Manhole cover machining refers to the process of finishing the dimensions or performance of manhole cover components by mechanical equipment or manual work .it can be divided into shaping processing and polish processing according to the difference in processing ways.
The machining process of manhole cover refers to the intermediate process of making products from semi-finished to finished products. Modern enterprises organize and guide production by principle of systems engineering , and see the production process as a production system with inputs and outputs.
During production process, any change of the shape, size,properties and so on that producing manhole cover to make it into a finished product or a semi-finished product is called process. It is a major part of the production process.

Our company has two domestic advanced modern machining workshops with an area of nearly 1,000 square meters, multiple automatic and more than ten manual machining production lines, which meet different types manhole covers mechanical processing at the same time. It improves work efficiency and customer products is guaranteed.
