Component Specifications

Definition
Coolant passages are precision-engineered internal channels integrated into turret bodies of CNC lathes and turning centers. These passages facilitate controlled coolant flow to cutting tools and workpieces, managing heat generation during high-speed machining, reducing thermal expansion, improving tool life, and ensuring dimensional accuracy. They are typically part of a closed-loop cooling system that includes pumps, filters, and temperature control units.
Working Principle
Coolant is pumped through these passages under pressure, absorbing heat from cutting zones and carrying it away. The design ensures uniform distribution to multiple tool stations, maintaining consistent temperatures across the turret body to prevent thermal distortion and maintain machining precision.
Materials
Typically made from ductile iron, cast steel, or high-strength aluminum alloys with corrosion-resistant coatings. Internal surfaces may be treated or lined with materials like PTFE or ceramic composites to prevent erosion and chemical degradation from coolants.
Technical Parameters
  • Flow Rate 5-50 L/min
  • Diameter Range 3-20 mm
  • Surface Finish Ra ≤ 1.6 μm
  • Pressure Rating Up to 10 bar
  • Temperature Range 5-40°C
Standards
ISO 10791-7, DIN 8606
