Speed vs. Precision: Why You No Longer Have to Make the Choice with Your CNC Machines

When the Matimop Eureka R&D network recognized this issue, they started looking into ways to boost efficiency without revamping their entire network of CNC machines. After researching coolant-driven spindle speed increasers, it became clear that they could rely on this solution to boost machining RPMs without sacrificing precision or accuracy.  In fact, they found that working at higher speeds could actually improve quality in many key cutting applications.  

The Problems with Standard Machining Approaches

Large-scale machining operations are often associated with expansive work spaces and powerful spindles. However, there are plenty of projects that require high performance cutting (HPC) work with filigree tools.  Whether it’s a micro-structuring application or you have to create small cavities, standard milling machinery can’t provide the necessary speeds to make these small diameter tools work optimally.    

Executing HPC processes on standard milling machinery at low speeds can impact cutting accuracy.  Even when working at maximum power, the result is often a poorly finished product which requires additional work to meet customer specification.  In the end, running HPC jobs on standard machines is not only inefficient, it is also an incredible waste of energy.

Researchers have discovered that augmenting the machining approach with a coolant-driven, high speed machine spindle effectively solves these issues for companies that need more precision in their cutting operations.

How Coolant-Driven Spindles Change the Game

For most companies, replacing all their CNC machines with new high speed models would cripple their business. This catch-22 has always put machine cutters in a tricky situation—but research shows that coolant-driven, high speed machine spindles can relieve the pressure. 

By adding HSM spindles to the tool magazine, companies can seamlessly move between conventional tasks and micro-cutting processes that require small diameter filigree tools – all on the same machine without operator intervention. There are multiple benefits to implementing these coolant-driven speed increasers:

  • Increased feed rate: By increasing your cutting speed, you can achieve faster machining production time. This is critical for increasing throughput and meeting those large purchase order demands.
  • Greater efficiency: You can reduce total amount of downtime because you’ll be operating at optimal speeds for HPC—extending tool life and reducing your number of tool changes.
  • Better quality: Coolant-driven spindles can run at 50,000 RPMs, which is ideal for small diameter tools. You’ll cut faster, produce high surface qualities and work with greater geometric accuracy.

 It’s Time to Streamline Your Machining Processes

Don’t let small cutting processes keep you from delivering a high quality product in a shorter amount of time. The Eureka researchers found that Colibri’s coolant-driven spindles can shorten machining time by up to 65% while increasing service life by up to 800%. Producing such high quality products so quickly is an asset to any machining business in any industry.  In the end, they found that investment in coolant-driven, high speed machine spindles is far more valuable than purchasing an entirely new set of CNC machines.
