To make a truly great spindle, you must keep it straight, grind it accurately and it must have the correct metallurgy. After much trial and error, Brown & Sharpe perfected the use of nitride heat treating for their spindles. This process keeps it straight, gives it a glass-hard skin and a resilient core. There is no straightening process after case hardening, no grinding the case off one side – just a superior spindle. When you specify a Brown & Sharpe replacement spindle, you get:

• A glass-hard skin for long service life
• A resilient and tough core
• Precision-ground and lapped diameters and threads
• Brown & Sharpe engineered metallurgy
• Installed inserts and keys to save you time and money
• A spindle that will perform to the original machine specifications
