MACHINEBASE
The mpmc is a modular, inclined-bed turning & milling machinewith efficient chip removal. The ergonomic design of the machine
guarantees comfortable and safe operation. The wide base, theexcellent guide ratio and the configuration of the guideways ensurestability and prevent vibration during operation, even under extreme
cutting conditions.

TECHNICAL FEATURES // weingartner.com

A ROBUST AND
ERGONOMIC DESIGN
Every major machine component has been designed with stringent safety features in mind. These
aspects combined with the solid structure of the machine are crucial to meet the mpmc’s highperformance expectations. The heavy machine bed achieves highly effective shock absorption
and accuracy, even when operating under maximum load. The full working load is always
centered to the base of the machine, thus preventing any vibrations from being transferred
across critical components.

Due to the ergonomically well-engineered concept of these machines, the highest level ofcomfort is provided for the operators. Barrier-free access to the machining area for tool, andworkpiece inspections is the prerequisite to eliminate accidents during daily operations on amachine tool.

INNOVATIVEDESIGNThe mpmc has earned its reputation as an innovative solution provider due to very specific integrated features,
giving it the impressive ability to completely machine really complex workpieces. The aim is to produce at

higher performance rates and with greater accuracy in comparison to similar machines on the market. Its
efficient operation maximizes production output and keeps maintenance costs at a minimum.

MASTER SLAVE DRIVE
IN B, C, Z – AXISUNIQUE B-AXIS FOR SWIVELINGOF MACHINING HEADSSTRONG AND POWERFULHEADSTOCK

A master-slave drive-system for the B, C and Z-axis isincorporated for precise positioning accuracies. The Z-axis
is driven by a rack-and-pinion drive instead of a ball-screwspindle. This keeps service- and repair costs down, as well as
significantly reducing noise levels during operation.

The B-axis structure is similar to the C-axis with integrated“master-slave” technology, where two servo motors withhigh-ratio gears are engaged on a central gear. The inhouse developed B-axis clamping mechanism allows infinite
indexing of the machining-heads in any angular position.
A hydromechanical clamping mechanism is used insteadof a Hirth-Joint indexing system. This also functions as anoverload protection and prevents damage in the event of any
kind of collision. A re-alignment procedure, or in other words
a mechanical repair interruption by a service technician is
not necessary with the advanced B-axis mechanism. A highresolution direct measuring system ensures the position
accuracy of ± 3 ArcSec.

The nature of its core function demands robust power steered
with absolute precision. Driven by two powerful AC main
spindle motors complete with automatic switch gearbox, atwin-drive system to run the turning- and milling operations,and hydraulically actuated power chucks, the headstockis guaranteed to operate flawlessly in any application.
It’s positioning accuracy of ± 3 ArcSec, controlled by ahigh-resolution direct measuring system, delivers precise
machining results.

Master and slave system:- The master motor determines the position- The slave motor works on a defined torque against themaster motor to eliminate backlash in the gears- Guarantees high accuracy- Increases torque

INTERCHANGEABLE MACHINING HEADS WITH AN AUTOMATIC PICK-UP-SYSTEM

To save manufacturing time and costs, and to maximize productivity, the mpmc can complete an entire
workpiece with only a minimal number of setups. It has the capability to perform all machining duties usuallyprocessed by several different machines, making it highly versatile.

Multiple machining heads are stored in a pickup station and are readily available to be exchanged by theautomatic pick-up quick-clamping device which selects the right head for the corresponding process, e.g.,
HSC-milling, bottle boring, trochoidal milling, slot milling or grinding.

COUNTER SPINDLE SYSTEM
The requirements on multi-task machines are becoming
more complex, and idle times in all processes have to be
reduced. Thanks to the counter-spindle system, complete
machining of a workpiece in one single setup has become
reality.

SOFT LANDING
The mpmc series is designed for heavy duty machining up
to 60 tons, 15 meters turning in length and 2 meters ofworkpiece swing diameter. Larger workpiece dimensions
can be accommodated on request.
A soft-landing system with prismatic support pads isincorporated into the design to ease the loading andunloading of large and heavy workpieces (e.g., work rollers).

TECHNICAL FEATURES // weingartner.com

STEADY REST
On special request, a steady rest solution with CNCcontrolled support movements is available for heavy
workpieces. The support rollers, or the hydrostatic support
pads can be used alternately on the same steady rest unit.
What makes it unique is that it allows a correction of theworkpieces’ center position under full load. This eliminates
the procedure of lifting the workpiece with the crane,
correcting the steady position and re-loading it back to thesteady rest, which is common on other machines.

BORING BARS AND
SPECIAL TOOLING
The storage station for boring bars and other long andheavy tools is situated above the headstock or at the endof the machine bed, i.e., behind the tailstock. Dependingon the machine size up to four storage stations can beaccommodated at each location. A separate heavy-duty
magazine is available if a larger number of heavy special
tools is required.

TOOL HANDLING
Keeping up with the times means implementing current, intelligent automation technologies
with the aim of improving the performance of machine tools. Efficient processes require
tailor-made solutions which optimize workflows. The mpmc is customizable to meet yourdesired production objectives.
Basic applications use a conventional chain magazine in combination with an independent
shuttle which can be located at the head stock or the tail stock end of the machine base.

TOOL HANDLING & AUTOMATED SOLUTIONS // weingartner.com

The tool change itself can take place in any longitudinal position of the Z-axis, during themachining process. All required tools are made available simultaneously, thus guaranteeing
the shortest possible changeover times.
Complex applications require a more sophisticated handling method to store and supply aseries of prearranged tools. For these purposes, the entire handling of tools is automated andconnected to an external tool delivery feeder system.

AUTOMATED SOLUTIONS
Like with the automation of tools, the handling of workpieces can be
automated by connecting the mpmc to an external delivery feeder
system. If required, an AGV (Automated Guided Vehicle) can be installed
to safely handle and store workpieces. The automation is carried out
in accordance with all internationally required safety standards and is
Industry 4.0 enabled.
