Presented mechanism is part of acrylic mill. It is presented separately due to highweight of 3D models.
Aim: Mill construction with 18.000RPM spindle to chamfer acrylic plates.
Mill has been designed for HOMAG company. It has author’s solution for moving spindle up and down arround virtual rotation axis. 4-link mechanism has been shown below, in 3D models. Mechanism is capable to set horizontal tilt angle on spindle, to set bumpers in 2 dimensions, to set thickness od milled acrylic. Elastic rollers with pre-set pressure and belt conveyor with automatic tensioner provide travel speed regulation. Explore 3D model below!
