AT3 CLASS PRECISION ROTATING TOOL HOLDERS

     
               
   

KTA AT3 class Tool holders represent the highest degree of excellence and are the perfect answer to the needs of high speed and high accuracy machining. Manufactured from SAE 8620 material, these internationalquality tool holders are characterized by controlled case depth.

SAE 8620 is tough, impact resistance, highly durable and fatigue free, so very essential for revolving tooling. It is also the only alloy with the recommended nice percentage and the required carbon manganese and chromium content.

       

AT3 class accuracy results in various advantages during machining :

   Greater contact area with machine spindle, resulting in longer spindle bearing life.

   Less vibration and chatter during milling.

   Longer cutting tool life.

   Improved run out accuracy and surface finish.

   Higher metal removal rate.

   Enhance safety.

   Freedom from cracks, created by the brittleness that results from higher case depth.

   High impact resistance, not provided by lower case depth. KTA achieved controlled case depth by virtue of oxygen probe controlled carburising.

Accurate, Objective Measurement :

   The Electronic Air Gauging Systems used to measure the accuracy of AT3 class tool holders is a state-of-the art, sensitive & very precise than the Blue Bearing Or Air Column Inspection methods as both these are subjective, time consuming, inconsistent and inaccurate.

Excellent and Controlled Operating Conditions :

   AT3 accuracy is made possible by not only state-of-the-art machines like a CNC Studer Grinder and highly sophisticated and sensitive precision measuring equipment such as Stoz air electronic gauging system, Scan max-CMM. CAD/CAMS, etc. but by creating a fully air-conditioned working environment for 24 hours throughout 365 days in grinding section to control dimensional accuracies as well as repeatability.
