Innovative technology of workpiece transporting between operations
- Automatic loading and unloading of workpieces
- Transporting of workpieces with the highest positioning accuracy
- Developing of optimal process taking into account specific characteristics of the movable and fixed spindles such as gravity force and chip disposal
- There are no connections or swivelling areas between the first and second setups
- Short cycle and idle time due to high speed of axis traverse
- High economy due to low cost per unit
Components and options
- Simple and reliable components proven in practice
- Wide range of options for an individual DVT machine
- Flexible application
- Short adjustment time
- Quick installation and commissioning
Exceptional ergonomics
- Highly acceptable spacious working area
- Unlimited freedom of movement
- Quick readjustment and low idle time
- Large viewing window for optimal control of machining process
Easy automation
- Independent loading and unloading
- No additional loading unit is required
- Easy readjustment for different part diameters
- Easy integration into production lines
Pick-up Technology

Machines with Pick-up technology are designed for machining using a suspended vertical spindle. The vertical spindle is designed for machining operations, automatic loading of workpieces and unloading of finished parts.
- Integrated automatic loading and unloading
- Short cycle time provided by the linear drive of cross slides
- High economy due to low cost per unit
- Multiple-machine operation: minimal required intervention of an operator
Workpiece transporting technology
Instead of two separate machines integrated into one production line with a help of automatic units only one DVT is required for two-side machining of parts with the highest accuracy. The technology is based on automatic loading of workpieces with a help of the movable spindle and their processing inside of the closed working area. Clamping device of the fixed spindle allow direct changing between two setups after processing without losing of quality. The movable spindle is loaded parallel to processing of the second side with further processing. The fixed spindle is unloaded with a help of the separate pickup device. The finished part is retracted by the separate automatic unit. It allows an operator clearly distinguishing between finished parts and blanks.
Turning-milling

The double unit used for processing of break disks performs milling in the direction opposite to turning.
Turning-grinding

Grinding of both sides of break disks is simultaneously performed with a tool and workpiece rotating.
Grinding

Grinding is performed with integrated automatic alignment and special grinding cycles with a help of corundum, CBN (cubic boron nitride) and others grinding disks.
Many-purpose mounting plate

The place for mounting of different processing modules for drilling, milling or grinding - a budget alternative to a turret head.
High dynamic motor spindles

High dynamic motor spindles with max. rotating speed 6500 rpm. Liquid cooling provides high thermal stability and low noise level. Integrated C-axis provides high positioning accuracy. Integrated control of clamping stroke lowers the labour cost of readjustment.
