For round tensile specimen preparation, preventive maintenance is mainly about keeping chips and coolant under control, protecting the spindle and slides, and catching toolholding or alignment issues before they affect specimen geometry. Exact intervals depend on your workload, materials, coolant use, and shop cleanliness, but most labs follow a simple time-based routine and adjust based on results.

A practical starting schedule is:

• Each shift or daily: remove chips, wipe down exposed surfaces, verify coolant level and flow, drain water from the air supply line, quick check of chuck and tailstock clamping.
• Weekly: clean around guards and sensors, inspect tools and holders for wear or damage, check hoses and fittings for leaks.
• Monthly or quarterly: clean the coolant tank and screens, check fasteners and covers, review backlash or unusual noise, confirm repeat setups are still holding your typical tolerances.
• Annually: a deeper mechanical and electrical inspection, plus a full service visit if you run high volume.

If you use standard libraries for ASTM, ISO, or DIN specimens, also include a periodic “dimensional sanity check” using your preferred measurement method so deviations are caught early.
