aluminum castings in the three-dimensional detection equipment industry
Aluminum castings for coordinate measuring machine (CMM).
Aluminum castings are widely used for CMM (Coordinate Measuring Machine) structural parts, including beams, Z-slides, worktable bases and support frames.
Features: high specific stiffness, light weight, good thermal conductivity, integrated complex structure by casting. Reduce moving inertia, improve dynamic performance and measuring stability. Material: A356-T6 aluminum alloy. Strict stress relief & inspection to guarantee long-term dimensional stability for precision metrology equipment.
Application scenarios and core components of aluminum castings
Three coordinate measuring machines (CMM) have high requirements for lightweight, high rigidity, low thermal deformation, and shock absorption. Aluminum alloy castings are the preferred core structural components, and the main casting parts are:
1. Workbench base
Large gantry style three coordinate base, mostly made of cast aluminum (mainly A356). Compared to cast iron, it has significantly reduced weight, making it easier to transport and assemble; Casting integrated molding reduces splicing and ensures benchmark flatness. Small and medium-sized bridge type three coordinate systems are widely used.
2. Cross beam (Y-axis main beam)
The most critical moving component. The cast aluminum crossbeam balances high stiffness and low density, reducing motion inertia and improving measurement speed and dynamic stability; Reduce driving load, lower motor energy consumption, suppress vibration during high-speed movement, and improve measurement accuracy.
3. Z-axis slide/carriage, column
A moving frame that drives the probe to move up and down. Aluminum castings can be cast as a whole, which can directly produce installation bosses, rib plates, oil/cable troughs, reducing machining workload; Reduce weight, lower rail load, and improve responsiveness.
4. Test seat bracket, adapter shell, and outer casing
Fixed bracket for measuring head, protective shell for grating ruler, and base for electrical control box. Utilizing the characteristic of aluminum casting that is easy to form complex inner cavities, an integrated heat dissipation structure is utilized; Aluminum alloy has good thermal conductivity, which is conducive to heat dissipation of electrical components.
5. Auxiliary structural components:
connecting supports, counterweights, protective cover frames
