ASTRO-CUT BCL

 
Biostable semi-synthetic cutting and grinding fluid

ASTRO-CUT BCL is a semi-synthetic biostable general purpose metalworking coolant containing approximately 20% mineral oil. This product, when diluted with water, forms a translucent amber emulsion which offers excellent workpiece visibility, good lubricity, and superior cooling. ASTRO-CUT BCL is designed for the machining and grinding of virtually all metals, except magnesium, and contains chlorine as an extreme pressure additive for greater lubricity.

Biostability:
BIOSTABILITY refers to the ability of a metalworking coolant to resist extreme biological degradation. This provides extremely long sump life in a properly maintained machine tool and diminishes the possibility of "Monday Morning Odor".
 
Applications:
Designed for use in metalworking applications such as all CNC milling, turning, drilling, tapping, and grinding. ASTRO-CUT BCL is also excellent on conventional machining processes and sawing applications.

Concentration - ASTRO-CUT BCL:
  • Concentration:
4% (1:25) 5% (1:20) 6% (1:17) 7% (1:14) 8% (1:12) 9% (1:11) 10% (1:10)
  • Refractometer Reading:
2.1 2.6 3.1 3.6 4.2 4.7 5.2
An optical refractometer may be used for determining concentration. These numbers are typical and are not to be construed as specifications.
 
Recommended Starting Dilutions:
  • Centerless, ID, OD, Surface Grinding:
25:1 (4%)
  • Milling, Drilling, Turning:
20:1 (5%)
  • Tapping, Reaming, Sawing:
10:1 (10%)
 
When mixing coolant, it is best to use an automatic proportioner which accurately and thoroughly mixes coolant. Always replenish the coolant with a mixture of coolant and water, not just coolant or water. Never add coolant concentrate directly to the sump.

IMPORTANT! At concentrations below 4%, the biostability of this product may be compromised, leading to much shorter sump life. To insure maximum coolant life, sump should be thoroughly cleaned and neutralized using ASTRO-CLEAN A prior to charging machine with ASTRO-CUT BCL.
