Since the first range of Okuma CNC Double Column Machining Centres were introduced in 1966 they have set the industry benchmark with more than 10,000 units sold to date worldwide, surpassing all competitors with the long-time Okuma cultural ethic and success.

Within the Australian and New Zealand market the first Okuma double column machining centre was delivered to a customer in Christchurch, New Zealand in 1981 and this machine remains in active service. Since that time forty-two (42) have been installed with a record breaking seven (7) being installed and commissioned within the current 2024 year.
Ideally suited to a broad range of industry segments the Okuma Double Column Machining Centres are now extensively used in industries such as rail, heavy transport, mining, hydraulics, industrial machinery, tool & die, gas & fuel, power generation and general engineering, among many others.
Leading specialist engineering supplier, Steelrod Pty Ltd in Queensland has substantially increased its capacity by adding a second high-speed Okuma Double Column Machining Centre (DCMC) to their workshop. Their first Okuma DCMC was an Okuma MCR-BII with a table capacity of 45 ton with the ability to handle jobs as large as 7 x 3 metres.
The latest high speed Okuma DCMC model MCR-A5CII installed in 2024 has auto-loading/unloading attachments for true 5-sided machining in a compact footprint. The solid double column construction ensures greater rigidity and closer tolerances.
“The additional capacity provided by a second Okuma Double Column Machining Centre bolsters our ability to support the wide range of industries we serve, such as rail, mining, wharf infrastructure and construction including bridges,” commented Damian Veneris, Director of Steelrod Pty Ltd.
The latest Okuma Double Column Machining Centre Model MCR-BV just released, is the seventh machine offered in the company’s double column machine line-up.

Charlie Eilbeck of Eilbeck Heavy Machining commented, “We are simply hard core Australians that love to build things. We attribute our success to our philosophy of investing back into our people and our business. The investment in Okuma machines has been a core factor in the recent expansion of our manufacturing facilities. The expansion of our CNC capabilities is one of the key attributes to our ongoing success,” he said.

Designed as a machine for five-face machining applications the MCR-BV is capable of 5-axis contouring as well as 5-sided heavy milling operations. These heavy duty applications are made possible through the machine’s powerful integral motor and spindle, an expanded work envelope and a rigid table that is 30% thicker than previous models. The range of attachment heads are compatible with the machines performance abilities, enabling a wide range of unique part shapes to be created as well as performing many multitasking machine functions.
The MCR-BV machine features a table size of 2,000mm x 4,000mm to 3,000mm x 12,000mm as well as a spindle speed of 6,000 min -1 (a 10,000mm -1 option is also available). The spindles have a motor power of 43 kW and the MCR-BV’s rapid traverse is X:30m/min, Z:15 .min. In addition the machines have a magazine capacity of 50, 80, 100, 120 or 180 tools.
Additional features of the machine include a fast automatic tool changer (ATC) and smaller, faster auto attachment changer (AAC) both of which enable the MCR-BV to increase productivity while performing heavy duty cutting and highly accurate finishing.
Okuma’s advanced design and manufacturing quality results in a very high degree of accuracy over an extended period plus a long product life. In addition advanced green smart and energy-saving technology is used contributing to decarbonising through Thermo-Friendly Concept Premium.
This feature eliminates the need to use electricity to control room temperature as the machine cooling systems manage excess heat and maintain accuracy. Dimensional change over time due to environmental temperature changes are only 16/um (X-axis direction) i.e. less than half of the standard specification of previous models. This unique Okuma concept of adapting to temperature changes contributes to power savings for the entire factory.
Okuma’s ECO Suite Plus enables stable machining accuracy and energy savings. 3D calibration is featured on the machine autonomously maintaining high accuracy over long periods without relying on skilled personnel.

“From installation of our MCR-A5CII through to operation, our experience with Okuma has always been extremely reliable and trouble free,” commented Justin McMillan, McMillan Engineering Group. “McMillan and Okuma are a great union; two great Australian companies investing in their businesses to grow while advancing manufacturing,” he said.

“There is an air of excitement in the Australian and New Zealand markets around the largest machining centres in the Okuma range being installed and when a range of machine tool builders use our Double Column Machining Centres to build their machines, I guess that says it all,” commented Dean McCarroll, Managing Director Okuma Australia and New Zealand.
