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

Overview

The Chiron Micro5 is a machining center for parts that fit in the palm of a hand: 78 mm of X travel, 56 mm of Y and 50 mm of Z, with a 60,000 rpm spindle on an HSK-EZ15 interface. Everything on the data sheet is scaled to that envelope.

Start with the spindle. Chiron lists 60,000 rpm and a torque of 10,5 Ncm, figures that only make sense for very small cutters. Micro end mills and drills need that speed to reach a usable cutting speed at all, and they need almost no torque. Larger cutters would ask for more than this spindle gives, whatever the magazine can physically hold.

The magazine itself is generous for the size. A tower magazine holds 60 tools, each up to 18 mm in diameter, or 40 mm with the adjacent places empty, and a change takes 3.5 s chip to chip. With travels this short, 60 tools means a full process, from roughing through engraving and deburring, can stay loaded. Rapid traverse is 30 m/min and acceleration 25 m/s² on X, Y and Z.

The Micro5 XL is the step up, listing 170 mm of X, 140 mm of Y and 120 mm of Z, more than double each travel, with an HSK-E25 spindle at 40,000 or 50,000 rpm. If a part or its fixture comes close to the 78 mm by 56 mm area of the Micro5, the XL is the safer fit; if not, the smaller machine has the faster spindle.

Strengths & Limitations

Strengths

60,000 rpm spindle on an HSK-EZ15 interface for micro tools
Tower magazine with 60 tools on a machine with 78 × 56 × 50 mm of travel
25 m/s² acceleration on X, Y and Z
Higher top speed than the Micro5 XL, which is listed at 40,000 or 50,000 rpm

Limitations

Travels of 78 mm, 56 mm and 50 mm rule out anything but very small parts
Spindle torque is listed as 10,5 Ncm, so cutter size is limited by the spindle long before the 18 mm tool diameter limit
A 3.5 s chip-to-chip time adds up on parts that use many of the 60 tools
The sheet rows give no table size, workpiece weight or power figure

Best For

Micro-milling of parts within a 78 × 56 × 50 mm envelope Very small cutters that need 60,000 rpm Complete processes with up to 60 tools loaded Fine detail work where 25 m/s² acceleration keeps short moves quick

Frequently Asked Questions

01 How big a part can the Micro5 machine?

The travels are 78 mm in X, 56 mm in Y and 50 mm in Z, so the part, its fixture and the tool stick-out all have to fit inside that space. The sheet rows shown here give no table size or load. For larger work the Micro5 XL lists 170 mm, 140 mm and 120 mm.

02 What spindle does the Micro5 have?

A single spindle with a maximum speed of 60,000 rpm, a listed torque of 10,5 Ncm and an HSK-EZ15 tool interface. The combination is meant for micro tools: very high speed, very little torque. No power rating appears in the rows.

03 How many tools does the Micro5 hold?

The tower magazine holds 60 tools. Maximum tool diameter is 18 mm, or 40 mm when the adjacent places are left empty. Chip-to-chip time is 3.5 s. The rows give no maximum tool length or weight, which should be confirmed for the longest tool in the process.

04 What is the difference between the Micro5 and the Micro5 XL?

Size and spindle. The Micro5 XL has travels of 170 × 140 × 120 mm, an HSK-E25 spindle at 40,000 or 50,000 rpm with 1.8 Nm, and a magazine of 60 or 100 tools. The Micro5 has 78 × 56 × 50 mm, HSK-EZ15, 60,000 rpm and 60 tools.

05 How fast are the axes of the Micro5?

Rapid traverse is 30 m/min and acceleration 25 m/s² on X, Y and Z. Over a 78 mm stroke an axis spends most of a move speeding up and slowing down, so the acceleration figure tells more about cycle time on this machine than the rapid rate does.
