Hydraulic Press Brakes are designed and developed through years of experience in Sheet Metal Working Machineries. Rajesh Hydraulic Press Brakes are developed by keeping latest technology in mind. Booth cylinders are mounted at back side of Press Brake and are synchronizes for parallelicm between ram & table, by providing mechanical links connected with cylinder. The Heavy duty steel construction frame is so designed to absorb heavy shocks of overload All welding edges are properly machined for weld joint. The electric control panel is fixed on side wall at conveenient place for easy reach of operator. It includes push buttom pendant and foot switch. Standard "V" Block & "V" Punch and manually operated back guage system which is front operated are supplied as standared accessorits. Hydraulic components are of reputed are supplied as standared accessorits. Hydraulic components are of reputed make like Vedekers, Rexroth, Dowty, Yiken, Polyhydron etc.
