COPPER BALLS

These Balls are mostly used for non-bearing applications. Their properties of electricity and heat conductivity and good corrosion resistance in moisture find them allied applications in machines and components. Balls are also produce from various alloys copper as well.

Starting from the rigorous testing of the wire for all necessary parameters, balls are produced in specially designed machines called Headder, Flasher and Lapper. Apart from intermediate vigil at all operations, for all quality parameters, finished products are also tested with extremely sophisticated equipments to ensure right quality of DSP Balls.

DSP-BALLS: PRODUCTION LINES OF PRECISION BALLS

Production lines for Precision Balls are stream-lined with optimum combinations of various processes. The process given below illustrate how the high Quality of Copper balls are achieved

Heading

Wire coils are cold forged into spherical blanks, for compact structure, in semi-automatic machines known as single stroke Headers.

Flashing / Filing

Die-marks on poles and equator of headed blanks are then removed by grinding them between hardened plates of special composition, known as Flashing / Filing.

Lapping

Balls are lapped for final parameters of size, sphericity , lot variation and to surface quality in a series of specially designed machines known as Lappers.

Cleaning

Balls are then prepared for macro inspection by thorough cleaning in a especially designed cleaning machine.

Macro Inspection

Whole production of DSP-BALLS goes through 100 % inspection by well trained inspectors, under suitable magnification and light, for all surface defects.

Super finishing

Balls passed through macro inspection goes under super finishing and all Specified parameters are maintained in required tolerances as per grade to be prepared .

Guarantee Test

During production balls are inspected at every stage for fixed stage specifications, and the material is unloaded from the machines only on qualifying limits. Finally, during super finishing, parameters of geometry, lot variation and surface roughness etc. are re-ensured and detailed inspection report is prepared and supplied to the customer on demand.

Packing

They are then double packed in polythene bags, before being packed in Cardboard boxes and wooden cases. Labels carrying details of sizes, quality are properly pasted..
