Cutting Aluminium on a Saw: PCD Blade Specifications That Work
Aluminium cuts differently from wood: heat, gumming and chip welding. How to specify a PCD blade for profiles, extrusions and plate.
Technical notes
Notes from the shop floor: which tooth geometry suits which panel, how a worn edge reads before it fails, and what to measure before ordering a replacement blade.
Aluminium cuts differently from wood: heat, gumming and chip welding. How to specify a PCD blade for profiles, extrusions and plate.
Tooth geometry is only as good as the grinding behind it. How laser and conventional grinding differ in accuracy, consistency and tooth life.
Suppliers claim any tooth type is possible. What that really means, what to specify, and how custom profiles affect lead time and cost.
Buying blades from an overseas manufacturer? How shipping methods, Incoterms, duties and lead times actually work - and how to plan around them.
How to inspect a blade shipment: what to measure, what to check visually, and what to do when a batch does not match the specification.
What actually happens between sending a drawing and receiving blades: engineering review, first article, production and acceptance explained step by step.
PCD tipping, stepped tooth profiles, laser grinding and thinner plates: the four technology shifts changing how panel cutting lines are specified.
The three numbers on a blade spec that decide cut width, stiffness and tip support - and how to read them on a diagram without guessing.
Blade life is decided as much between cuts as during them. How to clean, store and transport saw blades so they stay accurate and safe.
