Our best estimate for a vertical machining centers (vmc) in this class — not a quote from Chiron. Configuration moves it a long way.

Overview

The MILL 800 is listed as a vertical moving-column machining center with 800 × 630 × 550 mm (31.5 × 24.8 × 21.7 in) of travel, a spindle of up to 20,000 rpm and a magazine of up to 60 tools. On a moving-column machine the workpiece stays still while the column carries the spindle through all three axes, so a heavy part does not slow the axes down.

The listed part limits are approximate: a workpiece diameter of about 900 mm (35.4 in) and a weight of about 600 kg (1,323 lb). That diameter is larger than the 800 mm X travel and well beyond the 630 mm Y travel. A part of that size can be loaded, but the spindle cannot reach all of it in one clamping.

HSK-A63 is the listed spindle interface, with HSK-A100 as an option. The 20,000 rpm figure is an upper limit, and the table does not say which interface it belongs to. No power or torque is given for either. The control row names a Siemens SINUMERIK 840D sl. Rapid rates, table dimensions and machine weight are absent, so confirm those, and the figures above, on a quotation.

Strengths & Limitations

Strengths

Travels of 800 × 630 × 550 mm (31.5 × 24.8 × 21.7 in)
Listed workpiece weight of approx. 600 kg (1,323 lb) on a moving-column layout
Spindle speed of up to 20,000 rpm, with HSK-A63 listed and HSK-A100 optional
Magazine capacity of up to 60 tools

Limitations

No spindle power or torque among the listed figures
The approx. 900 mm (35.4 in) workpiece diameter exceeds the 800 mm X and 630 mm Y travels, so the full diameter cannot be machined in one clamping
Rapid traverse, table size and machine weight are not listed

Best For

Prismatic parts within 800 × 630 × 550 mm of travel Workpieces up to approx. 600 kg (1,323 lb) High-speed milling at up to 20,000 rpm

Frequently Asked Questions

01 What are the travels of the MILL 800?

The listed travels are 800 mm (31.5 in) in X, 630 mm (24.8 in) in Y and 550 mm (21.7 in) in Z. The machine design is given as a vertical moving column, which means the travel belongs to the column and spindle and the part does not move.

02 How large and heavy a workpiece is listed?

Approx. 900 mm (35.4 in) in diameter and approx. 600 kg (1,323 lb). Both values are approximate. The diameter is greater than the X and Y travels, so read it as the largest part that can be set up, not the largest area the spindle can cover.

03 Which spindle interfaces are listed for the MILL 800?

HSK-A63, with HSK-A100 as an option. Spindle speed is given as up to 20,000 rpm without saying which interface that applies to. Power and torque are not listed, so ask for both for each interface before deciding.

04 How many tools does the MILL 800 hold?

The listed capacity is up to 60 tools. That is an upper limit, and a particular machine may have a smaller magazine. Limits on tool diameter, length and weight are not listed and are likely to differ between HSK-A63 and the optional HSK-A100.
