The company Erre Enne owns 5 CNC-controlled horizontal boring machines which are equipped with a sleeve for the milling and boring of holes with a diameter up to 800 mm and is specialized in the realization of prototypes and small series. The diameter of the sleeve varies in function of the machine, for example with a sleeve diameter of 100 mm we can bore up to 450 mm with our Bragonzi machine, with a sleeve diameter of 110 mm we can bore up to 500 mm with our Castel Green and San Rocco and with a sleeve diameter of 130 mm we bore up to 750 mm with our Pama machine.

All of our boring machines are equipped with an ISO 50 mandrel, automatic tool changing units and rotary tables which are continuously controlled in 360.000 positions.

The company is also specialized when it comes to boring with the help of precision boring tools, which guarantee the highest precision. We are able to work up to 2.800 mm x 2.000 mm with a maximum load of 3.000 kg.

All our machines are connected by an internal network, where processing programs are managed and saved and with the help of Cam-programs (Mastercam) our technical department is able to anticipate and help with problems with extraordinarily difficult forms or where a 3D programming is necessary, so that the processing of the piece is not interrupted and the operator can go on without problems.

Every single department of our company is able to work autonomously, that means from the beginning of the working process (in the technical department) to the realization of the workpiece.

More precisely:

• Correct interpretation of technical drawings
• Clamping of workpieces
• Realization of the work program directly at the machine tool
• Preparation of the necessary tools
• Control of every single step and the whole work cycle
