Typically, HSK chucks are supplied with a hole through the interior of the cone. The hole is designed to accommodate a data chip (Balluff Chip) for tool tracking, and can also help aid in the release of the chuck from the motor housing if it comes stuck. For some customers who are having concerns about contamination and/or dust entering into the spindle via this hole in the tool holder cone, here is a solution! GDP Tooling offers an inexpensive “Center Plug” that can be quickly installed. Once inserted, the plug becomes integrated with the chuck and will not affect the integrity of the chuck, motor or tooling. This is an inexpensive, simple and easy solution! As a reminder, it is recommended to thoroughly clean your chucks, collet nuts and collets on a regular basis…remembering to install NEW collets (ER32, ER40, SYOZ25 & RDO35) every 500 machine hours!
Some machine manufacturers, in particular, SCM Machinery, routinely recommends the use of HSK tool holders that either have this enter hole plugged, or not there in the first place. Since the hole is part of the standard tool holder design specifications to accommodate the Balluff chip, finding such tool holders can be difficult. Here at GDP Tooling, we stock the HSK-F63 – ER32 collet style, specifically for SCM machines that are manufactured without the hole. Our Part # for this design is 6375.632.10
