Circumferential and Longitudinal Seam CNC Gouge and Grinding Machine

A special equipment is developed with grinding wheel and abrasive belt as abrasive tools, aiming at high pressure heavy container and combining the characteristics of new high efficiency strong abrasive belt and high speed grinding wheel. It is the ideal equipment for polishing heavy boiler, stainless steel container and similar large and medium-sized tank.

The machine consists of CNC cross manipulator, multifunctional powerful grinding abrasive wheel and belt head, dust removal system,electronic system and pneumatic control system.

It is applied to grinding and polishing the residual height of the longitudinal and circumferential welds on the surface of the outside of the cylinder, grinding and polishing the surfacing layer of the inner wall of the cylinder and cleaning the longitudinal and circumferential roots of the cylinder, such as:

(1) grinding of the internal and external longitudinal and circumferential welds of the tank:

(2) grinding of the stainless steel surfacing layer inside the tank;

(3) Grinding of surfacing layer on the inner surface of various head and butt welding slope mouth.

Major Component

1, It consists of base hold, level adjustment unit, column, rotating device, power driving system, Mechanical locking mechanism,cross slider/carriage, beam and related moving system. Rotating device between Base hold and column is driving by electricity.

2, Cross slider utilize reducer and Ball screw drive to control up and down. Beam front and back moving is driven by reducer motor and gear rack.
3, Column and beam guide rails are the oversea imported heavy load straight guide. Beam both ends can be equipped with multifunctional and powerful abrasive wheel and belt,dust removal system while it is also considered to leave other grinding &gouge head interfaces.
4, There is lift lugs beside column end which is a fixed type. Overhead head crane can lift without steel wire.
5, Cross sliders are installed with dust protection unit.
6, Staircases are provided on column for maintenance.
7, The deflection can be removed by grinding & gouge head constant pressure relocation mechanism.
