CMZ has reached a significant manufacturing milestone with the sale of its 3000th TA series lathe, underlining the enduring popularity of the slant-bed turning centre among manufacturers seeking precision, reliability and long-term performance.

Introduced more than 20 years ago, the TA Series has earned a strong reputation in demanding production environments by combining robust construction with high machining accuracy and productivity. The range is available with three Z-axis travel options of 400, 600 and 1100 mm, providing the flexibility to suit a wide variety of turning applications.

A defining feature of the TA series is its prismatic bed, which is stabilised, machined and ground in a single set up at CMZ’s manufacturing facilities. Each machine is hand-scraped during assembly to optimise slideway performance, while direct metal-to-metal contact eliminates the need for Turcite, helping maintain long-term geometric accuracy and extending service life.

All models are equipped with an oil-cooled integrated motor turret delivering 75 Nm of torque, 11 kW of power and speeds up to 12,000 rpm. A three-curvic coupling design enables tool changes in just 0.2 seconds while improving thermal stability. Oil-cooled integrated spindles, free from belts and pulleys, further enhance accuracy, surface finish and machining performance by reducing vibration and spindle runout.

The TA series is also fully compatible with CMZ’s GL20 II gantry loader, providing straightforward automation for both short and long production runs.

Manufactured entirely in Europe, the TA series reflects CMZ’s vertically integrated production philosophy, with more than 80% of machine components produced in-house. By maintaining close control over manufacturing and the supply chain, CMZ combines premium components with competitive pricing, delivering machine tools designed to provide reliable performance for more than two decades.More information www.cmz.com

Aerzen has strengthened its machining capability with two further WFL M65 MillTurn centres, creating a highly automated manufacturing cell that is improving productivity, process reliability and ergonomics at its headquarters in Lower Saxony, Germany.

The family-owned manufacturer, which develops blowers and compressors for industries ranging from water treatment and food processing to chemical and process engineering, now operates 10 WFL M65 MillTurn machines, which combine turning and milling capabilities in a single platform. The latest investment integrates two turn-mill centres with an ABB loading robot, Kardex storage system and fully digital production workflow.

The automated cell is primarily used to manufacture rotary lobe blower rotors, processing materials including C45 steel and EN-GJS-500-7 cast iron. According to Tobias Krebs, team leader for mechanical applications, machining these components presents significant challenges due to interrupted cuts and variations in material hardness. To maintain accuracy and stability, the machines are equipped with 55 kW spindles, enabling complete machining in a single set up while consistently achieving machining tolerances of 0.02 mm.

The new cell also links directly with Aerzen’s ERP, tool management and CADCAM systems, allowing production orders, tooling and machine programs to be managed automatically. Once an operator releases a job, the robot retrieves raw components directly from standard delivery pallets using bin-picking technology before loading the machines without manual intervention.

Although automatic part positioning adds slightly to machining time, eliminating manual loading delays has significantly increased overall efficiency. The automation also reduces physical handling of heavy components weighing several hundred kilograms, improving workplace ergonomics and supporting unattended production.

Having relied on WFL technology for almost 20 years, Aerzen cites the machines’ reliability, complete-machining capability and responsive after-sales support among the reasons for its continued investment.

LTS Maskin, the exclusive Norwegian distributor for Colchester Machine Tool Solutions, has overseen the installation of a Harrison V460 variable-speed centre lathe on the Oseberg C offshore platform in the North Sea, supporting critical maintenance operations in one of the world’s most demanding engineering environments.

Operated by Equinor, the Oseberg C Platform required a robust and accurate machine tool capable of delivering reliable machining performance under challenging offshore conditions. LTS Maskin recommended the Harrison V460, recognising its combination of precision, durability and compact design as ideally suited to the application.

The Harrison V460 features a variable-speed drive for smooth, accurate cutting across a wide range of materials commonly encountered in offshore engineering. Its heavy-duty construction provides the rigidity and reliability needed for long-term operation in harsh marine environments, while high levels of machining accuracy and repeatability ensure critical maintenance work can be completed to demanding tolerances.

Ease of operation was another important consideration. The machine’s intuitive controls enable engineers to carry out machining tasks efficiently, while its compact footprint makes it well suited to offshore installations where workshop space is often limited.

The project demonstrates the close working relationship between Colchester Machine Tool Solutions and LTS Maskin, combining proven machine tool technology with local engineering expertise and customer support. Together, the companies continue to supply machining solutions tailored to the needs of Norwegian industry.

The successful installation on the Oseberg C Platform further strengthens Harrison’s reputation in demanding industrial applications and underlines LTS Maskin’s commitment to supporting customers across the offshore, manufacturing and precision engineering sectors with reliable, high-performance machine tools.

Okuma has expanded its Multus U series with the launch of the new Multus U1000 and Multus U2000, two compact multi-tasking turn-mill centres designed to deliver high-precision five-axis simultaneous machining while maximising productivity and floor space efficiency.

Developed to meet growing demand for increasingly complex components in sectors such as medical technology, robotics and electric vehicles, the new machines combine turning and milling in a single platform, helping manufacturers reduce set ups, improve accuracy and streamline production.

The Multus U1000 and Multus U2000 feature X/Y/Z travels of 550/220/880 mm, together with B and C axes offering 240° and 360° movement. The U1000 is equipped with a 6-inch chuck and a main spindle speed of up to 6000 rpm, while the U2000 features an 8-inch chuck and spindle speeds up to 5000 rpm. Both machines come as standard with an automatic tool changer for up to 80 tools, with optional magazines accommodating up to 180 tools for high-mix production.

Automation options include integrated loading robots, bar feeders and parts unloaders, enabling manufacturers to increase productivity while minimising manual intervention. A flat-front machine design allows robots to be positioned closer to the machine, reducing the footprint of automated machining cells.

To maintain long-term accuracy, both machines incorporate Okuma’s ‘5-Axis Auto Tuning System’, which compensates automatically for wear and geometric deviations. Additional technologies include the Thermo-Friendly Concept for thermal stability, the Collision Avoidance System for enhanced process security and optional AI-based machine condition monitoring.

Despite their capability, both machines occupy just 8.2 m² of floor space, making them the most compact models in the Multus U range and well suited to manufacturers where production space is at a premium.
