Our Sink top seam grinding machine is designed to grind seams between the surface and the bowls, which are welded together.  The sink top grinding machine, which is equipped with a rotatable clamp, does fix the sink firmly in the rotary clamping support and grind the seam according to its shape. To grind one bowl only takes less than 1 minute. The workbench will fix all sinks tightly and rotate them with controlled speed while the grinding arm grinds the welded seams.
Comparing with manually grinding machines, this machine could assure every spot of the welded seam will be grinded with the same pressure and speed.  Sinks grinded by the machine will be smoothly and brightly without any scratching. This Sink top welding seam grinding machine is very popular among sink manufactures.
