All-electric servo riveting vs. hydraulic and pneumatic fastener presses
The best press for a fastening cell depends on the joint, required force, process feedback, throughput, and available plant utilities. Compare the drive methods against your actual workpiece before selecting a machine.
How the drive methods differ
| Consideration | Electric servo | Hydraulic / pneumatic |
|---|---|---|
| Force delivery | Motor-driven actuator with programmable motion and force limits. | Fluid or compressed-air circuit; force and control depend on press design. |
| Process data | May provide force and displacement feedback when sensors and controls are fitted. | Instrumentation varies by machine; specify monitoring needs in the quote. |
| Plant utilities | Verify voltage, phases, frequency, and peak demand. | Verify hydraulic power or compressed-air capacity and quality. |
| Maintenance planning | Review actuator, drive, tooling, and sensor service needs. | Review seals, valves, fluid or air systems, and tooling service needs. |
Questions to settle with a sample run
Confirm fastener type and size, sheet material and stack thickness, insertion force, acceptable joint result, cycle time, and access around the part. Ask for a sample-part trial when the joint or tooling is new. Self-piercing rivets (SPR), clinched fasteners, and press-in hardware use different tooling and should be evaluated separately.
Where the DM60-NC fits
The DM60-NC all-electric servo riveting machineis supplier listed at 53 kN maximum force with a 600 mm throat and pressure/displacement feedback. Its brochure lists press-in nuts, studs, and screws up to M8 in carbon steel. The listed electrical supply is 440 V three-phase with 50 Hz motor frequency; confirm compatibility with your facility before ordering. The brochure does not establish SPR capability.
