How much does the TOS Kuřim SKJ 63 cost?
Price estimate
We do not have a price for the TOS Kuřim SKJ 63 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
At 150,000 kg (330,688 lb) of workpiece weight on a 6,300 mm (248.0 in) clamping plate, the TOS Kuřim SKJ 63 is the middle size of the movable-column SKJ vertical lathes. Its maximum machining diameter is 10,000 mm (393.7 in).
The SKJ 50 reaches the same diameter, so why the bigger plate? Support and mass. A wider plate holds a ten-metre part further out toward its rim, and the table under it is rated for half as much weight again as the upper figure of the smaller machine. The cost is speed. The plate rpm row gives a single figure here, 40 rpm, where the SKJ 50 lists 100 - 50 rpm.
Forty revolutions a minute suits the work, though. At large diameters the surface speed is already high at low rpm, and only features near the centre of the part would want more. If a job combines a big outside diameter with small bores, that is the limit to plan around.
Travels match the smaller model: X 4,000 mm (157.5 in), column travel 2,000 mm (78.7 in), ram extension 2,000/2,500 mm (78.7/98.4 in) and cross-rail stroke 2,000 - 3,500 mm (78.7 - 137.8 in). Machining height is 3,000 - 5,000 mm (118.1 - 196.9 in). The ram is 340 x 340 mm (13.4 x 13.4 in), the cutting force 100 kN, and the X and Z guideways are sliding. Milling heads and tool holders are exchanged automatically.

Frequently Asked Questions
01
Maximum machining diameter 10,000 mm (393.7 in), machining height 3,000 - 5,000 mm (118.1 - 196.9 in) and workpiece weight 150,000 kg (330,688 lb). The clamping plate is 6,300 mm (248.0 in) in diameter.
02
The clamping plate rpm row gives 40 rpm. No range or lower limit is printed for this size. For comparison the SKJ 80 lists 25 rpm on its 8,000 mm (315.0 in) plate.
03
Yes. The series is described as movable column, movable cross-rail, and the table lists a column travel of 2,000 mm (78.7 in). The cross-rail stroke on the W axis is 2,000 - 3,500 mm (78.7 - 137.8 in).
04
The feature list includes a multifunctional machine design with milling and grinding function, a ram with a built-in milling spindle as an option, and automatic exchange of tool holders and milling heads. Spindle speed and power for milling are not in the SKJ table.
