not establish compatibility with your machine.
Make the trial evidence useful
Record machine model, blade reference, service condition, profile drawing, clamping/support arrangement, actual programmed values and lubrication. Photograph both cut faces and label the entry/exit sides. Note whether the symptom occurs on every part or only at certain profile orientations.
Compare to an accepted part using agreed criteria: cut angle, dimensional accuracy, burrs and surface finish. Keep the reference sample and service findings with the record. Do not state a tool-life gain from one undocumented trial.
Before placing the replacement order
Send the blade specification, machine model, symptom record, quantity and delivery city. Ask the quotation to confirm the proposed geometry, mounting features, intended application and any difference from the existing blade. Speeds, feed, clamping and lubrication must be approved for the actual machine/blade/material combination.
