  • What is the difference between Air-Cooled and Water-Cooled Spindles?
    An air-cooled spindle uses a fan to circulate air and cool the motor, while a water-cooled spindle uses circulating water to dissipate heat. Water cooling generally offers superior efficiency, allowing for longer continuous operation at higher power levels, but requires additional plumbing and setup compared to air-cooled spindles. A typical difference in noise level between water-cooled and air-cooled CNC spindles is around 5-10 decibels (dB). Air-cooled spindles require less maintenance since there's no coolant system, but they still need to be vacuumed to remove fine dust. Important: DO NOT use high-pressure air to blow them out. The fan can act as a turbo, exceeding the RPM of the spindle and potentially damaging the bearings. For more information, YouTube has some great videos— just be cautious and avoid trying these things at home
  • Can I place the VFD on the Table without a Table mount stand?
    No, placing the VFD on a table without the stand could potentially damage the VFD due to restricted air flow. Air gets circulated from bottom to top.
  • What is included in a Spindle Kit?

  • What are the benefits of a Spindle Kit over a trim router?
    A spindle kit generally offers advantages over a trim router in terms of increased power, higher speeds, greater torque, and improved accuracy, making it better suited for heavier cutting tasks, longer continuous operation, and more demanding materials, particularly when used in a CNC machine setting; while a trim router excels in smaller, detailed, and precise trimming applications due to its compact size and maneuverability. Key benefits of a spindle kit over a trim router: Higher power and torque: Spindles are designed for heavier cuts and can handle more demanding materials like metals or dense hardwoods, whereas trim routers are better for lighter tasks like edge trimming. Greater speed range: Spindles often have a wider speed range, allowing for fine control over cutting speeds depending on the material and desired finish. Improved accuracy: Due to their design, spindles can provide higher precision and less runout, leading to cleaner, more consistent cuts. Longer duty cycles: Spindles are typically built for extended continuous operation, while trim routers may overheat if used for long periods on heavy tasks. CNC compatibility: Spindles are often specifically designed to be integrated into CNC machines, allowing for complex automated cutting patterns.
  • What currency is our pricing in?
    All pricing is in USD.
  • How Loud is a Spindle compared to a trim router?
    The Makita RT0701CX has a noise level between 80-100 decibels (dB). For reference, a normal conversation is between 60-70db, and a motorcycle is 100db. A spindle is generally significantly quieter than a trim router; most users report that a spindle produces a much more subtle hum, while a trim router can be quite loud and noisy, especially at high speeds, making a spindle the preferred option for quieter CNC operations. The bit cutting into the material will be significantly louder than the spindle itself.
  • What is the difference between 65mm and 80mm Spindle?
    The primary difference between a 65mm (ER-11 Collet) spindle and an 80mm (ER-20 Collet) spindle is their diameter. The 80mm spindle is larger, allowing for the use of larger cutting tools with thicker shanks compared to the 65mm spindle. Generally, a larger spindle diameter means greater cooling capacity. Additionally, you can get 80mm spindles in both 1.5 kW (110V) and 2.2 kW (220V) configurations. Additionally 65mm can use up to 1/4" shank and 80mm can you use up to 1/2" shank
  • Do you have a trade-in program to upgrade Spindle Kits?
    We currently are not offering any trade in programs at this time.
  • How many outlets do I need for a Spindle Kit and CNC?
    Recommended Setup: Two outlets on separate breakers: One outlet on its own breaker for the VFD and spindle kit. One outlet on its own breaker for the CNC.
  • Can the Spindle Kit be stored in a cold or hot environment?
    Air-cooled spindles offer certain advantages. Although they can be noisier when cold, you won’t have to worry about the coolant freezing, unlike with water-cooled spindles. Water-cooled systems can be more complex in this regard. If spindles are stored for a prolonged period, performing a break-in routine is beneficial. This routine helps distribute lubrication evenly, especially if the spindles were stored horizontally.
  • Does the VFD have vector control?
    Yes, it's called "Sensorless Vector Control" which is very common for VFDs.
  • Should I get a Braking Motor for my Spindle?
    For Onefinity machines we recommend a Motor Brake on all Elite Machines. No brake currently exists for open-loop stepper motors.
  • How long can I expect my spindle to last?
    Spindles are expected to last for many years. Signs of failure would be sandy-sounding bearings or high-pitched whine that doesn’t go away after the spindle has warmed up. This means your spindle requires maintenance and possible bearings replacement.
  • What CNC Machines are these Spindle Kits compatible with?
    Onefinity Elite Series machines Onefinity Pro Series machines Generic PWM controlled machines (Coming Soon) Generic RJ-485 controlled machines (Coming Soon) Shapeoko Pro Series machines (Coming Soon)
  • How long can a spindle run for?
    The run time of a spindle can vary depending on factors like the material being machined, the spindle speed, and the cooling method used. Generally, these spindles can run continuously for several hours if properly cooled and maintained.
  • Can a Spindle Kit be used to cut metal?
    Yes, with the right feeds and speeds and the right cutting bits, a CNC spindle kit can be used to cut non-ferrous metals.
  • Can I plug my Spindle kit into a GFI?
    VFDs do not work with GFI (Ground Fault Interrupter) outlets. This is because the VFD converts AC from the wall to DC and then back to AC at a different frequency (not 50/60 Hz). This conversion process causes an imbalance in the AC current, which will trip a GFI outlet.
  • Will VFD Mounting Options be available if I want to change my mounting option after I purchase a VFD? (Wall Bracket/ Table Top Base/ QCW Hanger)?
    Yes, visit Onefinity CNC @ Onefinitycnc.com to purchase additional mounting options.

  • What are the sound levels (in decibels) of the air-cooled and water-cooled spindle?
    Air-cooled spindles: The noise level of a 1.5 kW air-cooled spindle typically ranges around ~60-70 decibels (dB). Water-cooled spindles: A 2.2 kW water-cooled spindle typically operates at around ~60-70 decibels (dB), similar to the 1.5 kW versions. A typical difference in decibel level between a water-cooled and air-cooled CNC spindle is around ~5-10 dB. Keep in mind that other factors, such as the material being cut and the cutting speed, can also influence the overall noise level of your CNC setup. The bit cutting into the material will be significantly louder than the spindle itself.
