Hi ,I am totally confused at the vast array out there and would really appreciate some guidance on what machine to go for, i am looking to remove restrictors from inside inkjet cartridges ideally say 50 units at a time , so mainly plastic work and occasionally, aluminium , the depth inside the cart is apx 30mm , would also like to do some engraving , so probably a router type machine ,.
Have been looking at the Heiz z S400 and the T400 but dont know if this is overkill for my requirements

Any guidance greatly appreciated

Mike.
