Production process
of surgical scissors
As part of the process chain for manufacturing surgical scissors, the Berger Gruppe offers solutions for a large part of the production steps. Here too, automation solutions and grinding processes are at the heart of the product range.
Integration of production processes
Various production processes can be integrated into a robot cell, such as build-up welding, bending presses, drilling/countersinking …
A CNC milling station with a special device was integrated into the production system for centering, drilling, tapping and milling the carbide recess of surgical instruments.
- Machining center for drilling and milling work
- Bending press to achieve the bending up
- Grinding machine BG1/ZA for processing the stalk/inside
Automation of laser deposition welding
Automated cell for laser cladding in conjunction with a six-axis robot for guiding the laser source and/or for loading and unloading the device.
Grinding processes for surgical scissors
The BG0/RV series flat bevel grinding machine is designed for grinding highly curved radii on surgical scissors, tweezers, forceps or similar workpieces. The BG0/RV uses four axes to grind highly curved radii. The contour is measured by laser and the recorded data is exported to the program interface.
Different machining operations are possible in separate clamping:
1. half moon
2. hollow side
3. outer leaf
4. (a-c) facet cut outer blade
Bevel grinding on mounted scissors
The robot grinding stations of the RSP series can be configured to achieve bevel grinding on mounted coated scissors.
Different processing stations are used depending on the requirements and workpiece properties. Automated cell for laser cladding in conjunction with a six-axis robot for guiding the laser source and/or loading and unloading the device.
The robot cell of the RSP4B/1K/1M series shown here is equipped with:
- Four belt grinding stations from the BSS10 series
- a vertical rotary table magazine
- a camera measuring station with two cameras
Polishing surgical scissors
The CNC-controlled PS double shaft polishing machine is designed for polishing bone nails, bone plates, scissors and similarly shaped workpieces. The machine is equipped with a control system in which all process parameters are programmed in a user-friendly manner and saved depending on the workpiece.
Thanks to the short changeover time of just a few minutes, the machine can also produce small batches economically. PLC control for setting the machine (paths, distance, speed, etc.)
- Infinitely variable speed-controlled polishing roller drives
- Polishing paste shot control
