Mass precision laser drilling of parts
Automated machining for series production
What are the challenges in micro drilling parts for series production?
Precise laser drilling of small parts becomes praticulary challenging when large quantities must be machined. In many manufacturing processes, parts are handled in bulk, which further complicates handling and positioning. Mechanical processes quickly reach their limits with very small drilling diameters. Tool wear, burr formation or unstable processes are potentially severe issues. The challenges in micro drilling of series parts include:
- Very small drill diameters (3-500 µm): high process stability and precision requirements
- High tool wear in mechanical drilling causes downtime and rising costs
- Burr formation or damaged edges lead to scrap
- Complex handling and positioning of workpieces
- Difficult automation for very small parts
- Varying drilling quality at high production numbers
- Quality assurance in the production process
- Realization of product variants: variation of drill diameters and placements complicate processes and can require retooling of the machine
- Unsorted parts at high production volumes
Our solution: Automated laser precision drilling of small parts in series
Laser based manufacturing enables a new kind of process safety: micro drilling can also be automated in “unsorted parts”, enabling reproducible and economical manufacturing.
- Nonwearing tooling, contactless and burr-free
- Laser processes with extremely high resolution
- Automated feeding of workpieces for a continuous series production
- Singulation & precise positioning of small parts
- Handling solutions adapted to specific parts
- Highly reproducible laser processes
- Up to 100% parts inspection in the production process
- Stable process quality
- Easy integration with automated manufacturing lines
- Digital process chain, easy adaptation

Singulation & Automated laser machining in series
Pulsar Photonics has developed the P1000 automatic for automated machining of small parts. The machine is specially designed to machine small parts fed in as bulk material and to economically create micro-drillings in large quantities. The combination of automated feeding, precise positioning and stable laser machining creates a continuous process from singulation to the finished borehole.
- Machine availability around the clock
- Up to 100% parts certification
- Application-specific software solution
- Continuous monitoring of machining parameters
- automated feeding and singulation of bulk parts and bin-picking
