Half a century of Wohlhaupter’s MultiBore

Allied Machine and Engineering, a manufacturer of hole-making and finishing cutting tools for the metal-cutting industry, is celebrating 50 years of Wohlhaupter’s MultiBore, the world’s first modular boring system. Making headlines in 1973, Allied Machine says that Wohlhaupter’s MultiBore was the first of its kind that allowed users to change boring tools directly at the spindle. While still a best-seller 50 years later, MultiBore now has applications in a much wider range of machining operations.

Until the early 1970s, machine shops used universal facing and boring heads for rough and fine boring. These boring heads had an integrated shank designed specifically for the machine spindle of the corresponding machine manufacturer. However, every machine manufacturer had its own facing and boring heads, even if some of these came from the same manufacturer, in many cases Wohlhaupter. There were no standardised spindle connection points, so users required their own tools for each machine type.

This situation ultimately created demand for universally applicable modular tools. Instead of a one-piece boring head, it made sense to design tools modularly to fit on all machine tools (with different basic holders), while also offering the capability for individual assembly into complete tools adapted to the workpiece. Wohlhaupter implemented this idea with MultiBore and presented the new product for the first time at the Hannover Trade Fair in 1973. Renowned machine manufacturers quickly decided to supply their machining centres with these new tools, marking the beginning of Wohlhaupter’s success story.

Today, MultiBore comes in a complete diameter range of 0.4 to 3255 mm. MultiBore boring tools fit directly into the master shanks, or users can take advantage of intermediate modules to create full assemblies adaptable to the workpiece and fixtures.

ITC unveils Widia seven-flute milling line

The Widia VariMill range of solid-carbide end mills, available in the UK from Industrial Tooling Corporation (ITC), is seeing yet another evolution with the arrival of the new high-performance machining line of VariMill Chip Splitter end mills.

Suitable for cutting materials in ISO groups P, M, K, S and H, the new series is a high-performance tool that ITC says delivers exceptional material removal rates. The Chip Splitter series is for high chip control in dynamic milling, ramping, helical interpolating and side milling at high speeds and feed rates. This capability enables the tool to run with a longer axial depth of cut while diving into deep pockets in high-temperature alloys, steel and stainless steel. The Chip Splitter series is available as a five- or seven-flute variant with Widia’s WP15PE and WS15PE carbide grades to accommodate the machining of various materials.

Widia’s VariMill Chip Splitter offers features that improve chip evacuation by breaking the chips into small segments. This simplifies swarf removal from the work area and significantly improves cutting speeds and feeds when processing small pockets up to 5xD, or when machining at full depth of cut.

The seven-flute end mills are available with a straight or Weldon shank in 3xD or 5xD variants. Straight-shank 3xD end mills are available in 10, 12 and 16mm diameters with the Weldon shank designation also offering a 20 mm diameter variant. The 3xD tools have a flute length from 32 to 50mm with an overall length of 80 to 110 mm. Similarly, the 5xD plain shank variant is available from 10 to 16mm diameter with the Weldon shank also offering a 20mm diameter variant.

Enhancing the UK’slaunch capability

Skyrora and Spirit AeroSystems are announcing a new collaboration on orbital launch capability. UK-based launch-vehicle manufacturer Skyrora is developing an agile, end-to-end launch service to provide access to space for small satellites globally. Having conducted a test launch of the suborbital Skylark L vehicle in October 2022 as part of the company’s incremental learning approach, Skyrora is well on track to become the first UK company to vertically launch satellites from the UK, expecting to conduct up to 16 launches per year once at scale.

Spirit’s presence in the UK space sector is growing. Its broad offering of adaptive manufacturing and testing solutions in metallics and composites, at both its Scotland and Northern Ireland facilities, brings significant industrial capacity to Skyrora’s launch proposition. Leveraging Spirit’s aero-structures expertise, the companies will explore opportunities to transition Skyrora’s orbital launch vehicles from development to full-scale production.
