Want pro results every run? We share OEM secrets. Keep reading for clean wins.

What Essential Tools and Setup Ensure Precision on Curved Surfaces?

Wrong tools blur lines. Curves twist designs bad. We at Sibottle pick right gear to fix that.

Fiber lasers (20-50W, 1064nm)1 pair with rotary attachments for 360° spins2 on 20oz bottles. Calibrate steps/mm at π times diameter to hit 90% accuracy on SUS304 curves.

Tools start strong at Sibottle. Fiber lasers lead for steel. They etch deep without spray. CO2 works coated ones. We test both in lines.

Setup fits curves key. Rotary attachments grip tight. Rollers suit straight. Calibrate Z-offset at 1mm. This keeps focus sharp.

Precision grows here. Jigs hold ten bottles batch. Speed hits 1,000 per hour.
