Table Tops → Round Cutter
Architectural Stone → CNC
Blocks → Block Cutter
Step 2: Calculate Production Volume
Determine:
Daily Production
m²/day
Monthly Production
m²/month
Annual Production
m²/year
Don’t purchase a machine based only on future aspirations.
Your production plan should justify the machine investment.
