Valgro Coil / Strip grinding, and polishing machines designed for “wet” activities include a coolant recycling mechanism built into the machine. The used coolant, known as “swarf,” is collected at the bottom of the grinding heads and sent to a collecting system, where it is filtered to remove any metal particulates and then returned to the system as a clean coolant.
Heavy construction made of welded steel and spinning elements that have been dynamically balanced provides precise work that is not subject to vibration. Processing may be done simultaneously on either one side or both sides using a single head or several heads.
Valgro grinding and polishing lines are known all over the world for being reliable, sturdy, and easy to use.
The abrasive belt used in Valgro grinding and polishing systems are made for corrective grinding and/or finishing.
Applications, grinding “dry,” or with a flood of coolant on ferrous or non-ferrous alloys.
