Product Description The main engine plays an foundational role in the whole equipment set, which can be cooperatively applied with handrail embossing unit, end forging unit, arc bending unit, scroll bending unit and twisting unit. The main engine is controlled by computers, which realizes processing accuracy through frequency conversion control, rotation of coder and braking of the electromotor, thus ensuring all produced workpieces to be completely same to each other in specifications. All units of various functions in the main engine are easy to assemble and disassemble, as well as flexible to drive and convenient to adjust.
