Solid Carbide Flat End Mill for CNC Machining

A flat end mill has a flat cutting end and sharp outer corners. It produces flat-bottom features, straight side walls, слоты, карманы, шаги, and square shoulders. Many buyers also use the term square end mill for the same general end profile.

We supply solid carbide flat end mills in standard metric and inch sizes. Кроме того, we can evaluate custom cutting diameters, длина канавок, overall lengths, shank sizes, Количество флейт, carbide grades, покрытия, and tolerances according to your drawing and machining requirements.

Ключевые особенности

Flat Bottom and Sharp Cutting Corners

The flat end profile creates a level bottom surface and a clear transition between the bottom and side wall. Поэтому, it suits components that require flat-bottom slots, square pockets, straight walls, шаги, or near-90-degree shoulders.

Sharp corners carry more cutting stress than rounded corners. По этой причине, the carbide grade, edge preparation, покрытие, tool overhang, and cutting parameters should match the workpiece material and machining conditions.

Твердосплавная конструкция

Solid carbide provides good rigidity, износостойкость, и стабильность размеров. It also supports precise flute geometry and sharp cutting edges.

Как результат, the tool can maintain accuracy during slotting, pocketing, боковое фрезерование, фрезерование уступов, и отделка. Однако, a rigid machine setup and short tool overhang help reduce vibration and corner damage.

Multiple Flute Options

Different flute counts provide different balances between chip space, жесткость инструмента, эффективность резки, и качество поверхности.

Two- and three-flute designs provide more chip space. Поэтому, they often suit aluminum, медь, Пластмасс, мягкие материалы, deep slots, and applications that create a large volume of chips.

Four-flute designs provide more cutting edges and greater rigidity. They suit many steel, нержавеющая сталь, and general CNC machining applications.

Six-flute designs can improve cutting stability and surface quality during side milling and finishing. Однако, they provide less chip space and are not usually the first choice for heavy full-width slotting.

Coated and Uncoated Options

Uncoated or polished cutting edges often suit aluminum, медь, и другие цветные материалы. These options can help reduce material adhesion and built-up edges.

Coated tools can improve heat resistance and wear resistance when machining steel, нержавеющая сталь, чугун, легированная сталь, and harder materials. The final coating should match the workpiece material, твердость, coolant condition, и операции механической обработки.

Application Guide

See the main flat end mill applications in CNC machining, including slotting, pocketing, боковое фрезерование, фрезерование уступов, and entry methods.

Для алюминия, мягкие материалы, и глубокие слоты, fewer flutes usually provide better chip evacuation. Review our 2 концевая фреза с канавками for these applications.

For a detailed guide to slotting, pocketing, боковое фрезерование, фрезерование уступов, plunging, and entry methods, read about flat end mill applications in CNC machining.

Для стали, нержавеющая сталь, и общее фрезерование с ЧПУ, a four-flute design often provides a practical balance between rigidity, cutting-edge strength, and chip control. Review our 4 концевая фреза с канавками.

For side milling, получистовая обработка, и отделка, a six-flute design can improve stability and surface quality. Однако, it offers less chip space and is not usually the first choice for heavy slotting. See our 6 концевая фреза с канавками.

Choosing by Workpiece Material

The final recommendation depends on the material grade, твердость, cutting width, глубина резания, coolant condition, жесткость машины, и требуемая обработка поверхности. Поэтому, please provide the exact workpiece material and hardness when requesting a quotation.

Center-Cutting and Entry Methods

Entry capability depends on the exact end-cutting geometry and tool design. Some flat end mills support controlled plunging, ramping, or helical interpolation, while other designs require side entry or an existing hole.

Ramping or helical entry usually reduces cutting shock and improves chip evacuation. Поэтому, please tell us whether the tool will enter by vertical plunging, ramping, side entry, or an existing hole.

• Metric or inch cutting diameter
• Стандартный, short, long, or custom flute length
• Standard or custom overall length
• Standard or custom shank diameter
• Neck diameter and neck length
• 2, 3, 4, 6, or custom flute count
• Center-cutting geometry
• Standard or custom helix angle
• Sharp or prepared cutting edge
• Без покрытия, polished, or application-specific coating
• Dimensional tolerance according to the drawing

Flat End Mill vs Other End Profiles

Бычий нос против фрезы с плоским концом

A flat end mill has sharp corners for square shoulders and flat-bottom features. В отличие, a bull nose end mill keeps a flat center section but adds corner radii.

The radii strengthen the cutting corners and create a smoother transition between the bottom and side wall. Однако, they cannot produce the same sharp internal corner as a flat end profile.

Read the complete бычий нос против фрезы с плоским концом comparison before selecting the end profile.

For parts that require stronger corners or a specified corner radius, review our Концевая фреза с бычьим носом.

Ball Nose vs Flat End Mill

A ball nose end mill has a fully rounded cutting end for molds, умирает, изогнутые поверхности, and three-dimensional contours.

In comparison, a flat end profile is better suited to slots, карманы, straight walls, flat surfaces, and square shoulders. For curved and three-dimensional machining, review our концевые фрезы со сферическим концом.

Часто задаваемые вопросы

Is a flat end mill the same as a square end mill?

In many cutting tool catalogs, flat end mill and square end mill describe the same general end profile: a flat cutting end with sharp outer corners. Однако, naming may vary between manufacturers and markets.

Can a flat end mill plunge into solid material?

A center-cutting flat end mill can perform controlled plunging, ramping, or helical entry. A non-center-cutting tool cannot plunge vertically into solid material.

Which flute count should I choose?

Two or three flutes provide more chip space for aluminum, мягкие материалы, и глубокие слоты. Four flutes suit many steel and general machining applications, while six flutes work well for stable side milling and finishing.

Can you manufacture custom flat end mills?

Да. We can evaluate custom diameters, длина канавок, overall lengths, shank sizes, Количество флейт, покрытия, and tolerances according to your drawing and machining requirements.
