TZK06-70 CNC Deep-Hole Drilling and Boring Machine: Project Agreement Record

This anonymized page summarizes the configuration and acceptance criteria recorded in a 2024 project agreement for one TZK06-70 CNC deep-hole drilling and boring machine. The figures below are agreement terms, not measured results or proof of final acceptance.

Configuration recorded in the agreement

• Machine model: TZK06-70 CNC deep-hole drilling and boring machine.
• Maximum drilling/boring depth: 1,000 mm.
• Maximum chucking diameter: Ø250 mm.
• Chuck through-bore diameter: Ø138 mm.

Agreement acceptance criteria

Hole-diameter accuracy IT9–IT10 and exit deviation no greater than 0.4 mm per 1,000 mm are stated as project acceptance criteria. The available materials do not contain a machining-process record, measured results, or a final acceptance report. These criteria must not be presented as verified performance.

Photo and evidence limits

No project-specific public photograph is available for this case, so no unrelated machine image is used.

For a comparable workpiece

For an engineering review, provide a sanitized drawing and specify the material, starting-bore condition, target bore diameter and depth, dimensional tolerances, surface-finish requirement, concentricity or straightness, batch size, and inspection method. The process and machine configuration can then be reviewed against the actual requirements.
