🔑 Key Features
|
Feature |
Description |
|
🔧 Universal Design |
Compatible with a wide range of CNC turning machines |
|
⚙️ Solid Round Body |
Unlike split bushings (e.g., Type B), J types are solid for enhanced durability and stability |
|
🧰 Flat-Shank Tool Compatibility |
Specifically crafted for tools with flats on their shank - ideal for drills, boring bars, and shank-type tools |
|
📐 Diameter Range |
Supports wide ID variation to match various tool sizes |
|
🔒 Clearance Holes for Set Screws |
Enable direct locking onto the tool’s flat surface, preventing rotation and boosting grip strength |
|
🧩 Stepped Head Design |
Eases removal from tool holders or turrets, minimizing downtime during tool changes |
|
⚒️ Enhanced Hardness |
52–55 Rockwell C for longer tool life and reduced costs |
🧱 Material & Construction
v Built from high-strength alloy steel for durability under heavy load
v Precision-ground to maintain tool concentricity and reduce vibration
🧰 Applications
v CNC turning centers and lathe blocks
v Tool holders with standard bore sizes
v Machining setups requiring frequent tool change and versatility
🔧 Practical Advantages
v Secure Clamping: Eliminates tool slippage thanks to set screw contact with the flat.
v Quick Removal: The stepped head makes tool changes fast and efficient.
v Rigid & Precise: Solid body ensures stability, reducing vibration during operations.
🔎 Why Choose J Bushings? J Bushings offer solid-body strength, precise flat-shank tool locking, and fast removal for efficient CNC machining.
