Transforming Standard Equipment into a High Speed CNC Machine

In short, high speed spindles allow you to boost current CNC machine RPM – when needed.  Where standard machines typically operated around 10,000 to 15,000 RPMs, a high speed spindle allows you to perform the same task between 20,000 to 60,000 RPMs. They are ideal for use in applications that require small tools such as:

  •        Milling
  •        Drilling
  •        Grinding
  •        Engraving
  •        Chamfering
  •        Threading

The benefits of using high speed machining processes are hard to ignore.  If you can machine faster, you can increase output and profitability across all applications.  When a high speed spindle was used for thread milling on a SAE 4340 work piece, per part machining time was cut by 70%.  In a different application – milling a mold of D2 material – high speed spindles cut overall machining cycle times by over 60% and the polishing process time was cut in half. 

While your results will vary from application to application, machine time will decrease dramatically.

Rapid Transformation

To change standard equipment into a high speed CNC machine, try to limit modification work from the start.  For example, we designed our high speed machine spindle to be plug and play.   Simply attach the Colibri high speed spindle to your existing spindle and your work is done – it will utilizes the machine coolant system to reach higher RPMs.  Other solutions require companies to install an external sophisticated air supply system or draw additional power from the machine to increase speed.

To avoid workflow disruption, choose a compact solution that can utilize the machine’s ATC and can be stored in the tool magazine of the machine.  Many of the old style speed increasers are too clunky to fit within these systems.

Modifying existing equipment to yield productivity comparable to high speed machining allows you to increase output without have to acquire additional machinery.    Although ROI will vary from company to company, the efficiency benefits of high speed machining will quickly improve your bottom line.
