Description
Technical Field
[0001] The utility model relates to the technical field of numerical control grinders, in particular to a flexible numerical control tool grinder. Background Art
[0002] Flexible CNC tool grinders are advanced grinding machines featuring versatility and automation, suitable for machining and re-grinding a wide variety of complex tool shapes and workpieces. They integrate CNC technology with flexible production techniques, offering flexible and efficient machining capabilities. Key features include an advanced CNC system, versatile grinding operations, automated control, tool inspection and measurement capabilities, flexible production capabilities, and high-precision, stable machining. Widely used in aerospace, automotive mold manufacturing, and machinery manufacturing, these machines provide a reliable solution for high-variety, small-batch, and customized machining needs, improving workpiece machining accuracy and production efficiency.
[0003] A traditional flexible CNC tool grinder is a complex mechatronic device that includes a CNC system, a spindle and spindle drive system, a fixture and positioning system, a grinding head / grinding spindle, an automatic tool change system, an automatic feed system, a cooling and lubrication system, a tool measurement and compensation system, and safety and protective devices. The CNC system acts as the control center, integrating a computer, CNC controller, input devices, and a display screen for programming, monitoring, and adjusting grinding process parameters. The spindle and spindle drive system ensures high-precision rotation of the grinding tool or workpiece and provides the required power. The fixture and positioning system is used to clamp and position the workpiece or tool to be processed, maintaining its accurate position. The grinding head / grinding spindle is responsible for the actual grinding operation and includes the grinding wheel, grinding head, grinding fluid transmission device, etc.
