Control technology boosts screwdriving performance
An innovative control system gives line engineers complete control of all automated screwdriving parameters, with the ability to produce an almost infinite variety of programs.
Manual screwdriver has automatic feeding
A new low cost manual hand screwdriver with automatic feeding offers an accessible method of achieving increased production levels in a wide range of industrial applications.
To ensure that a multitude of fastening tasks can be accomplished using the same tooling, Weber has designed an automatic feed system on its SA series screwdrivers that can be used with screws, nuts, studs or many other types of fastener.
Spindle modularity on the SA series has helped to maximise tool flexibility.
The spindle combines a functional, user-friendly design within a compact envelope, ensuring that maintenance downtime, toolchanges and cycle times are kept to an absolute minimum.

Flow drill screws replace BIW rivets and welding
Using flow drill screws rather than rivets or welding in BIW vehicle assembly, enables tough joints to be achieved faster and more efficiently, without affecting the strength or long term integrity.
Screwdriving unit integrates process control
A screwdriving control unit allows the operator to input freely configurable process parameters to achieve integrated programmable cycle control.
One of the methods helping to achieve this is by parallel mounting both the head and bit stroke modules, so reducing the overall length of the driver assembly.
To keep maintenance routines as simple as possible, no special tools are required to release the driver head, driver bit or perform other routine maintenance tasks.
Other benefits of the SA series include special castellated component connections that ensure perfect alignment of modules, and a choice of drive motors.
Pneumatic, AC electric or DC servo drives, allow users to select the drive of choice without having to make special factory requirements.
The SA series is also suitable for right or left hand fastening applications.
There are four models in the SA series, with torques ranging from 0.1-3Nm on the smallest SA 03 model, up to 10-100Nm on the SA 100.
When special requirements are made on quality, reliability, process control and documentation, SA series models can be incorporated into Weber electronically controlled screwdriving systems.
Modular programming by means of staged screwdriving is an innovative concept developed by Weber whereby each screwdriving program consists of several sequential steps.
For each step, users can define the task to be completed and the parameter values to be deployed.
Such is the versatility of the concept that the screwdriving process can be selected from a number of standard operations, such as run-up steps, screw-in steps, seat-in processes, as well as tightening and loosening procedures.
There are also special processes for Not-OK handling, data transfer, jump commands and PLC commands.
A variety of torques, rotation angles, screw-in depths, operating times, revolutions and motor current values are defined as the initial, threshold, cut-off or monitoring values of the parameters.
