Welcome to the Colibri HSM Spindles Blog.  It’s a dynamic information resource updated weekly that offers you a world of information about CNC machining processes and high-speed machining news in particular – from the basic to the complex . And, we want to know what you think, so feel free to comment on any of our posts, whether it be on CNC manufacturing issues, new technology in the industry, white papers and info-graphics, or Colibri company news.

Jet Spindle Application Insights: Engraving

Engraving is an ideal application for jet spindles and process time savings of 6-12X can be achieved, which is the equivalent of saving 80-98% saving in machining time!

NEW JET Spindle Operating Parameters

We have updated our Jet Spindle Operating Parameters tables to provide more information. We now include information connecting high-pressure coolant pressure and flow to unit torque. We provide a list of cutting tools and sizes for different material grade categories. We relate to collect size and type, runout, and warranty.

BIG Opportunities – SMALL Tools

Operationally, once the roughing processes are completed on large machines, we need to physically move the rough part to machines that are better equipped to complete the finishing processes efficiently and accurately. This implies a string of additional activities and costs, including additional costly high-speed machines, planning, and machine setup. Ideally, we want to complete all the processing efficiently and accurately on the same large machine and in the same setup. This is much more profitable.


As a reference, when looking at cost of processing a part, machining cycle time is usually 40% of the budget, while the cost of tools (including the costs of Jet Spindles) is usually around 3% of the budget. So, with this in mind, we are primarily concerned with improving cycle times and this article looks at the BIG impact of Material Removal Rates with SMALL Tools, i.e. shorter cycle times with SMALL Tools.  Let’s proceed

BIG Savings – SMALL Tools

Colibri Spindles specializes and is the world leader in coolant powered JET Spindle Speeders for the metal machining industries. The BIG Savings with small tools comes in Cutting Cycle Times by 40%!
