1.4.6 Disassembly, Cleaning, and Lubrication of Miniature Stroke

Bearing

Since the disassembly, cleaning, and lubrication work of the minia-

ture stroke bearings requires highly sophisticated technique, consult

our service personnel for details.

••

• Time for Inspection, Cleaning, and Lubrication

Perform inspections every month.

Cleaning and lubrication are required when dirt and dust have accu-

mulated on the sliding part of the shaft and the movement is ham-

pered or on the hollow portion of the shaft and the suction force has

deteriorated.

Be sure to clean the miniature stroke bearing every 6 months.

• Disassembly of Miniature Stroke Bearing

Disassembly Procedure

(1) Set all nozzles to "L Level".

Refer to "4.2.2 "Manual Opn" Tab" in "Section

6 (Volume 2: Operation (Supervisor)" for the

detailed information on how to change the

nozzle level.

(2) Make the X/Y table retreat.

Refer to "4.2.1 "Noz Cleaning" Tab" in "Sec-

tion 6 (Volume 2: Operation (Supervisor)" for

the detailed information on how to make the

X/Y table retreat.

(3) Turn off the power and air sources of the ma-

chine to discharge the air from the machine.

(4) Detachment of Head Assembly

(4-1) Loosen 2 M4L12 bolts (upper ones) and 2

M4L16 bolts (lower ones) fastening the head

(5) Loosen 3 setscrews fastening the diffusion

plate with the 2 mm bit (Standard Accessory

Part: 630 116 3673) and detach the diffu-

sion plate from the head.

Do not apply a wrench, etc., to the mag-

net for head origin detection.

Otherwise, the magnet will be

Notice

(7) While pressing the holder, loosen 2 setscrews

on the upper area of the head adequately with

the 1.5 mm bit (Standard Accessory Part: 630

116 3673) to detach the holder from the head.

(a) Carefully loosen 2 setscrews be-

cause the holder pops out upward.

(b) To avoid damaging the tapped hole,

use a hexagon wrench (TONE,

BONDUS) that fits the diagonal di-

mensions.

(8) Detach the miniature stroke bearing (MSB).

(8-1) Detach the MSB shaft and outer cylinder.

Pull out the MSB shaft from the upper side.

Use a pair of tweezers to pull out the MSB

outer cylinder from the lower side.

Do not change the combination of the

MSB shaft and the MSB outer cylinder.

Otherwise, the smooth movement of the

head cannot be expected and the head

may have some leeway.

(9) Detach the upper seal, the collar, and the

lower seal from the MSB outer cylinder.

When the upper and lower seals are

scratched or deformed or foreign

substances have accumulated on

them, replace them with new ones

(630 048 0849).
