Service hotline – your direct line to our service team The fastest and most cost-effective solution to your service needs is a telephone call between our expert service personnel and a customer staff member responsible for the system, ideally someone who has had training from DEPRAG. If a solution cannot be reached over the phone, our service centre will immediately initiate further steps to address the issue. Depending on the agreements made, our service team can also be on site at your premises within a short space of time. The first port of call is the service department at DEPRAG. Our...

Screwdriving technology services Screw joint analysis Processing reliability right from the start - due to a comprehensive screw joint analysis during which our experts put your specific screw joint to the test. Your advantages: ■■ Identification of optimal processing parameters ■■ Processing reliability right from the start ■■ Analysis of seating conditions ■■ Recommendations of suitable screwdriving procedures Frequently asked questions: ■■ Which is the ideal torque for my application? ■■ What speed should I choose? ■■ What tool best fulfils my requirements? Torque measurement and screw...

Screwdriving technology services Screw joint analysis – Standard analysis: The screw joint analysis can identify a suitable screwdriving procedure and determine the optimal shut-off torque of the screwdriving tool. Parts for assembly are positioned in an almost identical replication of the assembly conditions. Next a screw is assembled with the screwdriver using a higher torque than reasonably expected so that the assembly is overloaded and fails. The torque, screwdriving time and angle are recorded and saved for this procedure. The torque curve progression can be used to analyse the...

Screwdriving technology services Machine capability study (MFU) – processing reliability in screwdriving technology  MFU certificate for screwdriver with clutch, torque  MFU certificate for EC / EC-servo screwdriver, angle or torque The extensive inspection conducted for an MFU uses traceable calibrated measurement reference equipment. An MFU for angle is also an option for electric tools. A machine capability study is the inspection of a machine for its suitability to a specific screw assembly task. In contrast to a machine capability study, the processing capability (Cpk) can only be...

Screwdriving technology services Torque adjustment – upon delivery of your screwdriver with mechanical shut-off clutch As standard our screwdrivers with mechanical shut-off clutch are set to maximum on delivery. On request we can set a specific torque for you on delivery in order to guarantee the continued reliable function of your tool. Your advantages: ■■ reliable processing ■■ comprehensive documentation ■■ traceable to national norms You also receive the corresponding measurement protocol. When taking a counter measurement using a measurement platform (measurement transducer) and...

Calibration service With a calibration from DEPRAG you can always be sure that your measurement equipment provides reliable measurement results – competent and with the requisite traceability to national norms. DEPRAG has an accredited calibration laboratory where various calibration methods can be employed to calibrate with traceability and the lowest measurement uncertainty, covering torques of between 0.01 Nm and 500 Nm. How long is the calibration valid? In principle a calibration is only valid at the time it is conducted. It is normally the responsibility of the user to decide on the...

Over the years if maintenance or modifications are required, our experienced service technicians are swiftly at your side. Specific reaction times can...

Air motors Torque regulation The characteristic curves are determined using torque regulation. From one torque M = 0 (corresponds with the idle speed of the tool being checked), the torque is then increased in stages to a max. of 500 Nm. Speed regulation The characteristic curves are determined using speed regulation. For each process a maximum speed, a minimum speed and a maximum torque, according to preference, are defined. A test protocol with the characteristic curve of the tool is produced and delivered with the tool as documentation. Some technical data as a guide: Tool speeds: Tool...
