Hey it s justin let s talk about routing aluminum.
Cnc machined holes aluminum sheet.
Laser engraver cnc laser engraving cutting machine diy laser marking for metal with 32 bit motherboard lasergrbl.
Our production capabilities for machining powered by our new hampshire based facility rapid manufacturing allow up to 1 000 machined parts along with first article inspection fai reporting material certifications part assembly and additional finishing options like anodizing and.
We ve done a handful of aluminum projects on our machine but this was the big kahuna.
Xometry recommends staying above 14 gauge for best performance and designing with common gauge thickness.
Perforated metal is any type of sheet metal that has a pattern of holes punched into it.
The process can create a hole with a single millisecond thousandth of a second pulse of the electron beam and the workpiece and beam move relative to each other making possible extraordinary hole making rates.
Cnc routers use a variety of specialized cutters that should not be used with aluminum.
Let s go through what we learned.
Stocked perforated sheet metal.
Hole making is a class of machining operations that are specifically used to cut a hole into a workpiece machining a material removal process creates features on a part by cutting away the unwanted material and requires a machine workpiece fixture and cutting tool hole making can be performed on a variety of machines including general machining equipment such as cnc milling machines or.
This makes it useful for controlling the passage of air light liquids and even sound.
Most of the cnc world uses 2 or 3 flute carbide endmills for the purpose.
Six sheets of 0 5 inch thick 6061.
Sheet metal 0 010 0 020 is typical and highly dependent on geometric features like bends and weldments.
For example a hole that can be machined on a vertical mill at one tolerance range may need to be bored on a lathe in a tighter tolerance range adding set up costs and lead time.
Including cnc machining 3d printing sheet metal metal stamping die casting extrusion urethane casting and injection molding.
Perforated sheet metal is most commonly used for ventilation and filtering.
For example 100 micrometer diameter holes can be drilled in 0 3 mm thick sheet at 1 500 to 2 000 holes per second.
Downcut spirals compression cutters and the like have no place in aluminum work.
This project has been in the works for months and it felt really great to finally make a bunch of chips.
You want cutters specifically made for aluminum.
Reduce your cnc machining costs when you order higher quantities of machined parts.
