Precision Machining Parts


 

Precision machining parts are metal parts processed by machine tools. 


Complete Precision Machining Solutions
Impro possesses extensive industrial experience and advanced machining equipment and technology in the area of precision machining parts. Impro’s precision machining facilities are well equipped with the most advanced devices including:   

            Multi-Tasking Turning Center           
        CNC Machining Center  
       CNC Lathes  
       Precision Honing     
       Center-less Grinding, Cylindrical Grinding and Internal Grinding     
       Deburring   
       4-Axis and 5-Axis Machining Centers
     
This allows us to handle various special processes, such as precision honing, deburring, hard turning and high-precision O.D. grinding. Together with facilities for heat treatment and surface treatment as well as our laboratories, we are able to provide our customers with comprehensive one-stop precision machining part solutions. The annual production capacity of precision machining parts exceeds 24 million pieces.
 
Rapid Product Development

With more than ten years of extensive technology know-how, we are able to shorten our product development cycles for various types of products to as short as three days. Such a short development cycle significantly reduces the product development cost of our customers and facilitates their speedy go-to-market strategies.

Special Machining Process

 
Precision Honing 

Honing hole diameters range from 3mm to 50mm, tolerance 0.005mm 

 

Deburring

We have full range of deburring capabilities including electrolytic deburring, thermal deburring and abrasive flow deburring. We employ advanced deburring technology for hydraulic, automotive and aerospace components with crossing holes and complex inner cavity to meet stringent deburring requirements.

 

Hard Turning

Our hard turning process enables us to machine parts with hardness over 58 HRC after heat treatment, maximum turning diameter of 20mm, dimensional tolerance 0.005mm, roughness Ra0.2μm

 

High Precision O.D. Grinding

The precision grinding capability is employed for shafts with diameter within 200mm, length within 400mm, diameter tolerance of 0.001mm.

 

High Precision I.D. & O.D. (Universal O.D. Grinding)

The precision grinding capability enables us to machine shafts with diameter within 350mm, length within 1000mm, roundness of 0.0004mm, and cylindricity of 0.001mm. Inner holes range from 3mm to 100mm.
