The EM family has been in production since 2003 and continues today. These are current machines, and turret wear on them is a function of utilisation rather than age.

Where this machine is in its life

The EM-2612 MII is a current-generation machine (2014). If yours is showing turret wear, it is not because the machine is old — it is because it has been working. High-utilisation machines reach the same bore wear in a fraction of the calendar time.

On a machine this current, the dominant cost is not the repair. It is the production you lose while it is out, which is why the work is done on your floor in days rather than the machine going anywhere.

How a EM-2612 MII turret wears

At 22 tons, the EM-2612 MII is a lighter, faster machine, and its turret wear pattern reflects that. wear accumulates through sheer cycle volume rather than force per hit. A high-throughput shop can put more hits through a 22-ton machine in a year than a heavy press sees in five.

With 49 stations, a EM-2612 MII turret usually shows wear concentrated in the positions running the most common tooling. Sleeving does not have to be all-or-nothing — the worn stations are done and the rest are left as they are.

The tell is always the same: the fault stays with the station rather than following the tool. Move a tool that is producing bad parts to another station — if it runs clean there, the bore is worn, and new tooling will not change that. See holes out of round or burring on punched parts for the full diagnosis.

What sleeving a EM-2612 MII involves

Each worn bore is machined to a precise oversize and a hardened USA-made steel sleeve is pressed in with an interference fit, restoring the station to Amada factory tolerance — typically within 0.0002″. Engineers travel to you; the EM-2612 MII never ships. 2–3 days of downtime, typically $8,000–$25,000 depending on scope. After the first install your own maintenance staff can replace sleeves in future.

Set against $100,000–$500,000+ for a replacement machine — see sleeve or replace, including where replacing genuinely wins.

2 A/I + 2 MPT on this machine

The EM-2612 MII carries 2 A/I + 2 MPT. Auto-index stations rotate tooling in 0.01° increments through gears, bearings and a rotary encoder mechanism — all in constant motion, all wearing. Symptoms are angular drift, indexing errors, alarm codes and parts punched off-angle.

TSI rebuilds them completely and calibrates before sign-off, routinely in the same visit as sleeving. Auto-index refurbishment · diagnosing angle errors.

Is the EM-2612 MII a thick or thin turret machine?

The EM-2612 MII is a thick turret machine. Thick and thin describe the turret, not automatically the tooling — the two are quoted separately, and a machine has to be identified on both counts before sleeves or tooling are ordered.

Tonnage will not tell you either: several 22-ton Amada machines run thick turrets. If you are not certain what your press carries, send us the model and serial number and we will confirm it. See also thick vs thin turret and how Amada model numbers work.

How the EM-2612 MII compares

Multi-Purpose Tool stations — that is what sets this machine apart on the spec sheet.

These machines are easy to mix up, and the difference matters when you are quoting a turret job. Against the other EM models we cover:

• Amada EMK-3610NT — tonnage 33 ton, stations 58, control AMNC-F PC.
• Amada EMK-3612 M2 — tonnage 33 ton, stations 55/58 King, control AMNC 3i.
• Amada EMK-3510NT — tonnage 33 ton, stations 58, auto-index 4 A/I.
• Amada EMZ-3610NT — tonnage 33 ton, stations 45-70, auto-index 2/4 A/I.
• Amada EM-2510 — stations 45, auto-index 2 A/I, control Fanuc 18i.
• Amada EM 3612 ZRTe — tonnage 33 ton, stations ATC: 300, control AMNC 3i.
• Amada EMZ-3510NT — tonnage 33 ton, stations 45-70, auto-index 2/4 A/I.
• Amada EMK-3510 M2 — tonnage 33 ton, stations 58 King, control AMNC 3i.
• Amada EM-2510NT — stations 45/58, auto-index 2/4 A/I, control Fanuc AMNC NT.
• Amada EM-2510 MII — stations 45, auto-index 4 A/I, era 2005.
• Amada EML-3610NT — tonnage 33 ton, stations 58, control Fanuc AMNC NT.
• Amada EMLK-3610NT — tonnage 33 ton, stations 58 King, control AMNC NT.
• Amada ELMK-3610NT — tonnage 33 ton, stations 58, control AMNC NT.

Sleeving is the same process across all of them. What changes is scope, and scope follows station count and how hard the machine has been run.

Beyond the turret

The EM-2612 MII runs the Fanuc NT control — current-generation, and not usually a candidate for retrofit. Where a machine of this age needs more than turret work, it is normally wear items: X/Y ball screws, LM guide rails, clutch and brake, work holder clamps, guide keys, springs and collars. All covered under complete overhaul, on-site, in the same visit.
