In modern sign fabrication, channel letter automation isn’t just a luxury – it’s the key to staying competitive. For sign shops and manufacturers looking to produce high-quality channel letters quickly and profitably, having the right equipment is essential. Computerized Cutters, Inc. offers a tightly integrated lineup of machines, each tailored to a specific part of the channel letter fabrication process. With Computerized Cutters’ machines, a sign shop can make an entire channel letter from start to finish.
This guide explores the roles, features, and advantages of CCI’s flagship machines – the Accu-Bend channel letter benders, Accu-Cut CNC router tables, Accu-Clinch fastening machines, and the Accu-Trim EDGE trim cap machine – and explains how each machine complements one another to form a seamless, start-to-finish channel letter production workflow.
1. The Foundation: Accu-Bend Channel Letter Bending Machines
Primary Function: Bending channel letter coils to form letter returns
Key Actions: Notching, flanging, bending
Relevant Models: Accu-Bend Freedom, Accu-Bend ACE+, Accu-Bend Stingray
The Accu-Bend product line is the cornerstone of automated channel letter manufacturing. These channel letter bending machines transform flat coils into the 3D letter returns that form the sides of channel letters. Available in multiple Accu-Bend models tailored to shop size and material needs, every Accu-Bend machine delivers speed, accuracy, and a major reduction in labor and costs.
- Accu-Bend Freedom: Compact and portable, table-top channel letter bender ideal for small shops or overflow capacity.
- Accu-Bend ACE+: Mid-level powerhouse channel letter benders with options up to .063″ material thicknesses.
- Accu-Bend Stingray: Industrial-grade, high-capacity machine for the full spectrum of letter sizes and styles.
Role in the Workflow: Forms the structural skeleton of the channel letter – the bent letter return that defines its 3D shape.
2. The Precision Cutter: Accu-Cut CNC Router Tables
Primary Function: Cutting channel letter faces, back panels, and sign shapes from flat sheets of material
Key Actions: Routing, engraving, contour cutting
Relevant Model: Accu-Cut XLR8 CNC Router Table
The Accu-Cut XLR8 is engineered specifically for the sign industry. It cuts the materials for your channel letter and is equally adept at carving backs from aluminum, wood, aluminum composite material (ACM), wood, plastics, and more. With powerful stepper motors, 15-20mm linear bearing rails, helical racks and gears, and specialized cutting software, the Accu-Cut XLR8 offers high-speed, high-precision performance.
Role in the Workflow: Cuts the materials and channel letter components that complete the channel letter – ensuring perfect fits and clean edges.
3. The Assembly Expert: Accu-Clinch Metal Fastening Systems
Primary Function: Mechanically fastening letter backs to channel letter returns
Key Actions: Clinching with or without self-piercing rivets
Relevant Models: Accu-Clinch SPR, Accu-Clinch Model 620
Once the channel letter returns and letter backs are produced, they must be joined into a rigid, sealed channel letter can. The Accu-Clinch product line automates this process using either self-piercing rivets, a fast, clean alternative to welding or hand riveting, or a bottom punch and top die to press form two materials together, eliminating the cost of consumables.
- Accu-Clinch SPR (Self-Piercing Rivets): Ideal for attaching aluminum, aluminum composite material (ACM), and Lexan letter backs
- Accu-Clinch 620 (Without Rivets): Compact, versatile clincher that operates at a rate of nearly one clinch-per-second without the need for pre-drilling or rivets. The Model 620 can clinch returns up to 6” deep and has a throat depth 20” wide – perfect for clinching letters up to 40” tall.
Role in the Workflow: Joins the letter return to its aluminum, ACM, or Lexan back panel – turning separate parts into a complete channel letter body.
4. The Finishing Touch: Accu-Trim EDGE Trim Cap Fabrication
Primary Function: Preparing plastic trim cap to fit letter faces
Key Actions: Notching, bending, cutting trim cap material
Relevant Model: Accu-Trim EDGE
Trim cap frames the letter face and gives the channel letter its finished appearance. The Accu-Trim EDGE automates this final step by measuring, nicking, and forming trim cap strips to match the contours of each letter face.
Role in the Workflow: Prepares and shapes the trim cap material that is secured around the face of the channel letter, finishing the front of your channel letter.
How They Work Together
Here’s how a full channel letter production cycle flows when using all four machine types:
- Accu-Cut XLR8 cuts the channel letter face and letter backs from flat sheets of wood, plastic, aluminum, and more.
- Accu-Bend forms the coil into channel letter returns, perfectly shaped to the face perimeter.
- Accu-Clinch fastens the channel letter return to the letter backs, creating a complete letter can.
- Accu-Trim EDGE prepares the trim cap material to match the face, completing the visual design.
Each channel letter automation machine eliminates hours of manual work and ensures repeatable quality, with minimal operator skill required.
