Speed up The Workhead: Sometimes increasing the rotational speed of the part will fix the problem. This is especially true if roundness issues are resulting from a harmonic, which is eliminated by changing the workhead speed. Going faster also reduces the depth of cut per revolution which often reduces grinding forces, deflection, vibration, …Web

Cylindrical grinding is the process of grinding the outside surfaces of a cylinder. These surfaces may be straight, tapered or contoured. Cylindrical grinding operations resemble lathe-turning operations. They replace the lathe when the workpiece is hardened or when extreme accuracy and superior finish are required. As the workpiece revolves ...Web

Honing is a type of abrasive process typically used to finish the interior of a cylinder. Rather than using an abrasive wheel as in grinding, a hone uses several flat stones arranged around a mandrel that moves in and out of the hole. For vertical or horizontal honing, the tool reciprocates through the hole, while in a single-pass finishing ...Web

Solution # 3: Increase Spark-Outs. Spark-outs are a period of time where the wheel is oscillating but not feeding– typically consuming 2-5 seconds at the end of a 20-second bore grinding operation. So spark-outs can occupy up to 25% of the machine cycle. Some manufacturers cast a greedy eye upon those 2-5 seconds, thinking of them as …Web

1 – Taper. Whether it is an I.D. or O.D. operation, taper is one of the most common problems in grinding and finding the cause can be tough. In some cases, it is as simple as adjusting the oscillation stroke to be longer or shorter to compensate. In others, dressing a reverse taper into the wheel may be the best way to handle things.Web

Boring machining is a subtractive manufacturing process used to make holes of all sizes with high accuracy. Boring typically follows other hole-making processes, like drilling, to enlarge holes to meet required dimensions and surface finishes. It is typically completed on a lathe using a tool called a boring bar, which is a cylindrical tool ...Web

The answer has to do with depths of cut. "When you turn or grind a part, the depths of cut could range from 50-100 microns or higher," Keshavan says. "Removing that amount of material in a short amount of time requires lot of energy, and the part heats up. Superfinishing removes 1-2 microns of stock on radius and requires less energy.".Web
