DVH 250 / 320 I DUO / TWIN

VERTICAL DOUBLE SPINDLE
PICK-UP MACHINE SERIES
DVH 250 / 320 I DUO / TWIN

A Compact High-Productivity Turning
System Highly Productive Vertical
Machining with Optimized Idle Times
The Double Pick-up Spindle Vertical Machine DVH 250/320 I DUO with
extremely short loading cycle is suitable for mass production of workpieces
up to 320 mm.
Z1
The two side-by-side motorized spindles can be moved and adjusted independently
in Z-axis. This is exactly the same for the two turrets in X-axis
which are located on slide units.

, Flexible use, machining of two workpieces parallel or in sequence
(1st and 2nd operation)
, Innovative loading automation
, Short idle time by reduction of moving masses
, High availability
Building Blocks and Options
, Simple and reliable building blocks well tested in production
, Flexible to use
, Short assembly periods

, 12 indexing locations
, Rotating tools (option)
, Slide unit with ball screws and strong dimensioned linear
guide ways, linear position measuring system
Machine Bed
, Inherent rigidity of machine frame
, Strong-walled and heavily ripped

Idle Times Utilized for Loading
Significant reduction of idle times for short-cycle operations.
NC-shuttle
, The four part locators on the shuttle can be designed individually
, For different parts the shuttle has workpiece frames
, Part feeding to shuttle from containers or conveyors can be handled
by various load/unload systems
, Shuttle area is well protected against chips
The NC-shuttle moves into the working area
from the back side of the machine. In order to
realize quick part changeover there are two
rough part and two finish part locators on
the shuttle.
It is possible to have an easy connection to a central conveying system
as well as to a separate buffer via a shuttle unit.

The DVH TWIN
Double Benefits

Two Spindles – double output.
The DVH TWIN enables extremely fast machining.
1 The Compact Concept
The DVH TWIN is the most compact two-spindle machine in its class.
The intelligent layout of the components in the work area has reduced
installation space to a minimum.
Your Advantage:
, Minimal space required
1
2 Clever Workpiece Handling
The processes have been perfectly optimized. The result: the fastest
two spindle machine in its class. Since workpiece handling can occur
outside the main operating time, the spindles are not subjected to
waiting times.
Your Advantage:
, Unprecedented machine speed due to optimized processes
, High output
2
3 Easy Operator Access
Thanks to its excellent accessibility the DVH TWIN is exceptionally easy
to equip and set up
Your Advantage:
, Set-up and maintenance times are reduced to a minimum
4 Productivity Increase
Designed for uncompromising speed: Acceleration of up to 1.2 g and
rapid feed rate of 120 m/min. can be reached in the X-axis
3
Your Advantage:
, Minimum chip-to-chip times and thus shorter idle times
5 The Space-saving Concept
Now, machines can be positioned side by side, since lateral
access is no longer required (see installation layout)
Your Advantage:
, Minimum installation space required
, Cost savings due to short concatenation

What Really Counts is Productivity
You Can Turn and Twist it Any Way You Like
Example 1: Parallel Machining
On the DVH TWIN, both spindles can perform the same machining operation.
Combining linear motors with direct absolute measuring systems and
two pick-up stations makes this a particularly fast and precise operation.
Your Advantage:
, Fast
, Compact
, Flexible
, Precise
, Excellent price-performance ratio
Example 2: Double-side Machining
When machining the front and back of the workpiece in two clamping
operations, the turn-over unit feeds the workpiece to the second spindle.
Rough and finished parts for workpiece changes are supplied while the two
spindles are still operating. No waiting times are generated.
