The present invention discloses a wheel machining technology in which blank quantity is furthest removed by using a 90-degree external turning tool. Under the premise that the rotation direction of a wheel is unchanged, an upper trench of a groove is processed by using a left-handed special cutting-off cutter. Under the premise that the rotation direction of the wheel is unchanged, a lower trench of the groove is processed by using a right-handed special cutting-off cutter. The left-handed special cutter and the right-handed special cutter are added to the wheel machining technology disclosed by the present invention, so as to complete the processing of a groove of an outer wheel rim; a processing program can be pre-edited, so that processed effects conform to the design requirements of drawings of products.

A vertical rim trimming machine has a base, a horizontal sliding stand, a vertical sliding stand, a cutter turret, a bottom stand and a fixture. The horizontal sliding stand is mounted on and can horizontally move with respect to the base. The vertical sliding stand is mounted on and can vertically move with respect to the horizontal sliding stand. The cutter turret is mounted on the vertical sliding stand. The bottom stand is mounted on the base. The fixture is mounted on the bottom stand. Thus, the horizontal sliding stand horizontally moves with respect to the base stably and the vertical sliding stand vertically moves with respect to the horizontal sliding stand stably, such that the structure of the vertical rim trimming machine becomes firmer and the stability of trimming is improved.

The present disclosure relates to a rail vehicle that includes a chassis and a rail milling assembly coupled to the chassis. The rail milling assembly includes a bracket for coupling the rail milling assembly to the chassis and a milling workhead forming a portion of the rail milling assembly. The milling workhead including a spindle and a cutter depending downwardly from the spindle. The spindle and cutter are driven by a spindle motor. The milling workhead further includes a cylinder rod disposed between the spindle motor and the spindle to thereby bias the cutter towards the rail during operation.

A nozzle is arranged to provide coolant fluid to a cutting edge of a metal cutting tool. The nozzle includes at least one internal inlet coolant channel and at least one internal outlet coolant channel. The internal inlet coolant channel is connected to a coolant inlet and the at internal outlet coolant channel is connected to a coolant outlet for directing the coolant fluid to the cutting edge. The nozzle further includes a plenum chamber having at least one inlet opening connecting the internal inlet coolant channel and the plenum chamber and at least one outlet opening connecting the internal outlet channel and the plenum chamber. Each of the inlet openings have a cross-sectional area A1.sub.i and each of the outlet openings have a cross-sectional area A2.sub.i, wherein.sub.i=1.sup.nA1.sub.i>.sub.i=1.sup.mA2.sub.i, where i is an integer, n is the number of inlet openings, and m is the number of outlet openings.

An apparatus reconfigures or configures a wheel associated with a train. The apparatus comprises a tool configured to engage the wheel a compound slide system for positioning the cutting tool in at least two axes. The compound slide system is controlled so that the wheel is configured in accordance with a profile. The slide system can be moved mechanically and/or pneumatically and/or can use a mechanical profile. The apparatus can have a low profile and a low weight.
