How long do CNC spindles last?
A high-quality CNC spindle is typically rated to last between 2,000 and 5,000 operating hours. Longevity can be extended by following the proper machine warm up process to distribute bearing grease and ensuring the cooling system is fuctioning for every job.
What size of CNC spindle to use with a Onefinity CNC machine?
Onefinity machines support two primary spindle diameters: 65mm (typically for 800W or 1.5kW units) and 80mm (for more powerful 1.5kW or 2.2kW units).
The 80mm spindle is the most popular upgrade because it allows for larger ER20 collets, which can hold bits with up to 1/2"" shanks, providing significantly more versatility for heavy-duty woodworking.
How to choose a CNC spindle
To choose a CNC spindle, you should consider your power availability, cooling preference for and the types of materials you plan to cut.
How does a CNC spindle work
A CNC spindle works by using a Variable Frequency Drive (VFD) to convert standard household power into a precisely controlled three-phase electrical signal, allowing for software-controlled speed adjustments and constant torque.
What is CNC spindle?
A CNC spindle is a high-performance electric motor designed specifically for continuous industrial cutting, serving as the "heart" of the CNC machine that rotates the cutting tool.
