The MVL-10HD heavy-duty, ram-type vertical turning lathe (VTL) features a 49" swing and 39" diameter table. Engineered for heavy metal removal rates, its features include full-wrap, arc-shaped column, full-length cross rail, and single-piece saddle for rigidity and cutting performance. The MVL can be configured so that the ram and tool changer accept CAPTO, KM, CAT or other standards, without intermediate tooling blocks, in capacities up to 60 tools.
The MVL’s large cross rail extension allows for easy access to probing part diameters as well as using left and right inserts on each turning tool holder, effectively doubling tooling capacity.
Structural components, including base, column, and cross rail, are made from the highest-quality cast iron, which is stress-relieved for deformation-free performance. Axis ways are of box-type construction, high frequency induction-hardened, and Turcite-B coated for wear resistance.
The column fully curves around the table to maximize mass, rigidity, and dampening and minimizes the distance between the column’s box ways and cutting insert. A single piece, extra-long cast iron saddle supports the ram during cutting, providing additional rigidity.
The horizontal-umbrella rotation style automatic tool changer (ATC) may be replaced with a vertical chain ATC and a side-arm tool-changer, reducing floor space and tool change time.

The news is full of stories about disruptions in the global supply chain that range from microchip shortages slowing automobile production to Christmas toys being stranded on container ships waiting to be unloaded. With the return of domestic air travel reaching pre-pandemic levels, I wondered what long-lasting supply chain issues are having the most impact on aerospace manufacturing. I found some answers in How to survive and revive amid commercial aerospace supplier distress.
I asked for more details from the report’s lead author, Stephane Lagut, posing the question, “What’s emerging as the most critical supply chain challenge in aerospace manufacturing as we look to 2022?”
Lagut, who leads EY global advanced manufacturing & mobility assurance and global aerospace & defense (A&D) sectors replied, “Commercial aero companies have avoided the significant supply disruption we’ve seen impact the automotive and industrial sectors, mostly due to the lower production levels. However, supply chain constraints will hit commercial aerospace as companies begin ramping up production, particularly in narrow-body aircraft. Other challenges include volatile production schedules, labor (vaccine mandates, employee shortage, retention of key talent following deep cuts in 2020), and supplier health, particularly in the lower tiers. These are challenges we’re seeing across the entire advanced manufacturing and mobility industry market.”
Lagut warns of another risk. “Single sourcing is a recurring practice in A&D and is an ongoing bottleneck when disruption hits. There’s a long lead time to source and qualify suppliers to support A&D production.”
Multiple sourcing options significantly minimize the risk of supply disruptions but potentially at a greater unit cost. “It’s worth noting that many aero companies have implemented dual-source programs but with the reduction in build rates in 2020, dual-sourcing wasn’t viable, and many components continue to be single source and may remain single source for some time, given available capacity,” Lagut explains.
The EY report cites as a specific concern the ability of suppliers to fund inventory and working capital necessary for airliner production ramp-up.
“In the past, suppliers have built and held inventory to mitigate supply-chain disruption,” Lagut notes. “Again, operational rigor supported by real-time information on customers’ requirements and lead times will allow best-in-class suppliers to minimize working capital.”
Lagut adds success will require collaboration with the original equipment manufacturers (OEMs) for robust demand-forecasting, and clear orders and contracts to enable funders to support the supply-chain’s inventory and capital expenditures (capex) requirements. “The advantage will lie with suppliers who have scale, operational leverage, and access to funding [to make them] resilient partners.” – Eric
Mill for composite material; Double-column machining center.
CORE D is a 5-axis, optical coordinate measuring machine (CMM) system for measuring small- to medium-sized parts with polished, reflective surfaces and sharp edges, such as turbine blades.
A double-eye sensor ensures good point accessibility and collects reliable data with the light beam axis up to 85° to the surface normal.
The updated CORE D has an automatic cover which closes during the measurement cycle, ensuring perfect optical, thermal, and clean conditions. The unit is shop-hardened, designed to be robot loaded, and occupies a small footprint. It can be calibrated to ISO standards just like a CMM.
MonsterMill FRP solid carbide milling cutter features a special diamond coating for machining carbon-fiber reinforced plastics (CFRP), offering optimum process security, cutting quality, and performance.
Fine chip breakers enhance quiet running and component quality. Large grooves safely clear away dust that may develop, permitting an optimal process temperature to prevent damage such as smearing on the cutting edge. The diamond coating ensures long tool life despite the high abrasiveness of carbon-fiber reinforced plastics. The left-hand helix version offers a push cut for reducing delamination on the top side; the right-hand helix offers a pulling cut for reducing delamination on the underside; the version without a helix produces a neutral cut. Four end cutting edges provide the option of pocket milling by means of angled or circular ramping.
The MCR-BV double-column machining center (DCMC) for 5-face machining, 5-axis contouring, and 5-sided heavy milling offers precision large-part machining in an expanded work envelope. A high torque, high output integral motor and spindle shorten cycle times. The rigid table, 30% thicker than previous models, withstands high cutting forces and the weight of large workpieces. A broad range of attachment heads are compatible with the machine, allowing creation of numerous part shapes and performing many multitasking machining functions.
Additional features include a fast automatic tool changer (ATC) and a smaller, faster auto attachment changer (AAC) which increase productivity while performing heavy cutting or high-accuracy finishing.
Available models include the MCR-BV 25, MCR-BV 30, and MCR-BV 35.

Promoted by CECIMO, the European Association of Machine Tool Industries, and organized by the operational structures of UCIMU-Sistemi Per Produrre, the Italian machine tools, robots, and automation systems manufacturers’ association, EMO Milano 2021 registered more than 60,000 visitors from 91 countries.
At the conclusion of the event, General Commissioner of EMO Milano 2021 Luigi Galdabini said, “The exhibition data confirm the value of the event, considered as the point of reference for the worldwide manufacturing industry of machine tools, robots, and automation systems.”
Exhibition Director Alfredo Mariotti added, “A very large number of exhibitors have expressed their full satisfaction with the results achieved over these 6 exhibition days [which saw] qualified and very motivated visitors.”
Despite the mobility restrictions still in force, EMO Milano confirmed its international character even on this occasion. Foreign exhibitors accounted for 60% of the total, whereas foreign visitors made up 30% of the overall number. The show also attracted the attention of about 400 accredited journalists, of whom 40% were from abroad.
More than 700 companies exhibited in six halls covering 100,000m2 (>1,000,000ft2) of exhibition area. Focal points included EMO Start-Up, which offered a look at new enterprises working on the development of products and projects related to the world of production systems and metalworking, EMO Digital, and EMO Additive Manufacturing.
Exhibitors and organizers gave more than 80 presentations that were attended in-person and through the live streaming service.
The next edition of EMO Milano will take place in October 2027.
