Drilling, boring and optional finishing routes
Review the solid or existing bore, finished diameter, depth, stock allowance, rotation, support arrangement and inspection requirements before selecting a machine family.
This family is considered for long workpieces that require drilling, enlargement, boring or a combined route. The starting bore and material to remove are as important as the finished size.
| Reference configuration | Drilling diameter | Maximum boring diameter | Reference depth |
|---|---|---|---|
| TK2120 × 2 m | Ø30–80 mm | Ø200 mm | 2,000 mm |
| TK2120A × 2 m | Ø30–100 mm | Ø200 mm | 2,000 mm |
These are current reference values, not a universal capability envelope. Geometry, surface, accuracy and cycle results depend on starting bore, material, allowance, tool, coolant, support and inspection length.
Review drilling method, guidance and chip evacuation.
Review allowance, incoming geometry and boring tool access.
Decide whether rolling, SRB or honing belongs in the same or a following process.
Define rotation, supports, center height, loading and safety boundaries.
Identify the sample workpiece, starting condition, tool, allowance, measurement length, datum, instrument, temperature condition and permissible results. Values without those conditions remain references, not guarantees.
Prepare an Acceptance ChecklistDrilling creates or opens a hole. Boring enlarges or corrects an existing bore. A project may use one or both operations.
A combined route may be reviewed when material, allowance, wall condition and target surface are compatible. It is not assumed for every workpiece.
Allowance and incoming geometry affect tool selection, supports, passes and achievable results.
No. They become contractual only in signed project documents with the workpiece and inspection conditions.
Engineering review
Send the starting bore, finished diameter, depth, allowance, support data, quality requirements, production target and drawing.
