| Machine Configuration | Processing functions | Side drilling, end drilling, slotting, grooving, and optional routing or milling functions according to the machine design | Multifunctional processing can reduce workpiece repositioning, labor input, and cumulative positioning errors. | Review the machine layout, tool list, processing samples, and detailed functional specifications. | High |
| Working Capacity | Workpiece size compatibility | Must be selected according to the buyer’s panel length, width, thickness, hole position, and clamping requirements | A machine may perform well but remain unsuitable if the working envelope does not cover the buyer’s actual panel range. | Compare the supplier’s working range with at least three representative production drawings. | High |
| Drilling Performance | Spindle speed and drilling capacity | Configuration-dependent; high-speed drilling units are commonly used for repeated panel and furniture-hole operations | Spindle speed, tool diameter, material type, and feed rate jointly affect hole quality, cycle time, and tool life. | Request test results using the same board material, tool type, hole diameter, and production conditions. | High |
| Positioning Accuracy | Repeatability and dimensional consistency | Should be stated in the technical specification with a defined measurement method and test condition | Consistent positioning is essential for dowel holes, connector holes, cabinet components, and parts requiring assembly alignment. | Ask for a documented accuracy test, sample measurements, and tolerance records rather than relying only on general claims. | High |
| Mechanical Structure | Frame rigidity and vibration control | Heavy welded or machined structures generally provide better stability than lightweight structures under continuous production loads | Rigidity influences surface quality, hole accuracy, noise level, and long-term mechanical stability. | Inspect frame construction, guideway support, spindle mounting, machine weight, and vibration-control design. | High |
| Drive and Motion System | Guideways, ball screws, racks, and servo or stepper drives | Component selection should match axis load, acceleration, duty cycle, and required positioning performance | Motion-system quality affects accuracy, service life, maintenance frequency, and production reliability. | Confirm component specifications, protection arrangements, lubrication points, and replacement availability. | High |
| Control System | Programming and operation interface | Should support parameter setting, job storage, error alarms, manual operation, and clear operator guidance | An intuitive control system reduces training time and helps operators identify faults quickly. | Request a live software demonstration covering program creation, parameter changes, alarm history, and data backup. | Medium |
| Automation Compatibility | Barcode, CAD/CAM, networking, and production-line integration | Availability depends on the control system and machine configuration; interfaces should be clearly documented | Integration can improve data accuracy, reduce manual input, and support higher-volume manufacturing. | Confirm file formats, communication protocols, barcode requirements, and compatibility with existing production software. | Medium |
| Tool Management | Tool changing and tool-life control | Manual or automatic tool changing may be available; tool capacity should reflect the planned product range | Suitable tool management reduces setup time and helps maintain consistent cutting performance. | Check tool-holder standards, tool-change time, tool-life monitoring, spare-tool requirements, and sharpening recommendations. | Medium |
| Manufacturing Quality | Assembly, wiring, and quality-control process | Important controls include incoming inspection, assembly inspection, electrical testing, calibration, and final trial operation | A documented quality process reduces the risk of hidden assembly defects and inconsistent machine performance. | Request inspection records, electrical test reports, calibration documents, and a factory acceptance test procedure. | High |
| Electrical Safety | Protection and compliance documentation | Should include emergency stops, protective covers, grounding, overload protection, and applicable market compliance documents | Safety features protect operators and may be required for installation, insurance, or import approval. | Verify the electrical schematic, safety-circuit design, conformity documents, and local installation requirements. | High |
| Dust and Chip Management | Extraction ports and dust-control performance | Extraction design should match the number of cutting units, air volume requirements, hose diameter, and workshop layout | Effective dust removal improves visibility, machine cleanliness, tool life, and workplace safety. | Check recommended airflow, extraction-port dimensions, filtration requirements, and test performance with the intended material. | Medium |
| Service Support | Installation, commissioning, and operator training | Support may include remote guidance, manuals, installation instructions, commissioning assistance, and operator training | Good onboarding shortens the time from delivery to stable production and reduces avoidable operating errors. | Obtain a written support scope, training schedule, language options, and responsibilities for installation preparation. | High |
| After-Sales Response | Technical response and spare-parts availability | Response time, remote diagnostic capability, spare-parts stock, and replacement lead time should be contractually defined | Downtime costs can exceed the original price difference between competing machines. | Ask for service channels, escalation procedures, critical spare-parts lists, and typical response commitments. | High |
| Delivery and Acceptance | Lead time, packaging, and factory acceptance testing | Delivery depends on configuration, production schedule, inspection requirements, and shipping method | Clear acceptance criteria help prevent disputes regarding performance, accessories, and delivery condition. | Define packing standards, shipment documents, acceptance samples, performance tolerances, and payment milestones. | High |
| Operating Cost | Power, consumables, maintenance, and labor | Total cost includes electricity, drills and cutters, lubrication, dust extraction, maintenance, and operator time | The lowest purchase price does not always provide the lowest cost per finished part. | Calculate cost per workpiece using expected production volume, tool consumption, labor rates, and planned service intervals. | High |
| Buyer Fit | Production volume and product variety | Choose configuration based on batch size, daily operating hours, material mix, changeover frequency, and future expansion plans | Over-specification increases investment, while under-specification can create bottlenecks and early replacement costs. | Prepare a requirement sheet covering current output, peak demand, product sizes, materials, and expected growth. | High |
| Supplier Assessment | Factory capability and reference validation | Relevant evidence includes production facilities, test equipment, technical staff, export experience, and application references | Verifiable manufacturing capability is more reliable than catalog descriptions or unconfirmed performance statements. | Conduct a factory audit or video inspection and request references using similar materials and production requirements. | High |
