ĆKD Blansko

The ČKD Blansko Strojírny, a. s. company ranks among the engineering companies with a rich historical tradition. The beginnings of the engineering production in the place of the present company go back to 1689. The present name of the ČKD company dates from 1927. Besides water turbines, the main long-term assortment of the ČKD Blansko Strojírny company, a. s. includes especially heavy-duty vertical lathes. They are exploited by the company itself for the production of rotation parts of water turbines, which considerably contributes to the operation trials of their technological parameters and capabilities, their reliability, and to the collection of experience and knowledge serving for their future development. Since April 1994, the ČKD Blansko Strojírny, a. s. company holds the quality certificate ISO 9001.

The production programme of heavy-duty vertical lathes of the ČKD Blansko Strojírny, a. s. company includes:

Single-column type SK1: designed for the machining of parts within the maximum diameter range of 3,200 - 16,000 mm, within the maximum height range of 2,500 - 6,500 mm, and within the maximum weight range of 50 - 450 t.

Double-column type SKD: designed for the machining of parts within the maximum diameter range of 3,500 - 6,500 mm, within the maximum height range of 2,500 - 4,000 mm, and within the maximum weight range of 50 - 120 t.

Dependíng on their equipment, single-column and double-column types of vertical lathes permit:
in the turníng mode
- turning the frontal, cylindrical, conical and general rotation ínner and outer surłaces
- turníng the ínner and outer threads on the cylindrícal and conical surfaces, wíth constant and varíable lead
- frontal and perípheral grinding of frontal and cylindrícal, ínner and outer surfaces machínes equipped wíth grinding attachment
- dríllíng and boring openìngs in the axís and

Síngle-column types
desígned with movable column and cross rail, rail head and side head optional extras . They permit to turn pieces within large scope of diameters with the most advantageous position of column permitting to exploit the side head better. These types are convenient especially for turning the annular pieces with large outside diameter that do not require machining of the centre.
