Our best estimate for a 5-axis machining center in this class — not a quote from Mitsui Seiki. Configuration moves it a long way.

Overview

The Mitsui Seiki Vertex 100 is listed as a 5-axis machining center with 1,000 x 700 x 500 mm (39.4 x 27.6 x 19.7 in) of travel, an 800 mm (31.5 in) table and direct-drive A and C axes. Mitsui Seiki's current lineup does not show this model, so it may be an older one, and the listed figures should be treated as a checklist for the machine in front of you.

Read the proportions first. The table is 800 mm (31.5 in) across but the load limit is 500 kg (1,102 lb), so this is a machine for large, comparatively light parts and not for dense blocks. X travel of 1,000 mm (39.4 in) is twice the 500 mm (19.7 in) of Z, which suits wide, shallow work.

Both rotary axes are direct-drive. A swings ±120 degrees and C turns a continuous 360 degrees. Direct drive puts no gear train between motor and table, which is why it is favoured for simultaneous contouring. The control row adds nano-smoothing.

The spindle is an HSK-A63 unit at 20,000 rpm with 30 kW (40 HP) continuous. Together with 50 m/min (1,969 ipm) rapids, the listed figures describe a machine aimed at high-speed finishing; no torque row is given. Positioning accuracy is listed at ±2.0 µm and repeatability at ±1.0 µm. The magazine holds 60 tools, with 90 optional, and the machine weighs 16,000 kg (35,274 lb).

Strengths & Limitations

Strengths

Direct-drive A and C axes, with ±120 degrees of A travel and a continuous 360 degrees on C
20,000 rpm HSK-A63 spindle with 30 kW (40 HP) continuous
50 m/min (1,969 ipm) rapid traverse
Listed positioning accuracy of ±2.0 µm and repeatability of ±1.0 µm
A magazine of 60 tools, with 90 optional

Limitations

Table load is 500 kg (1,102 lb) on an 800 mm (31.5 in) table, which rules out dense, heavy workpieces
Z travel is 500 mm (19.7 in), half the X travel, so tall parts and long tools compete for the same stroke
No spindle torque figure is listed, so roughing capacity cannot be read from the table
At 16,000 kg (35,274 lb) the machine needs a prepared foundation

Best For

Large, light 5-axis parts up to the 500 kg (1,102 lb) table load Simultaneous contouring on direct-drive A and C axes High-speed finishing at 20,000 rpm with HSK-A63 tooling Wide, shallow parts within 1,000 x 700 x 500 mm (39.4 x 27.6 x 19.7 in)

Frequently Asked Questions

01 What are the travels and table size of the Vertex 100?

The listed travels are 1,000 mm (39.4 in) in X, 700 mm (27.6 in) in Y and 500 mm (19.7 in) in Z. The table is 800 mm (31.5 in) in diameter with a maximum load of 500 kg (1,102 lb).

02 How are the rotary axes driven on the Vertex 100?

Both A and C are listed as direct-drive. The A axis range is ±120 degrees and the C axis is continuous through 360 degrees. Direct drive has no gear train between motor and axis, which matters for smooth simultaneous 5-axis motion.

03 What spindle does the Vertex 100 have?

The listed spindle runs at 20,000 rpm with an HSK-A63 taper and a 30 kW (40 HP) continuous motor. No torque figure is given, so judge it as a high-speed spindle unless the machine's own data shows otherwise.

04 How accurate is the Vertex 100?

The listed figures give ±2.0 µm positioning accuracy and ±1.0 µm repeatability. On a used machine, ask for a recent laser or ballbar check to see what the individual machine holds today.
