Price estimate
We do not have a price for the TOS Kuřim FRUF-B 300-800 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
Between the fast A and the heavy C stands the TOS Kuřim FRUF-B 300-800, a movable-gantry, movable-cross-rail machining centre with 60/71 kW (80/95 hp) of drive power and a 4,000 rpm spindle. Y travel spans 5,200 - 10,200 mm (204.7 - 401.6 in), the widest Y range in the catalogue together with the C size.
Ten metres of cross travel changes how the workspace gets used. A machine this wide is seldom filled by one part. More often it is laid out as zones, a rotary or carousel table at one end and clamping plates along the rest, and the gantry serves whichever zone is loaded. The catalogue lists the workspace as optional with rotary tables and clamping plates, and "great workspace variability" is one of the series features.
The cross-rail moves through a W axis of 2,500/3,000 mm (98.4/118.1 in), and clearance from table to cross-rail is 3,500 - 4,000 mm (137.8 - 157.5 in). Z adds 1,500/2,000 mm (59.1/78.7 in) of ram stroke. Columns are 4,000 - 9,000 mm (157.5 - 354.3 in) apart, and X travel is 5,000 - 25,000 by 1,000 mm (196.9 - 984.3 by 39.4 in).
Feeds on X, Y and Z are 1 - 15,000 mm/min, with 1 - 20,000 mm/min in brackets. W moves at 1 - 2,000 mm/min, or 1 - 4,000 mm/min in brackets. Guideways are linear roller or hydrostatic.

Strengths & Limitations
Strengths
- Y travel of 5,200 - 10,200 mm (204.7 - 401.6 in)
- 60/71 kW (80/95 hp) drive power with a 4,000 rpm spindle
- W axis of 2,500/3,000 mm (98.4/118.1 in) on the movable cross-rail
- 3,500 - 4,000 mm (137.8 - 157.5 in) between table and cross-rail
- Great workspace variability, as the maker's feature list puts it
Limitations
- No 6,000 rpm option at this size
- X, Y and Z feeds are 1 - 15,000 mm/min unless the bracketed 1 - 20,000 mm/min applies
- The clearance range under the cross-rail is narrower than the 3,500 - 6,500 mm (137.8 - 255.9 in) of the FRUF-C 300-800
- Machine weight, floor loading and foundation needs are not in the catalogue

Frequently Asked Questions
01
Drive power is listed as 60/71 kW (80/95 hp) and the maximum spindle speed as 4,000 rpm. That places it above the FRUF-A 250-500, which lists 30/37/45 kW (40/50/60 hp), and below the FRUF-C 300-800 at 100/113 kW (134/152 hp).
02
X 5,000 - 25,000 by 1,000 mm (196.9 - 984.3 by 39.4 in), Y 5,200 - 10,200 mm (204.7 - 401.6 in), Z 1,500/2,000 mm (59.1/78.7 in) and W 2,500/3,000 mm (98.4/118.1 in). X, Y and W depend on the configuration ordered.
03
The clearance between the table and the cross-rail is given as 3,500 - 4,000 mm (137.8 - 157.5 in). The cross-rail travels 2,500/3,000 mm (98.4/118.1 in) on W, so it can be lowered for short parts. Height taken by a rotary table or fixture comes out of the clearance.
04
The FRUF feature list reads linear roller or hydrostatic guideways in linear axes, without tying either to a size. On a frame this large it is a point to settle early, since it affects the foundation, the hydraulic services and the feed rates.
