Used Machine Inspection Checklist

Use this checklist on every used machine tool you consider. Record what you find, take photos and note anything the seller can’t or won’t show.

Identity

• Make, model, serial number and build year from the plate
• Control type and software version
• Options fitted: probing, chip conveyor, high-pressure coolant, 4th axis
• Included tooling and accessories, listed item by item

Structure and ways

• Wipers intact; no chips packed under them
• Way surfaces: scoring, rust, flaking or worn scraping marks
• Backlash on each axis measured with a dial indicator
• Even lubrication reaching the ways; lube tank not dry

Spindle

• Runs quietly at low, middle and top speed after warm-up
• Runout measured on a test bar
• No unusual heat after running
• Tool clamping and release work cleanly

Why this matters in what spindle hours tell you.

Tool changer and turret

• Cycle every pocket or station
• Watch for hesitation, banging or misalignment
• Check alarm history for changer faults

Electrics and control

• Cabinet clean and dry, no burnt smells or scorched wiring
• Cooling fans and filters working
• Parameter backup available
• Alarm history screen reviewed and photographed

Under power

Home all axes, run a warm-up, make a test cut if possible and measure the part. See why seeing it run matters.
