Features of single-tooth replaceable thread milling cutter head:
Multiple edges are processed simultaneously to ensure processing efficiency and large margin milling
The cutting edge is finely sharpened, and the cutting is brisk;
The blade and the tool holder are connected in a polygonal manner to ensure stability and rigidity requirements;
Good chip removal performance;
High surface finish can be obtained;
High size accuracy;
Precision machining for processing deep hole threads, large aperture, and large pitch, with long service life;
Select different blades to machine straight pipe threads and tapered pipe threads. One blade is not limited by inner, outer, left and right handed threads;
Reuse to effectively save costs.
Thread milling cutter processing case
With the progress of the times, the CNC industry is becoming more and more widely used in my country's large and medium-sized machining industry. For thread processing of some large parts, traditional thread turning, taps and dies can no longer meet the needs of production. Today, when CNC milling machines or machining centers are widely used, three-axis linkage machine tools are used for thread processing, which has changed the thread processing process and achieved good results.
1. Spiral milling internal holes
1. processing range
For blind holes or through holes with large diameters, spiral milling is often chosen because twist drills are too slow or cannot be processed. Moreover, since the tool selected in this method does not have a bottom edge, it is more suitable for machining with small depth of cut, high speed and large feed.
2. processing characteristics
Spiral milling for machining holes is a machining method based on the spiral cutting method. There is a feature of spiral milling: the Z-axis direction of the tool moves one cutting height for every spiral milling cycle.
3. Selection of thread milling cutters
Select a 16mm three-edge indexing milling cutter, and the tool speedS=3000r/min, feed amountF=2500mm/min.
4. description
This method is very distinctive in spiral milling of inner holes. The essence of programming is to compile a lower tool height as the spiral height into a subroutine, and cycle the spiral subroutine to complete the milling of the entire hole. This method for machining holes is not affected by factors such as milling cutter specifications, so it is ideal for application in CNC milling machines and machining centers.
5. Application examples and program writing
In the parts drawing shown in Figure 1, threads are to be processedM36×1.5mmbottom hole.
First, calculate the thread M36×1.5mmThe bottom hole diameter is: nominal diameter-1.0825×P(pitch)=36-1.0825×1.5=33.75mm。Confirm that the machining blank of this part is80mm ×80mm ×30mmOf45Steel, the selected tool is16mmThree-edge indexing milling cutter, tool speedS=3000r/min, feed amountF=2500mm/min。Arc import point isA(Figure2)In0ACreate tool compensation for segments, and the arc export point isBIn0BParagraph cancels the knife compensation.
