STŞ 2250

STŞ 2250 Line Boring Machine: Is practically used quick machine which has been developed for processing all sorts of engine block main bearing and cam shaft bearings. It is offered to the use of all engine reconditioning with its vibration resistant, high quality cast-iron. Workhead body and bar rod bearings, Steel constructed body on which the tension elimination process is applied and ground precision columns which are chrome coated. At the main bearing to be processed, bar rod and support base at various diameters in accordance with the engine size choices have been offered. Once the machine starts the operation, the main workhead is automatically lubricated; the bar rod bearings are lubricated by dripping method during the process. The movement of workhead of body and bar rod bearings to the forward-backward and up-down and centering of the engine block to be processed with bar rod pliers with joint provide an extremely easiness and speed. Having the automatic stop system during the forward-backward movement of the maximum bar rod provides working security. The two different control panels which can work parallel to each other provide a convenience in use during the adjustment and process. Moreover; due to the varying rotation and feed speed chaises, an extremely exact and luminous work surfaces are obtained.
