Masterpiece in the world # 2
Centering vise optimal for 5-axis machines to achieve high-speed and stable machining of varieties of materials and shapes with high accuracy and rigidity.

There has been an increasing number of customers who use 5-axis machines to achieve highly efficient machining of complex-shaped and difficult-to-cut materials. Highly efficient machining requires workpiece centering and quick setup changes of workpieces with different shapes, but high-accuracy setting of vises takes time in some cases.

A lack of vise rigidity can lead to substandard machining accuracy when workpieces with a high degree of hardness are machined, so it is important to reduce gripper margins as small as possible and to effectively use costly materials. To handle such challenging issues, we introduce the “MC-PZ,” a centering vise for 5-axis machining centers developed by Hilma of Germany.

Shorter production time by high-accuracy centering and easy attachment/detachment

The “MC-PZ” centers workpieces to be clamped. It reduces traveling time of tools and tables, and increases actual machining time. When changing finished workpieces together with the vise, attach one-touch jaws to the bottom of the vise and set the device to fix the jaws on the machine side for a quick change.

Mousepiece changing function and high-rigidity performance ensure machining of high-hardness and difficult-to-cut materials with stable accuracy

The product can hold workpieces appropriately as the body made of steel ensures sufficient rigidity to minimize warping of workpieces when they are clamped.

In addition, the driving unit is sealed up so that no chips enter the unit. This prevents decrease in accuracy by disturbance, and stabilizes centering of workpiece. The high rigidity enables machining of difficult-to-cut materials such as titanium and Inconel.

Mousepieces to clamp workpieces can be changed depending on materials. As the customization is possible, one unit can handle various materials of workpieces.

High-accuracy machining with less waste of costly materials by a smallest gripper margin

For those who use titanium for aircraft components, an effective use of the material has always been a challenging issue. Some customers successfully reduced up to 20% of titanium waste by employing the product. The vise they had used before requires a gripper margin of 20 mm, and the margin needs to be discarded after machining. The product, on the other hand, needs only 3 to 5 mm margin for clamping, which can reduce waste and ensure stable accuracy with no chatter.

There has been an increasing number of customers who had shifted from 3-axis machines to 5-axis machines in recent years. When used with the high-performance vise, 5-axis machines can maximize the capabilities. The “MC-PZ” exclusively designed for 5-axis machines enables an effective use of 5-axis machines and efficient machining of difficult-to-cut materials.
