Post grinding Heat Treatment. Grinding of a ceramic can affect its surface roughness and may induce surface defects, both of which can adversely affect the flexural strength of alumina (Ref 3, 4). However, grinding is a necessary procedure which imparts dimensional accuracy to an otherwise defect free but uneven as sintered ceramic surface.

How Rolled and Ground Ball Screws Stack Up. Grinding also lets manufacturing partition the job into smaller steps and insert procedures, such as QC, restraightening, or heat treating to release material stresses. The order of steps can also be adjusted. For example, threads can be .
Grinding steel ball heat treatment refers to the technique of heating billets to a certain temperature, maintaining some time and cooling at different speeds. Grinding steel ball heat treatment typically includes heating, insulation and cooling processes. These steps connect with each other and can't be interrupted. Wherein, heating is an important step. There are many heating methods for heat treatment.

How a Ball is Made. Heattreating: Carbon steel balls are next carburized and hardened. Heat treatment imparts the desired hardness and case depth. Descaling: This step removes the residues and byproducts from the heattreating process. Hard Grinding: Slow, meticulous grinding assures proper sizing and sphericity, with tolerances as close as ±.0001".
The goal of this work is to model the temperature distribution, phase transformation and residual stresses induced during the heat treatment of 3 and 5 inches diameter grinding balls. In the first step, the radial distribution of temperature inside the balls was calculated and validated experimentally.

Some heat treatment processes are designed to treat the entire surface of a gear, while others are selective in nature. Induction hardening or selective heating may be employed to harden just the gear teeth only, which can be an effective method of reducing the distortion in a gear.
Heattreatment is followed by grinding operation whereby the precision of balls is increased. The balls are then lapped polished to give the required surface, roundness and precision integral with VIKMAN STEEL BALL INDUSTRIES.
Heat Treatment or NickelChromium White Irons. Nickelchromium white iron castings are given a stressrelief heat treatment because, properly made, they have a martensitic matrix structure, ascast. Tempering is performed between 205 to 260°C (400 to 450°F) for at least 4 h.
