HMT Milling Machine Solutions: CNC Automation for Factories
Why Indian Factories Are Automating HMT Mills
Facing labor shortages and quality inconsistencies? Modernizing HMT milling machine units with CNC automation can increase output by 40% (Indian Machine Tool Manufacturers’ Association 2024). Our team’s automation project at a Mumbai auto parts plant saw ROI in just 14 months.
even 20-year-old HMT machines can be retrofitted with new controls. Their cast iron construction provides perfect vibration damping for precision work.
Manual vs Automated HMT Mills: Productivity Showdown
| Metric | Traditional FN2V | CNC-Retrofit FN2V |
|---|---|---|
| Parts/Hour | 8-10 | 18-22 |
| Operator Needed | Constant | Periodic checks |
| Accuracy | ±0.05mm | ±0.02mm |
| Setup Time | 45-60 mins | 10-15 mins |
| Energy Use | 6.5kW | 7.2kW |
5-Step Automation Process for HMT Machines
⚠： Rushed retrofits cause 80% of automation failures (Factory Automation Journal):
- Machine Assessment – Check spindle condition and ways
- Control Selection – Choose between Siemens or Indian CNC kits
- Servo Installation– Replace old leadscrews with ball screws
- Tool Changer Add-on – 6-12 station options available
- Operator Training – Minimum 40 hours recommended
Success Story: Pune Gear Manufacturer
a mid-sized gear company automated three HMT M2TR machines. The results shocked everyone:
- Overnight production became possible
- Human errors dropped by 92%
- Tool life increased 35%
3 Critical Automation Mistakes to Avoid
⚠： Watch out for…
1. Choosing cheap imported controllers (lack local support)
2. Skipping machine reconditioning first
3. Underestimating training requirements
