Bull Nose End Mill Specification Options
A bull nose end mill has a flat cutting bottom with a defined corner radius at the outside cutting edge. Tooling catalogs also commonly list this geometry as a концевая фреза углового радиуса.
General Dimensions
Use the following dimensions to specify the tool:
| Symbol | Измерение |
|---|---|
| D | Диаметр фрезы |
| R | Угловой радиус |
| ЛОК | Длина резки |
| д | Диаметр хвостовика |
| ОАЛ | Общая длина |
| Z | Количество флейт |
Check these dimensions together when selecting a standard tool or confirming a non-standard design.
Для нестандартных инструментов, send a drawing when available.
3-Flute Aluminum Series
OMIST offers a standard 3-flute series for aluminum and aluminum-alloy machining.
The confirmed series covers cutter diameters of approximately Ø1–Ø20 mm, with corner radii from R0.2 to R4 across the series. ЛОК, диаметр хвостовика, and OAL vary by cutter diameter and tool design.
Однако, not every diameter is available with every radius or length combination. OMIST confirms flute finish, обработка поверхности, and cutting geometry according to the actual machining requirement.
4-Flute Standard Series
The confirmed 4-flute series covers cutter diameters of approximately Ø1–Ø20 mm.
Corner radii represented across the series include:
Р0.2 / R0.3 / 0,5 рэнда / R1 / R2
Not every radius is available with every cutter diameter. The table below shows representative confirmed configurations rather than a complete model list.
| D (миллиметр) | R (миллиметр) | ЛОК (миллиметр) | Shank d (миллиметр) | ОАЛ (миллиметр) | Флейты |
|---|---|---|---|---|---|
| 1 | 0.2 | 3 | 4 | 50 | 4F |
| 4 | 0.5 | 10 | 4 | 50 | 4F |
| 6 | 1 | 18 | 6 | 75 | 4F |
| 8 | 1 | 24 | 8 | 75 | 4F |
| 10 | 1 | 30 | 10 | 100 | 4F |
| 12 | 1 | 36 | 12 | 100 | 4F |
| 14 | 2 | 35 | 14 | 100 | 4F |
| 16 | 1 | 40 | 16 | 100 | 4F |
| 20 | 1 | 40 | 20 | 100 | 4F |
Other D, R, ЛОК, хвостовик, and OAL combinations depend on the required tool geometry and machining application.
Стандартные и пользовательские опции
OMIST offers standard 3F and 4F ряд.
For applications outside the standard range, we can manufacture non-standard sizes and geometries. 2F, 5F, 6F, extended-length tools, and other flute configurations are available for custom requirements.
Custom options may include diameter, угловой радиус, ЛОК, ОАЛ, размер хвостовика, счет флейты, спираль, coating or surface treatment, геометрия резки, center-cutting design, и требования к допускам.
Кроме того, выбрано 150 mm OAL configurations are available according to cutter diameter, достигать, и геометрия.
We confirm final manufacturability after reviewing the required dimensions and application.
Применение и выбор
The 3-flute standard series is mainly intended for aluminum and aluminum-alloy machining.
The 4-flute series provides the main standard range for other machining requirements. Для стали, нержавеющая сталь, пресс-форма стали, or hardened-steel applications, OMIST reviews material hardness, размеры инструмента, операция механической обработки, достигать, and cutting conditions before confirming the final configuration.
We also select coating or surface treatment according to the actual application rather than using one fixed specification for the whole product family.
Типичные области применения включают в себя:
- Contour milling
- Профильное фрезерование
- Получистовая обработка
- Отделка
- Обработка пресс-форм и штампов
- Cavity machining
- Pocket machining where a corner radius is acceptable
For applications that require a sharp cutting corner, видеть Бычий нос против фрезы с плоским концом.
For the difference between a flat-bottom radiused cutter and a fully rounded cutting end, видеть Bull Nose vs Ball Nose End Mill.
Corner rounding form cutters are a different tool type used to produce an external workpiece radius. See Угловой радиус против концевой фрезы с закруглением углов.
Ключевые особенности
- Flat Bottom with Corner Radius: Combines a flat cutting end with a defined corner radius.
- Standard 3F and 4F Series: Covers multiple metric diameter, радиус, and length combinations.
- Application-Matched Configuration: Tool geometry and surface treatment depend on the workpiece and machining conditions.
- Изготовление на заказ: Non-standard dimensions, конфигурации флейты, and cutting geometry can be produced from customer requirements or drawings.
Custom Bull Nose End Mill Manufacturing
OMIST supports standard and custom solid carbide bull nose end mills for machining companies, дистрибьюторы, и требования OEM.
Для нестандартных инструментов, we review the required dimensions, геометрия, требование центрирования, and dimensional or radius tolerance against the drawing and machining application.
If a standard size does not fit the part, send the required dimensions, рисунок, образец, or reference image for manufacturability review.
For quotation, please provide the main tool dimensions, материал заготовки, операция механической обработки, и количество. A drawing is preferred for non-standard requirements, but we can also make an initial review from the available dimensions and machining information.
We confirm MOQ, achievable tolerance, and lead time after reviewing the specification and quantity.
Вопросы и ответы
Является ли концевая фреза с закругленным концом такой же, как концевая фреза с угловым радиусом??
For the flat-bottom, radiused-corner geometry covered on this page, “bull nose end mill” is a common market name, while tooling catalogs often use “corner radius end mill.” Confirm the exact tool by its dimensions and geometry.
What flute counts are available?
The standard ranges include a 3-flute aluminum series and a 4-flute series. OMIST can also produce 2F, 5F, 6F, and other flute configurations for custom requirements.
What standard sizes and corner radii are available?
The 3-flute aluminum series covers approximately Ø1–Ø20 mm, с R0.2–R4 across the series.
The confirmed 4-flute range also covers approximately Ø1–Ø20 mm, с Р0.2, R0.3, 0,5 рэнда, R1, and R2 represented across the series.
Actual diameter, радиус, and length combinations vary by tool size and design.
Can custom bull nose end mills be manufactured from a drawing?
Да. OMIST can review non-standard dimensions and geometry from a drawing, необходимые размеры, образец, or machining information.
How should I request a quotation?
Send the main tool dimensions, материал заготовки, операция механической обработки, и количество. For a non-standard tool, include a drawing or reference image when available.
