BT-ER系列刀柄的优势及适用

新乡弘 BT-ER系列刀柄的核心优势

1. 极致的精密制造与材质

新乡弘深耕刀柄研发定制领域21年，BT-ER系列刀柄采用高强度合金钢（如20CrMoTi等）精工制造，并经过真空淬火与碳氮共渗处理，表面硬度可达56-62度。刀柄本体经高精度研磨，跳动精度（T.I.R.）可严格控制在0.002mm（2μm）以内，确保在高速运转下依然保持卓越的同心度与稳定性。

2. 卓越的动平衡与抗振性能

针对高速切削需求，新乡弘BT-ER系列进行了全系列动平衡设计（支持G2.5级别）。在高速主轴运转下，刀柄能有效吸收并减少切削过程中的振动，大幅降低颤振风险，从而提升工件的表面光洁度并延长刀具使用寿命。

3. 强大的夹持力与防干涉设计

搭配高精度ER筒夹，该系列刀柄具备强劲的夹紧力与出色的密封性能，不仅换刀快准稳，还能有效防止冷却液泄漏。同时，新乡弘提供不同长度及避空设计（如加长型、SLIM超细长型等），完美解决深腔、倒扣等狭小空间加工中的刀柄干涉问题。

4. 灵活的定制与高性价比

依托新乡弘强大的研发实力，除了标准规格外，还可根据客户的个性化需求灵活定制各种型号的高精密刀柄。在提供媲美国际一流品质刀柄的同时，大幅缩短了采购周期，有效降低了企业的综合运营成本。

BT-ER系列刀柄的适用范围

1. 广泛的加工工序

BT-ER系列属于简单适用的通用型刀柄，兼容性极强。通过更换不同规格的筒夹（如ER16, ER20, ER25, ER32, ER40等），可轻松夹持不同直径的直柄刀具，广泛适用于轻至中等载荷的钻孔、铣削、铰孔及攻丝等多种加工操作。

2. 多样化的加工场景

常规批量生产：适用于通用机械开粗、普通模具加工及24小时批量量产，拆装简单，效率极高。

高速精密加工：得益于高精度与动平衡特性，非常适合铝合金高速铣削、新能源电池托盘加工、阀体钻铣及螺纹精加工等场景。

深腔与五轴加工：配合新乡弘的加长或SLIM超细长ER刀柄，可完美胜任塑胶模具深型腔、航空铝合金深框半精铣等复杂工况。

3. 适配多种机床与材质

机床适配：广泛兼容各类立式加工中心、小型台式机及高速雕铣机（BT30/BT40/BT50锥度接口）。

材质加工：适用于碳钢、铸铁、铝合金、模具钢等多种材料的粗加工至半精加工。对于不锈钢等难切削材质，也可通过选配强力型ER筒夹或内冷止水型刀柄来实现稳定加工。

Core Advantages of Xinxiang Hong BT-ER Series Tool Holders

1. Ultimate Precision Manufacturing & Premium Materials

With 21 years of deep expertise in tool holder R&D and customization, Xinxiang Hong manufactures BT-ER series tool holders from high-strength alloy steel (e.g., 20CrMoTi). The material undergoes vacuum quenching and carbonitriding treatment, achieving a surface hardness of 56-62 HRC. The tool holder body is precision-ground to strictly control Total Indicated Runout (T.I.R.) within 0.002mm (2μm), ensuring outstanding concentricity and stability even during high-speed operations.

2. Superior Dynamic Balance & Anti-Vibration Performance

Designed specifically for high-speed cutting, the entire BT-ER series features dynamic balancing (supporting G2.5 grade). During high-speed spindle operation, the tool holder effectively absorbs and minimizes cutting vibrations, significantly reducing the risk of chatter. This enhances the surface finish of the workpiece and extends tool life.

3. Strong Clamping Force & Anti-Interference Design

Paired with high-precision ER collets, this series delivers powerful clamping force and excellent sealing performance. It ensures fast, accurate, and stable tool changes while effectively preventing coolant leakage. Furthermore, Xinxiang Hong offers various lengths and clearance designs (such as extended and SLIM ultra-slim models) to perfectly solve tool holder interference issues in tight spaces, deep cavities, and undercut machining.

4. Flexible Customization & High Cost-Effectiveness

Backed by our robust R&D capabilities, we offer flexible customization for various high-precision tool holders beyond standard specifications. We deliver quality comparable to top international brands while significantly shortening procurement cycles and effectively reducing overall operational costs for our clients.

Application Scope of BT-ER Series Tool Holders

1. Extensive Machining Operations

The BT-ER series is a highly versatile, universal tool holder. By simply changing collets of different specifications (e.g., ER16, ER20, ER25, ER32, ER40), it easily clamps straight-shank tools of various diameters. It is widely used for light to medium-load operations including drilling, milling, reaming, and tapping.

2. Diverse Machining Scenarios

Routine Mass Production: Ideal for general machinery roughing, standard mold machining, and 24-hour continuous production, offering easy tool changes and high efficiency.

High-Speed Precision Machining: Thanks to its high precision and dynamic balance, it is perfect for high-speed aluminum milling, new energy battery tray machining, valve body drilling/milling, and precision thread machining.

Deep Cavity & 5-Axis Machining: When paired with Xinxiang Hong’s extended or SLIM ultra-slim ER tool holders, it effortlessly handles complex tasks such as deep-cavity plastic mold machining and semi-finishing of deep-frame aerospace aluminum parts.

3. Compatibility with Various Machine Tools & Materials

Machine Tool Compatibility: Widely compatible with vertical machining centers, small desktop machines, and high-speed engraving/milling machines (BT30/BT40/BT50 taper interfaces).

Material Machining: Suitable for roughing to semi-finishing of carbon steel, cast iron, aluminum alloys, and mold steels. For difficult-to-cut materials like stainless steel, stable machining can be achieved by selecting heavy-duty ER collets or coolant-sealed tool holders.
