How much does the TOS Kuřim FRF 350 cost?
Price estimate
We do not have a price for the TOS Kuřim FRF 350 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 350 is a movable-gantry machining centre with a 3,500 mm (137.8 in) table, Y travel of 4,400 mm (173.2 in) and a column clearance of 4,050 mm (159.4 in). Only the FRF 400 is wider in this series.
At this width the carousel option starts to matter. The workspace row offers a fixed table with a carousel table, and a wide opening between the columns is what lets a large ring or disc swing under the gantry. The catalogue does not publish a plate diameter for the FRF carousel. Its accessories page for horizontal and gantry centres lists circular plate designs with diameters ranging from 2,000 to 5,000 mm and table loads from 15,000 to 100,000 kg for rotary tables in general, which gives the range to ask about.
Height is the constraint to check. Between table and cross-rail there is 2,050 mm (80.7 in), the cross-rail is fixed, and Z travel is 1,500 mm (59.1 in). A carousel table and its chucking take part of that gap before the workpiece does.
The remaining rows are common to the series: X of 4,000 - 24,000 by 1,000 mm (157.5 - 944.9 by 39.4 in), feeds of 1 - 20,000 mm/min with 1 - 30,000 mm/min in brackets, spindle speeds of 4,000/6,000 rpm and drive power of 30/37/45 kW (40/50/60 hp). Linear roller guideways and axial tool cooling are on the feature list.

Strengths & Limitations
Strengths
- 4,050 mm (159.4 in) between the columns, enough opening for large round parts on a carousel table
- 3,500 mm (137.8 in) table and 4,400 mm (173.2 in) of Y travel
- Multifunctional design with carousel and grinding function, per the maker's feature list
- Axial tool cooling and thermal stabilization of headstock and heads are listed
Limitations
- Still only 2,050 mm (80.7 in) between table and cross-rail, and a carousel table uses part of it
- Carousel plate diameter and speed are not published for the FRF
- The 30/37/45 kW drive row is the same as on the smallest FRF, so the wider machine does not bring more power

Frequently Asked Questions
01
Table width 3,500 mm (137.8 in), Y travel 4,400 mm (173.2 in), Z travel 1,500 mm (59.1 in), 4,050 mm (159.4 in) between columns and 2,050 mm (80.7 in) from table to cross-rail. X is chosen from 4,000 - 24,000 by 1,000 mm (157.5 - 944.9 by 39.4 in).
02
It can. The workspace is listed as a fixed table or a fixed table with a carousel table, and the series is described as a multifunctional design with carousel and grinding function. Diameter, speed and load of the carousel are not in the FRF table and need to be requested.
03
The feed range is printed once for X, Y and Z: 1 - 20,000 mm/min, followed by 1 - 30,000 mm/min in brackets. The catalogue does not say what the bracketed range depends on.
04
The FRF 400 is the same machine made wider: 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. Height, Z, spindle and drive are unchanged, so the FRF 400 is worth it only for the extra width.
