Introducing the micro threader RP020 28 March 2019

A member of the SACMA Group, Ingramatic has introduced the smallest threader inspired by its I-Thread concept, the micro threader model RP020, W00/W000 die sizes, for the high-speed production of very precise miniature screws.

Ingramatic’s well known modular ‘I-Thread’ machine line provides many innovative features such as the motorisation of the die match; a single starter unit driven by torque motor motion; and the patented double starter unit driven by servomotors. These two types of starter units have, as a standard function, the self-learning adjustment of the starter fingers to make the set-up of the blank introduction easy and quick. Ingramatic states it is the first worldwide company to have engineered a solution for the whole range of machines from M1 to M33.

The new machine is equipped with the latest technologies available as an innovative tool holder, such as an introduction system driven by a torque motor for an ultra-precise introduction of the miniature blanks into the dies. The most innovative feature is the slide body running on linear guides (with ball circulation skates) in order to ensure a very high accuracy for the rolling operation – allowing the production of parts with an extreme precision and reliability. The drive transmission of the RP020 is made by an innovative double helical drive belt connecting the brushless main motor with an absolute master encoder. This new type of drive with double helical belt favours higher torque and precision.

The RP020 is also equipped with the same advanced functions of the ‘I-Thread’ machines, such as the self-learning adjustments of the starter unit. Plus, the introducer stroke can be adjusted by the operator panel or by means of the electronic handwheel, so technicians don’t need to make any manual adjustment with service wrenches – ensuring speed and accuracy of measure change. To guaranty durability and precision, the frame is made of spheroidal cast iron and the SC-Matic interface ensures the management of the motorised adjustments.

In addition, to give a better understanding about the undisputable capacity of Ingramatic to design modular machines with the highest level of sophistication, to serve the most exigent users, the machine can be installed in less than one hour thanks to its plug and play capacity.
