Similarities And Differences between Thread Milling Cutters And Taps

---The main differences between thread cutters and taps are in processing methods, efficiency, precision, application range and conditions of use. ‌

Processing methods Thread milling cutter: Through the three-axis linkage of the CNC machine tool, the rotation of the milling cutter is used as the main motion to generate the thread diameter; the workpiece performs feed motion to generate the pitch. ‌

1 Tap: Processing is performed by using a tool with grooves along the axial direction, which is suitable for the processing of medium and small-sized internal threads. ‌

2 Processing efficiency Thread milling cutter: The multi-groove design increases the number of cutting edges, which can easily increase the feed speed and greatly improve the processing efficiency. In the processing of long threads, choosing a blade with a longer blade can reduce the axial feed distance and further improve the processing efficiency. ‌

1 Tap: Although it has a simple structure and is easy to use, its processing load per tooth is large and the cutting speed is slow. ‌

Precision and surface quality Thread milling cutter: It has high processing efficiency, surface quality and dimensional accuracy, good stability, safety and reliability, and is suitable for a wider and more flexible use and application occasions. ‌Tap‌: Although it is highly practical, it has low precision and the tool is easy to wear.Application range

2‌.Thread milling cutter‌: It is suitable for processing internal and external threads of different rotation directions. The same thread milling cutter can be used for threads with the same pitch but different diameters. When processing blind holes, the thread milling cutter will get a complete thread profile to the bottom of the hole, while the tap needs to drill deeper.

"1‌.Tap‌: It is suitable for processing through holes or non-through holes, non-ferrous metals or ferrous metals, with strong versatility and low price.

Conditions and costs of use

2‌.Thread milling cutter‌: It requires the use of a three-axis linkage CNC machine tool, which is more troublesome to program, suitable for mass production, and the single production cost is higher.

‌Tap‌: It has a simple structure and is easy to use. It is suitable for manual operation and machine processing, and the cost is low.

‌

---The similarities between thread cutters and taps‌ are mainly reflected in the following aspects:

‌Same purpose‌: Both thread cutters and taps are used to process threads on workpieces to ensure that the workpieces can be tightly connected with other parts. Whether it is a thread cutter or a tap, its core function is to make internal or external threads to meet the needs of mechanical assembly‌

‌Similar processing principles‌: Both thread cutters and taps cut or extrude materials through rotation and axial movement to form threads. Thread cutters use milling, while taps use rotational cutting. Although the specific operation methods are different, their processing principles are similar‌

‌Overlapping application scenarios‌: In some cases, taps can replace thread milling cutters for shallow holes or small diameter threads, while thread milling cutters are more advantageous in high-precision and mass production. Both have their own advantages and disadvantages in different scenarios, and can be selected according to specific needs‌

‌Material adaptability‌: Both thread cutters and taps can be used to process a variety of materials, including metals, plastics, etc. Different materials may require different tool types and parameter settings, but the basic principles are the same‌

‌

‌

The usage scenarios of taps mainly include the following types:

Straight groove taps: suitable for processing through holes and blind holes, especially for processing short-chip materials such as gray cast iron. Since the iron chips remain in the groove, the thread quality is average.

Spiral groove taps: suitable for blind hole processing with a hole depth of less than or equal to 3D. The iron chips are discharged along the spiral groove to ensure high thread surface quality. Suitable for processing hard materials or large pitches.

Spiral tip taps (tap with blade inclination or tip taps): mainly used for through hole processing, iron chips are discharged downward, cutting torque is small, and processing quality is high. When using, ensure that all cutting parts are tapped to avoid tooth collapse.

Extrusion taps: suitable for processing through holes and blind holes, and threads are formed through plastic deformation of materials. Suitable for plastic materials, with high strength, high wear resistance and corrosion resistance, but the manufacturing cost is high.

Spiral groove tap: suitable for processing non-through-hole threads, especially for ferrous and non-ferrous metals

Spiral tip tap: suitable for through-hole processing of various materials, especially for high-strength materials

Extrusion tap: suitable for through-hole and blind-hole processing of plastic materials, such as iron plates, copper plates, aluminum plates, etc.

Thread milling cutters are widely used, mainly in the following areas:

Machinery manufacturing: Thread milling cutters are widely used in the automotive, aerospace, shipbuilding, machine tool and other industries to process various threads, such as internal threads, external threads, trapezoidal threads, serrated threads, etc.

Mold manufacturing: In the field of mold manufacturing, thread milling cutters can be used to process threaded holes in molds to improve the precision and quality of molds

Medical devices: In the manufacture of medical devices, thread milling cutters are used to process surgical instruments, dental instruments, etc. to improve the precision and quality of medical devices Electronic equipment: Thread milling cutters are also commonly used in the manufacture of electronic equipment, such as mobile phones, computers, televisions, etc., to process threaded parts and improve the precision and quality of electronic equipment

Other fields: Thread milling cutters can also be used in the construction, chemical, petroleum and other industries to process various threaded parts and

ole processing, cheap, but not very targeted
