The choice of cutting tools is one of the important contents in the CNC machining process, which not only affects the machining efficiency of the machine tool, but also directly affects the machining quality of the parts. So how to choose the tool according to the CNC bus processing machine? How to choose a tool for CNC bus processing machine:    1. Choose CNC bus processing machine tools according to the cutting performance of the part material, such as turning or milling high-strength steel, titanium alloy, and stainless steel parts. It is recommended to choose indexable cemented carbide with good wear resistance. Tool.  2. Select the tool according to the machining stage of the part's CNC busbar processing.   (1). The roughing stage is mainly to remove the margin, and the tool with better rigidity and lower precision should be selected.   (2) The semi-finishing and finishing stages are mainly to ensure the machining accuracy of the parts and the quality of the products, and the tools with high durability and high precision should be selected.   (3) The precision of the tools used in the roughing stage is low, while the precision of the tools used in the finishing stage is high.   (4). If the same tool is selected for roughing and finishing, it is recommended to use the tool eliminated from finishing for roughing.  3. Select the tool and geometric parameters according to the characteristics of the machining area of u200bu200bthe CNC busbar processing machine.   (1) When the part structure allows, a tool with a large diameter and a small length-to-diameter ratio should be selected.   (2) When processing aluminum, copper and other soft material parts, you should choose an end mill with a slightly larger rake angle, and the number of teeth should not exceed 4 teeth.  4. Select the tool according to the surface size of the workpiece to be processed by the CNC busbar processing machine.   (1). During production, the peripheral contour of the plane part is processed, often using an end mill.   (2). When milling a plane, you should choose a cemented carbide insert milling cutter.   (3). When machining bosses and grooves, select high-speed steel end mills.   (4). When processing the surface of the blank or roughing the hole, a corn milling cutter with carbide inserts can be selected.  (5). For the processing of some three-dimensional profiles and contours with variable bevel angles, ball end milling cutters, ring milling cutters, tapered milling cutters and disc milling cutters are often used.  On the CNC bus processing machine, all tools are pre-installed in the tool magazine, and the corresponding tool change actions are performed through the tool selection and tool change instructions of the CNC program. Corresponding standard tool holders suitable for the specifications of the machine tool system must be selected so that the tools used in the CNC bus processing machine can be quickly and accurately installed on the machine tool spindle or returned to the tool magazine.
