Manufacturing Technology

Through a combination of decades of know-how, and its significant R&D potential, SASPI is able to constantly reengineer and update its thread rolling machines to meet the actual and future requirements of customers – without losing the well known reliability and robustness. 

The new generation of SASPI thread rolling machines feature a number of innovations that stem from its know-how and R&D capabilities, including a new cast iron body design – with SASPI stating that the cast iron shock absorption and heat expansion properties are unbeatable by other technologies. 

Other features include servo driven camless machines; more user-friendly set-ups – with motorised rails and feeding systems, including carbide inserts for longer life and easier replacement; better ergonomics and fulfilment of the latest CE safety standards; state of the art technology implementation for patented die pressure adjustment; electronic handwheel jogging and touchscreen controlled die match – adaptable to the latest process monitoring technologies; a 15 degree single pusher system that ensures a longer die life and better thread quality; as well as wireless remote accessibility and Industry 4.0 connection (with MQTT and OPC-UA protocols), with a built in OEE performance control.

SASPI’s machines can also be equipped with an induction heating unit in which the pieces are heated to a certain temperature. “The machine can ensure the parts are heated to a desired temperature range so the material does not lose properties and only suitable parts are threaded,” explains SASPI. “With over 60 years in the industry, our machines have developed a strong presence in the aerospace, automotive, construction and household sectors.”

Combined technology

In addition to its thread rolling technology, SASPI is able to supply a wide range of secondary operation machines that are highly appreciated for their speed and precision, as well as their high technology and versatility. These machines’ main characteristics are their ability to do various operations at the same time – shaving, drilling and broaching, as well as heading operations. 

A key machine within the SASPI secondary operations range is the MPA automatic pointing machine, which is well known for being a very reliable and easy to use high-speed pointer. It is fully motorised (centring, rails, top rail, cutting depth, etc) and is a very versatile machine that can run parts from M2 (0.078 inches) to M14 (0.55 inches) in lengths from 4mm (0.19 inches) to 150mm (5.9 inches). 

“One of the greatest features of the MPA is that every part is held as close to the end as possible during the machining process – regardless of the length,” mentions SASPI. “This means vibrations at maximum are avoided and we gain precision and finishing quality of the part, as well as tool life. This is a unique feature of SASPI machines.”

The MPA machines can be used for pointing and facing, drilling, and broaching, all types of materials, from different steel alloys and parts after heat treatment to materials used in the aerospace industry, such as titanium and inconel. The MPA machine is a 3 in 1 machine with a quick and easy changeover. Its high-speed and robustness is also appreciated in the automotive industry and its high precision and delicacy with parts is highly recognised in the aerospace industry.

The latest version of the MPA is the MPA-14CL, with its main characteristic being the lack of cams. “Every single movement of the machine will be easily adjustable and configurable to customers’ needs. It will start as a pointing, drilling or broaching machine but its potential is beyond these processes,” reports SASPI. “This user-friendly machine introduces a brand new technology with all the experience and features of the well known SASPI MPA secondary operations machine.”

Another new machine available from SASPI is the new version of the DOM-16, a very reliable and easy to use secondary double operations machine that can be used for pointing and facing, as well as drilling and broaching of all type of materials, from different steel alloys to materials used in the aerospace industry such as titanium and inconel. It is equipped with one machining station for the pointing and drilling operations and a heavy-duty broaching station to broach different profiles. This type of machine is mainly made for the aerospace industry and is highly appreciated for its speed and precision, as well as its high technology and versatility.
