With larger heights of and distances between centers, the new Varia universal cylindrical grinding machine from Kellenberger is said to be faster and more precise, offering consistently better performance.
For years, the focus of car designers has been the steering gear. The system has been complemented by complex secondary drive systems. Drivers are now clamouring for steering systems with even more precision. In order to meet this demand, the production of associated components also changes – it has to become more efficient and more precise.
Okuma presented a new line of machine tools at the 28th Japan International Machine Tool Fair (November 17- November 22, 2016). The manufacturer’s trade innovations included state-of-the-art 5-axis vertical machining centres and a new type of intelligent multitasking machine. Among the highlights was the introduction of the world’s first multitasking machines capable of milling, turning, and grinding as well as laser-hardening and 3D metal printing.
Additive manufacturing, the creation of 3-D solid objects by using a series of layered materials, allows the production of complex individual components from various materials like plastic, nickel alloys, titanium, stainless steel and precious metals. However, the surface finish of parts created with additive manufacturing frequently does not meet expectations.
