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-2510NT is a current-generation machine (2006-present). 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 an EM-2510NT turret wears

At 22 tons, the EM-2510NT is a lighter, faster machine, and its turret wear pattern reflects that. Running at 350 hpm 1"; 900 hpm marking, 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 45/58 stations, work is spread across a wide turret, which is why wear on these machines is so rarely uniform. In practice a handful of stations carry the common tools and wear out well ahead of the rest. Most EM-2510NT jobs are partial as a result — the worn stations are sleeved and the sound ones are left alone, which keeps both cost and downtime down.

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, burring on punched parts or punches dulling too fast for the full diagnosis.

What sleeving an EM-2510NT involves

Each worn bore is machined to a precise oversize and a hardened USA-made steel sleeve is installed with a precision slip fit and secured with retaining compound, restoring the station to Amada factory tolerance — typically within 0.0002″. Engineers travel to you; the EM-2510NT 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.

Auto-index on this machine

The EM-2510NT carries 4 A/I on the 45-station turret; 2 on the 58. 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-2510NT a thick or thin turret machine?

The EM-2510NT 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.

Turret configurations for the EM-2510NT

The EM-2510NT was not built with one turret. Amada offered more than one layout, so the station count does not follow from the model name — it has to be read off the machine. These are the configurations documented for this model:

A–E are Amada tool-station sizes: A ½″, B 1¼″, C 2″, D 3½″, E 4½″. A blank size column means the station and auto-index totals are confirmed but the factory A–E mix is not — we would rather leave it open than guess it.

Confirm before you quote. Because the EM-2510NT exists in more than one layout, we verify the turret from the serial number or a photograph before pricing any sleeving. If you send us the serial number we will tell you which of the above you have, and how many stations that means. Send us the serial number.

Station layouts documented for the EM-2510NT

The EM-2510NT is documented on 2 different turret layouts — which is exactly why the station count has to be read off the machine instead of assumed from the model number. Both are drawn below, so you can tell at a glance which one you are looking at.

Bore positions, bore sizes and the numbering are read from the Amada factory layout sheet. Stations are grouped, not evenly spaced — that grouping is real, and it is the quickest way to recognise your turret. Follow a link for that turret's full station list.

How the EM-2510NT compares

1.65" stroke; 30 RPM turret; 331 lb max — 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 — stations 58 · tonnage 33 ton · control AMNC-F PC.
• Amada EMK-3612 M2 — stations 55, 58, 67 or 70 · auto-index 4 A/I on the 55 and 58; 2 A/I on the 67 and 70 · tonnage 33 ton.
• Amada EMK-3510NT — stations 58 · auto-index 4 A/I · tonnage 33 ton.
• Amada EMZ-3610NT — stations 45-70 · auto-index 2/4 A/I · tonnage 33 ton.
• Amada EM-2510 — stations 45 · auto-index 4 A/I · tonnage 22 ton.
• Amada EM 3612 ZRTe — stations 32, 36 or 40 · auto-index 4 A/I on the 32-station turret; 2 on the 36 and 40 · tonnage 30 ton.
• Amada EMZ-3510NT — stations 45-70 · auto-index 2/4 A/I · tonnage 33 ton.
• Amada EMK-3510 M2 — stations 55, 58, 67 or 70 · auto-index 4 A/I on the 55 and 58; 2 A/I on the 67 and 70 · tonnage 33 ton.
• Amada EM-2510 MII — stations 44/4AI, 45/4AI, 49/2AI or 58/2AI · auto-index 2 or 4, per configuration · tonnage 22 ton.
• Amada EM-2612 MII — stations 44/4AI, 45/4AI, 49/2AI or 58/2AI · auto-index 2 or 4, per configuration · tonnage 22 ton.
• Amada EML-3610NT — stations 58 · tonnage 33 ton · control Fanuc AMNC NT.
• Amada EMLK-3610NT — stations 58 King · tonnage 33 ton · control AMNC NT.
• Amada EM-3510 ZRTe — stations 32 · auto-index 4 A/I · tonnage 30 ton.
• Amada EM-3612 ZRBe — stations 32 · auto-index 4 A/I · tonnage 30 ton.
• Amada EM-3510ZRB — stations 32, 36 or 40 · auto-index 4 A/I on the 32-station turret; 2 on the 36 and 40 · tonnage 30 ton.

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-2510NT runs the Fanuc AMNC 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.
