We can machining many kinds of precision parts such as simple workpieces ,especial bolts, especial screws, especial cotter, parts with thread ,etc.. the material are made of SUS303 and 12L14 usually.
The SUS303 had better to machining than SUS304 stainless steel . both of the two typical material including identical element percentage except the "S" and "Cu" that avail to turned or cutting. we adopt SUS303 stainless steel and SUS400 hardness stainless steel to machining products usually and the best excircle dimension we machining is 20mm .ditto the SUS303,12L14 possess excellent mechanical property to machining.

SUS416 hardness stainless steel. hardness can be HRC50 through quench. cotter:the left cotter appliance to valve that is a famous brand in America.the middle pinacoid have straight knurling act on countercheck slippage.material: SUS303size: Ø9mm(excircle)*24mm(length)feature: the straight knurling be press on automatic lathetechnology: turning , cutting and press knurling |
 |
the precision turned parts by sus303: the left parts is a typical workpieces employ stainless steel that apply to the electronic appliance for family. the raw material can be circle and hexagon in common use material: SUS303 stainless steel SU316F much more anticorrosive |
 |
in fact, the left parts is a standard screw that name is shoulder screw and according to ISO7379.the pinacoid must be smooth that get to 0.8чm and the tolerance under 0.02mmproduction engineering :finish the semiproduct on automatic lathe - stamping the insert hexagon - roll the thread.material: SUS303 stainless steeltechnology: turned stamping roll thread |
 |
precision turned parts with insert thread material: SUS303feature: the excircle be precision turning .the foursquare head be milling. there sidestep .tapping insert thread through the parts.size: foursquare head: 10mm ; thread: M4 |
 |
retiform knurling blind hole nut M4*6*10 |
 |
especial stainless steel parts made to order. turned parts |
 |
left parts made of SUS416 hardening stainless steel .the hardness over HRC50 after quenched the parts in vacuum.feature : the left pinacoid be centerless grinded ,roughness over 0.2цm.material: SUS416 hardening stainless steeltechnology: turning ,milling ,roll thread and cedterless grinder. |
 |
sundry stainless steel turned parts and sundry stainless steel especial screw, nut etc..we can made-to-order by customer and have affluent experience to produce this kind of parts.left parts were processed on automatic lathe one-off. |
 |
as ditto, we can manufacture 12L14 free cutting carbon steel parts.the best excircle 20mm and the best length 80mmsurface: Zinc plate ,Nickel plate, black, undressed or according to customerheat treatment: quench, inward or according to customerproduce many kinds of turning part adopt free cutting steel 12L14 12L15 and 11L44.such as shaft, spindle, especial fastener, especial nut etc.. |
 |
isn't it like a bullet? in fact , it is a special cotter and applied to chassis assembly. the surface was plated on Nickel. there is a hole in the end side .this part will be install on the sheet and swell the hole and riveting the sheet.material: 12L14 free cutting carbon steel |
