The size measurement

We usually measure the diameter ,height ,thickness according to customer's drawing .

Measuremental accuracy 

● Callipers / +-0.015mm  

● Height gauge / +-0.01mm

● Ultrasonic thickness tester  / +-0.05mm

● Weight / +-1g

The accuracy control in the production 

we use pass only rules to control the diameter and height accuracy .

● Diameter accuracy : 0.2mm

● Height accuracy : 0.5mm

● Thickness accuracy : 0.1mm

we design and make the pass only rules to inspect in the production .

The sharp and curve accuracy inspection 

We use CNC milling to make a curve pass only inspection tool to measure the shape and curve

● Curve accuracy  / +-0.1mm

Three dimensional measurement 

Military part and aircraft part measurement 

Air pressure testing 

In order to check the the product without  leakage after welding ,we use air pressure to test every bowl in the water tank ,if there is bubble under the water ,we will mark the position and welding it again .

The concentricity inspection 

We design and make a special inspection tool to check the 

relative position accuracy 

● Inspection tool accuracy  / +-0.1mm

The surface effect we make 

● 8K mirror polishing / 6K mirror polishing / 100# grit brushed
