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 15S is a compact five-axis machining center that fits 730 × 400 × 425 mm (28.7 × 15.7 × 16.7 in) of travel and a 280 mm (11.0 in) rotary table into approximately 2.5 m² of floor area. Chiron lists linear direct drives on X, Y and Z and direct drives on the A and C axes, on a mineral cast bed.

The drive layout explains the dynamics. Rapid traverse is 75 m/min (2,953 ipm) on all three linear axes and acceleration is 10 m/s² on each, so the machine gets up to speed inside short moves. The tilt axis and the 360° continuous C axis are direct driven as well, with no gear train between motor and table. Water-cooled drives on all axes and the spindle carry the heat of that duty away from the structure.

Part size is modest. The rotary table takes a workpiece up to 350 mm (13.8 in) in diameter and 150 kg (330 lb). X travel is nearly twice the Y travel, which leaves room to move the spindle well clear of a tilted part.

The spindle is offered at 12,000 - 20,000 rpm with 90 - 180 Nm of maximum torque, on SK-40 or HSK-A63. Tooling is the tight spot: the basket tool changer holds 20 tools, each limited to 65 mm (2.56 in) in diameter, about 220 mm (8.7 in) in length and 2.5 kg (5.5 lb). In exchange the change is quick, at 1.7 sec chip to chip. The control is the Siemens SINUMERIK 840D sl.

Strengths & Limitations

Strengths

Linear direct drives on X, Y and Z with 75 m/min (2,953 ipm) rapids and 10 m/s² acceleration on each axis
Direct-drive tilt axis and 360° continuous direct-drive C axis
1.7 sec chip-to-chip time from the basket tool changer
Approximately 2.5 m² of floor area for a five-axis machine with 730 mm (28.7 in) of X travel
Mineral cast bed with water-cooled drives on all axes and the spindle

Limitations

Only 20 tools, where the FZ 16S chain magazine is listed with 42 – 162
Tool weight is limited to 2.5 kg (5.5 lb) and tool length to about 220 mm (8.7 in)
Workpieces are limited to 350 mm (13.8 in) in diameter and 150 kg (330 lb)
Y travel of 400 mm (15.7 in) is well short of the 565 mm on the FZ 18S

Best For

Small five-axis parts up to 350 mm (13.8 in) in diameter and 150 kg (330 lb) Short-cycle work where 1.7 sec tool changes and 10 m/s² acceleration count Shops with little floor space: approximately 2.5 m² footprint Light tooling up to 2.5 kg (5.5 lb) at 12,000 - 20,000 rpm

Frequently Asked Questions

01 What size part fits on the FZ 15S?

The 280 mm (11.0 in) rotary table carries workpieces up to 350 mm (13.8 in) in diameter and 150 kg (330 lb). Linear travels are 730 mm (28.7 in) in X, 400 mm (15.7 in) in Y and 425 mm (16.7 in) in Z. Tool length, up to about 220 mm (8.7 in), comes out of the Z travel available above the part.

02 Which spindle tapers and speeds are available?

Chiron lists SK-40 or HSK-A63, with maximum speeds of 12,000 - 20,000 rpm and maximum torque of 90 - 180 Nm depending on the spindle. The sheet does not state a power rating. One spindle is fitted; this is a single-spindle machine.

03 What are the tool limits of the basket tool changer?

It holds 20 tools. Maximum tool diameter is 65 mm (2.56 in), or 175 mm (6.9 in) when the adjacent places are empty. Tool length is about 220 mm (8.7 in) and tool weight 2.5 kg (5.5 lb). Chip-to-chip time is 1.7 sec.

04 How does the FZ 15S differ from the FZ 15W?

The FZ 15W has the same 730 mm (28.7 in) X and 400 mm (15.7 in) Y travel but adds an integrated 2-position pallet changer, rated at 150 kg (330 lb) per pallet position. The FZ 15W can also be ordered with a chain magazine for 48 / 64 tools; the FZ 15S table lists the 20-tool basket changer only.

05 What drives and control does the FZ 15S use?

Linear direct drives on X, Y and Z and direct drives on the A and C rotary axes, all water cooled together with the spindle. Rapids are 75 m/min (2,953 ipm) and acceleration is 10 m/s² per linear axis. The control is the Siemens SINUMERIK 840D sl.
