Founded in 1995, Zidong Machinery Manufacture Co., Ltd. is a professional China rotating machinery manufacturer and designer in researching, developing and design all kinds of machines, equipment, lathe, machining, automatic and tools. ISO9001:2000 certified, we follow strict quality management criteria to provide high quality and cost efficient products. And We have gotten CE, GS and EMC approvals. We devote to carving CAD/CAM technology and CNC numerical control technology research OEM rotating machineries and development. By adopting assembly technology and choosing fine materials, We have moved towards good stability and gets the position in advertisement, woodworking and metal mold industries.

The Lapmaster line of dual side planetary fine grinding machines are specially designed and built to withstand extreme conditions within a production environment while requiring minimal maintenance. These units are available with fine grinding platens from 20" up to 55" in diameter, and are specially configured for each application. Depending upon the application, these machines utilize fixed abrasive diamond or CBN suspended in resin, metal, and vitrified bonds to grind a wide range of materials to very tight specifications.
The LFG series of twin wheel grinding machines are driven by three, variable speed motors for maximum process control flexibility. All three rotating machine components, the sun gear, top plate, and bottom plate, are independently controlled. Process down pressure requirements are pneumatically regulated and continuously monitored by a load cell.

The machine frictions the double seams on top and bottom to the bodies one and at a time. The machine is equipped with respective closing chuck which is already built in the machine. The machine is run with two seaming rollers frictioning single double operation. Double seam cans are effected by operating two rollers, thus doubling their thickness and giving additional strength on this machine and effecting the economy of solder.The machines are operated through a color graphical interface to a programmable controller. The custom designed software prompts the operator for specific operating parameters and stores up to 200 different lapping and polishing routines containing up to 8 different process steps which can be recalled for later use.
