Confirm what is actually being offered
Match the serial plate, model suffix, control, spindle, travels, axes, options and included accessories to the written description. Do not rely on a generic model page as proof of the exact unit.
Compare the right price
Use asking-price observations as a starting point, not as completed-sale proof. Compare machines with similar year, control generation, configuration, hours and operating condition.
Inspect under power when possible
Review alarms, spindle sound, axis motion, tool changes, coolant and chip systems, way condition, leaks, backlash, probe or rotary operation and available accuracy evidence. Use a qualified independent technician when the risk warrants it.
Read the contract
Confirm seller identity, title or authority to sell, included equipment, deposit terms, acceptance conditions, removal deadline, loading responsibility, risk of loss and available remedies. Consult an attorney when rights or obligations are unclear.
Control payment and release
Use payment terms appropriate to the transaction and your risk tolerance. Do not let the machine move before the written conditions for funds, title and release are satisfied.
Calculate production-ready cost
Add inspection, repair allowance, freight, permits, rigging, foundations, electrical work, transformers, air, coolant, tooling, workholding, software, training, commissioning and downtime.
