When a buyer compares a CNC carbide circular saw with a band saw, the first number they see is the machine price. That number is almost never the one that decides the project. What decides it is cost per cut — the fully loaded cost of one finished, burr-free bar — calculated across blade wear, cycle time, kerf scrap, labour and capital. This guide gives production planners a working TCO model and a side-by-side worked example so the choice between a high-speed circular saw и горизонтальная ленточная пила comes out of the spreadsheet, not the showroom.
A carbide circular saw can cost two to three times a comparably sized band saw, yet on a high-volume line it is often the cheaper machine per part. The reason is throughput and scrap. At 10,000–30,000 cuts per month the band saw’s lower capital is buried under slower cycle times, wider kerf loss and more frequent blade changes. At low volume the maths flips. The only way to see which side you are on is to model the total cost of ownership (TCO) per cut, not the invoice.
Every sawing cell has the same five cost buckets. Miss one and the model lies:
| Bucket | What it captures | Circular saw | Ленточная пила |
|---|---|---|---|
| Blade / tooling | TCT disc or bi-metal blade, cost per metre cut | Higher blade price, very long life | Cheap blade, shorter life |
| Cycle time | Cut + index + clamp per piece | Fast, 2–6 s/section | Slow, 15–60 s/section |
| Kerf / scrap | Material lost to the cut width | ~2–3 mm (thin) | ~1.2–1.6 mm (thinner) |
| Labour | Loading, unloading, tending | Often lights-out | Often attended |
| Capital & power | Machine cost, depreciation, kWh | Higher capex | Lower capex |
A CNC carbide circular saw runs a TCT or PVD-coated disc at surface speeds of 80–250 m/min. Its edge is speed and finish: a 50 mm bar is severed in seconds, the cut face is flat, and downstream operations (chamfering, threading, welding) need little or no facing. For parts that ship by the tens of thousands — axle blanks, fastener stock, hydraulic rod — the labour and facing savings dwarf the blade cost. We cover blade life in detail in our guide to maximizing TCT blade life and tonnage output.
For lighter sections, the ККС-70Б и ККС-90С give the same economics at smaller diameters; for tubes the ККС-100Б is a common pick.
A горизонтальная ленточная пила runs a continuous bi-metal or carbide-tipped blade at 30–90 m/min. Its edge is flexibility and low capital: one machine cuts Ø20 to Ø400 mm with a blade change, and the blade itself is cheap. The trade-off is speed and a rougher cut face that usually needs a facing or chamfering pass. On low-to-medium volume, or where the section size swings wildly week to week, the band saw is the rational buy. The G4265ZA adds miter capability; the BSVP530 pushes band-saw speed to near-circular territory for mid volumes.
Same job, two machines, fully loaded. Assumptions: steel €0.9/kg, 40 mm cut length, 250 working days, 3-shift operation, power €0.15/kWh. Figures are illustrative planning numbers, not a quote.
| Line item | Circular saw (KCS-120B) | Band saw (GZ4265) |
|---|---|---|
| Cycle time | 4 s | 28 s |
| Blade cost / cut | €0.05 | €0.03 |
| Kerf scrap / cut | €0.10 | €0.07 |
| Labour / cut | €0.02 (lights-out) | €0.12 (attended) |
| Capital recovery / cut* | €0.18 | €0.06 |
| Estimated cost / cut | ≈ €0.35 | ≈ €0.28 |
*Capital recovery spreads machine price + interest over 5 years at the stated volume. At this volume the band saw wins on price, but the circular saw’s speed frees a cell for higher-value work — a benefit the table cannot show. Drop volume to 2,000 cuts/month and the band saw’s advantage widens; raise it to 30,000 and the circular saw pulls ahead on labour and facing alone.
Kerf is the steel you pay for and then throw away. A band saw removes less material per cut (≈1.4 mm) than a carbide circular saw (≈2.5 mm), so on expensive alloy or stainless the band saw’s thinner kerf can offset its slower cycle. On cheap carbon steel the difference is noise. The lever most planners miss is blade selection: a TCT circular blade или M42 bi-metal band blade changes cost-per-metre more than the machine choice does.
| If your line is… | Pick | Why |
|---|---|---|
| > 15,000 cuts/mo, tight tolerance | Circular saw | Speed + flat face + lights-out labour |
| < 3,000 cuts/mo, mixed sections | Ленточная пила | Low capex, one blade covers all sizes |
| Expensive alloy, low volume | Band saw + thin kerf | Material saved beats speed lost |
| Tubes / profiles, burr-critical | Circular saw | Clean edge, less deburr downstream |
| Large billets Ø300+ mm | Band saw / forge cut | Disc size & power limited above this |
At high volume, yes — the faster cycle and lower labour per part usually beat the band saw’s cheaper blade and thinner kerf. Below a few thousand cuts a month, the band saw is usually cheaper. Model it; do not assume.
Labour and downstream facing. A slow cut that needs an operator and a facing pass costs more than the blade ever will. Automation and a flat cut face are where circular saws win.
On carbon steel, barely. On stainless or nickel alloy at any volume, the thinner band-saw kerf saves real money — often more than the machine-price gap.
Take the blade price, divide by its total metres of cut life at your material/speed, then multiply by cut length. A M51 band blade или PVD-coated TCT raises life enough to change the answer.
A band saw, almost always — section sizes swing daily and capex must stay low. Add one circular saw only when a repeat contract clears the volume threshold.
Yes. Send us your section, material, monthly volume and tolerance and our engineers return a cycle-time and cost-per-cut comparison across both methods.
Cost per cut is the only number that survives contact with a real production plan. Build the five-bucket model, run your own volume through it, and the circular-vs-band-saw decision stops being a guess. For high, steady volume the Циркулярная пила с ЧПУ pays for itself in labour and scrap; for mixed, lower volume the band saw stays the smarter buy.
