MRT25 Motorized Rotary Table

These rotary tables are used for many kinds of heavy machining and precision turning, capable as a 4th axis.  Load capacity is huuuge 42,000 pounds! Other uses are precision applications such as laboratory, production part rotation, inspection, indexing to precise angles, laser marking, angular testing and measurements.

Robust as a stand-alone unit with several modes to automate your rotation and indexing, and controlled by other CNC controllers for additional mult-axis sequences.  Excellent repeatability due to the high precision spur gears.  Total runout is less than .002 inches, typically as small as .001.

Smaller pictures show mounting the X86-118 underneath the table, and with optional 2nd X86-118 and gearboxes. Dual motors give twice the torque and force, and more than 2X accuracy. Price shown above does not include 2nd motor and gearbox. contact us for pricing.

Every Excitron rotary table can be mounted horizontally or vertically since the thick grease will not run out.  The steel inner mounting ring makes it easy to mount anywhere.

Includes NEW DRO Digital Readout display, mounted on motor. Makes your operation incredibly wonderful! Gives you instant display of degrees to 4 decimal places. The DRO shows most motor parameters at a glance, also RPM. You can connect a smart phone or PC, using the USB adapter we give you. 2 nice methods:

  • Use smart phone or PC.
  • you can type N, number of steps to rotate, and type G for Go.
  • the number of motor halfsteps per revolution is 194,400, with 486:1 gear ratio, which is 540 motor steps per degree.
  • if you want to move 30 degrees, then you type in N then 0016200. 16200 is 30 deg x 540 steps/deg.
  • then type G for Go.
  • keep the smart phone plugged in to make any rotation you want.
  • BEST--use built-in Joysticks.
  • use smart phone once, to change the values for each of the 10 Joystick switches to the angles you want, then unplug the phone.
  • example: change the Motion Profile for Joystick J1 to N=0002700. 2700 is 5 deg x 540 steps/deg.
  • then each time you push J1, the table rotates that direction exactly 5 degrees.
  • then change J2 to 15 deg, J3 to 45 deg, and J4 to 90 deg.
  • then do the same for Joysticks J6, J7, J8, and J9, for other direction.
  • J5 is already set to continuously rotate forever. You can stop the motor by pushing center Joysticks J5 or J10.
  • Now you have any 4 angles, plus continuous, in both directions!
  • If you only go in one direction, then you can set all 10 switches for same direction, and then have 10 different angles.
  • By the same method, if you hook up 2 of our SW1-2D handy external waterproof switches, then you can have 4 more, a total of 14 rotation angles.  that's more different angles then most customers need.
  • Example: if you need to drill 12 holes, 30 deg apart, that can be done with just one switch.  set N=0016200 for 30 degrees (assumes 486:1 ratio), and set R repeat to 00011, which is run once, then repeat 11 times. set little t=05000 (for example) to pause 5 seconds in between so can drill a hole. you can set the time delay from 1 millisec to 65+ seconds.
  • then unplug the smart phone, never needed again, except for changing values.
  • With the Joystick method, nothing is dangling, no smart phone, no keypad. you can do all of the above using a laptop or PC, too. The DRO shows you degree, and the X command allows you to set any angle for your reference.

    Look in Serial Programs for all serial communication details. We highly recommend a new serial communication app named Serial USB Terminal by Kai Morich. Download and install this app by using Google Play Store. Works well with our USB-TTL-3pin adapter. It also works with Arduino with CDC driver. The Settings tab on the app is intuitive and easy to set for 115,200 baud, no parity, 8 data bits, 1 stop bits. wonderful!

    All MRT6, 8, 10, 12, 16, 20, 24, 25, 30, and 39 inch rotary tables are CNC ready-to-go systems, and include:

    • Heavy-duty steel rotary table with quick mount T-slots
    • Precision stepper motor and integrated controller with built-in 10 Joystick switches for 10 independent standalone motions.
    • Motor and gear drive use ultra-precision spur gears and are fully enclosed.
    • 2 TTL 3.3v serial ports built-in, and one 39" (1m) USB-TTL-3pin adapter serial cable.
    • Two 4 inch cables with 3 pin housing and crimps for general DIY inputs, unwired at open end.
    • 24 volt AC/DC power supply and AC cable, 50/60 hz, 100-240 VAC, works anywhere in the world.
    • One set of T-slot nuts for clamping.
    • One set of screws and nuts for securing your base, HV tables include clamp bars.
    • Key ring with 10 metric hex key wrenches, 1.5 to 10mm.
    • 12 x 20 inch high temperature transparent silicone sheet for water spray protection.
    • Pre-packed for life with top quality high pressure black Moly-Lithium grease/lubricant.

    Nothing else is necessary.  Browse Documentation link on home page for 3D solid models and other files.

    Gold plated connectors and printed circuit boards for ultimate reliability, heat flow, and performance.  Each Controller is fully integrated with the stepper motor, producing the most compact and powerful intelligent motor drive available.  All X Controllers use exactly the same command set, to give you simplicity.  These units offer the first total 100% motor drive solution, allowing easy plug-n-play for machines, CNC, robots, actuators, vehicles, and all equipment.

    You easily control how your stepper motor operates in these modes:

    • Serial Commands:  send and receive via USB using the included USB-TTL-3pin cable adapter, connect directly to arduinos and microcomputers.  Connection with PCs, PLCs or Labview work well.
    • 2 built-in Joysticks:  10 different motions built-in, and are changeable.
    • Home:  Home command H runs Motion Profiles 02-05, exactly as you need.  You can also set the Repeat Home feature, whereby Home repeatedly runs 4 Profiles at power-up over and over.  In this case, your computer is not needed.  You can use also inputs to control how and when these profiles run.
    • Input Profile Mode IPM:  each of the 4 input pins give you random selection of 3 motion profiles each, by simply pushing external switches or external control signals.  In2 and In3 are analog or digital.
    • Driver (CNC step/dir):  motor steps each time when an external STEP occurs, in the direction set by DIRECTION.  CNC programs usually output these signals on a PC parallel port.
    • CNC/Gcode:  run 1-8 Excitron motors using popular Gcode.  One Excitron motor is the master sending TTL serial commands to other Excitron motors.  Master motor can read, view, save, and run Gcode files.

    See X86 motor webpage for more details.

    You can combine many of these modes, with few restrictions.  All modes allow changing motor speed on-the-fly using J1 and J4, then can save the new speed by pushing J2 while running .  Hundreds of successful customers have created very ingenious motion using these simple "building blocks", as short as 10 minutes.  You can add intelligent repetitive motion to almost any machine.

    Optional Outer Ring Cover protects gear teeth and acts as finger guard. Contact us for price. Finger guards must be provided for safety. Customers usually add aluminum extrusions or build the rotary table into their equipment.

    All Excitron size 86mm stepper motors have 400 half-steps per shaft revolution, and the 132:1 gear ratio gives you an incredible 52,800 steps per table top revolution. This very high resolution is 0.0068 degrees per half-step. Stepper motor top speed is over 8,000 half-steps/second, as high as 9,000 sps with lighter loads.

    Gear backlash is virtually zero and you can readily adjust backlash and tightness. Usually backlash is +-.002", and even this can be compensated for electronically in CNC programs to reduce backlash to zero.

    Our stepper motors and controllers give you great speed and torque, and many large companies have purchased these for automating various motions.  Click on Testimonials button above.
