Blades coated with carbide or diamond work best.

Pre-Cut Inspection or Maintenance

Pick your tools and inspect them first. Look for sharpness and check for damage to blades. Prevent debris from affecting performance by cleaning the cutting tools. Properly maintained equipment provides cleaner cuts, keeps your tools working longer.

Methods or Processes to Cut

Here’s how to cut based on the thickness of the sheet:

Cutting Thin Sheets

For thin sheets, use tin snips or hacksaws. For straight cuts, tin snips are perfect whereas hacksaws are for more tight angles. Put your sheet within clamps before begin to cut. Control work slowly and steadily. Make smooth, even strokes to avoid jagged edges.

Cutting Medium Sheets

Quick, straight cuts are possible with angle grinders; jigsaws allow curve cutting. Avoid overheating by using cutting blades designed for stainless steel and taking regular breaks. Mark your cut lines precisely and follow them exactly.

Cutting Thick Sheets

For thick sheets, consider plasma cutters or water jet cutters. High heat is used in plasma cutters to slice quickly through metal. Water jet cutters, however, use pressurized water pumped through the cut with abrasives, keeping the cut pieces cool, while they precisely slice through flesh. Always wear protective gear to guard sparks or debris.

Advanced cutting

Detailed patterns are best cut with laser cutters. These tools are unsurpassed in accuracy for complex designs. Find a speed and power setting for clean cut without scorch. Try your settings with scrap material before tackling your project.

Handling Post Cutting Edges

File and deburr edges to smooth finish after cutting. Remove sharpness with metal files or deburring tools. It is important to wear gloves at all times when working with edges. Wipe down the sheet for safety in case any of the remaining metal shards are stuck to the sheet.

Safety Measures for Cutting Sheets

To ensure a secure and safe process, follow these precautions.

Wear PPE

The safer thing to do is to wear safety glasses when working in areas of flying debris. Wear durable gloves to protect hands from sharp edges.
