Abstract

A concentric coaxial cutting machine which cuts cylinders, cylindroids or cones using a chain saw from a single larger object such as a wood tree trunk, a block of ice or a block of plastic. An embodiment of the invention comprises a transverse support member having directly or indirectly mounted thereon; a headstock member including; a headstock spindle member mounted to said headstock member including; a drive spindle rotationally mounted to said headstock spindle member and adapted to rotationally retain one end of an object to be centrically cut; a tailstock member including; a tailstock spindle member mounted to said tailstock member including; a tailstock spindle rotationally mounted to said tailstock spindle member and adapted to retain an opposite end of the object; a drive assembly in rotational communication with the drive spindle and adapted to rotate said drive spindle around a common axis with said tailstock spindle; and, a first chain saw variably aligned at an angle to said common axis and adapted to concentrically cut the object from at least the opposite end.

A concentric coaxial cutting machine comprising:

a longitudinal support member;
a transverse support member coupled to said longitudinal support member including;
a headstock member including;
a headstock spindle member coupled to said headstock member including;
a drive spindle rotationally mounted to said headstock spindle member and aligned to rotationally retain one end of an object to be concentrically cut;
a tailstock member coupled to said longitudinal support member including;
a tailstock spindle member coupled to said tailstock member including;
a tailstock spindle rotationally mounted to said tailstock spindle member and aligned to retain an opposite end of said object;
a drive assembly in rotational communication with at least said drive spindle and configured to rotate said drive spindle about a common longitudinal axis with said tailstock spindle;
a first chain saw variably align-able at an angle to said common longitudinal axis such that said chain saw engages said object from at least said opposite end;
and,
wherein said tailstock spindle member is pivotally connected to said longitudinal support member so as to be repositionable about a long dimension of said longitudinal support member.
