    Plug and Play Operation
    Effortlessly integrates with all current Avid CNC electronics systems and kits.
    Powerful Performance
    A wide operating range from 1,000 to 24,000 RPM, ensuring optimal performance for a variety of materials and applications.
    Optimized for Production
    Designed for continuous use in demanding production environments. The spindle's electric cooling fan ensures reliable operation at lower RPMs.
    ER32 Collet System
    ER32 collets accommodate up to 3/4" shank tooling.
    Adaptable Power Requirements
    Compatible with 3-phase 208VAC[1] or single-phase 240VAC[2]. The system fits to the power configurations of your shop.
    Comprehensive User Guides
    Access to elegantly detailed user guides and step-by-step instructions for simple assembly and setup.
    Engaged Maker Community
    Join a vibrant online community of thousands of Avid CNC Users and Makers for support and inspiration.
    Proudly designed, produced, and supported in the USA by Avid CNC

    Product Options / Configuration

    The compatibility options available include additional components for integrating this system with our previous CNC electronics systems, or with DIY CNC electronics.

    EX & CRP800 Controllers
    Our current EX and previous Plug and Play CRP800 CNC Control Systems are "Spindle Ready" and require no additional components to work with this Spindle / VFD system.
    CRP500
    This option includes a gland connector for integrating with either our previous NEMA 23 Plug and Play Systems (systems with CRP5042 digital drivers that were built prior to February 2015).
    CRP300
    This option includes an additional PMDX-107 Isolated Speed Control card and gland connector for integrating with our previous NEMA 34 Plug and Play Systems (systems with Gecko G201X or G203V drivers, and PMDX-126 breakout board).

    Technical

    Spindle Comparison

    Evaluating the Material Removal Rate (MRR) is an indicator of the efficiency of a cut. This is a combination of depth-of-cut, width-of-cut, and feed rate. The increased power of our 8.7 HP (6.5 kW) Spindle / VFD system allows for higher MRRs and increased production.

    Comparison tests were conducted in maple hardwood with a PRO CNC machine, NEMA 34 motors, and an Amana RC-2241 1.5" tool. Chipload was set to the tool manufacturer's recommended maximum of 0.008 inches per tooth.

    Product Notes

    1. Three-phase 200-240VAC power must be a three-wire or four-wire Wye system. Three-phase 380-480VAC power must be stepped down to three-phase 200-240VAC (typically 208VAC). Additional information can be found in our Spindle / VFD System Power Requirements.
    2. Operating the 8.7 HP (6.5 kW) Spindle / VFD system on single-phase power will reduce the spindle's peak horsepower to 6.4 HP (4.7 kW), and the achievable material removal rate may be reduced by up to 27% depending on the material, tooling, and cutting parameters used. A three-phase to single-phase plug adapter is included for use with NEMA L6-30 receptacles. For single-phase applications, a 30A 220V circuit is required.
