Automated production of front axles reduces costs per piece

Rába is a large Hungarian supplier of front and rear axles for trucks, tractors and buses. It operates six Univers 6 machines for machining front axles. Satisfied with the good performance of these CNC-machines, Rába has now awarded us the contract for a new machine: the Unitwin6000.

Faster and at lower costs

Rába is operating existing machines in an automated cell that, among others, also includes a measuring and washing unit.
With the new machine they want to produce front axles even faster and at lower cost per piece. Integration into an automated line with measuring and washing machine was an absolute requirement.

Unique solution

The Unitwin6000 offers a solution for significantly reduced cycle times and automation.

The unique twin main spindles can be tilted to machine various kingpin angles. When operated simultaneously, the two spindles cut cycle times dramatically, even down to 4,5 minutes per front axle, depending on the type. Because the spindles tilt and the front axle can be rotated around its length axis, the Unitwin6000 can perform all the required operations: milling, drilling, boring & reaming. It’s a complete machining centre, offering lowest cost per piece and an excellent return on investment.

For Rába the standard design of this machine is adjusted on a few small points making it suitable for integration into an automated line with a measuring and washing machine.

Result

The Unitwin enables Rába to reduce its cycle times with approximately 50%, bringing the cost per component down with more than 30%. Because the machine allows 3D compensation of the operations on the front axle, the quality of the output is higher than ever. Both are an enormous achievement and guarantees a big leap in the customer’s production capabilities and capacity.
