THE COMPLETE DECISION

An inspection should answer the purchase question, not produce an impressive checklist with no acceptance standard. Define access, tests, evidence and limits before the visit.

IdentitySerial, control, configuration, options and included property

ConditionVisual, power-on, functional and maintenance evidence

GeometryNamed tests, instruments, conditions and acceptance basis

BoundaryExcluded systems, inaccessible areas and unresolved questions

Confirm identity first

Match manufacturer, model, serial, year, control, option records and data plate to the offered machine. Record what is installed, what is disconnected and which accessories or software are included.

Define operating access

State whether the machine can be powered, warmed, jogged, run through tool changes, demonstrate spindle speeds, execute a test program or cut material. A static visual review and a production demonstration support different conclusions.

Choose tests around risk

Geometry, backlash, spindle condition, axis load, alarms, coolant, chip handling, probing, rotary systems and safety devices can require different tools and time. The inspector should state method, observed condition and limitations rather than imply complete coverage.

Connect inspection to the agreement

Specify who pays, who may attend, safety rules, confidentiality, damage responsibility, acceptance criteria, cure rights and what happens if access or condition differs from the offer. Preserve dated photos, reports and machine state.

START THE REQUEST

Give us enough context to make the next step useful.

The request is reviewed by email. MBB may provide research, identify a direct source or offer a permission-based introduction when a relevant provider path is available.

Independent by design.

MBB does not certify machine condition. We can organize an email-first request and identify independent provider paths when available and authorized.

Evidence before acceptance

Verify identity, condition and the proof behind the listing.

An inspection begins with the exact machine and a defined evidence request. Continue with the guides behind serial matching, current operating proof and condition-based value.

Buyer intelligence · 22.5 secondsSame machine. Three listings.Match the serial number, condition, location and seller authority before treating multiple listings as separate machines.Watch and continue the research →

Condition and value · 22.5 secondsUsed does not mean used up.Evaluate condition, maintenance, controls, support and upgrade costs instead of relying on machine age alone.Watch and continue the research →
