Grinding heat damages workpieces. The key causes are wrong parameters, poor wheel choice, and bad cooling. Fix this by optimizing speed, feed rate, and coolant.
A grinding wheel bond is the adhesive holding abrasive grains together. It dictates the wheel’s properties, with vitrified bonds offering precision, resinoid for speed, and metal for durability.
Choose a black silicon carbide grinding wheel for softer, non-ferrous metals like aluminum or cast iron. Use a green one for hard, brittle materials like carbide.
The role of bonds in grinding wheels is to manage abrasive grain exposure for optimal cutting. Bond strength and type determine wheel grade, removal rates, and finish, with vitrified, resinoid, and metal bonds offering unique properties for specific applications.
Choosing the correct type of aluminum oxide wheel? Use brown for general grinding, white for heat-sensitive metals, and pink for durable, precision work on hard tool steels.
Master the 4 pillars of aluminum oxide wheel selection. This guide explains how grit, grade, structure, and bond determine the right wheel for your grinding task.
Select the right grinding wheels for your job. Use coarse grits for stock removal, medium for deburring, and fine grits for precision tool sharpening.
What tests are needed for an abrasive wheel? Key checks include the ring test for vitrified wheels, visual inspection for cracks, and verifying the wheel’s RPM.
High-speed grinding delivers superior precision on automotive transmission gears, reducing NVH and improving fuel efficiency by creating perfect tooth profiles.
Ultra-thin diamond blades dice silicon wafers through high-speed grinding, not cutting. Spinning at 40,000 RPM, these blades use diamond particles to grind away material.
