Mill Department

For high accuracy and quick rapids, we use Kitamura and Takisawa CNC vertical machining centers. All of these mills are equipped with automatic multi-tool turrets, programmable indexers, and a large selection of other support tooling. Some of these machines have rapids of 1400 inches per minute. They are also capable of performing high-speed rigid tapping, which allows for less manual labor.

Quality Control

Precision Specialties Co. maintains our Q.C. department in accordance
with MIL-I-45208A.  To help maintain the highest quality possible, all 
jobs are issued shop travelers to track all operations and procedures. 
 Each operation is inspected to insure that the operation has been 
completed per blue print.  All records are traceable and kept for a 
period of five years.  Our inspection  equipment is  checked and 
calibrated periodically and calibration reports  are maintained.  
Copies of our Quality Control Manual are  available upon request.

Supported By an assortment of manual equipment such 
as lathes, mills, drillpresses, grinders and a large variety of 
cutting tools, our production department is well equipped to support 
your short run, prototype and long term production needs.
