Toshiba TSS 30/55C
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 Toshiba TSS 30/55C is
The Toshiba TSS 30/55C is a CNC vertical boring and turning mill — a machine for turning and boring large-diameter, short work on a horizontal rotary table — rings, hubs, casings and flanges too big or too heavy to hang off a horizontal lathe. The manufacturer publishes a max turning diameter of 216.5 in (5,500 mm).
What it is built to do
From the figures the manufacturer publishes, a Toshiba TSS 30/55C suits:
- workpieces up to the published 44,000 lb (20,000 kg), which on a machine this size is usually the binding constraint rather than the travels
A note on the name. Toshiba Machine Co. renamed itself Shibaura Machine Co. on 1 April 2020, so the manufacturer’s own specification for this machine is published under Shibaura Machine even though the machine, the nameplate and the way everyone in the trade refers to it all still say Toshiba.

These are the manufacturer’s figures for this model as currently published. A machine built years ago may differ in control generation and in options, which is exactly why the questions below matter when you sell one.

What fits a Toshiba TSS 30/55C
Each of these follows from a published specification above, which is named beside it.
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.

What years the Toshiba TSS 30/55C was built
Across the units we have tracked, build years run from 1999 to 2012. Observed across 25 marketplaces, not a manufacturer build record. The manufacturer specifies FANUC 31iB Plus, so a unit on an older control is an early one or a retrofit.
Toshiba TSS 30/55C 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 2 units of this exact designation on the market, drawn from 1 source, spanning model years 1999 to 2012. 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 Toshiba TSS 30/55C
The same list whichever side of the deal you are on.
- Control generation. The manufacturer specifies FANUC 31iB Plus for this model. 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.
- The table bearing. On a vertical it carries the whole workpiece, and a tired one is the end of the machine.
- Rail and ram condition, and whether the crossrail still clamps square after it moves.
- The chuck or faceplate, which on a machine this size is a substantial asset of its own.
- 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.
