CNC TURN MACHINE
Great experiences with CNC technology and many parts on stock begun idea create own little CNC turn machine. Simple design and help CAD system speed up procces of construction. Main spindle have turn head 125/3 and turning place 280mm, with 3-phase motor with frequential invertor. For movements are used linear bearings THK 20mm and 35mm. Ball screws are connected with coupling with 2-phase stepper motors with 2.8 Nm force. Tool head are from big turn machine and have 4 post ( dimension 125x125). Stepper are connected via drivers M542 to breadboard through cable DB25 (parallen cable). On machine missing opposite support, because its for short parts from aluminium and alloys.
