I understand there is a toolholder dropping issue for RM500B, TAS00114.
Can I have more information on this?
#no. of toolholder dropped? (There is 1 toolholder dropped last week)
#Any broken toolholder?
#Have the dropped toolholder been replaced?
#Has the Parts dept ordered more toolholders (p/n:151-9941) to keep stocked?
Procedures for loose bolts
1. Hit tool holder (1) on the front of T section (4) four to five times with a steel hammer that weighs 1.8 kg (4 lb) to 2.25 kg (5 lb). This will drive tool holder (1) into base (2). At this point, tool holder (1) and base (2) will be locked together by the tapers.
2. Striking the tool holder with the hammer will cause a dull heavy sound. When the tool holder has been seated in the base, striking the tool holder with the hammer will cause the tone to change to a high pitch. The change of tone signifies that the tool holder and the base have locked together.
3. Once tool holder (1) has seated in base (2) install bolt (3). Tighten bolt (3) to a torque of 88 ± 7 N•m (65 ± 5 lb ft).
Note: Do not use only the torque on the bolt to seat the tool holder. The strength of the bolt is insufficient to apply the required load for assembly.
4 Operate the machine for four to six hours.
5. Check the tool holders and bolts. Reseat any loose tool holders and tighten any loose bolts. Refer to Step 1.
6. Operate the machine for 10 to 12 hours. All tool holders should be tight. If any tool holders are loose disassemble the tool holders. Reassemble the tool holders. Refer to Step 1.
7. Tool holders and bases that have been tightened twice are locked together by the tapers. The tool holders and bases should remain locked under normal working conditions. Loss of bolts from a properly assembled unit is not detrimental. The tool holder and the base are locked together by the tapers.
The following are communicated to the customer on the 2nd Sept
#Told Murugan (Kok Kiat Site Supervisor) to get a bigger hammer to hit on the toolholder into the base.
# Tighten bolt to a torque of 88 ± 7 N•m (65 ± 5 lb ft).
# I will follow up with Murugan on the status this week on the outcome.
