Mill-it-Mega CNC milling machine features

When looking for a CNC milling machine you must consider a number of factors. Have a look below at what the Mill-it-Mega has to offer.

Machine travel and work area

The Mill-it-Mega CNC milling machine has a large travel area of X_700mm x Y_320mm x Z_250mm and a Tslot table size of 250mm x 1000mm.

  • Very high XY travel for a Milling machine in this class.
  • 700mm x 320mm in X and Y.
  • 250mm distance between bottom of collet and top of table
  • Anodised aluminium Tslot table is 1000mm x 250mm
Mill-it-Mega robust, rigid, stiff carcass

The Mill-it-Mega CNC milling machine carcass is incredibly rigid, robust and stiff which is vital for good surface finish during machining.

  • Main structure is the steel welded frame
  • Completed steel frame is fully heat treated
  • Frame is filled with polymer concrete resin
  • Frame is datum skimmed on all assembly and rail surfaces
  • The result is one of the stiffest frames of its kind.
  • The stiffness can be seen from the milling results
Precision milled Aluminium interplates for precise machine alignment during assembly

The precision milled interplates between the X and Y axes are machined in a vertical machining centre. All edges, are datum machined to maximise the alignment during assembly. 25mm thick Aluminium sections maintains the machines core stiffness.

  • 25mm Aluminium plates for high stifness
  • All plates precision milled on a VMC
  • All assembly edges datum machined
  • Designed for easy assembly
  • Straight forward adjustment to ensure X is square to Y
  • Very high quality, accuracy and stiffness in the coupling of the X to Y axis
Nema 34 4NM stepper motors driving the ballscrews

The standard config of the Mill-it-Mega CNC milling machine is Nema 34 4NM steppers with IP54 rated sealing caps on the ends of the motors. High stepper motor drive voltage results in high torque.

  • Stepper motor torque directly related to operating voltage
  • Mill-it-Mega runs on high powered 75V DC stepper drives
  • IP54 rated NEMA 34 4NM motors (rapids up to 4000mm/min)
  • All cables EMC shielded and high quality shroud also
  • High power Delta 400W Servo option available with rapids of up to 10,000mm/min
IP67 rated high quality inductive limit / home sensors

With a machine like this often collant in either flood or mist configuration will be needed. The IP67 rated induction sensors are very robust and high quality.

  • IP67 rated sensors
  • 12V DC operating inductively so very reliable
  • High quality sealed can connector to sensor
  • PUR cable coating for very long cable life in harsh environments
  • Each axis has one sensor
Mill-it-Mega Spindle options

The Mill-it-Mega CNC milling machine standard spindle options are 12-24000RPM spindles. These spindles are all aircooled and are excellent for machining alloys at high speeds and high material removal rates.

  • 0.75kW 2kW and 3kW options
  • Collets: 0.75kW has ER20 | 2kW has ER25 | 3KW has ER32
  • All spindles have double angled contact bearings in nose and tail
  • All spindles are fully balanced after a 12 hour run in period
  • All spindles come with a fully balanced collet nut
  • Driven through a VFD so all fully on/off and speed controlled with software
  • 0.75 and 2kW run on single phase. The 3kW needs three phase
  • All spindles have full stated power output down at 12000RPM. These spindles are well suited to high feed rates with cutters even as low as 6mm. Typically milling systems with spindle speeds less than 8000RPM required very slow feed rates when using smaller cutters.
  • Fully up-gradable – all spindle options fit the mount on the machine so its no problem to start small and upgrade later
