Abrasive block for machining rails

Abstract

Vehicle for machining a rail by grinding and/or planing, including a mobile chassis and a metal abrasive module for grinding and/or planing the rail, the metal abrasive module including an eccentric drive performing an eccentric movement, at least one abrasive block mechanically connected with the eccentric drive and a force exerting drive pressing the abrasive block onto the rail, wherein the abrasive block and/or the metal abrasive module has a first hollow channel. This allows a more effective and improved metal removal and rail shaping capabilities, including the delivery of fluid i. a. for cooling.

1 . Vehicle for machining a rail by grinding and/or planing,
 comprising a mobile chassis and a metal abrasive module for grinding and/or planing the rail, the metal abrasive module comprising:   an eccentric drive performing an eccentric movement;   at least one abrasive block mechanically connected with the eccentric drive;   a force exerting drive pressing the abrasive block onto the rail,   wherein the abrasive block and/or the metal abrasive module has a first hollow channel.   
     
     
         2 . Vehicle according to  claim 1 , wherein the channel extends substantially perpendicularly to the direction of the rail. 
     
     
         3 . Vehicle according to  claim 1 , wherein the first hollow channel has a first opening and a second opening. 
     
     
         4 . Vehicle according to  claim 1 , wherein hollow channel is filled with a coolant and/or fluid and/or the hollow channel is configured to guide a coolant and/or fluid. 
     
     
         5 . Vehicle according to  claim 1 , wherein the first hollow channel is configured to guide a coolant and/or fluid to a contact surface of the abrasive block with the rail. 
     
     
         6 . Vehicle according to  claim 1 , wherein the first hollow channel is configured to allow suction of debris and/or metal chips from the rail and/or from the environment of the rail. 
     
     
         7 . Vehicle according to  claim 1 , wherein the abrasive block and/or the metal abrasive module has a second hollow channel with a first opening and a second opening. 
     
     
         8 . Vehicle according to  claim 1 , wherein the second hollow channel is configured to guide a coolant and/or fluid to a contact surface of the abrasive block and/or the metal abrasive module with the rail and/or the second hollow channel is configured to allow suction of debris and/or metal chips from the rail and/or from the environment of the rail. 
     
     
         9 . Vehicle according to  claim 1 , wherein the first hollow channel and/or the second hollow channel has a section extending substantially vertically and/or has a free-formed section. 
     
     
         10 . Vehicle according to  claim 1 , wherein the first hollow channel and/or the second hollow channel have an opening on top and on the bottom of the abrasive block and/or the metal abrasive module. 
     
     
         11 . Vehicle according to  claim 1 , wherein the abrasive block is manufactured by hot embossing and/or additive manufacturing and/or chemical etching techniques. 
     
     
         12 . Method for machining a rail by grinding and/or planing, comprising the steps of:
 approaching the surface to be machined until contact with a metal abrasive module having at least one abrasive block, wherein the metal abrasive module is mounted on a vehicle;   performing movements with the abrasive block while pressing the abrasive block onto the rail;   guiding a fluid and/or a coolant to the contact surface of the rail and the abrasive block through a first hollow channel in the abrasive block.   
     
     
         13 . Method according to  claim 12 , further comprising the step of suction of debris and/or metal chips in the vicinity of the abrasive block through the first hollow channel. 
     
     
         14 . Method according to  claim 12 , further comprising the step of alternating suction of debris and/or metal chips in the vicinity of the abrasive block through the first hollow channel and guidance of coolant through the first hollow channel. 
     
     
         15 . Method according to  claim 12 , further comprising the step of suction of debris and/or metal chips in the vicinity of the abrasive block through a second hollow channel within the abrasive module.
