Abstract
Machining on lathe with counter spindle enables to machine free form surfaces with any
intervention during the process. Machining technology on lathes with counter spindle
using multiple-axis machining and a description of machining of 5-axis turning centre with
the counter spindle CTX - Alpha 500 is briefly mentioned in the article. Machining centre is
located in the Centre of excellence of five axis machining at Faculty of Materials Science and
Technology in Trnava and it is intended for research on technological possibilities of 5-axis
machining and free form surfaces machining.
