Short Answer
Swiss-Type CNC Lathes operating cost is not only power or consumables. Calculate cost per good part or productive hour from investment, financing, material, energy, tooling, labor, maintenance, scrap, downtime and support.
Investment and capital
Spread purchase, site work, tooling, software, training and financing over realistic utilization, not theoretical maximum output.
Variable operating cost
Complex equipment without enough volume or programming capability can increase setup time and cost. Bar quality also affects feeding and stability.
Productivity and utilization
Review bar diameter and straightness, tool capacity, simultaneous operations, part collection, coolant, chip removal and in-process measurement.
Quality and scrap
Value appears in slender parts, tight tolerances, multiple operations and sufficient repeat volume to absorb setup and programming.
Maintenance and downtime
Trial a representative part and calculate parts per hour, setup, tool consumption, rejection and operator intervention.
Decision equation
Cost per good part equals all relevant period costs divided by accepted parts. Stress-test utilization, exchange rate and downtime.
Frequently Asked Questions
What is the best cost unit?
Good part, good metre or productive hour according to the process.
Is catalogue consumption enough?
No. Use trials, actual readings and an operating range.
How often should cost be updated?
Monthly or after material, currency, utilization or downtime changes materially.
