Grinding Machines
To make precision cuts that produce very fine finishes, a grinding machine removes material from a workpiece by abrasion, using a power-driven grinding wheel as a cutting tool spinning at a required speed determined by wheel diameter and manufacturer’s rating, along with a bed-mounted fixture to guide and hold the workpiece. The grinding head can be controlled to travel across the fixed workpiece, or the workpiece can move while the grinding head remains in a fixed position. Types of precision grinding operations include centerless grinding, cylindrical grinding, form grinding, surface grinding and more.

After some accidents and trials with less efficient alternatives that caused problems and delayed work, this railway group got on board with replacing their old grinding and cutting devices with new equipment that would eliminate workplace risks without sacrificing productivity.
The use of smaller abrasives and supporting tools is growing in shops that are less concerned about stock removal and heavy deburring but need to produce parts with fine finishes, want more control for less gouging of parts, and desire improved ergonomics.
A Schütte WU 305 Linear 5-axis universal tool and cutter grinder helped Micropulse enter the knee joint, hip broach and other end product market areas they could not compete in before.
From foundries to fabrication shops and final finishing, all areas of metalworking are looking to increase profitability through process efficiencies. Pneumatic tools that are appropriate for material removal can enable users to improve their productivity significantly. Here is a review of the latest air tools and how they are best suited to particular applications, along with considerations to take when specifying tools.
United Grinding focuses on the re-sharpening sector of the rotationally symmetrical tool market with its versatile Walter Helitronic Raptor. It’s the solution for shops that don’t need automatic tool support systems and automatic grinding wheel changers – but where high flexibility is required in the work area for diverse tool types.
United Grinding’s Laser Line Ultra uses an 8-axis configuration and picosecond lasers to machine complex micro geometries in cutting tools regardless of the material’s hardness.
Helios Gear Products introduces YG Tech’s Helios Hera 150 CNC machine to North America. The easy-to-program machine provides compact vertical hobbing for gears up to 6 inches (150 mm) in diameter.
