How to operate the installation of CNC surface grinder accessories

When installing workpieces on a CNC surface grinder, if a sizing block is required, a copper plate of a certain thickness should be placed between the sizing block and the grinder worktable, and a thin copper plate should be placed between the sizing block and the worktable to prevent marks from appearing on the surface of the worktable and workpiece. When using the glue block, it should be noted that the glue block and fixing screws should be as low as possible, and the glue block should be placed in the fixed area within the processing range of the workpiece to avoid damage caused by the glue block impacting the cutting head and tool holder. When loading and unloading workpieces, they should be handled carefully to minimize friction and movement on the workbench. It is prohibited to use a multi angle grinder worktable as a support point to drag the workpiece upwards (seriously scratching the grinder and affecting its flatness); It is strictly prohibited to place tools such as sockets, screw wrenches, screws, rubber hammers, as well as grinding machine workbenches, oilstones, files, etc. on the grinder to prevent collisions. Start the grinder and check if the lubricating oil is sufficient and if the grinder is functioning properly. Then turn on the grinder power (when turning on the grinder power, turn the knob from the "off" position to the "on" position), turn on the control panel power switch, and turn off the emergency stop button.

Generally, important cylindrical surfaces are used as coarse positioning benchmarks, and the center holes at both ends of the shaft are used as fine positioning benchmarks. The reference surface should be as uniform, dynamic, and mutual as possible, and multiple surfaces should be machined simultaneously. The central hole is the unified positioning and inspection benchmark for workpiece processing. Its quality is very important and its preparation is relatively complex. Usually used for supporting journal positioning and central cone hole rotation (drilling). Then locate the center hole and complete the rotation of the outer circle. Position the outer ring and roughly grind the conical hole. Central hole positioning and outer circle precision grinding. The positioning and precision grinding (scraping or grinding) of conical holes are carried out using the outer circle of the bearing journal to ensure the accuracy of the conical holes meets the requirements.

For hollow shafts or short shafts where the center hole cannot be located, they can be positioned, clamped, and torque transmitted through cylindrical surfaces using universal fixtures such as three jaw chucks and four jaw chucks, or various high-precision automatic centering fixtures such as liquid plastic thin-walled centering fixtures and diaphragm chucks.

When processing the outer surface of hollow shafts, various plugs or pull rods with central holes are often used to install the workpiece. Small taper holes are commonly used as plugs, while large taper holes are commonly used as pull rods and core shafts with plugs.
