Question: [1/2" Lead Screw (2 turns per inch)] Maximum length of 1/2 inch lead screw

Current Solution

Depending on the size of your CNC machine, it will vary the length required for your application.
Please verify the CNC machine, and we can go into detail on the specific lengths or methods for the linear guide mechanics.

We sell our ACME Screw (1/2" per inch), also our longest length of ACME Screw is 76-3/4".

  • how do you calibrate steps per inch using Mach3 and a 1/2x13 lead screw

    You will first need to derive the number of turns per inch that your lead screw produces. If there is only a single start (typical all thread screws), then the turns per inch is the same as TPI (threads per inch). If there is multiple starts, then the number of starts is divided by the TPI to determine the turns per inch. For example, 10 TPI with 5 starts is 10 / 5 = 2 turns per inch. Now that we know this, we can get the number of steps per inch as described in the previous question: take the number of steps per revolution that the motor will output. This will be the number of full steps that you motor produces (typically 200, or 1.8 degrees per step) multiplied by the microstepping per step to which the driver is configured. Simply multiple the number of turns per inch and the number of steps per revolution and you will get the steps per inch. Ok, lets see the formula:

    200 steps * 16 microsteps * 2 turns per inch = 6400 steps per inch

  • Can 3/8" lead screw be used instead of 1/2" on the 'BOOK' machine?

    Yes, you will only need to change the coupling that couples the motor to the 3/8" lead screw.

  • With a 1/2 lead screw what is the optimal steps for the stepper motor driver 1/16, 1/8, 1/4 etc

    We typically use a 1/4 microstepping for lead screws, but you want to determine the microstepping only after you determine what resolution you want on that axis of the machine.

    The formula:
    Resolution is steps per inch or steps per milimeter

    I will go over this using steps/inch:
    steps = motor steps x driver microstepping
    inch = the amount of travel with one full stepper motor rotation

    In the case of our 1/2" 5 start 10 TPI lead screw, the axis will travel .5 inches with one stepper motor rotation.

    Let's use 1/4 microstepping (4 microsteps for each stepper motor step)

    Therefore:
    (200 steps x 4) / .5 inches =
    800 steps / .5 inches =
    1600 steps/inch

    Now let's use 1/2 microstepping (2 mistrosteps)

    (200 steps x 2) / .5 inches =
    400 steps / .5 inches =
    800 steps/inch

    Remember that increasing microsteps, the torque is also reduced, but the smoothness from the motor is increased.

  • HI, I HAVE INTENTION OF PURCHASING YOUR 1/2 INCH PRECISION LEAD SCREW SET TO BUILD MY CNC MACHINE, COULD THE SCHEMATIC DIMENSION ANTI-BACKLASH NUT, BEARING FOR AND SHIM? ALSO IS 2.2KW SPINDLE ABLE MILL ALUMINUM WHAT ACCURACY?

    BYCNC response:

    Milling aluminum is no problem with our machines.

    Here is a video we recently did with our 4'x8' machine. The aluminum piece is about 1/4" thick: https://buildyourcnc.com/tutorials/tutorial-greenbull-aluminum-cutting

    The accuracy you will see from our our 2.2kW spindle is entirely dependent on the precision of your build, so it's not possible to say what level of accuracy you can achieve without an examination of the complete system. However, our spindles have a runout of less than .0001 in, which includes the collets that we sell. If you use a collet from another manufacturer, we cannot guarantee this TIR (Total Indicated Runout) dimension.

    For the dimension drawing of the anti-backlash nut, please contact us directly by phone or email to techsupport@buildyourcnc.com
