Cylinder Bore Turning and Milling Composite Center

-- Steady & Reliable Manufacturer --

Specialized Engineering for Deep-Hole Internal Geometry

The Cylinder Bore Turning and Milling Composite Center is a niche powerhouse tailored for the hydraulic and engine industries. Machining internal bores is notoriously difficult due to vibration, poor chip evacuation, and heat buildup. Our center solves these issues with a reinforced Z-axis travel and an integrated, high-pressure through-spindle coolant system (up to 70 bar). It combines deep-hole boring with internal milling and threading, ensuring that all internal ports are perfectly aligned with the bore. By eliminating the move from a boring mill to a separate machining center, you guarantee the concentricity required for high-pressure fluid power integrity.

Specification

Critical Spec	Measurement
Bore Diameter Range	Φ20mm - Φ500mm
Boring Depth	Up to 2500mm (Optional 4000mm)
Internal Finish	Ra 0.4 (Honing Quality)
Boring Accuracy	H7 - H8 Tolerance

Cylinder-Specific Industry Use

Hydraulics: Multi-stage telescopic cylinder barrels and piston rods.
Marine Engines: Precision cylinder liners for large-scale diesel engines.
Mining: Heavy-duty hydraulic leg supports for longwall mining systems.

Key Engineering Advantages

Anti-Vibration Tech: Specialized damping systems within the boring bar holders prevent chatter during deep passes.
Integrated Porting: Mill internal snap-ring grooves and ports in the same setup as the bore.
Mirror-Like Finish: Capable of achieving Ra 0.4, often eliminating the need for secondary honing.

Logistics & Service

Standard export packaging for long-bed machines. Shipping via flat-rack container or bulk vessel. 30% deposit with 70% balance paid after Factory Acceptance Test (FAT).

FAQ

Q: Can it handle hardened liners?A: Yes, our high-torque gear-head spindles are designed specifically for boring hardened materials up to HRC 55.
Q: How do you handle chip evacuation in deep bores?A: We use high-pressure (70 bar) through-tool coolant to force chips out of the bore efficiently.
Q: Is a steady rest included?A: For long cylinders, we provide programmable hydraulic steady rests to prevent deflection and ensure straightness.
