Description
Product Overview
The KKS UFB-3 is a specialised Universal Facing & Boring Head equipped with an MT3 (Morse Taper 3) shank.
Unlike a standard boring head that simply holds a tool at a fixed diameter, a Facing Head is a complex piece of engineering that allows the tool slide to feed radially while the spindle is rotating.
- Dual Function: capable of standard static boring (sizing holes) as well as Facing (machining flat surfaces), Grooving (cutting O-ring or snap ring grooves), and even tapering.
- Auto-Feed Mechanism: These heads typically feature a mechanism that, when the outer ring is held stationary (usually via a stop rod), drives the tool slide outwards or inwards automatically, allowing for precision surfacing at the bottom of a bore or on a boss.
- MT3 Shank: The integral Morse Taper 3 shank ensures maximum rigidity and minimizes runout compared to threaded-shank heads.
Condition
Used (Mechanically Sound / Cosmetic Patina).
This unit is in good mechanical condition.
- Function: The mechanics feel “tight” with no sloppy play in the slide, which is critical for accuracy.
- Taper: The Morse Taper is clean and free of any damage, it has been used with a 40 Taper adaptor its whole life, so no being put in and out of a spindle on the MT3 part.
- Cosmetics: It shows “patina” and some surface rust in areas consistent with age, but there are no signs of crashes, rubbing, or heavy abuse on the body.
- Inclusions: This listing is for the Head Only. It does not include boring bars, the case, or the stop rod (handle).
Brand Information
KKS (Kokusai Koki) is a Japanese manufacturer known for producing high-quality, rigid tooling. Their “UFB” series of facing heads are built to the same standards as the more famous Mizoguchi or Chandler heads, designed to last a lifetime in a production environment.
