NC Centerless grinder are used for high-precision Grinding of cylindrical, conical & convex parts, especially in mass production applications. They are suitable for manufacturing items like roller bearings, pins, and shafts with tight tolerances. These Numerically Controlled Centerless Grinder machines offer automation, accuracy, and energy efficiency, making them suitable for various industries like aerospace, automotive and electronics parts.
New Smith NC Centerless grinding Machine Bed is made of high tensile strength cast iron, heavily ribbed for better vibration damping and shock absorption. Regulating wheel spindle is mounted on super precision antifriction bearings for higher rigidity with automatic separate lubrication system for grinding wheel head spindle.

Applications
Used for high-precision grinding of cylindrical, conical, and convex parts in mass-production settings — roller bearings,bushings, valve components, transmission parts, aerospace components, medical components, toolingautomotive shafts and pins with tight tolerances, across aerospace, automotive, and electronics manufacturing.
Machine Selection
For a model recommendation, send the component drawing, material, outside diameter range, tolerance, surface-finish requirement, production quantity and whether the process is through-feed or in-feed. This lets the manufacturer evaluate the correct machine and configuration.
Frequently Asked Questions
Why Choose the Smith NC200?
The NC200 gives you the grinding capacity of the CNC200 (same 100mm capacity, 500mm wheel) with numerically controlled — rather than full CNC — automation, which suits high-volume, tight-tolerance jobs that don’t require complex multi-axis programming.
What size parts can the NC200 grind?
The Smith NC200 grinds cylindrical, conical, and convex parts from 2mm to 100mm in diameter.
What’s the difference between the NC200 and CNC200?
Both share the same 500mm grinding wheel and 100mm capacity, but the CNC200 uses a full Fanuc CNC touchscreen panel for complex programming, while the NC200 uses numerical control for automated, simpler-to-operate production runs.
What motor upgrade options are available?
The grinding wheel motor can be upgraded to 30, 40, or 50 HP, and the regulating wheel motor to 3 or 5 HP, depending on your application.
