## Question 1: What Is Your Tightest Tolerance?
This determines whether you need direct drive or gear reducer.
- Tighter than 0.02mm: direct drive only
- 0.02-0.1mm: either works, gear reducer saves cost
- Looser than 0.1mm: gear reducer is fine
## Question 2: What Is Your Production Volume?
This determines whether the servo premium pays off.
- Above 1M parts/year: servo ROI is typically under 2 years
- 500K-1M parts/year: servo ROI is 2-4 years, usually justified
- Below 500K parts/year: evaluate carefully, mechanical press may be better value
## Question 3: What Materials Will You Form?
- Mild steel, aluminum: any servo press works
- HSS 590-780MPa: servo strongly recommended for springback control
- UHSS 980MPa+: servo required
- Titanium, Inconel: servo required, plus specialized tooling
## Question 4: What Is Your Maintenance Capability?
Servo presses require technicians who can work with servo drives (Siemens, Yaskawa, Fanuc, Mitsubishi). If your maintenance team has no drive experience, factor in training cost or service contract.
## Question 5: What Is Your Lead Time?
New servo presses: 6-18 months depending on manufacturer and size.
If you need a press in 3 months: used servo press or mechanical press are your options.
If you have 12+ months: order new, specify exactly what you need.

Good buying guide. I'd add one more question: what is your die change frequency? If you change dies more than twice per shift, the servo press HMI setup time matters a lot. Some brands have much faster job recall than others — worth asking for a demo of the die change workflow before buying.
