Desktop milling machine with ovate-shaped bridge

Abstract

The desktop milling machine with an ovate-shaped bridge is a desktop milling machine of the computer numerical control (CNC) type having a portion of the bridge or frame structure configured to alleviate bridge deflections and deformations that are caused during the high-speed milling processes. Preferably, the bridge has an ovate arch, or has a rear face having an ovate contour.

I claim: 
     
         1 . A desktop milling machine, comprising:
 a bridge member having a front face and a rear face, a portion of the bridge member having an ovate configuration;   a platform, the bridge member being supported on the platform; and   a high speed milling machine spindle mounted on the front face of the bridge member.   
     
     
         2 . The desktop milling machine according to  claim 1 , wherein said bridge member has an opening formed therethrough, the opening being of an ovate configuration. 
     
     
         3 . The desktop milling machine according to  claim 1 , wherein the rear face of said bridge wall has an ovate configuration. 
     
     
         4 . The desktop milling machine according to  claim 1 , wherein said high speed milling machine spindle is vertically adjustable. 
     
     
         5 . The desktop milling machine according to  claim 1 , further including a plurality of legs formed on said bridge member and supporting said bridge member on said platform. 
     
     
         6 . The desktop milling machine according to  claim 1 , wherein the desktop milling machine is a computer numerical control (CNC) milling machine. 
     
     
         7 . A desktop milling machine, comprising:
 a bridge member having a front face and an opening formed through the bridge member, the opening having an ovate configuration;   a platform, the bridge member being supported on the platform and bolted thereto;   a high-speed milling machine spindle mounted on the front face of the bridge member, the opening being positioned beneath the high-speed milling machine spindle.   
     
     
         8 . The desktop milling machine according to  claim 7 , further comprising a workpiece holder, wherein said workpiece holder is horizontally adjustable along two orthogonal axes. 
     
     
         9 . The desktop milling machine according to  claim 7 , further including a plurality of legs formed on said bridge member and supporting said bridge member on said platform for secure kinematic support thereof 
     
     
         10 . The desktop milling machine according to  claim 7 , wherein the desktop milling machine is a computer numerical control (CNC) milling machine. 
     
     
         11 . A desktop milling machine, comprising:
 a bridge member having a front face and a rear face, the rear face having an ovate contour;   a platform, the bridge member being supported on the platform and extending vertically upward therefrom; and   a high speed milling machine spindle mounted on the front face of the bridge member, wherein said high speed milling machine spindle is selectively vertically movable.   
     
     
         12 . The desktop milling machine according to  claim 11 , wherein said bridge member and said platform form an L-shaped profile. 
     
     
         13 . The desktop milling machine according to  claim 12 , wherein the desktop milling machine is a computer numerical control (CNC) milling machine. 
     
     
         14 . The desktop milling machine according to  claim 11 , further comprising a workpiece holder, wherein said workpiece holder is horizontally adjustable along two orthogonal axes.
