7.5.1.1 Preparatory tasks
► Move the wafer table to the change position.
► Move the die ejector upwards.

► Twist the needle unit (1) off the lock.
► Pull the black cap (2) off. The needles (3) are located under the cap.
ð The needles are clamped in four sectors. One needle is in the center.
► The grub screws (4) at the four segments clamp the needles into place in the needle unit.
The center needle is held in placed by the bottom grub screw (5).

Ejection system, 5 needles with 2 mm spacing [00386908-xx]
► The 2x2mm needle kit requires a central needle fixture with a threaded pin 2x2mm, tightened
with a torque of 10Ncm.
► Depending on the application, fit the relevant needles into the openings in the four segments.

7.5.1.2 Setting the needles with the calibration standard [03098221-xx] (for die ejector,
magnetic)
Tools
●
Needles (wear part)
●
Calibration standard for die ejector, magnetic [03098221-xx]
The needles are all set at a defined height and common level with the help of the calibration
standard for the die ejector.

Procedure
► Remove the black cap on the needle unit.
► Carefully insert all needles into the segments and align the needles roughly in one line.
► Loosely tighten the grub screws. You must still be able to move the needles.

► Place the needle unit into the calibration standard for the die ejector (1).
► Place the ejection part into the device. The central bolt of this device must be against the ejec-
tion plunger and the bronze part must be flexibly against the radius nib.
► Turn the ejection part (bronze) into the required position.
► Press the bronze part slightly down into the prisms of the device.
► Push the ejection needles into the required holes (the threaded pin must be released).
► Move the spring-back adjusting slide in the direction of the stop bolt and hold it in place.
► Push the ejection needles in the direction of the setting surface (use tweezers) and pull the
ejection needle tightly into place with the threaded pins (torque 0.1Nm).
