CHM or CMM: Choosing Between EBR METAL's Hydraulic and Motorized Folders
CHM and CMM were developed over time as alternative machines for broadly similar sheet metal bending work, and EBR continues to produce both in response to customer demand. CHM offers the wider range of working lengths and is the model our team recommends more often in general terms. CMM can appear somewhat easier to operate from the customer’s perspective, though CHM is also straightforward to use. Our team can help you compare them for your job.

Construction and Standard Equipment
The CHM is built on a welded steel construction. Standard equipment includes:
– Ancor nitrocarburized hardened segmented blades.
– Joystick control for both clamping and bending.
– Bending-angle setup from a digital unit.
– Manual backgauge, standard on all six models.
Optional Configuration
CHM is also available with an optional NC control. It governs the backgauge, the jaw/beam opening and the bending angle. Talk to our team about whether this configuration suits your part and operating requirements.
CHM Technical Specifications
Capacities below are nominal values for carbon/mild steel at 400 N/mm² material tensile strength. Actual suitability for a given job also depends on material thickness, required bending length, tooling and part geometry.
| Model | Working Length (mm) | Max. Bending Angle | Capacity (mm) | Motor Power (kW) | Width (mm) | Length (mm) | Height (mm) | Approx. Weight (kg) |
|---|---|---|---|---|---|---|---|---|
| CHM 1020 | 1020 | 135° | 4.50 | 4 | 1100 | 1160 | 1260 | 750 |
| CHM 1270 | 1270 | 135° | 4.00 | 4 | 1100 | 1380 | 1260 | 950 |
| CHM 1520 | 1520 | 135° | 3.50 | 4 | 1100 | 1710 | 1260 | 1350 |
| CHM 2020 | 2020 | 135° | 3.00 | 4 | 1100 | 2200 | 1260 | 1750 |
| CHM 2520 | 2520 | 135° | 2.50 | 4 | 1100 | 2730 | 1260 | 2250 |

Parts, Bending Work and Selection
The hardened segmented blades support box-and-pan-style bends, trays and parts with return flanges, wherever the part’s geometry fits within the machine’s capacity and beam opening.
To confirm whether a CHM is the right fit for your job, EBR needs the maximum bending width, the maximum material thickness and, ideally, a technical drawing of the part. A drawing becomes especially important for complex bends, since it lets us check the job against the machine’s capacity, tooling and access.
Manual, motorized and hydraulic folding machines differ in operating method, bending capacity and available working lengths. These differences affect what each machine can process.

Frequently Asked Questions
What is the difference between CHM and CMM?
CHM is hydraulic, while CMM is motor-driven. See the comparison above, or contact us with your job details for a specific recommendation.
What information does EBR need to confirm a CHM is suitable for a job?
The maximum bending width, the maximum material thickness and, especially for complex bends, a technical drawing of the part, so we can check the job against the machine’s capacity, tooling and geometry.
Can the CHM bend box and pan shapes?
Its hardened segmented blades support box-and-pan-style bends and parts with return flanges, within the machine’s capacity and beam opening.
Does the CHM have a motorized or NC backgauge?
Standard equipment is a manual backgauge. An optional NC control is available, covering the backgauge, the jaw/beam opening and the bending angle.
What material does the technical table's capacity apply to?
The listed capacities are nominal values for carbon/mild steel at 400 N/mm² material tensile strength. Actual suitability also depends on material thickness, required bending length, tooling and part geometry.
