Machining knowledge of stone columns and Roman Columns

The grinding and polishing of the cylinder is generally carried out on the lathe with pneumatic or hydraulic pressure grinding head, and the abrasive installed on the grinding head can be quickly replaced. The abrasive of the grinding cylinder is usually ring type, and the end face is in contact with the cylinder, and the line grinding and polishing method is adopted. Depending on the stone material being ground, the grading of grinding and polishing abrasive is also different.Such as processing granite, can use 5 kinds of abrasives of different thickness, processing marble can use abrasives.

Due to the railings, vases and other products of the contour line concave and convex changes in the ups and downs, the use of the ring type abrasive grinding processing is difficult, so the use of manual grinding special-shaped rotating body of the simple grinding equipment, complete the railings and other products polishing processing.

After finishing the polishing of the cylinder, a diamond saw blade can be used to cut the two end faces of the cylinder to make its length and size meet the requirements of the finished product.It must be noted that the Angle between the end face and its axis after cutting should be slightly less than 90 degrees, so that when installing, the joint can be small and beautiful.

The packaging of the cylinder is divided into two steps. First, the cylinder is sealed with a plastic film with a thickness of 0.5mm, and then it is fixed in the wooden bar.When packing and transporting, we must pay attention to avoid bumping against the cylinder.

The cutter used to process the grooves of Roman Columns is generally a milling cutter set with welded diamond blocks, which is similar to a diamond roller.The cutting section of diamond agglomerate is arc shape, and the width of diamond agglomerate determines the width of groove, so as to process the groove of curved section.
