Machining center with abrasive blasting system

Abstract

A machining center with an abrasive blasting system is disclosed. The machining center includes a bed, a headstock mounted on the bed, and a carriage having a tool post. The machining center also includes an abrasive blasting system for imparting a predefined roughness to a surface of the work piece. The abrasive blasting system includes a reservoir, a pump, a tool and a nozzle. The tool is coupled to a tool post. The tool includes a conduit extending along a length of the tool for receiving the abrasive material therethrough. The nozzle is formed on a tip surface of the tool. The nozzle is configured to communicate to the conduit. The nozzle is adapted to discharge the abrasive material on the surface of the work piece during the machining of the work piece for imparting the predefined roughness on the surface.

What is claimed is: 
     
         1 . A machining center comprising:
 a bed;   a headstock mounted on the bed, the headstock comprises a spindle being driven by a power source and rotatable about an axis;   a work piece holder fastened to the spindle, the work piece holder comprises a plurality of jaws for holding a work piece;   a carriage mounted on the bed and moves along a longitudinal axis defined by the bed, the carriage comprises a tool post; and   an abrasive blasting system adapted to impart a predefined roughness to a surface of the work piece, the abrasive blasting system comprising:
 a reservoir for storing an abrasive material; 
 a pump in communication with the reservoir, the pump adapted to supply the abrasive material at a predefined pressure; 
 a tool defining a conduit therein, the conduit extends along a length of the tool and is adapted to receive the abrasive material therethrough, wherein the tool is coupled to the tool post; and 
 a nozzle formed on a tip surface of the tool and to communicate to the conduit, wherein the nozzle is adapted to discharge the abrasive material on the surface of the work piece during the machining of the work piece for imparting the predefined roughness on the surface.
