DVH Series – The Latest in Turning

DVH Series – Single Spindle
Turning Machines
Pick-up Turning Machines by MAG Hessapp
As powerful motorized spindles became available in the early 90s, MAG
Hessapp, a traditional builder of vertical turning machines, recognized their
potential and developed – as one of the first machine tool manufacturers
in the world – an inverted spindle vertical turning machine – the launch of
the DVH series. Since their successful introduction to the market in 1991
the DVH range of vertical turning machines has been continuously improved
and perfected. MAG Hessapp today offers an extensive range of invertedspindle
vertical turning machines to satisfy a wide variety of different
requirements.
The series comprises 4 different basic versions:
DVH 500 advanced model to meet highest demands
DVH 250/320/400 best price and performance
DVH DUO twin spindle pick-up-type vertical turning machine
DVH 4X self-loading 4-axis vertical turning machine
DVH 400 / 500
available also as mirror-inverted machine

Machine Units and Options
for Your Individual Machine
Driven Tools
Turning, drilling, milling and tapping in only one chucking offers the best
machining quality. There is no setup required between operations and the
number of fixtures required is reduced.
Part Gauging
For part gauging within the machine the motorized spindle, with the part,
contacts a measuring probe. Gauging outside of the machine has the
advantage that measuring can take place within the machining time, thus
increasing productivity.
Use of driven tools
Use of tool-holder with long boring bar
There are 2 systems available:
, Measuring system with workpiece specific items such as gauges,
man drills
, CNC measuring machines with freely programmable measuring cycles
Workpiece Temperature Control
Before starting a cycle the actual part temperature is measured by means
of a contact-less sensor and transmitted to the CNC as an off-set value.
Tool gauging
By using software developed by MAG Hessapp the operator is able to gauge
new tools with extreme precision and to correct them in the tool magazine.
Off-centre milling operation
Tool-block with additional drilling/
milling drive

Tool breakage and wear control
In order to increase their up-time DVH machines can be equipped with a
cutting edge and collision monitoring system. In case of tool-breakage,
excessive tool wear or collision an emergency shutdown module stops the
feed axes instantly.
Measuring probe
Turn-grinding
Both braking surfaces are ground simultaneously, workpiece and grinding
wheel rotating.
Turn-milling
Milling unit on DVH 500, with milling cutters rotating in opposite directions,

Material Handling Systems
Flexible, Trouble-free, Adapted
to the Job
Flexible handling systems
Our relationship with you as our customers starts with your workpiece.
We look at your machining challenges, your quality and your output
requirements.
Based upon these individual details we develop a process, which centers
around your wokpiece. The result of this process development is your
custom-engineered vertical turning machine.
The DVH family of machines lends itself very favourable to the composition
of automated turning cells and lines. Whether your are looking for multiple
machine operation, production through break-times or during personnel
reduced shifts, a comprehensive range of job-adapted peripheral equipment
is available to match your needs. This includes equipment for part identification,
loading, gauging and surveillance.
Options for DVH-machines
The flexible standard workpiece conveyors can be easily adjusted to a new
workpiece by quick adjustment.
Use of standard workpiece conveyor (small diameter and tall)
Same conveyor used brake rotors (large diameter and flat)
