with a high quality grease. Tyco Electronics
recommends the use of MolykoteH grease, which is a
commercially available lubricant. Lubricate according
to the following schedule:
Holder used in daily production—lubricate daily
Holder used daily (occasional)—lubricate weekly
Holder used weekly—lubricate monthly
Wipe excess grease from tool holder, particularly from
die closure areas. Grease transferred from the die
closure area onto certain terminations may affect the
electrical characteristics of an application.
5.2. Periodic Inspection
Regular inspections of the tool holder should be
performed by quality control personnel. A record of
scheduled inspections should remain with the tool
holder or be supplied to supervisory personnel
responsible for the tool holder. Inspection frequency
should be based upon amount of use, working
conditions, operator training and skill, and established
company standards.
1. Inspect the tool holder for missing pins or parts.
If parts are missing or defective, replace them by
referring to Figure 4.
2. Check all bearing surfaces for wear. Replace
any worn parts.
