TOS Kuřim FRF 200

The TOS Kuřim FRF 200 is the narrowest of five FRF gantry machining centres: a movable gantry on a fixed cross-rail, running over a fixed table 2,000 mm (78.7 in) wide. Y travel is 2,900 mm (114.2 in), Z is 1,500 mm (59.1 in), and X is chosen at order from 4,000 - 24,000 by 1,000 mm (157.5 - 944.9 by 39.4 in).

That combination defines the work. A two-metre table under as much as 24,000 mm of gantry travel is a machine for long, fairly narrow parts: beams, frames, rails and bed sections. The gantry moves and the part stays still, so the length of the workpiece does not add to the floor space the way a travelling table would. The catalogue lists "maximum use of bulit-up space" among the FRF features and says the machine can be installed directly on the load-bearing floor of the hall.

Clearance between the columns is 2,550 mm (100.4 in) and the gap from table to cross-rail is 2,050 mm (80.7 in). The cross-rail is fixed, so that height is what you get; parts and fixtures taller than the gap need a different series. Reach into the part comes from the 1,500 mm Z stroke and from the exchangeable spindle heads the maker lists as accessories.

The spindle row reads 4,000/6,000 rpm and the drive power row 30/37/45 kW (40/50/60 hp), so both are choices rather than fixed figures. Feed is given as 1 - 20,000 mm/min on all three axes, with 1 - 30,000 mm/min in brackets. The workspace is either a plain fixed table or a fixed table with a carousel table let in, which is how the FRF covers turning as well as milling. The next size up, the FRF 250, has a 2,500 mm (98.4 in) table and 3,400 mm (133.9 in) of Y travel on the same Z and the same drive.
