What Should I Pay Attention To When Buying a Second-Hand, Pre-Owned, Surplus, Used Anayak Anak Matic-7 CNC Vertical Machining made in Spain?
When evaluating a second-hand Anayak Anak Matic-7 CNC Vertical Machining Center (Spain), you should approach the purchase from both a technical inspection and a commercial risk perspective. This is a heavy-duty European machine, typically used in demanding applications, so condition and maintenance history are critical.
1. Machine Structure & Mechanical Integrity
- Box ways condition: These machines are known for rigid box guideways. Check for:
- Scoring, wear marks, or uneven contact
- Stick-slip movement during slow feed
- Column & bed alignment:
- Inspect for signs of crash damage or re-machining
- Table surface:
- Excessive drilling, T-slot damage, or resurfacing reduces value
Why it matters:
Structural wear cannot be economically repaired. This defines the true long-term accuracy of the machine.
2. Axis Performance & Backlash
- Perform a ballbar test or laser measurement if possible
- Check:
- Backlash in X/Y/Z axes
- Repeatability and positioning accuracy
- Listen for:
- Abnormal noise in ball screws
- Vibration during rapid traverse
Red flag: inconsistent positioning or compensation-heavy control settings.
3. Spindle Condition (Critical)
- Check:
- Spindle runout (micron level)
- Bearing noise at different RPM ranges
- Temperature rise after running
- Inspect taper:
- Fretting, scoring, or tool marks
Important:
Spindle rebuild on this class machine can be very expensive.
4. CNC Control & Electronics
- Typically equipped with Heidenhain or Fanuc (depending on version)
- Verify:
- Control boots correctly without alarms
- All axes home properly
- Parameters are backed up
- Check:
- Availability of spare parts (older controls can be costly)
- Screen, keyboard, MPG condition
Tip: Ask for parameter backup files before purchase.
5. Tool Changer & Magazine
- Check:
- Tool change cycle time consistency
- Alignment of arm / carousel
- Tool pocket wear or damage
- Run multiple tool changes:
- Look for misgrabs or delays
6. Lubrication & Hydraulic Systems
- Inspect:
- Automatic lubrication system (working or not)
- Oil distribution lines (blockages)
- Check hydraulic pressure stability
Neglected lubrication = hidden wear inside guideways and screws
7. Coolant & Chip Management
- Open coolant tank:
- Sludge buildup?
- Rust or contamination?
- Check:
- Chip conveyor operation
- Coolant pump pressure
8. Electrical Cabinet & Wiring
- Open cabinet and check:
- Dust, oil contamination
- Burn marks or modifications
- Verify:
- Cooling fans working
- No bypassed safety circuits
9. Machine History & Usage
Ask for:
- Maintenance records
- Previous application (steel vs aluminum vs mold work)
- Total working hours
Heavy steel cutting = more wear than light aluminum work
10. Test Under Power (Non-Negotiable)
Run the machine:
- Dry run + cutting test if possible
- Check:
- Surface finish quality
- Dimensional accuracy
- Vibration during load
11. Transportation & Installation Considerations
- This is a large, heavy-duty machine
- Confirm:
- Exact weight and dimensions
- Foundation requirements
- Rigging cost
12. Commercial & Legal Checks
- Confirm:
- Serial number matches documentation
- Machine is not under financing or lien
- Standard clause:
- Sold as-is, where-is, without warranty
Final Professional Advice
For an Anayak Anak Matic-7, the most critical areas are:
- Box ways condition (non-repairable economically)
- Spindle health (high-cost risk)
- Control system reliability (availability of parts)
If these three are good, the machine is usually a very strong investment due to its rigid construction and heavy-duty capability.
