Steel angle cut cylinders, bevelled diagonals and pins are mixed with steel ball, eclipse, ballcone and satellite in the steel polishing media for various mass finishing applications to achieve uniform cleaning, metal finishing and mirror finish all over the component profile.

Spherical steel balls are the most popular and versatile shaped media used in tumblers, barrels, harperizers, centrifugal and vibratory finishing machines. However, a round steel ball cannot access grooves, corners, collars and intricate profiles. To achieve this a beveled diagonal (cylinder) or pin has to be used. Pins are also appropriate for deflashing holes and finishing intricate jewellery parts. In magnetic polishers, magnetic stainless steel pins are used as burnishing media.

~ Tolerance: Stringent dimensional controls are maintained and the tolerance on the diameters are +/- 0.15mm or +/- 0.006" (150 microns) which are amongst the best in this industry.

~ Length: STEEL DIAGONALS, CYLINDERS.Length denotes total end to end length.

~ Customised Length: Length as per specific requirements can be supplied for large orders.
The total end-to-end length will be limited to a minimum of 6 mm or 1/4" for any diameter.


~ Ends: Ends are bevelled and cut at an angle.

~  0.5mm (0.02" ), 0.8mm (0.03" ),  0.4mm (0.016" ), 0.3mm (0.01" ) Diameters:
For these sizes the cut faces are perpendicular to the length.
These are available only in stainless steel and are also suitable for magnetic polishers.


~ Steel Material:
   Stainless Steel or Inox Media, 300 series
(typically AISI 304) is the one which is most widely used for metal polishing. It has excellent resistance to rust, corrosion and wear and can be used in conjunction with chemically aggressive burnishing compounds, both acidic and alkaline. Stainless steel requires no maintenance or after care during storage, non usage or idle periods. The burnishing performance remains consistent over long periods of time and it does not require replacement as no deterioration in quality takes place. The 300 series stainless steel are austenitic and are unhardenable by heat treatment. However, some work-hardening takes place during the cold-forging process. The media is passivated after final polish.

Chrome Alloy Steel Media has low corrosion resistance and does not offer the advantages of stainless steel media. It is useful where cost saving is a major consideration or where trial or limited polishing runs are required. When not in use, high carbon high chrome steel media have to be protected against rust with appropriate chemical compounds to avoid pitting and surface wear and achieve consistent burnishing results.
The high carbon high chrome alloy steel media are thorough hardened to 58-63 HRc.

Enhance Your Component Finishing Quality With Techbuff Steel Burnishing Diagonals, Pins And Cylinders.
STEEL TAPER CUT CYLINDERS AND BEVELED DIAGONALS. The length of the diagonal provides line contact as opposed to point contact in the case of a
     sphere.
The bevelled faces provide area contact as opposed to point contact in the case of spheres.
     Because of the above two features cylindrical media offers greater contact on the component
     surface.
Pins are also useful for deflashing and cleaning holes and the areas between threads.
The taper cut face of a Techbuff cylinder or diagonal is very well smoothened to enhance
     polishing action.
STEEL PINS FOR DEFLASHING HOLES, CLEANING THREADS AND POLISHING INTRICATE PROFILES.The ends of Techbuff Cylinders, Diagonals and Pins are well deburred and radiused to access holes,
     recesses, corners and intricate designs providing proper polishing and cleaning without
     spoiling the component surface.
►  The highly polished surface of our diagonals and pins provide extremely good rolling action
     and hence excellent burnishing and finishing results.
