How much does the Fidia Linea C4 cost?
Price estimate
We do not have a price for the Fidia Linea C4 that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.
Overview
The Fidia Linea C4 is the mid-length composites gantry in Fidia's Linea range, with 4,500 mm (177 in) of X travel, 3,000 mm (118 in) of Y and 1,200 mm (47 in) of Z. It machines CFRP, honeycomb, multi-layer composites and ceramic matrix composites in 5 continuous axes.
Holding the part is half the job with composites, and the Linea C is offered with three kinds of table: a vacuum table, a standard table with T-slots, or Fidia's Flexible Clamping System, a modular vacuum system intended for rapid retooling. At 4,500 mm (177 in) the working area takes sizeable skins and panels, or two smaller fixtures.
The upper gantry is welded steel, thermally stress-relieved, with roller guides and linear motors on X and Y and a Z axis on double recirculating ball screws. Axis speeds are 60 m/min in X and Y and 30 m/min in Z, and the brochure gives an axis acceleration of 4 m/s². An active thermal compensation system circulates temperature-controlled fluid.
Heads are the M5A (cast iron body) or the M5C (aluminum body). Spindles run at 20,000 1/min or 24,000 1/min on HSK63A with 30 kW or 35 kW, and a 55 kW spindle is listed only for M5A. Dust is collected at the tool and across the chamber, with ATEX Zone 22 filtration. The Linea C3 is the 2,200 mm (86 in) version; the Linea C6 reaches 6,200 mm (244 in).

Strengths & Limitations
Strengths
- Three table options: vacuum table, T-slot table or the Flexible Clamping System
- 4,500 mm (177 in) of X and 3,000 mm (118 in) of Y for large panels
- Active thermal compensation through temperature-controlled fluid
- Axis acceleration of 4 m/s² with linear motors on X and Y
- Programmable suction hood (DRP/M5-R2) positioned by the CNC
Limitations
- Z travel is 1,200 mm (47 in), a little less than the 1,250 mm (49 in) of the Linea S4
- Z runs at 30 m/min on ball screws, while X and Y use linear motors at 60 m/min
- No table load is stated for any of the table options
- HSK63A is the only tool interface listed

Frequently Asked Questions
01
Fidia lists three: a vacuum table, a standard table with T-slots and the Flexible Clamping System, which it describes as a modular solution with vacuum technology designed for rapid retooling. Choose according to how the parts are fixtured today.
02
X and Y slide on roller guides with direct linear motor drives. Z is driven by double recirculating ball screws and synchronous brushless motors. Axis speeds are 60/60/30 m/min and the brochure states an axis acceleration of 4 m/s².
03
The body. M5A heads have a cast iron body and M5C heads an aluminum body. Both are continuous 5-axis heads that take the 30 kW and 35 kW HSK63A spindles at 20,000 1/min or 24,000 1/min; the 55 kW spindles are listed only for M5A.
04
The automatic tool changer has a 24 or 42-position magazine with an automatic protective door and an external opening for loading and unloading tools. The TMS laser tool measurement system is positioned inside the magazine.
