Abstract
An apparatus for profiling a wheelset comprised of a milling cutter with a first axis of rotation, driven friction rollers for rotating the wheelset about a second axis of rotation, and computer numerical control apparatus for rotating the milling cutter about its first axis of rotation while disposing it so that the first axis of rotation is substantially perpendicular to the second axis of rotation.
Claims14
An apparatus for profiling a wheelset of railroad vehicles comprised of a milling cutter, wherein said milling cutter is comprised of a body with a first axis of rotation, and wherein:
- (a) said apparatus is comprised of means for rotating said wheelset about a second axis of rotation which comprise driven friction rollers,
- (b) said apparatus is comprised of computer numerical control means for rotating said milling cutter about said first axis of rotation while disposing said milling cutter so that said first axis of rotation is substantially perpendicular to said second axis of rotation,
- (c) said milling cutter is comprised of a body with a first edge crown attached to a first portion of said body at a first distance away from said first axis of rotation, and a second edge crown attached to a second portion of said body at a second distance away from said first axis of rotation, and
- (d) said first edge crown is attached in a first cutting direction, said second edge crown is attached in a second cutting direction, and said second cutting direction is opposite to said first cutting direction.
A process for stock-removal profiling of wheelsets of railroad vehicles with an apparatus for profiling a wheelset of railroad vehicles comprising a milling cutter, comprising the steps of:
- (a) rotating said milling cutter about a first axis of rotation, wherein said milling cutter is comprised of a body with said first axis of rotation,
- (b) disposing said wheelset with said second axis of rotation so that said second axis of rotation is substantially perpendicular to said first axis of rotation while simultaneously rotating said wheelset by means comprising driven friction rollers and contacting said rotating wheelset with said rotating milling cutter, wherein:
- 1. said milling cutter is comprised of a body with a first edge crown attached to a first portion of said body at a first distance away from said first axis of rotation, and a second edge crown attached to a second portion of said body at a second distance away from said first axis of rotation, and
- 2. said first edge crown is attached in a first cutting direction, said second edge crown is attached in a second cutting direction, and said second cutting direction is opposite to said first cutting direction.
