Threaded Stainless Steel Ball With Hole,Drilled Steel Ball,Blind Holes
(1) Stainless steel 201/304/316 / copper and aluminum alloy are used in the process of making threaded steel balls with holes and drill holes, which has particularly good corrosion resistance and plasticity.
(2) The hardness meets the international standard HRC25-65.
(3) The surface adopts polishing, nickel, zinc plating, etc., which has particularly good abrasion resistance, electrical conductivity, light reflectivity, corrosion resistance (copper sulfate, etc.) and enhance the appearance
(4) Steel balls with holes can be used for locks, valves, aerospace decoration, bearings, motors, perfume bottles, sprayers, body piercing jewelry
Drilled steel ball is usually made of carbon steel,aisi 201 304 316 stainless steel,copper,brass and aluminum material.
Size ranges of drilled steel ball is from as small as 3mm and as big as 50.8mm.
Steel ball with hole(s) types are:
1- Half threaded steel ball
2- Perforated threaded steel ball
3)- Single-hole steel ball
4)- Porous stainless steel ball
Thread sizes are M2 M2.5 M3 M4 M5 M6 M7 and M8.
Related drilled steel ball
1- Half drilled or half threaded metal balls.
2- Steel ball with through hole by drilled or threaded.
3- Special drilling steel ball and threading metal balls with many hole or with mixed drilled and threaded holes.
Process of Production
Shape the molding of balls with the injectiong or blowing methord
Put the shaped ball into the grinding machines to eliminate the parts
Clean the grinded plastic balls to eliminate the oil and the abrasive
Further fine lapping to reach the required size and high precision
Further process the plasitc balls to make the balls bright
Perforated steel balls can be used for locks, valves, aerospace decoration, bearings, motors, perfume bottles, sprayers, body piercing jewelry,
Steel balls that can be drilled by conventional machining techniques include aluminum,brass, plastic, soft carbon steel, 300 series stainless steel and other unhardened metal steel balls.
