Remove the fast-exchange plate
- Lower the Z axis all to the minimum.
- Remove the fast exchange attachment from the Z-Axis by loosening the 4 screws holding it.
The upper drive will be directly fixed to the Z stage without the fast exchange attachment.

- Position the load cell in contact with the Z Stage direct support.
- While holding it in place, fasten the 4 captive screws as shown below.
The 4-pin holder of the Fz load cell must face downwards.
The slot connector of the load cell must be pointing to the right.
Slide in the upper drive
- Slide the upper drive into the load cell pins.
Please pay attention to the notch, circled in orange, which must point towards the back.
After sliding it in, the upper rotary drive is now supported by the 4-pins.
- To secure the upper drive, tighten the 3 captives screws using a 5/32" Allen key.
There is only one captive screw on the right.
Connect the cables
Connect the load cell cable then lock it in position by pulling on the two-sided levers.
From the back of the MFT-5000, you’ll find the 2 slots located on the left, behind the frame.
The torque sensor connector is on the left of the upper drive.

Required Tools and Components
Assemble and attach the Upper Ball Holder
- Insert the Ball into the collet.
Ball specifications
Diameter: .500" / 12.700mm
Material: E52100 Alloy Steel
- Insert the collet into the upper holder.
- Using a 1/8” Allen key to push out both the collet and the ball
- Using a 3/32” Allen key to push out the ball from the collet
Make sure to match the collet ball’s notch with the dowel pin’s holder.
To dismount the upper holder
Insert a Allen key at the back to fully dismount the assembly.
Attach the upper ball holder
- Insert the ER-32 collet into the ring, then place it into the upper drive.
- Slide the ball holder into the UpperDrive’s collet.
- While holding the drive in place using the included 36 mm wrench, use the ER-32 wrench (provided in the kit) to tighten the collet securely.
Tightening using the two wrenches prevents applying direct torque on the upper drive.
Raise the Z-axis using the jogbox, once the drive is properly installed to facilitate next steps.
Mount the self-adjusting platform
Prepare the 4Ball Container
Follow the Dry or Grease Container montage below depending on the test.
Assembling the 4ball oil container
- Empty the container and pull out the thermocouple probe.
Cleaning procedure before test
- Immerse container components and balls in Stoddard solvent, swirl or ultrasonically clean for 5 minutes.
- Transfer to fresh Stoddard solvent, swirl or ultrasonically clean for 1 minute.
- Rinse in n-heptane, swirl or ultrasonically clean 1–2 minutes.
- Air-dry 10 minutes in fume hood or warm air stream.
- Assemble immediately into the test cup using clean tweezers.
- Insert the three balls into the empty container, without forgetting the positioning pin.
The thermocouple probe must be pushed close to the balls.
- Put the clamping rings. Make sure the clamping ring with the 3 notches faces towards the ball (opposite from the picture). Then the chuck insert above.
- Finally, put the nut.
For Oil Preparation
Pour the oil to be evaluated into the test-oil cup to a level around 3 mm above the top of the balls. Ensure that this oil level still exists after the test-oil fills all of the voids in the test-oil cup assembly.
Assembling the 4ball grease container
- Empty the container and pull out the thermocouple probe.
- Immerse balls in Stoddard solvent, ultrasonically clean for 5 min.
- Transfer to fresh Stoddard solvent, swirl for 1 min.
- Rinse in n-heptane, swirl or ultrasonically clean 1–2 min.
- Air-dry 10 min in fume hood or warm air stream.
- Assemble immediately into the test cup using clean tweezers.
Cleaning procedure before test
- Insert the grease container and the positioning pin.
Insert back the thermocouple probe.
This pin prevents the ball from slipping during testing.
- Put the circular insert ,then place the 3 testing balls.
Make sure that the thermocouple probe is pushed very close to the balls.
- Put the clamping ring in place, then insert the chuck.
Tighten the 4ball container to 50 ft-lbf (67.8 N.m)
The attachment table must be fixed on a table for this operation. Tapping Inserts for Softwood are provided with the table.
- Take the provided torque wrench and adjust it to 50 ft-lbs (67.8 N.m). Place the 6 Point Impact Socket 2-1/4” on the torque wrench.
- Place the 4ball container on the attachment table by respecting the correct orientation (different pin diameters).
- Tighten the 4ball container on the attachment table using the torque wrench.
The torque tightening is carried out according to ASTM standards, and has a direct impact on the friction outcome, including the welding process.
After use, the torque wrench should be stored at its minimal torque value (10 ft.lbf / 13.6N.m)
Install the 4ball container on the platform
- Align the two guide pins on the self-centering platform with the corresponding holes on the bottom of the sample holder.
The two keyed pins are of different diameters, ensuring correct orientation.
Tapping Torque
The upper rotary drive is used to simulate taping torque, cutting test. The drive is mounted on an independent high speed Z stage. The rotary drive comes with various torque rated motors and gear ratio that allows it to cover wide range of test conditions. The drive has integrated torque sensor that cannot be removed. The drive has spring loaded assembly to prevent tap breaking during the test. Optionally install quad band load sensor that measure the down force during the test. Multiple quad band load cells can be purchased to change force accuracy measurements
Consumables
- Standard - taps up to 1/4 inch
- Standard Lower Bar with 140 holes at 6mm distance. Bar dimension 125x47x18mm . M4 20mm (forming) or M4 12mm (cutting)
- Shank diameter 5/8. Minimum Tap #0, Maximum tap capacity 1/4, M7
- Standard Drills M6 0.5mmPitch, 1 inch thread length, 2.5 0,all Lg, 5.5mm
