*USED* Knee Control Assembly;K109

Keep your knee-type milling machine humming with this used Knee Control Assembly, part number K109. Crafted for reliable performance and budget-friendly refurbishment, it’s an economical way to restore precise knee movement and maintain productive workflow in metalworking shops.

What it does

The knee control assembly governs the vertical travel of the mill’s knee, enabling accurate table height adjustments for every cut. With a solid control interface, you can dial in cutting depths quickly and repeatably, helping you achieve consistent results across multiple parts and setups.

Condition and value

Condition: Used. This item shows typical wear from prior installation and operation. It is sold as-is, without additional components beyond what’s listed in the description. Review compatibility with your machine’s model and mounting pattern before purchase to ensure a proper fit.

Key benefits

• Direct-fit potential replacement for knee control assemblies used on traditional knee-type milling machines
• Supports smooth, repeatable knee movement to improve setup speed and cutting accuracy
• Cost-effective option that reduces downtime when refurbishing older equipment
• Suitable for restoration projects, shop upgrades, or field service where a quick repair is needed
• Works with standard mounting interfaces common to many knee mills (verify fit for your specific machine)

Use cases and ideal buyers

Perfect for machine shops, maintenance technicians, and hobbyists restoring legacy milling machines. If you’re refurbishing an older knee-type mill or temporarily replacing a worn knee control to keep production moving, this K109 assembly offers a practical balance of affordability and functionality.

Installation and care tips

Before installing, compare the mounting pattern and actuator interfaces with your machine’s manual. If the K109 matches your knee control layout, swap-in can be straightforward, typically requiring standard fasteners and connectors from your existing hardware. After installation, operate through the full range of motion to check for smoothness and absence of binding, and follow your machine’s maintenance schedule for lubrication and inspection of pivot points.

Bottom line: this used Knee Control Assembly K109 is a cost-conscious pathway to restoring knee motion and maintaining production in aging machines. If it aligns with your model, it’s a sensible choice to extend the life of your milling setup.
