Top Problems Metal Workers Face When Cutting Metal
Metal workers rely on cutting tools like circular saws to make accurate and efficient cuts, but face a few common challenges in their work. Understanding the most frequent issues when cutting metal can help workers anticipate and address them.
Inaccurate Cuts
One of the top frustrations metal workers encounter is cuts that are inaccurate or uneven. Some typical causes include:
- Worn out or damaged blades
- Wrong blade for the metal type
- Moving or shaking during the cut
- Uneven downward force applied
Checking that blades are sharp and undamaged before starting helps avoid ragged cuts. Referencing blade specification charts to match the right blade teeth design for the metal material is also important.
Slow Cutting Speeds
Cutting metal can be time consuming, especially thick pieces. Factors contributing to slow speeds include:
- Insufficient saw power/RPM
- Blades needing sharpening
- Coolant sprayers not working properly
- Feed rate too slow
Choosing saws with higher horsepower and RPM ranges helps conquer thick, hard metals. Sharpening or replacing dull blades regularly maintains cutting performance. Effective coolant use prevents overheating.
Overheating Blades
Friction during metal cutting generates intense heat. Overheating problems typically stem from:
- Cutting too quickly
- Insufficient coolant
- Dull blades needing sharpening
- Blade/saw size too small for the cut
Monitoring feed rates, using adequate coolant, and sharpening or swapping blades at the first sign of overheating prevents damage. Oversized saws spread the heat over larger surface areas as well.
Burring and Rough Edges
Molten metal remnants around cut edgesrequire additional work to smooth out. Burring occurs due to:
- Excessive feed rate speed
- Worn blades
- Blade designed for cross-cutting used on a rip cut
- Dull blade teeth
Using the proper blade designs and sizes, maintaining sharp blade teeth, and controlling feed rate helps prevent burring. Deburring tools can quickly smooth rough edges too.
Safety Hazards
Cutting metal carries numerous safety risks like injuries from sharp objects, sparks, and debris. Dangerous situations include:
- Not wearing correct PPE like eye/face protection
- Poor saw blade guards or missing guards
- Attempting manual cuts without proper tools
- Distractions or fatigue resulting in lapses of focus
Staying alert, donning appropriate protective equipment, keeping blade guards in working order, and using right tools for each task minimizes safety incidents when cutting metal.
Most Important Features of a Good Metal Cutting Saw
When selecting a metal cutting saw, workers need to consider certain features and capabilities to ensure the saw can handle the demands of metal fabrication work. Here are some of the most important factors to look for in a high-quality metal cutting saw:
Motor Power
The motor directly influences cutting performance. Higher amperage ratings and horsepower allow the blade to spin at faster RPMs and make smoother, faster cuts through thick or hard metal. Look for:
- At least 10-15 amps
- Horsepower of 3 or higher
- No-load speeds of 4000-5000 RPM
Cutting Depth
Max cutting depth determines the thickness of metal the saw blade can penetrate in a single pass. For metal workers, look for depth capacities of:
- 2 inches for portable saws
- 5 inches or greater for stationary band saws
Blade Size
The diameter of the blade also impacts cutting power and depth. Wider blades can cut thicker metal in one pass. Consider these ideal blade sizes:
- 7-1/4 to 10 inches for portable circular saws
- 14 inches or larger for stationary metal cutting band saws
Adjustable Blade Speeds
The ability to adjust blade speed allows matching the RPM to the metal material for optimal performance. Lower RPMs are used on thinner sheets, while harder metals require faster speeds.
Blade Types
Using the right blade design for the metal and cut type improves cutting efficiency and accuracy. Look for saws that accept these interchangeable blade types:
- Abrasive blades for stainless, non-ferrous metals
- Standard blades for mild steel
- Carbide-tipped for hardened steels
Cooling System
Built-in coolant pumps extend blade life by preventing overheating. Look for flood coolant systems that run a constant stream of coolant to the blade.
Safety Features
Metal cutting saws contain hazards like fast spinning blades and sparks. Seek models with these safety additions:
- Completely enclosed blade guards
- Blade brakes to quickly stop the blade
- Thermal overload protection
- Non-slip base pads
When armed with the knowledge of the most vital metal cutting saw capabilities, workers can find the right saw to help them work safely, efficiently, and productively.
