Hello,
you basically need two sets of two drilling spindle that you can adjust along one axis, manually or automatically by a simple MCU board you can program with a PC or your smartphone.
Then I would need to know if you plan to use this tool as an hand tool or you want put it in a working bench.
About me, over 20 years, my job consists in realizing working prototypes of products and systems, starting from an idea, and developing it with focusing on manufacturing aspects, and to the safety of workers and users, as well as well-looking design
i have a "solid" experience in both plastics and metal parts design and manufacturing via 3D printing, progressive die, casting, moulding, injection molding, as well as drafting of the necessary technical documentation (mechanical drawings, parts list, costs list)
Post design assistance is provided with no additional charges.
thank you for your consideration,
kind regards
Michele
