SURFACE GRINDING
SEGMENTS
CATEGORY DEFINITION
Surface grinding segments are generally used to grind flat stock or flat surfaces within a
workpiece. The segment moves over the workpiece in a flat plane or vice versa.
Applications can vary from heavy, rapid stock removal to precision tolerance operations.
APPLICATIONS:
ABRASIVE GRAIN:
• Vertical spindle surface grinding
• Grinding large molds, dies and large plates
• Producing flat stock
• Sharpening knives, blades, cutlery

TROUBLESHOOTING GUIDE
PROBLEM
CORRECTION
Segment acting too hard
Segment acting too soft
Glazing and/or burning
Increase rate of downfeed
Increase table rotation speed (watch amp-meter)
Dress more frequently
Consider reducing area of table load
Decrease rate of downfeed
Decrease table rotation speed
Check for abnormal machine vibration
Choose a softer grade
Increase table speed (watch amp-meter)
• Choose 24 and 30 grit for soft and mild steels.
• Choose 36 and 46 grit for hard steels.
• Choose as coarse a grit size as possible in order to
remove stock as quickly as possible (in big chips).
• To maximize production, choose the hardest grade
possible that will not overload the machine.
It is the user’s responsibility to refer to and
comply with ANSI B7.1
