MILL-IT RANGE - THE MILL-IT-MINI

The small compact, stiff, rigid, robust, accurate, fast and flexible Mill-it-Mini CNC milling system from our Mill-it range. 


PRODUCTION AND PROTOTYPING HEAVEN

The Mill-it-Mini CNC milling machine system is designed with both production and prototyping in mind. The ballscrew drive system and industry specified high powered controller means the Mill-it-Mini can be a flexible prototyping tool – or – a full on production mini milling system


ACCURACY - 20 MICRONS

The Mill-it-Mini boasts full rolling element ballnuts and ballscrews. Coupling the ballscrews to high torque industry standard production specified stepper motors (NEMA 23) and associated controller – results in accuracy down to 20 microns. 


FAST, SMOOTH,RELIABLE, ACCURATE

The custom cast motor mounts, precision milled to final spec in vertical machining system, ensure perfect alignment. The Mill-it-Mini is fast, versatile, robust and one of the most accurate and powerful Mini Milling machines in it class.


FULLY ILLUSTRATED STEP BY STEP TUTORIALS

We take you on a  journey, from to grips with CNC, through to  advanced production work. We have developed a very comprehensive set of support videos and documentation, where every step is documented. Even the total CNC newcomer can learn to use the machine in a matter of hours.


UNMATCHED SUPPORT

We provide unmatched support for our systems. We cover every aspect of the machine ourselves. if you have any issues at all – we are there to help you. Don’t believe us have a look around the internet. You will find us helping out CNC users all over the world.


DESIGNED AND MANUFACTURED IN HOUSE

The Mill-it-Mini has been designed and manufactured exclusively in house. All non-standard parts are custom cast components and all are precision milled to very precise tolerances. But don’t take out word for it. Have look for yourself!

Accuracy and Performance

Watch the video of the Mill-it-Mini CNC milling machine to see actual drive performance without any backash software compensation.

  • Watch the video here to see actual drive performance
  • Each axis is cycled through a 9mm stroke
  • No backlash compensation settings were used
  • The axes were calibrated and then tested
  • The video shows actual mechanical drive performance
  • All three axes are shown to be within 0,01mm
  • Read below to see how to achieve this performance

NEMA 23 Motors

We offer the Mill-it-Mini CNC milling machine system with 1NM and 2NM NEMA 23 motors

  • Motor removal is hassle free and fast
  • The motors are IP54 rated with fitted cable-glands
  • Significantly improved cable management and motor protection
  • Motor replacement takes 2 minutes
  • Future upgrades to closed loop systems made easy

Custom precision machined motor mounts

The motor mounts that couple the stepper motors to the ballscrews in the Mill-it-Mini CNC milling machine are custom cast LM25 parts and precision CNC machined before installation. All Datum surfaces are made on CNC machining centre

  • A vertical machining centre (VMC) machines all datum surfaces
  • The motor mount holes, motor seating profile, structural mounting holes and thrust bearing insert pocket are all machined in one operation on the VMC
  • This ensures precision alignment between the motor, coupler, ballscrew and slides.
  • The motor seating profile machining ensures radial motor alignment

High stiffness core frame design

The Mill-it-Mini CNC milling machine’s core carcass is an LM 25 cast base with a Steel spine.

  • Custom designed LM25 cast base
  • All mounting surfaces precision machined
  • Welded steel spine – optimally welded for symmetrical cooling of weld joints
  • Steel spine and cast base form a rigit core machine structure

Double contact thrust bearings

In order to generate high milling forces you must lock the ballscrew in the direction of movement. The Mill-it-Mini CNC milling machine has two double angle contact bearings on each axis.

  • Ballscrew is custom machined to sit in a double angle contact thrust bearing
  • The outer race is held with a preload in the custom cast mount
  • The result is a very rigid end condition
  • 100% isolation of the motor from the feed force during machining
  • Thrust setup ensures no unwanted play or mechanical movement whatsoever in the direction of movement

Height adjustable 43mm mounting collar

  • The spindle mount is a 43mm mounting collar
  • Aluminium collar can be moved to change the height position of the spindle on the Z axis
  • Allows long cutters and work pieces to be accommodated
  • compatible with most 43mm mountable CNC accessories

Ballscrew drive system

A ballscrew is the best method for drive performance in a CNC milling machine and the Mill-it-Mini has a ballscrew on each axis.

  • The Mill-it-Mini is driven in all three axes by ballscews and ballnuts
  • A ballscrew drive is the most effective, efficient, and accurate way to drive a CNC system
  • The results is a drive system able to maintain positional accuracy when under machining loads down to 20 microns (0.02mm)
  • Ballscrews are very sensitive to alignment and setup. All the mounting surfaces are machined as datum surfaces on a precision vertical milling machine.
  • Therefore all alignment surfaces are made to very tight tolerances ensuring the ballscrews and ballnuts are perfectly aligned

High power industrial electronics

The control system controlling and driving the Mill-it-Mini Desktop CNC milling system is a very high spec industry standard controller.

  • These controllers and drives are industry standard and have been in our systems for years
  • The controller has a no volt release safety circuit – required for CE
  • EMC mains AC filter and industrial standard connectors fitted as standard
  • You can use the same control system as we use in the Mill-it-Mini to run a half sheet sized CNC router system

Industrial grade software and controller

We supply the Mill-it-Mini CNC milling machine with very robust and easy to use control software.

  • The video here shows the machine operation tutorial under UCCCNC control
  • The UCCNC controller is a fully windows compatible USB controller
  • We use the UCCNC controller on all our systems
  • Reliable, robust, and symmetrical pulse train generation for the motor amplifiers
  • The UCCNC software, USB 2.0 controller, and the industrial drive electronics give the Mill-it-Mini commercial production spec performance
