Applicable Industries & Workpieces

This tool is engineered for high-precision deep-hole machining in:

1. Hydraulics & Heavy Machinery: Hydraulic cylinder bores (2-12m length), gearbox housings.
2. Aerospace & Defense: Titanium alloy components, missile/weapon barrel bores (IT7 tolerance).
3. Energy Equipment  turbine rotor bores.
4. Automotive: Engine cylinder liners, transmission case deep bores.
5. Mold & Die: Cooling channels in large plastic injection molds (φ50-φ200 mm bores).

Product Features

1.  

Superior Stability & Vibration Control

1. • 1:1000 Tapered Shank Design: Minimizes cutting vibration even at extreme depth ratios.
   • Welded Carbide Guide Pads (2-4 pads): Ensures consistent bore straightness and roundness (0.05mm/1000mm straightness).
2.  

Efficient Chip Management

1. • Internal Coolant Delivery: Flushes chips directly from the cutting zone, avoiding clogging (critical for deep bores).
   • Optimized Chip Breaker: Breaks swarf into small segments, reducing re-cutting and tool wear.
2.  

Precision & Adjustability

1. • Micron-Level Adjustment Mechanism: Radial adjustment screw compensates for errors (±0.02mm), ensuring tight diameter tolerance (IT7).
   • Modular Assembly: Interchangeable components adapt to different bore sizes/depths, reducing tool inventory costs.
2.  

Durability & Cost-Effectiveness

1. • Ultra-Fine Grain Carbide + Coating: Extends tool life by 30% vs. standard carbide (resists wear in high-temperature machining).
   • Indexable Insert Design: Replaceable cutting edges eliminate full tool replacement, lowering operating costs.
2.  

High Load Capacity

1. • Adhesive-Bonded Tool Joint: Withstands 200N cutting force (14kg/cm² bonding strength), suitable for heavy-duty boring.

Packaging & Service

• Packaging: Sealed moisture-proof box + wooden crate (for large tools).
• Service: Free technical consultation (cutting parameter optimization), 12-month warranty, customizable tool design.
