OD ID Grinding
At HM Manufacturing, grinding is one of our services that allows for precision products that require surface tolerances to be ground with speed, accuracy, and an exceptionally smooth finish. Cylindrical grinding is the process used when making products with high precision and tight tolerances, particularly for aerospace and automotive industries.
Cylindrical grinding is used to remove material from surfaces and shoulders of the workpiece and shows the advantage of high repeatability on tolerances and defined flank forms with closed loop corrections. OD grinding is the use of a grinding machine occurring on the external surface of an object, opposed to ID grinding which is used on the internal surface of the object. With the workpiece being spun on its axis, the grinding wheel is also being rotated as it comes in contact with the part. This effectively means the two surfaces will be moving opposite directions when in contact, allowing for products that have intricate detail and require extreme accuracy to be produced with a smooth and even finish.
HM manufacturing offers both OD and ID cylindrical grinding services that can assure a fine, quality finish on applications that require high precision shaping. Cylindrical grinding also reduces surface stress raisers and reduces fatigue cracking, extending the product life. Our grinding wheel can be shaped straight, or tapered to produce simple cylindrical shapes or it can be dressed in a complex shape to produce intricate contours on the workpiece. HM’s in house grinders can produce between 4 to 2 mirco-inch finish while holding tolerances and repeatability to +/- .000050” and a part range from ½” to 10” in diameter.
