Semi-Enclosed CNC Metal Milling Machine With Linear Tool Changer

The CNC metal milling machine is controlled by a CNC system and has an integrated automatic tool changing system. It is a high-precision CNC metal processing machine. The linear tool magazine can accommodate five tools of different sizes and functions at a time. The tools can be automatically replaced according to the shape of the product and different processes during processing. The tool replacement can be completed within a few seconds without manual intervention. After the tool replacement is completed, the automatic tool setting instrument is used to automatically calibrate the tool. This allows a complex workpiece to be clamped only once on the workbench to complete all processing steps, reducing the time wasted due to manual tool change or changing to different machines. In addition, since the workpiece has been clamped less frequently, the accumulated precision errors caused by multiple clamping of the workpiece are also reduced, which can significantly improve the processing accuracy and achieve efficient and precise processing of high-precision metal molds. It is very suitable for metal mold engraving, milling, drilling, grooving and other process processing.

Automatic tool-changing CNC metal milling machines have become indispensable CNC automation machines in the modern mold manufacturing industry through their four core advantages: improved processing efficiency, guaranteed processing accuracy, support for complex workpieces, and optimized processing costs. Through the cooperation of the CNC system and the automatic tool-changing function, it can effectively reduce more than 40% of the labor input cost. And because the workpiece can be clamped once, it avoids the deviation caused by traditional multiple clamping and reduces processing waste. It is very suitable for various high-precision work scenarios, such as automobile manufacturing, aerospace, watch manufacturing and other industries. Whether it is small-batch production or large-scale production, it can easily handle it and provide support for various high-end manufacturing industries.

How Does the Automatic Tool Changing of the CNC Metal Milling Machine Work

Before processing, when programming, the tool parameters should be set in advance. When programming, the software setting program automatically calls the order of required tools (such as roughing milling cutter → finishing tool → drilling tool), realizing continuous processing from roughing, finishing, drilling and other processes at one time, shortening the production cycle.

When changing tools, the control system drives the XYZ axes of the machine to coordinate and operate, and the tools are arranged in order on the tool magazine. When the control system executes the code to the tool change command, the tool change action is automatically triggered. At this time, the spindle will automatically move to the tool clamp position of the linear tool magazine, the Y axis slowly retreats, the tool clamp automatically clamps the tool handle, and then the spindle tool release mechanism releases the old tool, the Z axis rises to a safe height, moves to the top of the tool to be used, the Z axis descends, the spindle locking mechanism clamps the tool handle, the Y axis moves forward, and the tool is removed from the tool magazine. The tool change is completed. After the tool change is completed, due to the different lengths of the tools, the machine will automatically move to the position of the automatic tool setting instrument for automatic Z-axis height calibration. No manual calibration is required, saving time and improving efficiency.

Features of Metal Milling Machine With Automatic Tool Changing Kit

• Improve processing efficiency. Traditional processing requires manual tool change, and each tool change takes several minutes. Using automatic tool changer, tool change can be completed in a few seconds.
• Continuous processing of multiple processes. Through the tool library pre-setting in the tool library, the system automatically calls the tool during processing to achieve one-time continuous processing of multiple processes and shorten the production cycle.
• More suitable for mass production. In the mass production of mold parts, automatic tool change can also significantly improve production capacity and reduce costs.
• Eliminate errors. Manual tool change and repeated clamping of workpieces will cause the error accumulation of workpieces. Using automatic tool changer can complete all processing procedures in one clamping of the workpiece.
• Adapt to a wide range of materials, can process copper, aluminum, steel, iron and other metal materials, meet the production of various injection molds, die-casting molds, stamping molds and other molds.
• Reduce manual dependence. A single machine can run unattended for a long time, reducing labor costs and human errors.
• Optional fourth or fifth rotation axis to increase the scope of machine use.
