Aloris CXA19 Adjustable Knurling Tool Post Holder Cxa

Product Description

The ALORIS CXA19 is an adjustable knurling holder designed for use with CXA-series quick-change tool post systems on engine lathes. It accepts standard knurling tools and provides repeatable centerline positioning at 2 inches, allowing the operator to dial in the knurl without re-indicating between passes. The holder is built for lathes with a swing range of 13 to 18 inches, making it a direct fit for mid-size engine lathes common in job shops and maintenance environments. At 6.75 pounds, the casting is robust enough to handle the radial forces that knurling operations generate. Licensed machinists and toolroom technicians are the primary installers.

This holder is intended for mid-size manual engine lathes in the 13-to-18-inch swing class. Typical applications include form knurling on shafts, pins, and handles in both production and repair settings. The adjustable design allows the operator to set knurl depth incrementally, which is useful when working with softer materials that require a lighter initial pass before full depth is reached. It fits directly into a CXA quick-change tool post without additional adapters.

Key Features

• Adjustable knurling depth setting for controlled, repeatable passes

Compatibility

Designed for use with ALORIS CXA-series quick-change tool post systems on engine lathes with a swing of 13 to 18 inches.

Installation Notes

Installation is performed by a machinist or toolroom technician. Before mounting the holder, ensure the lathe spindle is stopped, locked, and the machine is powered down. Seat the holder fully into the CXA quick-change post and tighten the post locking cam to the manufacturer's standard engagement before applying any cutting load. Confirm centerline height alignment against the workpiece center before beginning the knurling pass.
