Over the last 60 years, RAFAMET has developed a broad range of machining tools, including special-purpose wheel lathes for railways, metro, tram, and other light-rail transit systems, heavy-duty single and double-column vertical turning and lathes, large bridge-type milling machines, horizontal lathes and special machines.
The company's Integrated Quality, Occupational Health and Safety and Environmental Management System is certified under ISO 9001: 2000, ISO 18001 and ISO 14001: 2004.
The RAFAMET machine tools for wheelsets incorporates design features based upon the most recent achievements in machine tool design and economical wheelset machining techniques.
CNC underfloor wheel lathes
Available in both single and tandem versions, the machines are designed for turning of wheel profiles and facing of brake discs of one or two wheelsets at the same time.
The machines are set below the rails. Permanent and retractable rails, which connect with the floor rails to form a track, allow the vehicle to travel over the machines. Their basic body element is extremely rigid, single-piece, heavily ribbed, high-grade grey iron casting, which provides perfect vibration dumping for improved machining accuracies and productivity rates.
The machines are equipped with the unique wheelset supporting and driving system consisting of independent and flexible drives of each driving roller, in order to ensure constant contact between the rollers and the wheels and guarantee the driving torque is efficiently transmitted.
The saddles, equipped with the reliable measuring heads and tool holders, travel along the cross-rail, horizontal, hardened and ground guideways. The machines can be provided with many optional elements and devices, including vehicle shunting / winching arrangements, as well as dust extraction and swarf evacuation systems.
The single UGE 180 N and tandem 2 UGE 180 N are designed for machining the wheelsets of subway and light railway vehicles and wagons of axle loads up to 18t.
The single UGE 300 N and tandem 2 UGE 300 N are designed to machine the profiles of the wheelset wheels of heavy rail vehicles of axle loads up to 30t. The machines can be operated for up to 40t applications.
Rail-road shunting vehicle
The Rafamet 3RS rail-road shunter is designed to shunt the rolling stock and other vehicles with a maximum total mass up to 350t.
It can operate both on rail tracks as well as roads and other flat surfaces of the production floors, manoeuvring areas and loading platforms within the enclosed industrial premises (such as railways, metros, tram depots and ports). The shunter can be used as auxiliary equipment of the underfloor wheel lathes.
CNC portal wheel lathes
The RAFAMET portal wheel lathes are built on the base of extremely rigid, single-piece, heavily-ribbed, high-grade grey iron casting of the main structure in the form of a portal allowing operation in roll-through systems and providing efficient chip disposal.
The UFD 140 N equipped with a friction roller main drive is intended for heavy cutting of wheelset wheels with tread diameters ranging from 540mm to 1,400mm. The wheelset is driven by wheel flanges.
The UDA125 N with chuck-type radial or axial wheelset clamping system is designed to machine the wheelset wheels used in rail vehicles. Maximum wheelset tread diameter is 1,250mm and the maximum length of wheelset axle is 2,370mm.
CNC surface wheel lathes
RAFAMET surface wheel lathes are able to execute operations, including turning wheel profiles according to a technological programme, facing of brake-disc friction surfaces and turning of wheel centres.
The UFB 125 N is a wheel lathe with friction roller drive. The machined wheelset is driven in a double system of three rollers attached to wheel treads.
The UBF 112 N, intended for machining wagon wheelsets of tread diameters up to 1,120mm, is provided with a main drive consisting of two 28kW AC motors of continuously variable rotations, operating in a master slave system.
The UBE 150 N is intended for locomotive wheelsets of tread diameters up to 1,250mm. The lathes are adapted to roll in and roll out the wheelset on the same side.
CNC wheel boring machine
The KCM 150 N wheel boring machine is designed to execute operations such as rough and finish turning, and boring of holes, on both solid railway wheels and tyres, according to a technological programme.
This machine is equipped with a turning railhead travelling horizontally along crossrail, allowing users to avoid the time-consuming exchange of tool bars for different hub bore sizes. The railhead cooperates directly with the automatic tool magazine.
The KCM 150 N is equipped with a wheel measuring probe, and an oil injection hole drilling attachment can be also supplied.
CNC axle lathe
The TOK 80 N is a slant-bed horizontal lathe for rough and finish turning of new and worn railway axles. The machine tool can also perform burnishing operations for improved surface hardness and quality.
Gantry milling centre
The GMC-320 CNC is a gantry milling centre for machining railway bogie frames.
