Okuma premium solutions for complete machining processes

CNC machine tools must always be precise, energy-efficient and cost-effective. They also have to meet the special requirements of the machining processes, especially in highly specialized industries. Okuma’s premium solutions take the cutting performance of its high-performance machines to a new level and enable complete machine processes with advanced technologies.

Turn-Cut, Flat-Tool Grooving and Gear Machining Package

Turn-Cut allows a turning process to be mapped onto Machining Centres or Multitasking Machines. Special tools and long set-up times are not required. Instead, the turning movements are interpolated along the X and Y axes, and the spindle angle is synchronised. This means that the programmed tool path remains constant during machining.

Okuma’s Gear Machining Package is a hardware and software extension for Turning and Milling Centres that simplifies the programming and cutting of gears by selecting the tool type, workpiece data and machining parameters. Multiple spindles are automatically synchronised, reducing machining times. Both hobbing and skiving processes are supported.

Flat-Tool Grooving is a process that produces an airtight groove with the use of grooving steel and without post-processing. The spindle is synchronised with the movement of the X-Y axis. This makes it possible to produce any geometry, even complex shapes.  

Hyper-Surface, Dynamic Tool Load Control and B-Axis Turning

B-axis turning allows curved surfaces to be turned efficiently without changing tools. The X, Y and B axes are all controlled simultaneously to turn curves at the best angle and without offsets.

The Hyper-Surface function is not only important for tool and mould making. It detects changes in programmed shapes and ensures a consistent feed rate. This improves surface quality and reduces machining time.

When machining demanding and difficult-to-cut materials, such as Inconel, the Dynamic Tool Load Control is an advantage. The application measures the concentricity and position of each cutting edge of an insert milling cutter and adjusts the feed rate for each cutting edge individually. This method loads the cutting edges evenly and compensates for concentricity problems. This ensures consistent and reliable machining, extends tool life, reduces downtime and lowers production costs.

Auto Attachment Head Compensation, NC Gage, C-Axis Torque Limit

Auto Attachment Head Compensation is a special solution for Double-Column Milling Machines. After a short set-up time, it automatically sets compensation values for the rotation of the tool head, providing support for efficient and precise machining.

NC Gage enables complex measuring tasks on Turning and Milling Centres. It reduces set-up times and allows the machine to detect and correct geometry errors.

C-Axis Torque Limit allows operators to easily set C-axis zero points without the need for expensive measuring equipment. Mechanical contact with a simple stopper determines the position.

Variable Spindle Speed Threading, Variable Lead Threading and Thread Phase Matching

Variable Spindle Speed Threading allows the feed rate or spindle speed to be adjusted during threading. This minimises vibrations while maintaining ideal cutting conditions for a consistent thread pitch and good flank surface quality. 

Variable Lead Threading prevents the formation of chatter marks by allowing easy programming of variable cutting depths during thread turning. 

Thread Phase Matching locates the thread path for re-tapping by simply positioning the tool with the handwheel.

With these technologies, Okuma once again underlines its role as a single-source supplier, as all machine components are manufactured by Okuma itself. Customised CNC solutions with highly specialised software and hardware allow optimal interaction of all machine components and energy and cost-efficient operation.
