Evaluate cutting performance using consistent materials and operating conditions. Useful measurements include cutting time, usable cutting length, edge finish and wear; a percentage gain without a baseline is not a reliable comparison.
Set a fair comparison
Use the same material batch, machine, cut depth and approved cooling method. Record each blade reference and starting condition. Do not change speed outside the equipment or blade limits to make one sample appear faster.
Record both speed and quality
A fast cut is not necessarily a good cut if it produces unacceptable chips or requires rework. Note edge condition, cut accuracy, vibration and how behaviour changes as the blade wears.
Translate results into purchasing decisions
Compare the cost of acceptable completed work, not just disc price. Send the test record and material details to the supplier when requesting a revised specification or approving a repeat order.
Build a usable trial record
For each run, record the sample reference, material batch, material thickness, cut length, elapsed cutting time and accepted length after inspection. Add photographs of the finished edge and a note about any interrupted runs. Keep rejected work separate from accepted work, and explain why it was rejected. Repeat the comparison before drawing a purchasing conclusion from one unusually good cut.
Calculate cost per accepted metre
Blade cost per accepted metre equals blade purchase cost divided by the accepted cutting length achieved over its service life. For illustration only, a blade costing 20 currency units and producing 100 accepted metres has a blade cost of 0.20 per metre. This is a calculation example, not a Zhanyue performance claim. A short sample trial cannot establish full service life; label interim results accordingly. Add labour, rework and downtime separately when comparing total production cost.
Keep interim results separate from lifetime results
A short trial can compare the observed finish and cutting behaviour. It does not establish full service life unless the test actually measures that outcome.
| Trial field | Record |
|---|---|
| Sample and revision | Model, batch where available and specification reference |
| Input | Material batch, thickness and machine |
| Work completed | Total length and accepted length |
| Quality | Rejection reason and representative edge photographs |
| Status | Interim trial, stopped for investigation or completed service-life evaluation |
