Advantages

Since the launch in 1995 the patented transfer concept emerged as a constant of high-precision complete machining. The DVT is characterized by an utmost compact construction which sets standards compared to conventional machine configurations.

Automation

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.

Applications

The uniqueness of the DVT
Instead of two machines linked by automation and turning station you need
just one DVT to machine workpieces from two sides with the highest precision.
Automatic loading of the machine through the suspended spindle and
machining in a closed workspace provide the basis. The direct operation
into the clamping device of the fixed spindle after machining takes place
without loss of quality between the two clampings.

Parallel to the machining of the second side the loading of the suspended
spindle takes place again and the machining continues. Unloading of the
fixed spindle is managed through a separate gripper. The finished part is
removed by an integrated automation so that raw and finished parts are
clearly separated for the operator.

Step 1: Loading

Step 2: Machining side one

Step 3: Transfer of workpiece

Step 4: Machining side two

Step 5: Unloading

Step 6: Store

Options

Driven ToolsTurning, drilling, milling and tapping in only one chucking offers the bestmachining quality and reduces fixture costs. In order to reduce clampingpressure the workpiece will be supported by a tool located in the turret head. The use of the drilling- and milling-unit is based on a modular genericunit which can be used with single tools or multiple drilling heads.

NC lift-off-slide
The NC lift-off-slide was developed particularly for brake disk
manufacturing. It can be applied to all flat surfaces. Two cutters can
operate simultaneously.
