As a consumable item, the tool in machining has a certain life. Different materials and different specifications have different life spans. For high-volume machining, tool consumption also plays an important part in processing cost.
Therefore, improving the tool life, controlling the tool consumption and reducing the processing cost, and improving the production efficiency are the common pursuit of the majority of mechanical processing plants.

In today's machining, tool repair is a way to increase tool life. However, the traditional manual equipment repair tools can not meet the user's needs in terms of accuracy and efficiency, reliability and safety. At the same time, it is necessary for the enterprise to train professional tool grinding personnel, which adds a part of labor costs.

In response to the above problems, combined with the existing resources of the company, developed a set of technical solutions for the use of CNC machining centers to achieve tool grinding automation:

First of all, because the tool material is generally hard, only the grinding process can be used to change its shape. Grinding discs of different materials are suitable for grinding tools of different materials. The size of the abrasive grains used in different parts of the tool is also different to ensure the best combination of cutting edge protection and processing efficiency.

Therefore, the first problem to be solved by the CNC machining center is the type of grinding wheel and the way of clamping. Considering that the alumina grinding wheel is cheap and easy to repair into different shapes for grinding complex tools, it can be ground. The tool is too single, and it is difficult to install and replace frequently, so use a diamond grinding wheel that can grind more tools.

The most critical technique for repairing a tool with a CNC machining center is the use of the probe. The high-precision probe can be used with the machining center input test program to realize the tool grinding zero and the tool grinding position and the number of grinding tool edges. Several variable measurement results are fed back to the CNC system of the CNC machining center to input the pre-programmed sharpening program for tool grinding.

Finally, to achieve the sharpening of the knife, we have to join the automated assembly line:

By self-designing, the tray for placing the tool is obtained, so that the robot can accurately position the tool, thereby realizing the loading and unloading of the tool, and the CNC machining center, as well as the assembly line device and the final high-precision detecting device, to realize the tool grinding. Fully automated.
