7.4 SOFT STOP SCREWDRIVER ( GXS Driver )
Soft Stop screwdriver has special designed clutch with the bearing of one way
direction rotating. This driver can control the torque for clockwise fastening.
It will have the stall torque in counterclockwise (Reverse) rotation.
Don't loosen the screw over 12 Kgf.cm of tightening torque
Be careful to loosen the screw which was fastened with the other tool.
1) Main features of GXS
- High torque repeatability
- Low G-shock Less than 5G ( Bronze spring ), 10G ( Silver spring )
- ESD Free option available ( 0 ohm by Chrome plate, Less than 10k ohm by conductive case )
- Accessories available ( Vacuum screw pick-up )
- Available with automation system
2) Low G-shock
G-shock test GX80 29G in Hard joint
G-shock test GXS80 5G in Hard joint
DOGA BRUSHLESS ELECTRIC SCREWDRIVERS / GX SERIE 14
- G-shock is very different according to the joint characteristic, set torque and rotating speed.
- Hard joint, higher torque and speed makes much G-shock than Soft joint, lower torque and speed
- GXS screwdriver shows approx. 2.5 G to 10 G in different condition.
- G-shock Test report ( Hard joint M4 screw fastening )
