SUBURBAN the Robbins Line Overview  
 

THE ROBBINS LINE
FORMERLY BY EX-CELL-O/ROBBINS

Overview:
This premium line of sine plates from Suburban Tool is a result of the purchase in 1989 of the Ex-CELL-O/Robbins sine plate line from Micro Precision, a subsidiary of Textron, Inc.  We have maintained the high quality of these products and follow the original  blueprints and manufacturing procedures. Changes were made only to improve the product.

The Robbins line includes sine plates for precision grinding, light and heavy machining, and inspection applications. There are many models available for single and compound angular set-ups in a wide range of sizes from 4" x 4" to 24" x 24". Within this wide range are the three different types shown below:

  • MAGNA-SINE —a magnetic type employing fine pole ceramic magnets
  • MASTER-SINE—a non-magnetic plate for inspection and light machining
  • HEAVY-DUTY —sine plates for tough machining

SUBURBAN Magna-Sine Sine Plate  
 
Features:
  • MAGNA-SINE sine plates are equipped with extremely powerful ceramic magnet chucks. Dual magnet packs provide 100 lbs. average per square inch holding power, nearly twice as much as a standard chuck!
  • Chucks have "major and minor" poles that focus the magnetic flux at the top plate. This means more concentrated, effective holding power for thick OR thin parts and less magnetization of spindles, tables, ways and other neighboring components.
  • Swivel block provides full face contact with gage blocks keeping them securely in place.
  • The roll bar is made from hardened steel, ground and lapped for straightness and roundness.
  • Exclusive locking device inside the hinge roll provides a positive lock with an expanding action. Both screws lock toward the front of the unit, pulling the top plate down on the set-up gage blocks without distortion. Hinge is made from hardened steel, ground and lapped.
  • Angular accuracy of set-ups is guaranteed to be within 5 seconds of arc up to 15, 10 seconds up to 30 and 15 seconds up to 45.
  • Side and back rail included.

SUBURBAN Master-Sine Heavy Duty Sine  
 
SINE PLATES FOR ANGULAR MACHINING
WITH POSITIVE, REPETITIVE ACCURACY

The materials for HEAVY-DUTY sine plates are carefully selected to withstand the thrust and chatter of machining cuts, during a long life of accurate service.

Features:
  • Heavy-Duty sine plates incorporate all of the features of this standard Master-Sine plates above, except the top and bottom plates are made from heavy sectioned iron castings for extra strength.
  • Top plates of both models are T-slotted for convenient clamping of work pieces. The B-12 has 3/8" slots and the B-24 has 5/8" slots. T-slots are held parallel with the sides of the top plate within 0.0005".
  • Model B-24 is supplied with a built-in ball screw elevating mechanism for safe and easy opening and closing.
  • Hand-flaked top surface.
  • Both models include extra-heavy locking straps.
