毛坯工件预压齿

形状配合夹紧的基础

在进行预压齿加工时，毛坯会在进入 CNC 机床前完成夹紧准备。工件通过 LANG 预压齿装置进行预压齿处理，最大可承受 20 吨的压入力。整个过程每个工件仅需 5 秒以内即可完成。预压齿后，工件表面会形成规则、细小且明确的三维凹槽结构，即所谓的预压齿轮廓。夹紧钳口上的齿形结构能够精准啮合该轮廓，从而形成可靠的形状配合连接，实现高稳定性的工件夹紧。

Advantages of the Makro•Grip® stamping technology

High process reliability and reproducibility

No distortion when clamping is released

Maximum holding force with minimal clamping force

No wear on the clamping device / clamping jaws

Reliable even in high-strength materials – enabling stable, form-fit clamping

Consistently high clamping quality

Solutions for Optimal pre-stamping

Not every blank has the same pre-stamping requirements. Depending on the geometry, material, and machining strategy, different stamping units and jaws are used. Makro•Grip® stamping technology offers the right solution for this—flexibly tailored to every application.

Pre-stamping – exactly where you need it

Whether used flexibly at different work places or permanently integrated into a workbench: You decide where the process takes place—we provide the right solution. Pre-stamping your raw parts can be done either on a mobile or stationary basis—tailored to your process requirements. This allows you to design your workflow freely and efficiently.

Stamping jaws are available with regular serration.

Makro•Grip®

Stamping jaws are available with full serration.

Makro•Grip® FS

The right stamping jaws for every material

The choice of stamping jaws depends on the tensile strength and toughness of the material. Two types of serration profiles (Makro•Grip® and Makro•Grip® FS) are available for different material hardnesses up to 35 HRC and up to 45 HRC, respectively. All versions feature quadruple serration and can be easily flipped when worn—ensuring a long service life and high cost-effectiveness.

Designed for various blank geometries

Whether cylindrical or rectangular with parallel surfaces, the stamping technology covers a wide range of parts. The stamping units are intentionally supplied without stamping jaws and can be configured precisely to your requirements—for maximum flexibility in the process.

Scale layer

Saw cut

Versatile – suitable for a wide range of applications

The stamping technology is suitable for all non-brittle materials. It cannot be used, for example, on graphite, fiber-reinforced composites such as carbon, or, in some cases, castings. The pre-stamping is applied directly to the saw cut or the scale layer—additional pre-machining, such as that required for dovetail clamping, is generally not necessary.

五轴加工

以最大夹持力实现安全工件固定

该夹具专为五轴加工中预冲压工件的形状适配夹紧而优化，工件夹持深度仅为3毫米，确保铣削操作期间的最大可达性。

The clamping solution for 5-axis machining

The Makro•Grip® 5-axis vise provides maximum access to the workpiece and creates ideal conditions for 5-axis machining. The combination of the pre-stamped contour and the serrated clamping jaws creates a form-fit connection, generating high holding forces with low clamping pressure. This ensures stable, precise, and reliable machining.

Advantages of the Makro•Grip® 5-Axis Vise

Ideal accessibility for 5-axis machining

Maximum holding force with low clamping pressure

Distortion-free and wear-free clamping

Significant material savings thanks to low clamping edge requirements

Process reliability through consistent clamping quality

Ergonomic handling thanks to low weight

二次加工

通过模块化夹持系统实现灵活性

LANG 模块化夹持系统为二次装夹加工提供了卓越的灵活性。同一虎钳本体可快速搭配多种不同类型的夹紧钳口，并根据具体加工任务进行快速调整，无需更换整套夹紧系统，借助这一模块化设计，工件可高效完成二次装夹加工，在保持原有夹持方案的基础上，实现灵活切换，大幅提升生产效率。

Clamping solutions for second operation machining

For second operation machining, LANG Technik focuses on maximum flexibility: Different jaw versions are fully compatible with a single base body and can be quickly exchanged. This ensures that the right clamping solution is always available—efficient, precise, and reliable.
