Product OverviewDesigned for precision deep-hole boring in heavy-duty components, the TK2140 machines bores up to ∅400 mm with a spindle output torque of 28 KN·m and an 80 KN feed carriage. It delivers consistent straightness and surface finish over long travel distances, making it suitable for hydraulic cylinders, gun barrels and large tubular parts.
Key Features- Max. boring diameter: ∅400 mm for large tubes and barrels.
- Spindle output torque: 28 KN·m for sustained cutting power.
- Feed force (feed carriage): 80 KN to support long-hole tool advancement.
- CNC programmable feed for improved accuracy and repeatability.
- Compatible with BTA tooling and deep-hole coolant/chip evacuation systems.
Recommended Configurations- BTA deep-hole tooling: precise internal boring with integrated chip removal.
- High-pressure coolant system: enhances chip evacuation and tool cooling.
- Steady rest support system: prevents workpiece deflection on long parts.
- Servo automatic feed control: increases feed precision.
- Chip conveyor: improves cleanliness and automation.
Application Case- Client: Oil & Gas Equipment Manufacturer – United States.
- Use Case: Deep-hole boring of thick-walled steel hydraulic cylinder tubes (∅390 mm × 4500 mm).
- Setup: TK2140 with BTA tooling system, high-pressure coolant pump, dual steady rest supports.
- Results: Boring straightness deviation: ≤ ±0.03 mm; surface roughness: ≤ 3.0 μm; cycle time per full-length part: 65 minutes; client feedback: "This machine gives us both torque and precision—perfect for our heavy-duty cylinder line."
