CNC Lathe Modification

page 1

   
Being able to mount the z-axis anywhere on the aluminum plate adds a lot of flexibility to the types of cuts that can be made. Sherline actually sells a bare plate with mounting holes for such a purpose. Here, I am temporarily mounting the z-axis in this location in order to cut the block of aluminum in half along the horizontal axis.
   
From the side, you can see the end mill cutting into the aluminum piece. A lot of material was wasted in making this cut because the diameter of the end mill was so large. It would have been better to use some type of band saw to split this aluminum block in half. However, at this stage I was more interested in experimenting with different type of cuts rather than the absolute practicality.
   
Here's a side view of the system configured as a mill. You will see later that I can convert this system into a lathe by repositioning the spindle and motor.
