Fine and Rough Boring Heads are essential tools in CNC machining, specifically designed to meet different stages of the boring process. The rough boring head is used for removing larger amounts of material quickly, preparing the hole with high efficiency and stable cutting performance. Once roughing is complete, the fine boring head takes over, allowing precise adjustments to achieve micron-level accuracy in hole diameters and superior surface finish. Together, they form a complete boring solution that balances speed, accuracy, and repeatability, ensuring that both production efficiency and machining quality are maintained. Whether for small-batch high-precision parts or mass production of automotive components, these boring heads deliver reliable results across diverse applications.
The design of Fine and Rough Boring Heads highlights stability, adjustability, and durability.
Rough Boring Heads: Built with a strong and rigid structure, these heads allow large-diameter boring and high feed rates without sacrificing tool life. The optimized geometry ensures stable chip evacuation and minimal vibration during heavy cuts.
Fine Boring Heads: Equipped with ultra-precise adjustment mechanisms, these heads can achieve diameter accuracy within microns, while producing excellent surface finishes. Fine-tuning is possible with micrometer screws or digital readouts, making them suitable for the most demanding tolerance requirements.
Shared Features: Both types are manufactured from high-grade alloy steel with heat treatment for superior wear resistance and long service life. They are available in different modular configurations to suit HSK, BT, PSC, VDI, and BMT holders, ensuring wide compatibility with modern CNC machining centers.
By combining durability with precision engineering, Fine and Rough Boring Heads provide optimized cutting performance, reduced cycle times, and extended tooling lifespan.
Boring Diameter Range: Rough boring heads typically cover 20 mm to 250 mm; fine boring heads usually range from 2 mm to 200 mm, depending on the model.
Adjustment Accuracy: Fine boring heads can achieve precision adjustments in increments of 0.002 mm or finer.
Clamping System: Hydraulic or mechanical clamping options ensure secure tool holding.
Tool Interface: Available for HSK, BT, PSC, VDI, and BMT machine tool interfaces.
Balancing: High-speed balancing capability supports spindle speeds up to 12,000 RPM for fine boring and 6,000 RPM for rough boring.
These specifications provide flexibility, making the heads adaptable to both heavy-duty roughing and ultra-precise finishing.
Setup: Install the boring head securely in the machine spindle or tool holder. Ensure all mounting surfaces are clean and free from debris.
Tool Selection: Choose the rough boring head for initial hole enlargement and the fine boring head for final precision finishing.
Adjustment: For fine boring, use the micrometer adjustment screw or digital adjustment device to set the required diameter with high accuracy.
Cutting Parameters: Apply appropriate cutting speeds and feeds based on material type. Avoid exceeding recommended RPM to prevent chatter.
Maintenance: Regularly clean the head and check for wear on the insert pockets, screws, and adjustment mechanisms. Replace inserts as needed to maintain accuracy and surface finish.
Following these instructions helps ensure consistent machining results, reduced tool replacement costs, and extended holder lifespan.
Aerospace: For engine housings, landing gear components, and turbine parts that demand ultra-tight tolerances.
Automotive: For cylinder blocks, transmission housings, and other high-volume parts requiring efficient roughing followed by fine finishing.
Medical Equipment: For surgical tools, implants, and high-precision components where dimensional accuracy is critical.
Mold and Die Manufacturing: For boring mold cavities and die components that require smooth finishes and precise geometry.
