slant bed machine through-tool coolant

1. Power Turret

   • Refers to a motor-driven tool turret (e.g., servo-driven) capable of mounting rotating tools (such as milling cutters, drills), enabling milling, drilling, tapping, and other complex operations during turning.

   • Key distinction from conventional turrets: Tools can actively rotate, expanding the lathe's machining capabilities.

2. Through-Tool Coolant (TTC)

   • Coolant (cutting fluid) is delivered through the central channel of the tool directly to the cutting zone, enabling high-pressure cooling and chip evacuation.

   • Core advantages: Coolant acts precisely on the tooltip, reducing heat, minimizing tool wear, and flushing away chips to avoid clogging (especially in deep-hole machining).

Functional Features

1. High-Pressure Cooling System

   • Coolant pressure typically ranges from 20–100 bar (or higher), penetrating deep holes or complex cavities to enhance machining efficiency.

   • Ideal for titanium alloys, stainless steel, and other hard-to-machine materials, or high-heat, high-precision operations like deep-hole drilling and thread machining.

2. Multi-Channel Control

   • Each tool station on the power turret can independently control coolant activation and flow rate, achieving on-demand cooling.

   • Example: Activate through-tool coolant during milling and switch to external spray during turning.

3. Tool Compatibility

   • Requires internal-coolant tools (e.g., drills or end mills with central coolant holes) and sealed toolholders to prevent leakage.

Application Scenarios

1. Deep-Hole Drilling

   • For holes with depth-to-diameter ratios exceeding 5:1, through-tool coolant ensures effective chip removal, preventing tool breakage.

2. High-Speed Machining

   • Suppresses heat generation, reduces thermal deformation, and improves surface finish.

3. Composite Material Machining

   • Prevents burrs or delamination in fiber-reinforced materials via coolant flushing.

Key Considerations

1. Tool-Machine Compatibility

   • Ensure tool coolant channels match the machine’s pressure and flow specifications to avoid insufficient pressure or leaks.

2. Filtration and Maintenance

   • High-pressure coolant systems require precision filtration (e.g., ≤10μm) to prevent clogging of tool channels.

3. Sealing Integrity

   • Regularly inspect seals between toolholders and tools to prevent coolant leakage.

Standard Terminology Cross-Reference

• Chinese: 动力刀塔中心出水

• English: Through-Tool Coolant (TTC) / High-Pressure Coolant (HPC)

• Industry Terms: Central internal cooling, high-pressure through-tool coolant

• Colloquial Usage: "Tool-center coolant" or "turret-center coolant delivery"

Summary:
"Power Turret with Through-Tool Coolant" is a core feature of CNC machines for high-efficiency复合加工, leveraging high-pressure internal cooling to address challenges in deep-hole and difficult-to-machine material applications. It is widely used in aerospace, mold manufacturing, and precision engineering. Key considerations include coolant pressure, tool compatibility, and system maintenanc
