The abrasives are put onto the grinding discs which are mounted to the planet
arms. This system ensures a quick change from grinding with abrasives to CBN-
grinding discs or to lapping discs.
For smaller gate valve seats (DN 40, 50 ,65), solid grinding discs are provided
(model VM1350(S) only).
The solid grinding discs consist of:
• a ball joint coupling with ball joint for self-alignment of grinding discs
• solid grinding disc
• abrasives
The solid grinding discs are covered with self-adhesive abrasives.
Before machine operation, the Gate Valve Grinder has to be mounted to the gate
valve body by means of a tilting adapter with clamping elements (included in basic
scope of supply). With this tilting adapter, the machine can easily be set up and
centred to the valve seat. In addition, it enables the operator to apply the required
grinding pressure by tilting the machine against the valve seat and to take the
machine system out to change the abrasives without dismantling the tilting adapter
and its clamping elements.
The machine configuration with electric drive motor is started with the trigger but-
ton. The machine spindle is rotating as long as the trigger button is being pushed.
For permanent operation, the trigger button can be locked.
The spindle speed can be adjusted at the top of the electric drive motor.
The machine configuration with pneumatic drive is started by pushing the red
safety button of the maintenance unit. This maintenance unit is available as an
option or it can be supplied by the customer.
To increase the speed range, the electric drive motor is equipped with a 2-stage
mechanically switching gear.
Due to the fact that the pneumatic drive motor has already a wide range of adjust-
ment, an additional gear system is not necessary.
The Gate Valve Grinder and accessories are delivered in high-quality, durable car-
rying cases with foam inlet for safe transportation and storage.
