The DMU 65 monoBLOCK from DMG MORI offers high-tech at an attractive price while setting a new benchmark in its class with its convincing performance features.

In its flexible extension ranges encompassing the five-axis machine with its dynamic NC swivel rotary table, the DMU 65 monoBLOCK masters all disciplines in milling technology, from roughing through to finishing at an uncompromisingly high level and at a very attractive price. With its DMU 65 monoBLOCK, DMG MORI is offering a world-class machine for all fields of industry.

The uncompromisingly high quality of the DMU 65 monoBLOCK is apparent in its design details. In conjunction with the high-speed rotary axes of the NC swivel rotary table, these have resulted in a remarkable increase in dynamics, and, amongst others, the 45mm wide roller guides maximise process stability. Moreover, the DMU 65 monoBLOCK impresses with its three-point support for shortest possible start-up times. With a footprint of 8sqm, it is the most compact machine of its class.

Despite the small space requirement, the DMU 65 monoBLOCK has an extremely spacious machining compartment. With axis paths of 735mm x 650mm x 560mm (in X, Y and Z), the entire NC swivel rotary table surface can be traversed, allowing the workpiece to be machined in one pass – a decisive attribute for maximum precision and surface quality. Even oversize workpieces of up to 840mm diameter and a weight of up to 1,000kg can be loaded on the NC tandem swivel rotary table (optionally – 600kg in standard).

The operator has access to the DMU 65 monoBLOCK machining compartment through a 1,310mm-wide door opening, the 800mm table height allowing an ergonomic body position while working. Furthermore, given the heavy weight of the workpieces, the user will appreciate the fact that the well-conceived standard design allows for unrestricted workpiece loading by crane from above.

Simple and comfortable operation and loading of the 30, 60, 90, 120 or 180-position tool magazine has not been forgotten. Since the loading station is located in the front area of the machine, the operator can always work in his normal work environment. During preparations, the control panel can be swung directly towards the tool loading station. The fast sword-type tool changer reduces the chip-to-chip time to a convincing 4.9 seconds.

Further details of the DMU 65 monoBLOCK include the steep slants of the machining compartment, which allow the swarf to drop unrestricted, and the stainless steel lining of the machining compartment to ensure a long operating life. A wide centrally arranged chip conveyor permits fast and process reliable chip removal towards the rear of the machine.

Universal modular system

In addition to the design details, the DMU 65 monoBLOCK offers multiple options as a result of its modular system. These include modular equipment configurations for the motor spindles. The extensive modular spindle system, starting with a spindle speed of 15,000rpm (at torque of 130Nm) in the standard version, offers further application-oriented options with 20,000rpm (130Nm), 24,000rpm (100Nm) as well as a sturdy spindle with 15,000rpm and a 200Nm torque. There should be no doubt that all requirements will be met.

The available table variants have been designed to match the individual focus. In addition to the standard NC swivel rotary table for workpieces of up to 600kg, the portfolio includes swivel rotary tables with tandem drives in A-axis for workpieces of up to 1,000kg, or with Direct Drives in the A and C axes for the highest dynamics and accuracy, as well as the three-axis version for workpieces of up to 3,000kg.

The universal modular system of the DMU 65 monoBLOCK is complemented by production packages including an internal coolant supply of up to 80 bar, as well as a space-saving chip conveyor towards the rear of the machine. These features allow space-optimised placement of the machine on the shopfloor. Offering CELOS from DMG MORI with the 21.5-inch ERGOline Control with Operate 4.7 on Siemens 840D solutionline or Heidenhain TNC 640, DMG MORI is able to meet the preferences of almost every customer.

The DMU 65 monoBLOCK marks the beginning of DECKEL MAHO’s substantial expansion of the degree of flexibility in the field of five-axis machining. On the one hand, this refers to the integration of turning/milling technology. On the other hand, there will be the optional possibility of accomplishing ultrasonic-assisted chip removal of hard and brittle materials with ULTRASONIC, and of integrating an excellent milling and lasering tool on one machine with LASERTEC Shape.

DMG MORI Australia will be exhibiting at Austech 2017, at stand 634.
