Features of Lathe Wedge Type Tool Post
Lathe Tool Holder Post Title:
High Quality 250-222 tool post lathe wedge quick change tool post Black oxide Finish
The 250-222 Quick Change Tool Post Holder is known for its high rigidity wedge locking, fast tool changing, and repeatable positioning accuracy, making it suitable for stable and efficient machining of various processes such as outer circles, end faces, slotting, cutting, drilling/boring, etc. Used for fitting with the center rod/sleeve of the machine tool, actual accessories shall prevail.
Specification：
250-222 Wedge Lathe Quick Change Tool Post
Wedge-Type tool post (3"Lx3"Wx4-5/8"H)
Compatible model: 250-222 standard tool holder series
Swing (Inch):10-15inch
Structural characteristics and advantages:
Wedge locking mechanism: By pushing the tool holder with a wedge block, a strong and uniform clamping force is achieved. It has high rigidity and good vibration resistance, which is conducive to suppressing chatter and improving surface quality and tool life.
Quick replacement and high repetition positioning: With fewer tool changing steps and shorter time, it has excellent repetition positioning accuracy and is suitable for frequent switching and rhythmic production in multiple processes.
Materials and Heat Treatment: The tool holder body and key moving parts are usually made of alloy tool steel, which is quenched and tempered+precision ground, with high hardness, good wear resistance, and stable size and shape.

Installation adaptability:
Some sets come with or require the use of T-shaped nut plates, which require slight planing/machining according to the T-shaped groove of the machine tool to achieve optimal fit, rigidity, and repeated positioning;
Installation prompt:
Use machine tools with random wrenches and appropriate torque specifications to avoid deformation or loss of accuracy caused by overtightening.
If equipped with a T-shaped nut plate, necessary repairs should be made according to the size of the T-shaped groove on the machine tool; After installation, check the locking force, blade tip height, and repeat positioning.
