Drill Turning Tool Holders are precision-engineered solutions designed for high-efficiency drilling, boring, and deep-hole machining in lathes, CNC turning centers, and multi-tasking machines. Crafted from premium alloy steel or carbide and enhanced with advanced heat treatment, these tool holders deliver exceptional rigidity, wear resistance, and vibration damping under heavy cutting loads and high-speed operations, ensuring superior machining accuracy and extended tool life.
주요 기능:
1. Ultra-Durable Construction
– Manufactured from high-toughness alloy steel (e.g., 40Cr, 42CrMo) or ultra-hard carbide (tungsten steel), subjected to vacuum quenching and cryogenic treatment for hardness up to HRC 50-65 and 30% higher bending strength to withstand cutting shocks.
– Optional TiAlN/DLC coatings reduce friction, resist heat up to 800°C, and triple service life.
2. Precision Engineering
– CNC-ground surfaces guarantee minimal tool holder runout (≤0.005mm) and cutting head positioning accuracy (±0.01mm), achieving hole concentricity and surface finish up to Ra ≤1.6μm.
– Integrated internal coolant channels (optional) direct high-pressure coolant to the cutting edge, reducing heat and chip clogging, boosting deep-hole productivity by 40%.
3. Modular Versatility
– Compatible with ISO, DIN, CAT, and BT turret standards, supporting drill diameters from Φ3mm to Φ50mm (straight shank or Morse taper) for rapid tool changes and minimized downtime.
– Anti-slip grooves and dual-lock nut mechanisms enhance clamping torque by 50%, eliminating drill slippage during heavy-duty operations.
4. Application-Optimized Designs
– Heavy-Duty Type: Reinforced shank + helical chip flutes for continuous machining of stainless steel, titanium alloys, and hardened materials.
– Deep-Hole Type: Segmented damping structure + guide pads ensure straightness in holes up to 20× diameter depth.
– Multi-Function Type: Interchangeable heads for combined drilling, reaming, and chamfering operations.
Typical Applications:
– Automotive: High-volume drilling of engine block oil passages, wheel hub bolt holes.
– Aerospace: Deep-hole drilling in titanium alloy frames, composite stack machining.
– Energy Sector: Nuclear valve deep bores, wind turbine shaft long-hole drilling.
– Mold Making: Precision cooling channel drilling in mold cores (H7 tolerance).
Usage Guidelines:
– Installation: Tighten with a torque wrench (e.g., 120-150N·m for CAT40 shank).
– Cutting Parameters: Carbide holders recommend 80-150m/min cutting speed, 0.1-0.3mm/rev feed (material-dependent).
– Maintenance: Clean coolant channels regularly; apply rust preventive oil for storage.
