Choosing the Right CNC Cutting Method
Cnc Laser Cutting
A continuous cut is produced by moving a CO₂, YAG, or fiber powered laser cutting head over the work piece with the use of a CNC gantry system. Laser cutting is great for production quantity
Related Materials: Steel, Aluminum, Stainless Steel, Plywood, & Acrylic.
Strength: Excellent cut edge quality & can cut a wide variety of materials.
Weakness: More expensive than plasma cutting & not capable of cutting thick metals.
Cnc Plasma Cutting
When prototyping quickly and on a budget, CNC plasma cutting is the best option. Cuts can be made in a wide array of materials, including stainless steel, aluminium, mild steel, and more. The speed of plasma cutting also makes it ideal for large pieces, extended jobs, and production run parts.
Weakness: Less accuracy compared to laser or waterjet & larger heat affected zone.
Related Materials: Steel, Aluminum, Stainless Steel, Brass, & Copper.
Strength: Most affordable cutting method with quick processing times.
Cnc Waterjet Cutting
Waterjet cutting uses an ultra-high pressure stream of water to carry an abrasive grit. The abrasive cutting leaves a precise, smooth cut surface. Waterjet is the most versatile process, because it is able to cut almost any material; however, it is a very slow and time consuming process.
Weakness: Slow production time & more costly compared to other cutting methods.
Related Materials: Metals, Plastics, Ceramics, & virtually any material except Tempered Glass.
Strength: Ability to cut almost any material with quality finish & no heat affected zone.
