DMG MORI CLX and CMX Machine Tools
The series is divided into the CLX series of basic universal lathes, the CMX V series of basic vertical machining centers and the basic universal milling machines of the CMX U generation.
As a result, DMG MORI’s entire range of technological performance will be opened up for users of CLX and CMX machines. This applies, among other things, to the optional diversity of equipment in spindle technology, for example.
The new basic machines also feature optional Y-axis with its 60 mm travel path for milling operations on the CLX 450 lathes, optional NC rotary table for 4-sided machining in the case of the CMX V or the accelerated rapid traverse and the tool magazine with virtually double the former capacity in the case of the CMX U.
Customers will also be given access to the extensive training and advanced training programs of the DMG MORI Academy. This will entail no restrictions for previous ECOLINE users. On the contrary: the training programs of the DMG MORI Academy will apply 1:1 for existing ECOLINE machines in addition to services and the availability of spare parts.

JOBS Gantry Milling Center
According to the company, the eVer 7 contains 35 percent fewer components compared to similar machines without forgoing the performance of a modern high-speed milling center.
The machine is designed to support high chip removal capacity thanks to the crossbeam structure with multi-triangle section, “MT-frame” and high acceleration and speed (up to 1575 ipm). Customized configurations with fixed or interchangeable heads are also available.
The machine is equipped with the BUSS system for automatic milling heads changing and features a 3-axis power head T3A (5000 rpm, up to 59 hp), suitable for high-removal rate operations. A twist head T3K with a 15000 rpm electrospindle is suitable for semi-finishing and finishing machining.
The eVer 7 is intended for machining large-size aeronautical components and molds and dies requiring both high-power chip removal capacity and high speed finishing operation.

LVD Hydraulic Press Brakes
PPED Series press brakes are suitable for a range of bending jobs. Their rigid construction and servo-controlled hydraulic system are designed to ensure consistent bending results no matter the application. The PPED Series offers three models (PPED-4, PPED 6 and PPED-7) with either two (X, R) or four (X, R, Z1, Z2) standard backgauge axes. According to LVD, a multi-axis backgauge makes the PPED highly versatile and reduces machine setup time across simple to complex bending jobs.
The TOUCH-B touch screen CNC control is designed to minimize operator input and make part programming easy and intuitive. With minimal input, the operator can create designs in 2D and simulate in 3D on the 15" touch screen.
Dimensions are keyed into the controller or the part program is recalled from storage. Users can also work with standard and custom parametric programs for rapid programming. TOUCH-B works with the centralized database and is compatible with CADMAN-JOB and CADMAN-B.
The PPED-7 model in bending lengths from 3 meters and up is equipped with a crowning system as standard. Sheet thickness, bend length, punch radius, die opening and material data are entered into the TOUCH-B control to determine the amount of crowning required to compensate for bed and ram deflection.
LVD’s proprietary design creates a ’crown’ using machined contact wedges that are moved against each other under servo control. The PPED is available in different models from 50 to 320 metric tons, bend lengths from 78” to 157” (2000 to 4000 mm).

Makino Horizontal Machining Center
“The a71nx expands on all of the characteristics that made the original a71 an industry leader,” said David Ward, product marketing manager at Makino. “By expanding machine capacity and integrating cutting-edge technologies, like Vision B.T.S. [broken-tool sensing] and advanced motion controls, Makino has successfully leveraged proven design attributes while enhancing the productive capabilities and overall reliability.”
Designed for the production of midsized cast iron and light alloy parts, the a71nx features a 19.7-inch (500-mm) pallet and added extensions in the X, Y and Z axes, bringing full-axis travels to 31.5 inches, 29.5 inches and 32.7 inches (800 mm, 750 mm and 830 mm), respectively.
The expanded axis travels increase the total machining volume 16 percent compared to the original a71. To accommodate these larger workpieces, the maximum payload was also raised, providing capacity for parts weighing up to 1,000 kg.
The a71nx has also been updated to handle longer and heavier tools. The machine’s standard 60-tool-capacity automatic tool changer (ATC) has six reinforced pockets, yielding a maximum tool length of 18.9 / 22.4 inches (Cat / HSK) and maximum weight of 30 kg.
Additionally, the original a71’s standard worm-gear-driven NC rotary table has been replaced with a direct-drive (DD) motor B-axis table for faster indexing time. The 1-second 90-degree rotation improves production processes with a substantial reduction in non-cutting motion, according to Makino. The DD motor table on the a71nx is also designed to reduce B-axis complexity and eliminate backlash and key component wear for improved reliability.
With options available for CAT-50, BT 50 and HSK-A100 interfaces, the standard 10,000-rpm spindle offers 37kW of power (26kW continuous power) and 512 Nm of torque (305 Nm continuous), suitable for machining a variety of ferrous, hard metal or light alloy workpieces. An optional 20,000-rpm core-cooled spindle is also available.
Similar to other Makino nx-Series horizontal machining centers, the a71nx features tiered or stepped column casting and oversized roller linear guides to boost rigidity, eliminate vibration and extend perishable tool life.
Chip and coolant management has been improved with the addition of a standard hydro-cyclonic filtration system. This system cleans coolant down to a 20 μm level, extending the maintenance life of the coolant.
A vision-type broken-tool sensor (Vision B.T.S.) comes standard, supporting unattended operation by validating the condition of cutting tools after each tool change. By creating a silhouette of the cutting tools, Vision B.T.S. is also able to evaluate the size and approximate weight of the tool.
This information can then be applied to automatically set the tool-change speed to the appropriate setting (fast, medium or slow). The Vision B.T.S. system has fewer moving parts and requires no physical contact with the cutting tool, resulting in enhanced, long-term reliability and no risk of chipping delicate tool materials, such as polycrystalline diamond (PCD).
With the addition of the new Professional 6 (Pro6) control, the a71nx is equipped with two of Makino’s latest forms of advanced motion control to minimize non-cut time:
- GI Drilling is a unique G-code drilling cycle that enables the spindle and tool to arc from hole to hole instead of following a square path. This simple change reduces non-cut time by as much as 15 percent on common hole-pattern drilling.
- GI Milling is designed to improve performance in 2-D milling. GI Milling lets the user define a corner-rounding tolerance on each milling path. Even a small tolerance enables the machine to quickly flow through the cut path, completing milling paths in less time.
