Next-generation hybrid and electric press brakes are lean, green production machines that provide clean, quiet and accurate operation, while lending support to a shop's bottom line. Traditional, hydraulic press brakes use gear pumps to pressurize lines that deliver oil to pistons. While the pumps prove fairly reliable, they have some disadvantages. For starters, they continuously draw power even when the press brake sits idle. They also are noisy and can cause machine vibration. Worst of all: During production, temperature changes to the hydraulic oil can cause perceptible shifts in the ram, interfering with the ability to meet tight production specifications.
