Surface grinding is an important capability that allows us to produce a unique range of products, achieving micron level tolerances and surface finishes down to Ra 8 microinch. Our combination of equipment, knowledge, and experience has made Metal Cutting a leader in the delivery of precision surface grinding services for the most demanding customer needs.
Directional Accuracy, Work Speed, and Wheel Proficiency
Our surface grinders excel in delivering tight tolerance high volume parts thanks to directional accuracy, the speed of our tables, and the selection of our grinding wheels.
Our CNC grinders provide precise control of direction and motion, allowing for automatic operation and efficient production of parts for high volume applications. To achieve maximum production flexibility and directional performance, our specialized equipment enables 4-axis precision surface grinding. In addition to our ability to grind on the x, y, and z axis, our fourth axis capability allows for full radius parts and other complex spherical, conical, and tapered geometries.
Our machines are capable of the industry’s fastest surface grinding speeds, allowing for rapid production on large orders. We also have equipment designed for the slowest grinding speeds, also known as creepfeed, allowing for the proper dimensional grinding and ideal surface finishes.
All our surface grinders feature automatic wheel dressing, providing a unique dress-while-we-grind capability. For added accuracy, our fully automatic equipment switches between rough and fine grinding downfeed and crossfeed at preset increments, resulting in fine surface finishes.
Our Equipment Advantages
Our growing inventory of state-of-the-art equipment includes the latest capabilities and programmable functionality for precision surface grinding, enabling us to achieve mirror-like surfaces and the tightest dimensional tolerances available anywhere.
Our hydraulic and ballscrew surface grinders are equipped with 4-axis automatic movement with incremental downfeed and crossfeed. Our machines traverse on precision roller bearings and hardened and grounded guideways that are pre-loaded and driven by precision ballscrews, providing excellent rigidity and precise positioning. The wheelheads are designed with a counterweighted balance system to ensure micro-downfeed accuracy. Column travels on the linear guideway system allow for smooth movement, as well as accurate positioning and high rigidity. In addition, our machines integrate well-designed ribs plus precision ballscrew and AC servo motor technology to achieve optimum speed-and-feed for creepfeed grinding.
Flooding the workpiece with coolant helps to prevent thermal damage and workpiece distortion. Load-tested spindles also help to produce accurate results. In addition, our grinding machine spindles are permanently lubricated, cartridge-sealed, and supported by super-precision angular-contact ball bearings to maintain grinding accuracy and surface finish. Our precision surface grinding equipment also features an automatic lubrication system that minimizes wear to the equipment itself while ensuring the accuracy of the machines and the high-volume parts we produce.
