 +The M250 is a full-function machine capable of the entire range of turning operations, and through the available range of 
 +accessories its scope and versatility can be increased even further. Quality, reliability and response make it one of the most 
 +outstanding lathes of its kind especially in industry, the toolroom, training and secondary and tertiary education.\\ 
 +  *Easy to understand headstock mounted speed, threading and feed charts\\ 
 +  *Smooth power transmission through a twin vee belt drive and induction hardened and ground headstock gearing\\ 
 +  *Large saddle and slide bearing areas for precision and long life\\ 
 +  *Deep section top slide with dovetail guides and gib strip adjustment\\ 
 +  *The combination box section cast iron bed and rigid steel base provides an incredibly strong structure\\
