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, 직선 측벽, 슬롯, 주머니, 단계, 그리고 스퀘어어깨. 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. 게다가, we can evaluate custom cutting diameters, 플루트 길이, 전체 길이, 생크 크기, 플루트 카운트, 초경 재종, 코팅, and tolerances according to your drawing and machining requirements.

주요 특징

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. 그러므로, it suits components that require flat-bottom slots, square pockets, 직선 벽, 단계, or near-90-degree shoulders.

Sharp corners carry more cutting stress than rounded corners. 이러한 이유로, 탄화물 등급, 가장자리 준비, 코팅, 도구 돌출부, and cutting parameters should match the workpiece material and machining conditions.

솔리드 카바이드 구조

솔리드 카바이드는 우수한 강성을 제공합니다., 내마모성, 및 치수 안정성. It also supports precise flute geometry and sharp cutting edges.

결과적으로, the tool can maintain accuracy during slotting, 주머니에 넣는, 사이드 밀링, 숄더 밀링, 그리고 마무리. 하지만, 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, 공구 강성, cutting efficiency, 및 표면 마무리.

둘- and three-flute designs provide more chip space. 그러므로, they often suit aluminum, 구리, 플라스틱, 부드러운 소재, 깊은 슬롯, and applications that create a large volume of chips.

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

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

코팅 및 비코팅 옵션

Uncoated or polished cutting edges often suit aluminum, 구리, 기타 비철재료. These options can help reduce material adhesion and built-up edges.

Coated tools can improve heat resistance and wear resistance when machining steel, 스테인레스 스틸, 주철, 합금강, and harder materials. The final coating should match the workpiece material, 경도, 냉각수 상태, 및 가공작업.

Application Guide

See the main flat end mill applications in CNC machining, including slotting, 주머니에 넣는, 사이드 밀링, 숄더 밀링, and entry methods.

알루미늄용, 부드러운 소재, and deep slots, fewer flutes usually provide better chip evacuation. 우리의 검토 2 플루트 엔드밀 for these applications.

For a detailed guide to slotting, 주머니에 넣는, 사이드 밀링, 숄더 밀링, plunging, and entry methods, read about flat end mill applications in CNC machining.

철강용, 스테인레스 스틸, 일반 CNC 밀링, a four-flute design often provides a practical balance between rigidity, 최첨단 강도, 그리고 칩 컨트롤. 우리의 검토 4 플루트 엔드밀.

사이드 밀링용, 준결승, 그리고 마무리, a six-flute design can improve stability and surface quality. 하지만, it offers less chip space and is not usually the first choice for heavy slotting. 우리를 참조하십시오 6 플루트 엔드밀.

Choosing by Workpiece Material

The final recommendation depends on the material grade, 경도, 절단 폭, 절단 깊이, 냉각수 상태, 기계 강성, 그리고 필요한 표면 마감. 그러므로, 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, 램핑, 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. 그러므로, please tell us whether the tool will enter by vertical plunging, 램핑, 측면 입장, or an existing hole.

Flat End Mill vs Other End Profiles

불 노즈 vs 플랫 엔드밀

A flat end mill has sharp corners for square shoulders and flat-bottom features. 대조적으로, 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. 하지만, they cannot produce the same sharp internal corner as a flat end profile.

Read the complete 불 노즈 vs 플랫 엔드밀 comparison before selecting the end profile.

For parts that require stronger corners or a specified corner radius, 우리의 검토 불 노즈 엔드밀.

Ball Nose vs Flat End Mill

A ball nose end mill has a fully rounded cutting end for molds, 죽는다, 곡면, and three-dimensional contours.

In comparison, a flat end profile is better suited to slots, 주머니, 직선 벽, 평평한 표면, 그리고 스퀘어어깨. For curved and three-dimensional machining, 우리의 검토 볼 노즈 엔드밀.

자주 묻는 질문

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. 하지만, 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, 램핑, 또는 나선형 입구. 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, 부드러운 소재, and deep slots. 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?

예. We can evaluate custom diameters, 플루트 길이, 전체 길이, 생크 크기, 플루트 카운트, 코팅, and tolerances according to your drawing and machining requirements.
