Erco Bender 76CNC6V5 CNC Mandrel Tube & Pipe Bender – Walkthrough & Features

The Erco Bender 76CNC6V5 is the maximum-capacity machine in Ercolina’s mandrel bending line: a three-axis CNC automatic mandrel tube bender handling 3″ tube, 2″ Schedule 40 pipe, and – unique in the line – 2″ square tube. It shares the EB65’s control architecture (electric servo feed and rotation, hydraulic CNC bending, ±0.5° precision) with the larger bending head, tailstock, and swing clearance that bigger work demands. The machine feeds, rotates, bends, and extracts automatically from stored programs, so complete multi-bend parts come off finished with no operator repositioning between bends.

Built by CML International in Italy; sold, supported, and serviced in North America by CML USA in Davenport, Iowa.

Built for Production Volume

The 76CNC6V5 is designed for shops where the bender is a production bottleneck: servo-driven feed and rotation position the tube between bends automatically;stored CNC programs (unlimited, via USB) eliminate setup trial and error on repeat orders; and programmable auto mandrel positioning and internal mandrel lubrication keep cycle times and bend quality consistent across long runs. For apart with five bends in three planes, the difference between a semi-automaticmachine and the 76CNC6V5 is measured in both parts per hour and scrap rate.

Key Features

Extended bending head for complex shapes and profiles – space under the work head completely free
Programmable material springback settings for each bend angle (The control automatically compensates for springback – you program the finished angle you need, and the machine overbends to exactly the right degree so the part springs back to your target. No trial bends, no manual adjustment between jobs.)
Programmable carriage movement for tight radii; independent pressure and clamp die adjustment
Standard right hand bending direction
Interactive touch screen with auto and manual operating modes, system diagnostics and multiple language capability

Programmable tailstock interference-zone monitoring eliminates workhead collision
Quick-change tooling system; high capacity with auxiliary hydraulic oil cooling
Hand-held remote bending control, certified Class 3 safety
USB for unlimited program memory storage
Optional software imports IGES/Tekla and DXF files from compatible CAD programs – consult Ercolina for details and pricing
Automatic or manual bend sequencing; tangent or centerline programming; accepts YBC and XYZ input values
Ercolina’s Handrail Professional Series Package (optional)

Applications for the 76CNC6V5

Production exhaust and emissions systems, truck and bus tube assemblies, HVAC and refrigeration circuits, large-diameter handrail and structural stainless, agricultural and off – highway equipment tube, marine exhaust and rails, and any multi-bend part produced in volume where the 3″ capacity and automatic part positioning pay for themselves in throughput. For prototype work at the same 3″capacity, see the semi-automatic TB80.

Frequently Asked Questions

What is the difference between the 76CNC6V5 and the 65CNC3V1?

Capacity. Both are three-axis CNC automatic mandrel benders with the same control system and precision; the 76CNC6V5 handles 3″ tube (vs. 2-1/2″), 2″Schedule 40 pipe (vs. 1-1/2″), and 2″ square tube, which the 65 does not bend. If your parts fit within 2-1/2″ round tube, the 65 does the same quality work at lower investment.

What is the difference between the 76CNC6V5 and the TB80?

Both bend 3″ tube. The TB80 is semi-automatic – ideal for prototypes and small runs at a lower investment. The 76CNC6V5 is fully automatic CNC – built for repeat production where cycle time and consistency drive the economics.

Can one machine bend both tube and pipe?

Yes, with the correct tooling. Tube is measured by outside diameter, pipe by nominal size – tell us what you’re bending and we’ll quote tooling to match.

What support is available in North America?

CML USA in Davenport, Iowa provides installation support, operator training,tooling, spare parts, and factory-trained service for every Ercolina machine.

Which Mandrel Bender Is Right for You?

Ercolina offers four mandrel bending machines. The right one depends on your part size, volume, and how much of your work needs internal mandrel support:

Machine	Capacity	Operation	Best for
030 Mandrel Bender	2-1/2″ tube, 1-1/2″ Sch. 40 pipe, 2″ square	NC semi-automatic, multi-purpose	Mixed shops: standard rotary draw bending plus mandrel capability on one machine
TB80 Mandrel Bender	3″ tube (.125 wall), 2-1/2″ Sch.10 pipe, 2-1/2″ square	NC semi-automatic, dedicated mandrel	Prototypes, R&D, and daily small-lot production needing mandrel-quality bends at lower investment
Erco Bender 65CNC3V1	2-1/2″ tube, 1-1/2″ Sch. 40 pipe	3-axis CNC automatic	Repeatable production of parts to 2-1/2″ with stored programs and automatic cycling
Erco Bender 76CNC6V5	3″ tube, 2″ Sch.40 pipe, 2″ square tube	3-axis CNC automatic	Maximum capacity in the line — production volume, larger parts, and square tube

Not sure? Call CML USA at 563-391-7700 with your tube size, wall thickness, material, bend radius, and annual volume – we’ll recommend the right machine and quote tooling for your exact application.
