What is the difference between a flat bottom milling cutter and an end milling cutter? The difference between flat bottom milling cutters and end milling cutters, let's first take a look at several classifications of milling cutters. Firstly, milling cutters are generally divided into the following categories: 1. Flat end milling cutter, for precision or rough milling, milling grooves, removing many blanks, small areas of horizontal planes, or summarizing precision milling; 2. Ball end milling cutter for semi precision milling and precision milling of curved surfaces; A small knife can finely mill small chamfers on steep surfaces/straight walls. 3. Round nose milling cutter, used for rough milling with small surface changes, fewer narrow and concave areas, and more relatively flat areas. Titanium flat bottom milling cutter 4. The flat end milling cutter has chamfers, which can be used for rough milling to remove many blanks, and can also be used for fine milling of small chamfers on flat surfaces (relative to steep surfaces). 5. Forming milling cutter, including chamfer cutter, T-shaped milling cutter or drum cutter, toothed cutter, and inner R-cutter. 6. Chamfer cutter, which has the same shape as the chamfer and is divided into milling cutters for circular chamfering and oblique chamfering. 7. T-shaped cutter, capable of milling T-shaped grooves; 8. Tooth cutter, milling various tooth shapes, such as gears. 9. Coarse leather cutter, designed for cutting aluminum copper alloy, can be quickly processed Aluminum alloy flat bottom milling cutter There are two common types of materials for milling cutters: high-speed steel and hard alloy. The latter has higher hardness and stronger cutting force compared to the former, which can improve the speed and feed rate, improve productivity, make the tool less obvious, and process difficult to process materials such as stainless steel/titanium alloy. However, the cost is higher, and the tool is easy to break when the cutting force changes rapidly. From the above content, it is clear that a flat bottom milling cutter is actually a type of end milling cutter, with many different shapes. Generally, milling machines and CNC milling machines are used to summarize grooves and straight lines, and milling and boring machining centers are used to process cavities, cores, and surface shapes.
