August Hauerwas
Manufacturer of Grinding, Lapping, Milling and Turning machines
for all kind of sealing surfaces of valves of DN 8 - 2000 mm
Hauerwas Movema machines
stationary and transportable machines with eccentric
for grinding and lapping of sealing surfaces of valves of DN 8 - up to DN 400 mm
stationary and transportable (optional) machines
with eccentric for grinding and lapping of sealing surfaces
axial spring suspended machine spindle with scale for setting of working pressure
Tilting table with t-slots rotateable on scale
0-12° for easy set-up of valve casings
Machine spindle can be rotated by 190° for machining even larger valves behind the machine
Optional second tilting table can be mounted
for setting up valves on one table while machining a valves sealing surface on the
other table
Transportable use of Movema machines with
optional clamping device
Ball Mandrel as pick up of machining discs adapts to angle of sealing surface

Taumelus III-N: SPC-Control with electric height adjustment
Taumelus III-Standard: manual height adjustment
axial spring suspended machine spindle with scale for setting of working pressure
Tilting table with t-slots rotateable on scale
0-12° for easy set-up of valve casings
Machine spindle can be rotated by 190° for machining even larger valves behind the machine
Optional second tilting table can be mounted
for setting up valves on one table while machining a valves sealing surface on the
other table
Optional adjustable intermediate housing for quick and easy set-up of valves (T III-N)
Ball Mandrel as pick up of machining discs adapts to angle of sealing surface
extensive options to adapt to any kind of use
Hauerwas PLM
stationary machine with eccentric, reversing gear, electrical height adjustment and two tilting tables for grinding and lapping of sealing surfaces of valves of DN 8 - up to DN 300 mm
especially suited for valve manufacturers
two working tables with t-slots provide installation of second valve while first one is being machined
Machine table can be inclinated 0-12° for easier machining of slide-valves or wedges
axial spring suspended ball mandrels with scale for setting of working pressure
Ball Mandrel as pick up of machining discs adapts to angle of sealing surface
Hauerwas Portalmaschine
Vertically operating turning, grinding, lapping and milling machine for
general overhaul of sealing surfaces on slide-valves, wedges, valves, and flanges of DN 50 - 600 mm
Working methods: Turning, Grinding, Lapping and Milling with milling discs
When turning slide-valves, no re-clamping or rotation of the valve casing is neccessary for machining lower and upper sealing surface, resulting in best accuracy
SPC-Control with electric and additional manual height adjustment
Height adjustment speeds:
by SPC Terminal: fast, medium, slow*
by handwheel: slow*
* digital and optical readout for precise setting of cutting depth for turning
digital angle measurement system for easy setup and setting of angle of slide valve casings
adjustable end switches limiting travel of support during turning operation
Machine table with T-slots can easily be adjusted in 2 axis, additionally be tilted +/- 11°, and is hydraulically clamped
axial spring suspended ball mandrels for setting of working pressure during grinding and lapping
