Motivation for automation

The customer specializes in machining high-precision parts in stainless steel, steel and aluminum. Due to the customer's focus on the automotive and aerospace sectors, particular emphasis is placed on the quality of the goods supplied. Due to the enormous production volume and the shortage of workers on the market, full automation of the process was introduced. With a strong vision to expand the product range and the need to respond to turbulent changes in the future, the customer opted for automation in the form of an HXG platform, which will enable them to respond to change better than a single-purpose machine.

Project description.

The subject of the implementation was the development and supply of equipment for deburring and stretching of transition holes and exit control. The main parameter to be controlled is the diameter of the hole, the diameters of the notches on the shank.

In view of the customer's need for rapid response to changes, the equipment was designed on the HXG platform - a reconfigurable robotic platform in configuration:

HXG Core - Fanuc (centre) with dedicated gripper
Module 1 - Input pallet tray
Module 2 - Input pallet tray
Module 3 - Inner diameter optical inspection station
Module 4 - Module with XYZ compensated spindles
Module 5 - Grinding module
Module 6 - OK/NOK Output Box

Process Description:

Parts are oriented and loaded into pallet trays compatible with the HXG pallet module
The robot takes 2 pieces of parts at a time into the gripper
The robot guides the parts onto the compensated spindles with tools
Robot feeds parts into station for non-contact length and diameter measurement (+-0.005mm)
The inspected parts are sorted into the OK box and then, depending on the type of defect, into the NOK box.
The device collects data and communicates with the parent ERP system
