The all-in-one screw making machines cover all manufacturing steps from cutting the input stock down to the sorting of the finished products. They are designed to produce screws or bolts in length from 80 to 2,000 millimeters or more. The maximum length depends the rod’s resistance to sagging.

AMBA is the only manufacturer in the world to design machines that produce this size of screws.

Being of modular design, the machines offer a great deal of flexibility. AMBA customizes its machines to individual specifications.

The multitalent

A single machine, consisting of harmonized components, can perform the following operations fully automatically:

• Cutting of up to a 12 mm diameter rod
• Pre-form and finish upsetting – also with spring-mounted tools
• Punching of hexagons in two steps including burr removal
• Reducing of diameters over lengths up to 100 mm and more
• Pinching with pressing forces of up to 40 t
• Thread rolling with rolling jaws down to TR 6 and up to 160 mm wide as standard 
• Milling as an inline process
• Sorting the finished products into transport boxes
• Mechanical Processing of Wire-Ends
• Welding of Bi-Metal
• Local inductive heating up to 1000 °C/1800 °F

Technische Prinzipien

• Infinitely adjustable drives, controlled by frequency converters
• Full power output also in the low rpm range
• Programmable logic converter (PLC)
• Separate central lubrication systems for different machine sections
• Centralized cooling lubricant supply
• Horizontal transport of the components with spindle-technology
