The Advantages of Through-Spindle Coolant

Posted by Dror Pockard on Jan 6, 2016 10:15:45 AM

High speed steel (HSS) tools and flood coolant have traditionally combined for reliable and cost-effective machining processes. However, when a machining giant like Haas Automation, Inc., starts to transition from HSS and flood coolant to carbide tools and through-spindle coolant, the manufacturing world takes notice. In a recent video, two representatives from Haas Automation demonstrated the advantages of through-spindle coolant over flood coolant.

Key Takeaways from the Haas Automation Video Demonstration

Coolant is necessary in all machining processes, but you may not realize how much of a difference the delivery method can make. These are the key advantages that Haas discovered when comparing traditional HSS and flood coolant machining to carbide and through-spindle coolant machining:

  • Faster Cutting: HSS and flood coolant require a peck drilling technique where the tool must continuously retract to allow chips to break and coolant to filter through the hole. Through-spindle coolant enables a “one-shot” cutting technique, clearing chips away with ease and speeding up the cutting process dramatically. 
  • Better Hole Quality: Holes made with HSS and flood coolant show noticeable tool marks, leaving a sub-par finish. In addition, the combination causes a bell-mouth effect, which can cause quality problems down the production line. The through-coolant spindle process supports much higher cutting speeds, meaning a higher quality carbide tool can be used for better overall hole quality.
  • Greater Throughput: In the video, the drilling test took the HSS and flood coolant setup about 50 seconds to complete, whereas the through-spindle coolant carbide tool finished in just under 20 seconds. Through-spindle coolant allows you to cut more holes in the same amount of time, improving throughput and enabling busy machine shops to meet high demands.
