Mobile cali­bra­tion test bench » Cali­bra­tion of hand-held nutrun­ners and built-in nutrunners

Mobile cali­bra­tion test bench

Our robust cali­bra­tion test bench offers the perfect solu­tion for the precise test­ing and cali­bra­tion of nutrun­ners with a torque up to 500 Nm.

This test bench offers maxi­mum versa­ti­lity with speci­ally adapted moun­ting plates for each size and thumb nuts for secure fastening.

Tool clamps ensure addi­tio­nal fixa­tion of the nutrun­ner. The tigh­tening simu­la­tor is atta­ched to the base plate.

The height can be easily adjus­ted with the hand­wheel, depen­ding on the confi­gu­ra­tion of the simu­la­tor and the instal­la­tion size of the refe­rence measu­ring sensor.

QS box digi­tal measu­ring system

The QS box digi­tal measu­ring system from DSM offers an effec­tive solu­tion for the cali­bra­tion of nutrunners.

The combi­na­tion of QS box, a suita­ble torque sensor and the MQS soft­ware ensu­res a compre­hen­sive measu­re­ment procedure.

Each measu­re­ment is carried out on the basis of the infor­ma­tion ente­red about the measu­ring equip­ment, the nutrun­ner to be tested and the defi­ned measu­re­ment para­me­ters. The soft­ware not only conducts measu­re­ments but also serves for display­ing the measu­red values and conduc­ting analy­ses.

This analy­sis func­tion enables a thorough evalua­tion of the measu­re­ment results in order to iden­tify any devia­ti­ons or trends and take appro­priate action.

Frequently Asked Ques­ti­ons (FAQ)

1. What is a mobile cali­bra­tion test bench?

A mobile cali­bra­tion test bench is a porta­ble system desi­gned to cali­brate hand-held and built-in nutrun­ners directly on-site, elimi­na­ting the need to send tools to exter­nal laboratories.

2. What are the advan­ta­ges of using a mobile cali­bra­tion test bench?

It redu­ces down­time, saves trans­por­ta­tion costs, and allows for cali­bra­tion under actual working condi­ti­ons, ensu­ring grea­ter accu­racy and efficiency.

3. Which types of nutrun­ners can be cali­bra­ted with this bench?

The bench is suita­ble for cali­bra­ting various models of hand-held and built-in nutrun­ners, inclu­ding those from the DSM DSH and DS series, with torque ranges up to 500 Nm.

4. How does the cali­bra­tion process work?

The nutrun­ner is moun­ted on the test bench and connec­ted to a torque sensor; the system then measu­res and compa­res the output against prede­fi­ned stan­dards to ensure accuracy.

5. Is the mobile cali­bra­tion test bench compa­ti­ble with third-party tools?

Yes, its modu­lar design and adap­ta­ble moun­ting plates allow for the cali­bra­tion of nutrun­ners from various manu­fac­tu­r­ers, not just DSM products.

6. Can the test bench be inte­gra­ted into exis­ting produc­tion lines?

Abso­lut­ely; its compact and flexi­ble design enables seam­less inte­gra­tion into current work­flows without signi­fi­cant modifications.

7. What docu­men­ta­tion is provi­ded after calibration?

A detailed cali­bra­tion report is gene­ra­ted, docu­men­ting all measu­re­ments and ensu­ring tracea­bi­lity in compli­ance with quality manage­ment standards.

8. How often should nutrun­ners be calibrated?

Cali­bra­tion frequency depends on usage inten­sity and quality requi­re­ments, but a regu­lar schedule—such as annu­ally or after a set number of cycles—is recom­men­ded to main­tain precision.
