SHAPING METAL, CRAFTING EXCELLENCE
Burring refers to the small raised edges and imperfections that remain on a material after it has been modified through processes like cutting, countersinking, and tapping. The removal of these imperfections is known as deburring.
We recognize that some customers may prefer not to have their materials deburred for various reasons. If that’s the case, please specify this in your order or the drawings you provide. Our deburring services are exceptional, allowing us to address any potential imperfections with a high level of professionalism.
We utilize a range of deburring equipment, with our standout tool being the automatic deburring machine. This machine features eight large brushes that rotate in different directions to ensure thorough deburring of all surfaces. Thanks to this automation, we can achieve a more consistent finish compared to handheld deburring methods. We also maintain multiple sets of brushes to prevent cross-contamination between stainless steel and mild steel parts.
Unlike many competitors’ equipment, our automatic deburring machine can treat parts from all angles equally. Standard machines typically hit parts from only one direction, requiring multiple passes, which increases both time and cost.
For additional deburring, we employ our industrial rumbling machine (or ‘rumbler’). This machine is filled with smooth ceramic stones that aggressively vibrate with the metallic components inside. This action mimics the natural erosion of ocean waves, gently wearing away a small amount of the surface and edges of the components without affecting tolerances, effectively removing sharp edges and defects. This is especially beneficial for those requiring a flawless finish.
Another advantage of our equipment is the ability to deburr the top side of polished materials while preserving the plastic coating, or we can set a grain direction to ensure the DP1 face remains undamaged.
Microtags (pips) are often created by laser software and are usually unavoidable. These small tags, typically measuring 0.3mm to 0.5mm, remain on components to prevent tipping during the cutting process, which could lead to costly damage to the laser head. Small holes often allow components to tip and fall safely into the laser bed, while larger cutouts are typically stable enough to avoid the need for microtags. However, small components and medium-sized cutouts (around 150mm wide) may require tagging for stability.
As a result, a small pip (around 0.2mm) may remain on the inside of cutouts or the exterior of parts. If it’s crucial for your components to be pip-free, we can remove these tags, leaving a smooth finish. This service must be requested and will incur an additional cost.
Since removing microtags can be time-consuming for larger batch orders, our default practice is to leave the pips intact. This issue is not unique to MEC but is common among any company using a flying optic setup, which includes most lasers, plasma cutters, and waterjet machines.
