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: Nuclear reactor pressure vessel guide tubes, 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).
1、Superior Stability & Vibration Control
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
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.
3、Precision & Adjustability
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.
4、Durability & Cost-Effectiveness
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.
5、High Load Capacity
Adhesive-Bonded Tool Joint: Withstands 200N cutting force (14kg/cm² bonding strength), suitable for heavy-duty boring.
6、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.

This machine tool is a special-purpose machine tool for machining cylindrical deep-hole parts. It is suitable for boring cylindrical deep-hole workpieces. During boring, an oil feeder is used to supply oil, and the chips are discharged to the chip hopper at the head of the machine through the cutting zone. During drilling, an internal chip removal method (BTA) is used, that is, an oil feeder supplies oil, and the chips are discharged from the inside of the drill rod to the chip hopper at the rear of the machine through the cutting zone.
Carbide Ball Teeth, also known as carbide ball inserts, tungsten carbide ball teeth, or conical picks, are a specific type of wear part and cutting tool characterized by their hemispherical (ball-shaped) head made of tungsten carbide. They are primarily designed for robust impact, crushing, and grinding applications, rather than precise shearing or slicing. Their unique design allows them to transmit high point load forces into the material, making them ideal for breaking extremely hard and abrasive substances.
