The invention provides an adjustable industrial buffer. The adjustable industrial buffer comprises a shell, a buffer device, a fixer and an adjusting knob; the buffer device and the fixer are arranged in the shell from bottom to top; the bottom of the buffer is connected with the adjusting knob; the top of the fixer is connected with the to of the shell through a fixed cover plate; a piston rod capable of sliding along the fixer is arranged in the fixer; the top end of the piston rod is connected with a pressing head; the bottom end of the piston rod is connected with a piston; an oil storage chamber is formed between the fixer and the inner wall of the shell; and the inner wall of the bottom end of the shell is connected with the buffer device through a sealing rubber ring. The adjustable industrial buffer realizes continuous adjustable precise buffer, realizes linear change of the throttling area, can be applied to more precise machining machinery, provides the most proper buffer strength, and guarantees the machining precision and the equipment durability and reliability.
