Applications of VMC 4th axis bridge broad
The 4th axis bridge broad generally refers to a machine tool accessory or structural support assembly used to mount a 4th axis (rotary axis), thereby expanding a three-axis machining center to 4th axis machining capability. The bridge plate can also be understood as a mounting platform connecting the four axes to the 4th axis tailstock, providing ample fixture expansion capabilities for the four axes.
Typical applications of four-axis bridge plates include home appliance parts, automotive parts, hardware parts, and aerospace. They offer significant advantages, particularly for the mass production of complex parts, reducing the number of clamping operations or increasing the number of clamps. Below are some examples illustrating the application range of 4th axis bridge broad.
1. 4th axis bridge broad zero-point positioning fixture
The mounting base module is fixed on the 4th axis bridge broad , and the positioning pin is installed on the workpiece, mold or fixture . When the workpiece is placed in the base, the locking mechanism is driven by air pressure or mechanical spring, and the ball claw /locking pin enters the positioning cone hole to automatically complete "positioning + clamping".
When the air pressure is released, the spring or air pressure is released in the opposite direction, enabling quick replacement.
This four-axis bridge broad clamp has the following advantages:
•Quickly change fixtures and workpieces to improve machine tool uptime.
•High repeatability and reduced recalibration time.
4th axis bridge broad fixture is suitable for single medium-to-large parts that require multi-face machining. By rotating or linking the fourth axis, multi-face machining can be completed in one clamping , reducing the impact on accuracy caused by multiple clamping. This type of 4thaxis bridge broad fixture is usually paired with machine tools with a large-stroke spindle with rich tool extension capabilities and powerful cutting capabilities, such as JIAKUN VMC vertical machining centers.
2. 4th axis bridge broad multi-station vise
The 4th axis bridge broad multi-station vise is a vise base with two or more sets of clamping units (usually 2 to 8 stations) that can clamp multiple workpieces at once, realizing multi-piece processing on one machine .
This 4th axis bridge broad clamp has the following advantages:
•High-rigidity integral base design to prevent deformation.
•Highly compatible and widely applicable.
•High efficiency, multiple workpieces can be clamped at once, reducing the number of workpiece changes.
3. Customized four-axis bridge broad fixture
Custom-designed fixtures are clamping devices tailored to specific workpieces, processes, or machine tool conditions. Unlike standard fixtures such as general-purpose vises or chucks, they are tooling specifically developed based on workpiece shape, machining requirements, and process routes.
The four-axis bridge plate custom clamp has the following advantages:
•High clamping efficiency.
•Easy to operate, replace parts, and test.
•Compact structure, unified benchmark.
