The most common complaints from machine tool buyers are about accuracy that drops after installation, machines that differ from the quote, missing safety features, poor documents, slow spares and support, and rust or damage in transit. Most of these can be prevented before shipment.
Below are the common complaints, with the check that prevents each one.
The machine is not what was quoted
A different controller series, a lower-grade ball screw, a smaller motor or missing accessories are common surprises. Sometimes the maker changes a part because of supply problems and does not tell the buyer.
The fix is a written specification with makes and models for key parts, and an inspection that checks the nameplates and labels against it. Our guide to writing a CNC lathe specification shows what to list.
Accuracy problems
- The test chart showed good values, but the parts are out of tolerance. This often means the chart was copied, or the machine was not tested properly.
- The machine was accurate at the factory but not after installation. This is often a foundation or levelling problem, or damage in transit.
- Accuracy drifts as the machine warms up, which points to thermal growth that was never tested.
Safety and compliance gaps
Buyers in Europe and North America often find missing guards, interlocks that can be bypassed, or a panel that does not meet local electrical rules. Fixing these after arrival is slow and can stop the machine from being used legally. Agree the safety and electrical standard in the contract, and check them at the trial.
Under most rules, the importer or the employer carries legal duties for an unsafe machine. Confirm your obligations with your regulator before the machine arrives, not after an inspector finds the gap.
Support, spares and documents
- Spares take weeks to arrive because they are made to order or shipped without urgency.
- The maker is slow to respond once the machine is paid for, especially on faults with bought-in parts.
- Manuals are thin, in poor English or missing electrical drawings and parameter backups.
- Warranty claims stall over who pays freight, duties or engineer travel.
How to prevent them
Most of these problems come from vague contracts. Agree response times, spares lists, document lists and warranty costs before you order. See machine tool warranty for the wording to agree.
Damage and rust in transit
Rusted slideways and broken handles are common on arrival. They come from poor rust preventive, torn VCI wrap, weak crates or loose accessories. Supervised packing with photos prevents most of this and gives you evidence for an insurance claim if it still happens.
Many of these issues are covered in our founding article on why quality drops after the first container. The same pattern applies to machines.
