3. Cost Comparison

This section compares both machine types across key cost factors.

Machine Investment

Faster machines typically cost £60k–£300k+ depending on speed and automation.
High precision machines typically cost £120k–£400k+, due to advanced control systems.

Tooling Cost

Faster machines use standard tooling, reducing cost.
High precision machines require high-precision tooling, increasing cost.

Cost per Meter Produced

Faster machines deliver a very low cost per meter.

Labour Cost

Faster machines reduce labour through automation.
Precision machines may require skilled setup and monitoring.

Scrap & Waste Cost

Faster machines may generate higher scrap rates if not optimized.
Precision machines reduce waste through consistent accuracy.

Key Insight

Speed reduces cost per unit, but precision reduces hidden costs (scrap, rework, quality issues).
