Machine Coolant Nozzle

Name: Machine Coolant Nozzle | Adjustable Coolant Spray Nozzle - Frigate
Price: 249.00 USD
Availability: InStock

Tool repositioning in 4-axis or 5-axis CNC machines often causes the coolant stream to lose alignment with the cutting edge, leading to uneven cooling and tool wear. The Machine Coolant Nozzle is engineered with adjustable articulation and lock-in geometry to maintain directional accuracy under multi-axis movement. Its indexed orientation allows precise realignment without disassembly, ensuring consistent coolant impact across all angular tool positions. This reduces thermal cycling, especially in contouring and profiling applications.

Product Description

Deep hole drilling and slot milling frequently suffer from poor chip evacuation, resulting in chip re-cutting, tool jamming, and surface scoring. The Machine Coolant Nozzle uses converging-diverging flow channels and high-velocity jet profiles to create sufficient hydraulic force for chip flushing. The design ensures minimal backflow and maintains positive chip ejection in confined geometries. This leads to smoother surface finishes, extended tool life, and reduced cycle interruptions.

Surface Finish

Internal – Ra ≤0.8 µm (honed); External – Ra ≤1.6 µm (smooth finish)

Burr-Free Requirement

Internal Passages – ISO 13715 compliant; Edge Radius – ≤0.1 mm (laser deburred)

Corrosion Protection

Nickel Plating (5–10 µm), Anodized (Type II, 15–25 µm) and Passivation (per ASTM A967)

Flow Rate

@ 10 bar – 0.2–20 L/min (varies by orifice); CV Factor – 0.1–2.5 (adjustable via design)

Certification Standards

ISO 9001:2015, DIN 11851 (Threads), RoHS/REACH Compliant

Technical Advantages

Manually adjusting fixed coolant lines during tool changes or job setups contributes to non-productive time and misalignment errors. The Machine Coolant Nozzle is designed for tool-free repositioning through magnetic base mounts or quick-index collars, enabling rapid and repeatable adjustments. Operators can maintain precise coolant direction across different tools without interrupting production flow. This improves changeover efficiency and minimizes human error in complex batch operations.

High coolant consumption rates often overload the pump system and reduce filtration efficiency, especially in large production setups. The Machine Coolant Nozzle features internal flow-conditioning structures that regulate volumetric flow while maintaining required exit velocity. This reduces coolant waste and lowers pump energy demand without compromising thermal or chip evacuation performance. The controlled flow resistance improves system reliability in long-duration or unmanned machining.

Industry Applications

CNC Milling of Heat-Resistant Alloys

Delivers high-pressure coolant to prevent thermal softening and maintain edge retention in titanium, Inconel, and hardened steels.

Deep Hole Drilling in Automotive Blocks

Enhances chip evacuation and prevents tool seizure in long, narrow bores using high-velocity directed coolant streams.

Multi-Axis Aerospace Component Machining

Maintains consistent cooling across complex tool orientations to reduce asymmetric wear and improve tolerance control on contoured surfaces.

High-Speed Die and Mold Milling

Controls thermal expansion and flushing efficiency in fine cavity cutting during extended tool engagement in hardened tool steels.

Precision Medical Implant Machining

Ensures stable coolant delivery in micro-milling operations where even minor thermal deviation affects geometry and surface finish.

Gear Tooth Profile Grinding and Hobbing

Prevents localized overheating and abrasive loading by directing coolant precisely to active cutting flanks and chip removal zones.

Chemical and Thermal Durability in Aggressive Environments

Coolants with high pH, synthetic additives, or extreme temperatures often degrade standard nozzles, causing flow instability and dimensional drift. The Machine Coolant Nozzle uses chemically resistant polymers or stainless-steel alloys to withstand corrosive and thermal stress. Consistent geometry prevents clogging and deformation over extended use. Suitable for machining alloys like Inconel, titanium, and hardened steels.

Excessive heat at the cutting interface lowers tool hardness and compromises part accuracy. The Machine Coolant Nozzle directs high-pressure flow precisely at the shear zone for rapid heat removal. Reduced thermal distortion helps maintain tool edge integrity and micro-level dimensional control. Flow geometry ensures stable coolant film at high spindle speeds.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

How does Frigate ensure coolant jet stability under variable spindle speeds?

Frigate designs each Machine Coolant Nozzle with flow-conditioning channels that maintain jet coherence under varying RPMs. This prevents coolant deflection caused by centrifugal forces during high-speed rotation. Stable jet impact improves thermal removal and chip flushing. It also ensures coolant hits the tool exactly where needed regardless of spindle speed changes.

What makes Frigate’s nozzles suitable for abrasive and corrosive coolant environments?

Frigate uses chemically inert polymers and corrosion-resistant stainless alloys like 316L in nozzle construction. These materials withstand aggressive coolants with high alkalinity, chlorides, or synthetic additives. Long-term exposure does not affect dimensional stability or flow characteristics. This makes Frigate nozzles reliable in harsh shop conditions over extended cycles.

Can Frigate Machine Coolant Nozzles be integrated with automated tool changers?

Yes, Frigate nozzles are designed for quick-indexing and fixed alignment systems. They do not require manual repositioning after each tool change. This supports seamless integration in ATC-equipped machining centers. Coolant always hits the correct cutting point, reducing downtime and setup errors.

How do Frigate nozzles improve chip evacuation during high-feed face milling?

Frigate nozzles use high-velocity, narrow-angle jets to generate enough force for lifting and flushing chips from wide cut areas. Flow angle and speed are engineered to match chip trajectory during high material removal rates. This prevents re-cutting and chip welding issues. It also improves tool edge life and surface integrity.

What pressure range are Frigate nozzles optimized for in precision machining?

Frigate Machine Coolant Nozzles operate efficiently in the 20–100 bar range, depending on orifice design and internal flow paths. Flow is laminar and focused at lower pressures, while high-pressure applications maintain stream integrity without atomization. Each nozzle is tested for flow rate vs. pressure drop characteristics. This ensures coolant delivery matches exact thermal and flushing demands.
