Japanese CNMG 刀片座
CNMG 刀片刀把是一種廣泛使用的車削刀把，專門用來穩固夾持 CNMG 型可轉位刀片。根據 ISO 標準，"CNMG "是指菱形刀片，具有 80 度的刀尖角、間隙角、中性切削動作及中央安裝孔。這些刀片具有高度的通用性，通常用於鋼材、不銹鋼及鑄鐵等多種材質的中到重切削粗加工及半精加工。
CNMG刀片刀座的主要功能是為CNMG刀片提供堅固且穩定的平台。這可確保精確的材料去除率、良好的切屑控制及最佳的表面光潔度。刀把具有精密加工的刀槽，與CNMG刀片的形狀與尺寸完全吻合，可安全且可重複夾持。通常會使用螺絲或槓桿機構來固定刀片，即使在強大的切削力下，也能防止加工過程中任何不必要的移動或震動。
CNMG刀片因其強韌的切削刃及每片刀片有四個切削刃（每邊兩個），提供極佳的刀具壽命及成本效益而廣受歡迎。相應的CNMG刀片刀把設計使用方便，可快速有效地進行刀片分度或更換，從而減少機器停機時間。這些刀把有多種刀柄尺寸與配置，可適用於不同的機床類型與加工應用。選擇 CNMG 刀片刀把時，請考慮以下需求 CNMG 刀片座規格 例如刀柄尺寸和導角，對於最佳性能至關重要。
常見問題
"CNMG "是 ISO 標誌，表示特定的菱形 (80 度) 切削刀片，具有間隙角及中性切削動作。
它可夾持 CNMG 型可轉換式切削刀片，刀片呈菱形，刀尖角度為 80 度。
可在各種材料上進行中型至重型粗加工和半精加工。
切削刃強韌，每個刀片有四個切削刃，切屑控制良好，適用於各種材料。
考慮機床所需的刀柄尺寸、車削作業類型、加工材料以及所需的前角。檢查 CNMG 刀片座規格 在此非常重要。
常見尺寸包括 1/2 吋、5/8 吋、3/4 吋、1 吋，以及公制等效尺寸，適用於各種機床刀把。
是的，只要有適當的 CNMG 刀片等級與幾何形狀，就可以用於半精加工，甚至某些精加工應用。
Rigidity, secure clamping, precise insert pocket, and compatibility with your machine and inserts. Reviewing the CNMG 刀片座規格 will help.
Yes, holders are available with various lead angles to optimize performance for different turning tasks.
CNMG 刀片座規格
- Shank Size (System Designation): This refers to the dimensions of the tool holder’s shank that fits into the machine tool’s turret or tool post. Common shank sizes are given in inches (e.g., 1/2″, 5/8″, 3/4″, 1″) or millimeters (e.g., 12mm, 16mm, 20mm, 25mm). This is crucial for compatibility with your machine.
- Overall Length: The total length of the tool holder, which can be important for clearance and reach in certain machining setups.
- Insert Size Designation: Specifies the exact size and geometry of the CNMG insert that the holder is designed to accommodate. For example, you might see specifications like “for CNMG120404”, where “12” refers to the cutting edge length, “04” to the thickness, and “04” to the nose radius (in this example, following a common interpretation). Different CNMG insert sizes will require different tool holders.
- Lead Angle (Cutting Edge Angle): This is the angle between the cutting edge of the insert and the direction of feed. Different lead angles are suitable for various turning operations, such as facing, shouldering, or general turning. Common lead angles for CNMG holders might be 0 degrees, 5 degrees, or others.
- Cutting Direction (Hand): Indicates whether the tool holder is designed for right-hand or left-hand cutting. This determines the direction in which the tool can be fed along the workpiece.
- Coolant Supply: Specifies whether the tool holder has internal coolant channels that direct coolant to the cutting zone. This is beneficial for chip evacuation, reducing cutting temperatures, and improving tool life. You might see designations like “with internal coolant” or “without internal coolant.”
- Clamping System: Describes the method used to secure the CNMG insert in the holder. Common clamping systems include screw-on, lever lock, or wedge clamp.
- Tool Style/Designation: Manufacturers often have their own specific coding systems or model numbers that further define the tool holder’s characteristics and intended use.
- 材質： The material from which the tool holder is made, typically a high-strength alloy steel for durability and rigidity.
- 塗層： Some tool holders may have surface coatings to enhance wear resistance, reduce friction, or improve performance in specific materials.
- Manufacturer: The company that produces the tool holder.
