Deep Hole Honing Machines Selected by the Incoming Bore and Honing Allowance
Honing starts after the bore exists. Provide incoming geometry, allowance, material, bore type, depth, target tolerance, surface texture and inspection method before selecting the machine and tool strategy.
When to Review Deep Hole Honing
Deep hole honing is considered when a pre-machined bore requires controlled sizing, geometry correction or surface finishing.
Good starting fit
- An existing cylindrical bore
- Measured incoming geometry and allowance
- Defined diameter, geometry or surface requirements
- Workpieces that can be supported and flushed through the honing zone
Review preparation or another process when
- The hole has not yet been created
- Large or highly variable stock remains
- Severe bend or position error requires earlier correction
- Blind, stepped or interrupted geometry needs special tooling
- Incoming bore data is unavailable
Inputs That Define the Honing System
Process and machine boundary
- Roundness, cylindricity, straightness, taper and position
- Roughness, crosshatch or texture requirement
- Stone, expansion, stroke, rotation, coolant and filtration
- Weight, support, loading, quantity and takt
Reference Configurations for Initial Selection
| Reference configuration | Honing range | Reference depth | Current website reference |
|---|---|---|---|
| 2MK50 × 3 m | Ø30–500 mm | Up to 3,000 mm | IT8–IT10 and Ra 0.2 μm are page references. |
| 2MK50 × 6 m | Ø160–500 mm | Up to 6,000 mm | IT7–IT8 and Ra 0.2–0.4 μm are page references. |
The starting bore ranges differ. Machine length alone does not select the configuration. Final values depend on incoming geometry, allowance, material, tool, coolant, stroke and inspection method.
From Incoming Bore Data to a Honing Proposal
1. Measure the bore
Size, taper, roundness, cylindricity, straightness and surface.
2. Confirm allowance
Nominal stock and variation over depth.
3. Select the strategy
Tool, stone, expansion, stroke, rotation, coolant and filtration.
4. Define acceptance
Locations, instruments, texture, sample and limits.

ORDER CONFIGURATION — NOT DELIVERY OR ACCEPTANCE
Two anonymized 2025 records show different tooling and site requirements for Mexico and Hungary. They verify ordered configurations only; they do not prove production, shipment, installation, bore accuracy or acceptance.

How much allowance is needed for honing?
It depends on incoming error, material, bore size, depth, tool and target. Provide measurements along the bore, not one nominal diameter.
Can honing correct straightness?
Honing can influence geometry within a process-specific boundary, but does not automatically correct all position or severe bend errors.
Can the machine hone blind or stepped bores?
These geometries require tool, overrun and abrasive-flow review. Show the full section in the drawing.
Do the order records prove customer acceptance?
No. Separate inspection, logistics, installation and signed acceptance evidence is required.
