Tool coolant application and direction assembly

Abstract

A coolant assembly for supplying coolant fluid to a tool includes an outer ring defining an inlet and an insert pressed within the outer ring including an annular channel. The annular channel is in communication with the inlet defined by the outer ring and includes a plurality of passages disposed to direct fluid along an axis of a tool. At least two of the passages are disposed at different angles relative to the axis of the tool to direct coolant along the entire length of the tool in order to provide a uniform and consistent stream of coolant and uniform and consistent temperature of the tool.

       9 . The assembly as recited in  claim 1 , wherein said angle of said coolant openings is between 2° and 25° relative to said axis.  
   
   
       10 . The assembly of  claim 1 , further including a fluid supply collar coupled to said body portion for supplying coolant fluid to said channels.  
   
   
       11 . The assembly as recited in  claim 1 , wherein said channel further comprises a sleeve disposed about said body portion forming a portion of said channel in cooperation with said passages disposed adjacent an outer periphery of said body portion.  
   
   
       12 . A tool holder assembly for mounting a tool comprising; 
 an inlet for supplying coolant; and    a body for mounting the tool along an axis, said body portion including a coolant channel communicating coolant from said inlet to a plurality of coolant passages, said cooling channel disposed longitudinally along an outer perimeter of said body.    
   
   
       13 . The assembly as recited in  claim 12 , wherein said inlet is disposed along said axis to an opening adjacent a rear end of said body.  
   
   
       14 . The assembly as recited in  claim 12 , wherein said body includes a face transverse to said axis, said face including an annular channel and an insert disposed within said annular channel.  
   
   
       15 . The assembly as recited in  claim 14 , wherein said insert includes said coolant passages.  
   
   
       16 . The assembly as recited in  claim 15 , wherein said coolant passages are radially spaced from an opening for the tool.  
   
   
       17 . The assembly as recited in  claim 16 , wherein said spacing is between 0.1 inch and 0.5 inches.  
   
   
       18 . The assembly as recited in  claim 17 , wherein said body includes a tapered portion.  
   
   
       19 . The assembly as recited in  claim 12 , including a coolant nut and a collet within said body, said coolant nut including said cooling holes and said collet including a groove defining a portion of said coolant passages to said cooling holes.  
   
   
       20 . The assembly as recited in  claim 19 , wherein said collet includes a face and a groove disposed on said face for establishing a portion of said cooling passages to said cooling holes.  
   
   
       21 . A tool holder assembly for mounting a tool comprising; 
 an inlet for supplying coolant;    a body defining a coolant inlet; and    a coolant nut engaged to said body and including a plurality of coolant openings receiving coolant from said coolant passage.    
   
   
       22 . The assembly as recited in  claim 21 , including a collet disposed within said body for mounting the tool along an axis, said collet defining a portion of a coolant passage from said coolant inlet  
   
   
       23 . The assembly as recited in  claim 22 , wherein said collet includes a face transverse to said axis, said face including a groove defining a portion of said coolant passage.  
   
   
       24 . The assembly as recited in  claim 21 , wherein said body includes a flange and said coolant inlet is disposed within said flange.  
   
   
       25 . The assembly as recited in  claim 21 , wherein said body includes an end and said coolant inlet is disposed adjacent said end.  
   
   
       26 . The assembly as recited in  claim 21 , wherein said coolant openings within said coolant nut are angled relative to said axis such that coolant is directed at said tool.
