How much does the TOS Kuřim SKJ 80 cost?
Price estimate
We do not have a price for the TOS Kuřim SKJ 80 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 SKJ 80 turns the largest parts in the maker's catalogue: a maximum machining diameter of 16,000 mm (629.9 in) and a workpiece weight of 320,000 kg (705,467 lb). Both match the series headline claims of workpiece diameter up to 16 m and tables for loads up to 320 tons.
Everything on this size is scaled up from the two smaller models. The clamping plate is 8,000 mm (315.0 in). The column travels 4,000 mm (157.5 in), which is how the tool gets from the plate out to an eight-metre radius. X travel is 5,000 mm (196.9 in). The ram grows to 450 x 450 mm (17.7 x 17.7 in) and extends 3,200/3,600 mm (126.0/141.7 in), and the cutting force rises to 125 kN.
Vertically, machining height is 5,000/6,300 mm (196.9/248.0 in) and the cross-rail strokes 3,800/4,800 mm (149.6/189.0 in). The plate turns at 25 rpm. That sounds slow until the diameter is taken into account; at the rim of a sixteen-metre part the cutting speed is ample for carbide in steel.
Guideways on X and Z are sliding, and sliding guideways are the only kind on the SKJ feature list. The list also names castings for the essential parts, a modular design, milling and grinding function, and automatic exchange of tool holders and milling heads. A machine of this size is a building project as much as a purchase. The catalogue is silent on foundation, crane capacity and installed power, and each of those needs an answer before the order.

Strengths & Limitations
Strengths
- Machining diameter up to 16,000 mm (629.9 in)
- Workpiece weight of 320,000 kg (705,467 lb)
- 450 x 450 mm (17.7 x 17.7 in) ram with a cutting force of 125 kN
- Column travel of 4,000 mm (157.5 in) and X travel of 5,000 mm (196.9 in)
- Machining height of 5,000/6,300 mm (196.9/248.0 in)
Limitations
- Plate speed of 25 rpm, the lowest in the SKJ table
- The 8,000 mm (315.0 in) plate is half the maximum machining diameter, so the largest parts overhang it
- Sliding guideways on X and Z; hydrostatic ways appear only on the SKD-E and SKDY-E
- No foundation, power or crane data in the catalogue

Frequently Asked Questions
01
16,000 mm (629.9 in), according to the max. machining diameter row; the feature list puts it as workpiece diameter up to 16 m. The clamping plate itself is 8,000 mm (315.0 in), and the movable column travels 4,000 mm (157.5 in) to reach the outer radius.
02
320,000 kg (705,467 lb). That is the same top figure as the SKD-E and SKDY-E classes, which reach it on plates up to 8,000 mm as well but stop at a machining diameter of 10,000 mm (393.7 in).
03
The SKJ 63 machines 10,000 mm (393.7 in) and carries 150,000 kg (330,688 lb) at 40 rpm, with a column travel of 2,000 mm (78.7 in). This model has a longer column travel, a larger ram and a higher cutting force, and turns more slowly at 25 rpm.
04
A ram of 450 x 450 mm (17.7 x 17.7 in) cross-section, extending 3,200/3,600 mm (126.0/141.7 in) in Z. The cutting force row gives 125 kN. A ram with a built-in milling spindle is listed as an option for the series.
