super channel letter bender S40 servo bending motor

Imported Servo Driver System​

The adopt imported brand 1500 watts servo motor and high quality reducer on the super channel letter bender, as well as 3 pieces of servo motor drivers provide large power, consequently to ensure bending strength for processing thicker materials of 3D super letters production.

Circulating Alternating Feeding System

The Alternating Clamping Feeding system, greatly reduced the waste of 3D letter coils. Designed by two sets of fixture clamping material circulating feeding, it is aim to eliminate the phenomenon of feeding slip. 

Servo drive and high quality ball screw, moreover, the Linear guide configuration makes the feeding smooth, in other words, the material deformation can be effectively controlled. Most importantly, the length encoder and the system composed of a Closed-loop control system to ensure the finished channel letters and the source file perfectly matched.

S40 Imported Slotting System​

Imported Slotting System

High quality planer tool with air cooling system specially for large stainless steel, iron and aluminum strips.

CNC lathe knife as a slotting tool of German imported carbide knife, that is to say, it is high strength and low loss, double-sided with 8 pieces of flutes, easy to change, it is time and cost saving. 

Telescopic Bending System

The telescopic bending system is made of nodular cast iron which has good shock absorption and high structural strength. Likewise, the number of parts spliced reduced, therefore, the bending structure never deforms, the positioning accuracy and bending stability effectively improved

The super channel letter bender adopts the servo drive control, so through the adjustment of servo linear, the rigidity and the torque, even the bending radian and the speed are in perfect control. In conclusion, the finished channel letters completely match with the plates cut by laser cutting machines or router and engraving machines..

Self-developed Software System

The self-designed super channel letter bender software system, which is developed based on years of industry experience and customer feedback.

For instance, the professional design of a variety of practical functions for different models, moreover, the software is English interface, it is simple and user friendly, easy to learn and operate.
