The Best Channel Letter Bender Machine for All 3D Sign Letters

The best Channel Letter Bender machine Model VAM-S6 Plus is upgraded from model VAM-S1 and VAM-S6, it is the real all-in-one multifunctional best channel bender including all the functions and more than the two models above.

Fully automatic adjustment of slotting depth from both knife notch and milling cutter notch. The swing milling cutter blade for double side notching can achieve freely in different angles. Moreover, the bending force, bending height and thickness are perfectly improved, so it is capable of bending channel letter coils of height up to 200mm (8”) and thickness 2.0mm (.080”). No need to change bender software system, therefore, your time greatly saved. It is the best model for big 3D channel letter signs and different styles of aluminum profile letters fabrication.

1. The best channel bender with swing milling cutter blade for double side notching freely in different angles.

2. Fully automatic adjustment of slotting depth for both knife notch and saw blade notch.

3. The material straighten System to avoid the 3D letter coil stuck during processing.

4. The fully servo and ball screw system to make it more stable, more accurate and more powerful.

5. The clamping feeding system and closed loop control system features a high speed feeding without scratch on the 3D letter coils.

6. The double notch blade could be freely changed upon request. For instance, the knife notch for stainless steel, iron and thick flat aluminum, and the milling cutter (saw blade) for aluminum (profiles).

7. The telescopic bending system can greatly reduce the bending scratch. It is capable of making letters with small angles and complex graphics, and the big 3D sign letters as well.

CNC channel letter bender material pre-straightening

Material Straighten System

The multi-axis material straighten system to avoid deformation of the 3D channel letter coil while feeding, thus the coil won’t be stuck in processing. It is free adjustable for different thickness of material.

Circulating Alternating Feeding System

The Alternating Clamping Feeding system, which is designed by two sets of fixture clamping material, it is aim to eliminate the phenomenon of feeding slip. 

It used the servo drive and high quality ball screw, moreover, the Linear guide configuration makes the feeding smooth. In other words, the material deformation can be controlled well. Most importantly, the length encoder and the system composed of a closed loop control system to ensure the finished 3D channel letters and the source file perfectly matched.

Double Slotting System

It is free to change the planer tool (for stainless steel, iron or thicker aluminum) and swing saw blade (for aluminum and profile). The slot knife is double sided with 8 pieces of flutes, it is high strength and low loss with a high speed slotting. 

The aluminum profile adopts a DC motor drive alloy milling cutter blade (saw blade), it is movable and able to slot in both sides of the letter coils with different angles. What’s more, it is equipped with a high quality ball screw and linear guide to ensure the slotting smooth and flat.

Telescopic Bending System

The telescopic bending system can greatly reduce bending scratch which is able to make 3D channel letters with small angles and the big 3D signs as well. 

The bending parts adopts the servo drive control, so through the adjustment of servo linear, the rigidity and the torque, even the bending radius and the speed are in perfect control. In conclusion, the finished 3D channel letters match accurately with the laser cutting machines, CNC router table or the engraving machines.

Self-developed Software System

The independent channel letter bending software 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 English interface of bender software is simple and user friendly, easy to learn and operate.
