Станкостроительны завод «ТБС» ПР622Ф4

The PR622F4 is a specialized CNC horizontal boring machine developed and manufactured by the St. Petersburg-based TBS Machine Tool Plant. This heavy-duty machine is designed specifically for the needs of railway transport and transport engineering. It is intended for high-precision machining of key and critical rolling stock components. Thanks to specialized equipment, one such complex replaces a production line of 12 obsolete machines. WorkpiecesThe machine is used to process technological and operational surfaces of the following units:Axlebox housings and bolstersHousings, locks and lock holders of automatic couplingsNon-rotating shoes and safety devicesTraction clamps and centering beamsSide frames of freight trolleysDesign featuresHigh precision: the movements of moving units are controlled by precision feedback sensors along the X, Y, Z and W axes.Rigidity and stability: reliable hydraulic clamps ensure that the units are fixed in specified positions.Combined guides: sliding pairs (cast iron-TsAM/fluoron) are used along the X and Y axes together with hardened steel lateral rolling bearings.Precision ball screws: high-quality ball screws are used for smooth and precise linear movement of the units transmission. Rotary table (B axis): equipped with an automated precision stop system at positions 0, 90, 180 and 270 degrees. Protection of units: telescopic covers completely cover the bed guides from chips and dirt. Technological equipment For the implementation of complex technological operations, the PR622F4 machine is supplied with a specialized kit: Hanging faceplate, Hollow spindle extension, Special clamping devices for fixing automatic coupling housings and side frames of bogies, Sets of cutting tools and mandrels for specific parts
