UM-40ACNC - 2-ROLL CNC THREAD ROLLING MACHINE
*Both shafts are driven by servo motors which are able to change rolling direction and speed during thread rolling progress.
*The feeding of right roller is driven by servo motor, the feeding and stay time can be divided for several stages. It is good for extend the roller life and prevent the deform of work piece.
*The conversational program is easier to operate, adjustment, and input the thread roll data.
*CNC thread rolling machines are the choice for larger pitches & deeper depth work pieces.
*The machine bases are FC-25 casting steel.
