| 1 | Product Fit and Machine Configuration | The machine should match the workpiece material, dimensions, tolerances, production volume, and required operations such as face milling, slotting, drilling, or contouring. | A completed technical questionnaire, machine layout, working envelope, spindle specification, axis travel, table load, and sample-part review. | 15% | 1–5 |
| 2 | Accuracy and Repeatability | Published positioning accuracy and repeatability should be supported by recognized test methods, acceptance criteria, and inspection records. | Factory acceptance test results, calibration records, laser-interferometer reports where applicable, and dimensional inspection results for test parts. | 15% | 1–5 |
| 3 | Spindle and Cutting Performance | Assess spindle speed range, motor power, torque curve, taper type, runout, tool-holding method, and performance under the intended cutting conditions. | Spindle test data, runout measurement, continuous-load test, cutting demonstration, tool-change specification, and recommended cutting parameters. | 12% | 1–5 |
| 4 | Structural Rigidity and Thermal Stability | A rigid casting or fabricated structure, suitable guideways, effective vibration control, and thermal compensation help maintain machining consistency. | Machine mass, structural drawings or specifications, vibration test results, warm-up procedure, thermal drift data, and long-cycle machining samples. | 10% | 1–5 |
| 5 | Control System and Automation | The control system should support the required programming method, tool management, probing, data transfer, alarms, and operator safety functions. | Control-system specification, sample programs, interface details, option list, remote-diagnostics capability, and operator training plan. | 10% | 1–5 |
| 6 | Quality Management and Traceability | A documented quality system should control incoming materials, in-process inspection, final assembly, calibration, nonconformities, and corrective actions. | Quality certificates, process-control records, inspection plans, serial-number traceability, calibration certificates, and corrective-action examples. | 12% | 1–5 |
| 7 | Compliance and Machine Safety | The machine should satisfy applicable requirements for guarding, emergency stops, electrical safety, noise, documentation, and destination-market compliance. | Risk assessment, electrical diagrams, safety test records, declaration documents, user manual, conformity certificates, and inspection of guards and interlocks. | 10% | 1–5 |
| 8 | Service, Spare Parts, and Training | Evaluate installation support, response times, spare-parts availability, preventive-maintenance guidance, troubleshooting, and operator training. | Service-level agreement, spare-parts list, recommended inventory, support channels, training schedule, installation scope, and warranty terms. | 10% | 1–5 |
| 9 | Total Cost of Ownership | Compare purchase price together with tooling, installation, freight, utilities, maintenance, consumables, downtime risk, and expected service life. | Detailed quotation, energy requirements, maintenance schedule, consumables list, warranty coverage, lifecycle-cost estimate, and payment terms. | 6% | 1–5 |
