Multifunctional and effective grinding wheel and belt head
- It is made up of still left/right shifting unit, grinding & gouge head vertical rotating relationship flange, grinding & gouge head horizontal rotation device, grinding & gouge head facet swing protecting against unit, grinding & gouge head, grinding motor, welding seam abrasive wheel and grinding unit, root pass potent abrasive belt grinding gadget (abrasive belt get in touch with wheel,tight and aspect swing protecting against gadget ,), Pneumatic continual force relocation system, computerized blade lifting device and du EPT removing go over.
- Grinding & gouge head correct/remaining horizontal transferring unit consi EPT of motor, special reducer, lateral little slide guidebook rail. The perform of the right/remaining horizontal relocating unit is to hold the grinding centerline coincides with the device middle line following ninety diploma rotating.
- Grinding & gouge head vertical rotating link flange consi EPT of motor reduction device. The purpose is to facilitate the abrasive belt to parallel with welding seam surface even though grinding the cladding welding seam.
- Grinding rotation device is made up of rotation ring and supporter. ±90 diploma can be altered as vessel interior, external longitudinal/ circumferential seam conditions.
- Grinding & gouge head aspect swing lock preventing unit consi EPT of lateral sliding unit and relevant tight lock system. The abrasive wheel can automatically adju EPT the route through sensor detection by subsequent welding seam. The objective is to avoid abrasive wheel blocked and hazardous happens even though the grinding route deflection happens since the anti-floating roller with no using. Limited lock device is to maintain the abrasive grinding keep track of no deflection.
- The total grinding & gouge head and grinding belt are using same beam and motor system, constant stress relocation and automatic blade lifting technique. The only variation is that the abrasive belt has different wheel tight and aspect swing protecting against unit and addresses.
- The abrasive belt can fulfill vessel internal and exterior grinding

PLC manage method
The grinding and gouge device makes use of Siemens PLC (S7-300) program. To make it straightforward to operate the machine, the transmitter cupboard management largely relies upon on hand-held operation box management. Transmitter cupboard is situated on the back of machine, each purpose grinding & gouge head and equipment are with independent fa EPT interface. Pneumatic device: air resource .4~.8mpa, it is with oil-drinking water separator. Elements are utilizing SMC brand. Grinding/gouge head coordinate handle is pushed by ongoing guide variable frequency. The regular pressure relocation system can remove the beam deflection throughout grinding and gouging, which means the abrasive wheel is usually perpendicular to the axis of the vessel. Required Linear velocity of vessel roller is 0.1-3m/moment for the duration of grinding or gouging
