Introduction
Gantry Machining Center GL28 Series refers to the large-scale machining center in which the Z-axis axis of the spindle is perpendicular to the worktable, especially suitable for machining large workpieces and workpieces with complex shapes. Its overall structure is composed of double columns and roof beams, which is a portal structure. All the process, process parameters, and displacement data can be used to control the processing of the machine tool after being compiled into a program. Its processing size accuracy is between 0.005 and 0.01 mm, which is not affected by the complexity of the parts. Since most operations are automated by machines, human error is eliminated and batch size consistency is improved.
Features
1. The machine tools and columns of Gantry Machining Center GL28 Series are cast from ultra-high-performance concrete, so the overall structure is highly rigid, and the thermal conductivity is also low, making it more complete during operation.
2. Moving parts are lighter, so there is the less potential energy of inertia and the machine responds more quickly.
3. Large-area sliders and heavy-duty roller rails have good support capabilities and can achieve strong cutting
4. The Z-axis of Gantry Machining Center GL28 Series adopts double balance cylinders, so the unbalance caused by self-weight can be taken care of.
