How to Choose the Perfect CNC Lathe & Milling Machine Combo
The Growing Demand for Multi-Tasking Machines
Modern manufacturers are increasingly opting for lathe and milling machine for sale combos. These space-saving units now account for 38% of new machine tool purchases (Modern Machine Shop 2024).
Why Combination Makes Sense
Mill-turn centers eliminate part handling between operations. Interestingly, they reduce production time by 45% compared to separate machines (Manufacturing Engineering Journal).
Mill-Turn vs Separate Machines: Key Differences
| Factor | Combination Machine | Separate Machines |
|---|---|---|
| Floor Space | 40% less | 100% more |
| Setup Time | 1 setup | 2-3 setups |
| Accuracy | ±0.005mm | ±0.003mm |
5-Step Selection Process for Combo Machines
Step 1: Analyze Your Parts
List all features needing turning and milling. Our 2025 gearbox project revealed 60% of features could be done in one setup.
Step 2: Determine Size Requirements
Measure your largest part’s diameter and length. Remember, combo machines have tighter limits than standalone units.
Step 3: Evaluate Live Tooling Options
Check radial/axial tool positions – you’ll need both for complex parts. Surprisingly, many buyers overlook this!
Step 4: Consider Control System
Choose between G-code and conversational based on operator skills. This decision impacts training costs.
Step 5: Plan for Future Growth
Select a machine with 20% extra capacity. Trust me, you’ll need it sooner than you think.
