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 FZ 12 S Five Axis is a single-spindle machining center whose data sheet reads like a menu: three tapers (HSK-A40, HSK-A50 or HSK-A63), spindle speeds from 12,000 to 30,000 rpm, torque from 11 to 110 Nm and chain magazines from 24 to 128 tools. The fixed part is the frame, with 550 mm of X travel, 400 mm of Y and 400 mm of Z.

That spread means two machines with this name can be very different tools. The top of the torque range is ten times the bottom. One build could be a 30,000 rpm machine for small cutters, another a 110 Nm machine for steel. Chiron's table does not state which taper carries which speed and torque. As a rule the smaller tapers go with the higher speeds, but pin down the exact spindle before comparing quotes or judging a used machine.

Tool limits are listed once for the model: 85 mm in diameter, 125 mm with the adjacent pockets empty, 250 mm long and 5.0 kg. The 5.0 kg limit is what a heavy holder with a large cutter runs into first. Chip-to-chip time is 2.7 s.

Motion figures are the same whichever spindle is fitted. Rapids are 75 m/min in all three axes, and acceleration rises from 10 m/s² in X to 15 m/s² in Y and 20 m/s² in Z. The table says nothing about rotary axes, workpiece size or spindle power. A sibling, the FZ 12 FX S, is listed with 35 hp (26 kW) and a weight of approx. 24,250 lb (11,000 kg); for more travel the FZ 16S has 660 mm, 680 mm and 500 mm.

Strengths & Limitations

Strengths

Three taper options: HSK-A40, HSK-A50 or HSK-A63
Spindle speeds from 12,000 to 30,000 rpm and torque from 11 to 110 Nm, chosen to suit the work
Chain magazine from 24 to 128 tools
Acceleration of 20 m/s² in Z and 15 m/s² in Y with 75 m/min rapids
Tool diameter up to 125 mm with adjacent pockets empty

Limitations

Y and Z travel are both 400 mm; the FZ 16S lists 680 mm and 500 mm
Tool weight is limited to 5.0 kg and tool length to 250 mm
The table does not say which taper, speed and torque belong together, so the model name alone does not define the spindle
Rotary-axis ranges, workpiece size and table load are not listed

Best For

Shops that want one frame size specified either for speed or for torque Medium-size parts within 550 mm of X and 400 mm of Y Complex parts with long tool lists, up to 128 tools Steel work on the 110 Nm end of the range with HSK-A63

Frequently Asked Questions

01 Which spindle options does the FZ 12 S Five Axis have?

Chiron lists maximum speeds from 12,000 to 30,000 rpm, torque from 11 to 110 Nm and three tapers: HSK-A40, HSK-A50 or HSK-A63. The table gives the ranges only, not the combinations, so the spindle of a particular machine has to be confirmed from its order data.

02 How many tools can the FZ 12 S Five Axis hold?

From 24 to 128 tools in a chain magazine, depending on the version. Each tool can be up to 85 mm in diameter, or 125 mm with adjacent pockets empty, up to 250 mm long and up to 5.0 kg. Tool change is 2.7 s chip to chip.

03 What are the axis travels and speeds of the FZ 12 S Five Axis?

550 mm in X, 400 mm in Y and 400 mm in Z. Rapid traverse is 75 m/min in every axis. Acceleration is 10 m/s² in X, 15 m/s² in Y and 20 m/s² in Z.

04 How does the FZ 12 S Five Axis compare with the FZ 16S?

The FZ 16S is the larger machine: 660 mm of X, 680 mm of Y and 500 mm of Z, with HSK-A63 only, 12,500 to 20,000 rpm, 86 to 208 Nm and 42 to 162 tools. The FZ 12 S Five Axis is smaller but reaches 30,000 rpm and offers the lighter HSK-A40 and HSK-A50 tapers as well.

05 Is the FZ 12 S Five Axis different from the FZ 12S?

Not in the headline figures. The FZ 12S lists the same 550 mm, 400 mm and 400 mm travels, 12,000 to 30,000 rpm, 11 to 110 Nm, the same three tapers and 24 to 128 tools. If the two differ, it is in equipment the table does not show.
