适用于各种应用的最佳夹紧工具

在刀具使用中，与机床主轴的连接技术， 亦即夹紧技术，扮演着一个核心的角色， 但是，也往往被忽视。
在零件的精密加工中，刀具必须要达到极 高的径向跳动精度。即使在钻孔和铣削加 工中，对加工也有非常大的影响，径向误 差小，对刀具寿命会产生正面的影响。
 
概述 MAPAL 的夹具类型和技术。
采用最先进的技术生产制造的 MAPAL 夹 紧产品为每种应用都提供有最完美的解决 方案，由此而形成了最佳的连接，保证了 刀具应用中所要求的高性能、高径向跳动 精度和高更换精度。
​​​​​​​从配置 MAPAL KS 卡 夹的手动 HSK 夹紧单元，到带法兰刀柄的夹紧工具，从液压刀柄、热涨刀柄到转 接柄，应有尽有，MAPAL 标准产品包含了 极为广泛的系统和技术。
MAPAL 也为采用 油雾润滑的加工提供有大量的标准产品。

    手动 HSK 夹紧技术

    MAPAL HSK 夹紧技术的一个重要组成部分 就是 KS 卡夹。
    手动夹紧机构由于其简单 且坚实的结构而具有极高的拉紧力和夹紧 力。
    ​​​​​​​KS 卡夹可以直接应用在主轴夹头和 基础夹头中，或者通过夹紧法兰应用。

  • 不同类型的液压卡盘

    液压涨紧技术

    由于其高径向跳动精度以及由此带来的均匀切削，以及优秀的 减振特性，MAPAL 液压刀柄 HydroChuck 保证了最佳的工件表面 质量。
    另外，由于液压系统也防止了刀片的微小破坏，从而提 高了使用寿命和降低了成本。
    即使在高转速时也保证了很高的 夹紧安全性。
    既可以轴向，也可以径向对刀柄进行 μ 级精度的 长度调整。
    ​​​​​​​在标准产品目录中，提供有油雾润滑款式，以及短 重型和超短型带长锥度的款式供使用。

    Shrink chucks

    Using the shrink chucks ThermoChuck the tools can be accurately clamped for almost all milling operations. High torque transmission and radial rigidity characterise this chuck. Long-term radial run-out accuracy and repetition accuracy of < 3 μm in the location bore guarantee high dimensional accuracy at the workpiece. The shrink chucks from MAPAL are finely balanced as standard so that high surface finishes and long tool lives are ensured.

    Mechanical chucks

    Mechanical chucks impress due to their simple construction and the uncomplicated handling. The clamping is safeguarded regardless of the direction of rotation even at high spindle speeds. The standard programme for mechanical tool clamping covers precision drill chucks that are also available in a micro design with direct clamping from 0.2 mm. Due to the modular design, the drill chucks are available with all forms of machine-side tool bodies. Collet chucks, Weldon and Whistle Notch chucks round off the programme of mechanical chucks.

    Power chucks for high-performance milling operations

    MAPAL's power chuck impresses with its strong clamping capacity, easy handling and significantly improved radial run-out. The location bore is manufactured in the single digit μm range and therefore with significantly more precision than before. This reduces the radial play of the clamped tool and significantly improves radial run-out. The large tolerance on the lateral clamping surface is also compensated. Here MAPAL relies on a spring element in the connection that makes possible a defined form closure between tool and connection. Cooling channels parallel to the axis in the clamping range also ensure improved coolant supply. To simplify the handling, a two-piece clamping element is used. This reduces the tightening torque while maintaining the same clamping force, enabling the tool to be reliably clamped in the connection manually.

Various chucks suitable for minimum quantity lubrication machining

Broad standard programme of MQL clamping tools

An important role for a stable MQL process is played by the related chuck so that the lubricating medium is reliably transported to the cutting edge. MAPAL offers clamping tools for the 1-channel system and also for the 2-channel system. From shrink chucks of short and long design, through hydraulic chucks with axial or radial length adjustment, to the HighTorque Chuck (HTC). The advantages of the HTC are above all extremely high torque transmission for high-power milling and extremely good thermal stability. This aspect is particularly important, as during MQL machining relatively high temperatures reach the chuck via the tool shank.
