Cylindrical Grinding

Cylindrical grinding processes—including outside diameter (OD) grinding, inside diameter (ID) grinding, plunge grinding, and centerless grinding—are among some of the most common grinding processes used in precision machining. A cylindrical grinder is capable of manufacturing precise shapes and finishing materials with a superior surface quality.

That’s especially important when machining workpieces with cylindrical surfaces and tight tolerances for noise avoidance, such as e-motor rotor shaft, turbine shafts, input shafts, stub shafts, and so on. A good cylindrical grinder can meet extremely stringent dimensional requirements, surface finishes, and outside/inside diameter characteristics.

But while internal and external cylindrical grinding are among some of the most common grinding processes in many industries, they can also prove among the most difficult. The constant rotation of the workpiece and abrasive grinding wheel, combined with large contact arcs between the two, spindle speed, and the specifics of workpiece and bore geometry can lead to noise characteristics that proves difficult to control.

It’s not enough to have the best CNC cylindrical grinding machines. You also need a team with the experience to proactively solve problems before they harm production.

Since 1982, Systrand has specialized in precision machining. Over the course of the last 40 years, high-performance gears and shafts have become increasingly important to the automotive industry—and to us. We were among the first U.S. manufacturers to supply high-precision hybrid and electric (HEV/EV) gears. Today, we have millions of hybrid and electric vehicle gears and shafts in the field. More importantly, we’ve invested in teams that can deliver. We have the tools, processes, and talent in place to help our customers find better solutions.

Our production and design teams benefit from the latest CAD/CAM software; modern, flexible, and scalable CNC machines; and performance-accelerating Zeiss coordinate-measuring machines (CMMs). Our internal tool room department can expedite any part-specific machining work we need to compress timing. In our metrics and results driven production environment production, we can include an advanced 100% noise signature analysis on critical components, capable of isolating ghost order noise and other extremely subtle sources of unwanted vibration.

“Quality” isn’t just something for the Quality Department to worry about. It’s a commitment threaded through every office and workstation. At Systrand, we are a tier 1 supplier with IATF 16949 and ISO 14001 certifications. Our quality systems, processes, and entire organization are committed to ensuring quality for our customers.

Over four decades, we’ve invested and reinvested in the tools and talent that are vital to our customers’ success. That includes a world class operating system of monitored performance and a structured approach to problem solving proven to ensure reliable manufacturing.

These are metrics/results driven systems, built on Lean Manufacturing principles and Six Sigma methodology, and take into account activity-based costing and overall equipment effectiveness (OEE) while maintaining low- to zero PPM. Those systems form a foundation from which we can pursue continuous improvements and cost savings for our customers.
