CLAMPING FORCE MEASURINGINSTRUMENT HSK + SKAccurate measuring of the clamping force for HSK/SK clamping systemsThe accuracy of the HSK connection does not only dependon the geometry but also on the drawing force of the HSKclamping system which plays an important part in ensuringa powerful and dimensionally accurate connection.Toensure operational safety, a regular clamping force checkof the HSK interface is recommended.An entirely mechanical clamping force measuring instrumentis now available from Guhring. Its operation is basedon components, which are linear adjustable in length andpositioned proportional to the force. A force is associatedwith the alteration in length which is displayed via an analoguedial gauge.Specifications:• few components, therefore cost-efficient• robust design• battery or mains connection not required• patented operating principle which is also adaptable toother spindle designsWe deliver the clamping force measuring instrumentGuhring no. 4974 in a wooden case, calibrated, withinspection protocol and measuring instructions.Minimum required pull forces for clamping systemstaper size HSK325 kNtaper size HSK406,8 kNtaper size HSK5011 kNtaper size HSK6318 kNtaper size HSK8028 kNtaper size HSK10045 kNtaper size SK306 kNtaper size SK4012 kNtaper size SK5025 kNDial gaugeDrawbarHSK-proofing bard 2d 1l 1forHSK-A/Cd 1SK d 2mml 1mmGuhring no. 4973 Guhring no. 4974Code no.

SENSO 3000Accurate measuring of the clamping forcefor hydraulic chucksThe hydraulic clamping technology is a well-known, provenand reliable method for the clamping of tools. Thanksto its completely closed design the system is sealed andimpervious, requires extremely low maintenance andguarantees longevity. Following many years of generaluse, however, thermal and mechanical influences can leadto a reduction in clamping force. The result can be a poortool life and a diminished surface quality including expensivetool breakages during machining operations.Determining the loss of clamping force was until nowextremely costly and inaccurate. It involved either determiningthe number of clamping screw rotations or thetorque with the assistance of a proofing bar and a torquekey or the expansion rate applying an accurate internalmeasuring instrument.SENSO 3000 determines the clamping force of the hydraulicchuck via a pressure sensitive plug gauge. The entirelength of the plug gauge is clamped in the hydraulic chuckso that when tightening the clamping screw the clampingpressure of the chuck is optimally applied. The clampingforce measuring instrument displays the clamping force asan absolute measurement value on the one hand and as apercentage clamping force in relation to a reference valuethat can be set individually on the other. This way, SENSO3000 can be adapted to customer specific application conditionsand requirementsThe clamping force measuring instrument is supplied witha plug gauge for the respective clamping diameter as wellas a carbide proofing bar for calibration purposes and a CR2430 type battery – all in a sturdy and handy case.The new Guhring SENSO 3000 measuring instrumentoffers a precise, quick and simple as well as consistentmethod of measuring the clamping force. An added advantageis the mobility of the system, i.e. for measuring withinmachines and fixtures.Clamping diametermmCode no.Guhring no. 4038Availability6.0 6,000 •8.0 8,000 •10.0 10,000 •12.0 12,000 •14.0 14,000 •16.0 16,000 •18.0 18,000 •20.0 20,000 •25.0 25,000 •32.0 32,000 •4 Optimal Lubrication

MQL-Check 3000Accurate measuring of the coolant volume and thereaction time with minimal quantity lubrication MQLThe development of Guhring‘s new MQL-Check 3000 allowssimple and quick measuring of the coolant volumeand the reaction time with minimal quantity lubrication(MQL) directly at the tool point. For the user, the resultis a considerable increase in process reliability with MQLmachining.Especially with minimal quantity lubrication, an optimaldelivery of the minimal coolant volume to the cuttingedge is paramount. An insufficient delivery or a delayedresponse time respectively can lead to fatal results suchas premature wear, a deterioration in machining qualityor even tool breakage. In contrast, an excessive coolantvolume results in increased costs through unnecessarycoolant consumption and additional cleaning expensefor components or machines as well as an unneccessaryimpact on the environment and personnel.Until now, measuring the coolant volume exiting at thetool point was practically impossible. With the MQL-Check 3000, Guhring is for the first time offering a simpleto operate measuring instrument for quickly checking thecoolant volume directly at the tool point. MQL-Check 3000is simply installed in the machine, the tool point is passedinto the measuring opening of the measuring unit andthe coolant delivery switched on. The measuring unit ofthe MQL-Check 3000 sends the recorded data wireless tothe associated display equipment, on which the resultingvalues are displayed in ml/h. Furthermore, the datainterface on the display facility allows the transfer of thedata to a PC as an option, making further evaluationsand above all the documentation of the measurementspossible.Subsequently, the user benefits from:• simple, quick measuring of the coolant volumedirectly at the tool point• ascertaining the actual response time, i.e. the timefrom starting the system to the coolant exiting atthe tool point• reproduceable and at any time comparablemeasuring data• a workshop suitable system, wireless operation -in terms of power supply as well as data transfer• comparitive measuring regarding function of MQLequipment, machine, spindle, tool holder and tool10 Optimal Lubrication
