Buying a used CNC machine in India is the fastest way to add precision capacity without blowing your capex budget. But it can also be the fastest way to inherit someone else's expensive problem. This checklist is the long-form version of advice we hear from operators across India — distilled into a practical 8-point flow.
1. Lock the use case before you shortlist
Before opening a single listing, write down the parts you intend to make: their material, size envelope, tolerance, and expected production volume. The exercise makes the spec sheet do the work for you.
- Bed length / swing diameter for lathes
- Working envelope (X / Y / Z) for VMCs
- Spindle motor power and max RPM
- Controller (Fanuc, Siemens, Mitsubishi, Mazatrol)
- Required tooling, chuck size, tailstock travel
Skipping this step is the #1 reason teams over-buy or under-buy.
2. Understand the year vs hours equation
A 2014 machine that has clocked 8,000 hours can be in better shape than a 2018 machine that has clocked 25,000 hours under poor maintenance. Always ask the seller for both year of manufacture and hours run, ideally backed by the controller's lifetime hour log.
3. Make condition language concrete
"Good" means very different things to different sellers. On structured marketplaces like store.oldmachine.in, the seller is asked specific questions — but you should still confirm:
- Is the spindle within original taper tolerance?
- Are the ball screws and LM guides original or replaced?
- Are the way covers, bellows, and chip conveyors functional?
- Any history of crashes or major part replacements?
4. Insist on real photos and a video
Stock images and brochure photos are red flags. Ask for:
- Wide shots of the machine from at least three sides
- Close-ups of the spindle nose, turret, ATC, and control panel
- A short video of the machine powered on with the controller homing all axes
Most genuine sellers oblige quickly.
5. Check the controller and ladder backup
A surprising number of used CNC issues trace back to missing or corrupted controller backups. Ask the seller whether they have:
- The original controller parameter (parm) backup
- A ladder/PLC backup
- Tool offsets and macros
If these are missing, plan for retrofit or commissioning support before you buy.
6. Verify the seller as carefully as the machine
OldMachine verifies seller business identity (e.g. GSTIN) before listings go live, but you should still:
- Confirm the seller's business address and reachability
- Ask for an in-person inspection (most genuine sellers welcome it)
- Verify GSTIN independently on the GST portal
- Use written WhatsApp/email trails for important commitments
7. Plan logistics before you transfer money
Industrial machinery transport is non-trivial. Before signing the deal:
- Confirm dismantling, loading, transport, unloading, and re-leveling responsibility
- Get a quote from a transporter who has handled similar machines
- Build a buffer for foundation rework if your floor isn't ready
8. Phase the payment
Standard practice in the Indian used machinery market:
- Token amount on agreement
- Larger tranche after physical inspection
- Final balance on machine reaching your floor and powering on
A reputable seller has no problem with this structure.
Final word
OldMachine is the discovery and conversation layer — inspection and the actual transaction are between you and the seller. That's by design. Use this checklist to make the conversations sharper and the decisions safer.
