DMG MORI SV-503B
Manufacturer specifications, what it is built to do, the years we have seen them listed, what tooling fits, and what to check on one. MTE also buys them outright.
What the DMG MORI SV-503B is
The DMG MORI SV-503B is a CNC vertical machining center — a machine for milling, drilling and tapping on a fixed table with a vertical spindle — the general-purpose workhorse of most shops. The manufacturer publishes a x-axis travel of 1,020 mm (40.2 in.).
What it is built to do
From the figures the manufacturer publishes, a DMG MORI SV-503B suits:
- work up to the published 1,200 kg (2,640 lb.) table rating
- MAS BT-40 [CAT-40] (SV-503B/40) tooling at up to 10,000 [20,000] min-1 (SV-503B/40)

What fits a DMG MORI SV-503B
Each of these follows from a published specification above, which is named beside it.
40-taper toolholders
This is a 40-taper spindle — the 7:24 steep taper that CAT-40, BT-40 and DIN 69871 (SK-40) holders all share. They share the taper and nothing else that matters: the retention knob and the flange form differ between those standards, so holders do not swap between them without changing pull studs. Knowing which standard a machine was tooled for is worth doing before the holders are packed. The manufacturer names CAT and BT (JIS/MAS 403) for this machine.

50-taper toolholders
This is a 50-taper spindle — the 7:24 steep taper that CAT-50, BT-50 and DIN 69871 (SK-50) holders all share. They share the taper and nothing else that matters: the retention knob and the flange form differ between those standards, so holders do not swap between them without changing pull studs. Knowing which standard a machine was tooled for is worth doing before the holders are packed. The manufacturer names CAT and BT (JIS/MAS 403) for this machine.

What years the DMG MORI SV-503B was built
The 3 units we have seen listed were all 2001. Observed across 25 marketplaces, not a manufacturer build record.
DMG MORI SV-503B machines on the market now
We track listings across 25 used-machinery marketplaces, and every competitor in this market is one of them, so this is a view none of them can produce for themselves. Right now there are 3 units of this exact designation on the market, drawn from 1 source. That is a thin market for this designation, which usually works in a seller’s favor.
We count only listings whose model is spelled as this machine’s own designation. Near spellings that may be a different variant are excluded rather than counted, so this is a floor on what is out there, not a total.
What to check on a DMG MORI SV-503B
The same list whichever side of the deal you are on.
- Control generation. The specification we hold for this model does not name its control. The control is often the single biggest swing on two otherwise identical machines, because it decides which buyers can use it at all.
- Spindle hours and condition. Most controls show run hours on a maintenance or diagnostics screen. It is the first number anyone asks for, so find it before the conversation rather than during it.
- Tooling and accessories. Holders, chucks, steady rests, probing and automation attachments travel with the machine, and they are worth real money separately from it.
- Way covers and the chip auger. Cheap to look at, expensive to ignore — damaged covers are how a way surface gets ruined.
- The tool changer. Count a full carousel change and watch for hesitation.
- A fourth axis or trunnion, if fitted. It is a separate asset and it is counted separately.
- Power and rigging access. How the machine comes out of the building is a real cost, and it is one MTE absorbs, so an accessible machine is worth more to us.
