At the MACH exhibition in Birmingham, UK, last month, NCMT showcased a number of Okuma turning centres, including the competitively priced Genos L3000-e-MYW. The display saw the machine fed automatically with shaft-type parts by a Cellro CoMate collaborative robot (cobot). The maximum turning diameter of the Genos L3000-e-MYWis 300 mm while speed of the 22 kW spindle is up to 3800 rpm, all in a compact footprint of 2.5 x 1.9 m.

This 6-tonne turning centre featuring sub-spindle and a 12-station turret with Yaxis and live tooling offers robust construction. An integral spindle motor and rigid guideways make it suitable for the precision machining of many materials, including exotic alloys. User-friendly features include a separate coolant tank for quick servicing, and easy spindle access to speed maintenance and machine set-up, and reduced chip accumulation for less machine downtime during removal.

Okuma’s One-Touch IGF is an option in the OSP control. The One-Touch IGF allows users to describe part geometry including diameter, length, grooves and threads using simple commands, from which the system draws the defined shape and then develops the part program automatically.

Also on the stand was an Okuma MultusU3000 multi-tasking lathe with a 240° swivelling B-axis head and HSK-A63 (optionally Capto C6) 12,000 rpm/22 kW spindle for turning or milling components up to 1500 mm between centres. The tool magazine has 40 stations as standard, but is optionally available with a capacity of 80 tools.

Okuma’s MultusU3000 features Okuma’s own linear scales for high-accuracy positional feedback. Servo motors deliver feed rates of up to 50 m/min in the X and Z axes, and up to 40 m/min in the 250 mm Yaxis. Together with the Caxis on the main spindle, the machine is capable of fully interpolative five-axis (X,Y,Z,B,C) machining of freeform surfaces.
