How much does the TOS Kuřim FRF 400 cost?
Price estimate
We do not have a price for the TOS Kuřim FRF 400 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 TOS Kuřim FRF 400 is the widest FRF: a 4,000 mm (157.5 in) table, 4,900 mm (192.9 in) of Y travel and 4,550 mm (179.1 in) between the columns of its movable gantry. It closes the series of five sizes.
Everything that is not width is shared with the smaller machines. Z travel is 1,500 mm (59.1 in). The fixed cross-rail sits 2,050 mm (80.7 in) above the table. The spindle is listed at 4,000/6,000 rpm with 30/37/45 kW (40/50/60 hp) of drive power, and X is ordered from 4,000 - 24,000 by 1,000 mm (157.5 - 944.9 by 39.4 in). So the FRF 400 is a wide, low machine. It suits big flat work far better than tall work.
If the part needs more than the FRF offers, the catalogue points in two directions. For width or height, the FRUN-A 200-500 has a table of 2,000 - 5,000 mm (78.7 - 196.9 in) and at least 2,450 mm under its cross-rail. For a cross-rail that moves, the FRUF-A 250-500 adds a W axis of 2,000/2,500 mm (78.7/98.4 in). Both list linear roller or hydrostatic guideways, where the FRF list names linear roller guideways only.
Feeds are 1 - 20,000 mm/min on X, Y and Z, with 1 - 30,000 mm/min in brackets. The maker lists the FRF as suitable for installation directly on the load-bearing floor of the hall, which is a real saving on a machine this wide. Confirm the floor requirement for the X length you order.

Strengths & Limitations
Strengths
- Widest FRF: 4,000 mm (157.5 in) table, 4,900 mm (192.9 in) Y travel, 4,550 mm (179.1 in) between columns
- X travel up to 24,000 mm in 1,000 mm steps on the same cross-section
- Can be installed directly on the load-bearing floor of the hall, according to the series feature list
- Feed range of 1 - 20,000 mm/min on all three axes, with 1 - 30,000 mm/min in brackets
Limitations
- 2,050 mm (80.7 in) under a fixed cross-rail is low for a machine 4,550 mm (179.1 in) wide between columns
- Z travel of 1,500 mm (59.1 in) is the only stroke; the FRUN-A 200-500 lists 1,500/2,000 mm (59.1/78.7 in)
- Drive power is limited to the 30/37/45 kW row; higher ratings appear only in other series
- Hydrostatic guideways are not on the FRF feature list

Frequently Asked Questions
01
The table is 4,000 mm (157.5 in) wide, Y travel is 4,900 mm (192.9 in) and the columns stand 4,550 mm (179.1 in) apart. These are the largest figures in the FRF table; the catalogue gives no outside dimensions or weight for the machine.
02
The table-to-cross-rail clearance is 2,050 mm (80.7 in) and the cross-rail is fixed. Z travel is 1,500 mm (59.1 in). For taller work the FRUN-A 200-500 lists a clearance of min. 2,450 mm (min. 96.5 in) under its cross-rail.
03
The table lists a maximum spindle speed of 4,000/6,000 rpm and drive power of 30/37/45 kW (40/50/60 hp). The series features add thermal stabilization of the headstock and exchangeable spindle heads, and axial tool cooling. No taper, torque or tool magazine is stated for the model.
04
The maker's feature list says the FRF can be installed directly on the load-bearing floor of the hall. It gives no floor loading or machine weight, so the hall floor has to be checked against the supplier's installation drawing for the chosen X travel.
