Modern’s Precision Machining & Assembly Division offers unparalleled CNC grinding services to customers including cylindrical grinders, double disk grinders, centerless grinders, Blanchard grinders, and numerous other grinding methods designed to attain the ideal finish. Modern Industries can accomplish many of the post-machining grinding processes required to meet part specifications to achieve tight tolerances, uniform flatness, and mirror-like finishes, and as a final preparation for any additional finishing processes like plating or powder-coating. If you do not see the specific grinding service here that you require, please do not hesitate to contact a member of our team for more information.
From low-volume prototype projects to full-scale production runs, the Precision Machining & Assembly Division has diverse CNC grinding services to meet all project requirements no matter how strict or demanding.
Grinding Capabilities
Our in-house grinding services include:
- Cylindrical grinding: Cylindrical grinding services are performed on a cylinder grinding machine in which the workpiece is mounted on the wheel while the outer rim is machined. This is a longstanding method of achieving final finishes and tolerances that is used commonly throughout many industries for applications such as pistons, landing gear, surgical tools, electronic components, and more.
- Centerless grinding: Our centerless grinding capabilities work by placing a workpiece between a fixed blade, a grinding wheel, and a spinning adjustment wheel. There are three basic types of centerless grinding through-feed grinding, in-feed grinding, and end-feed grinding.
- Through-Feed Grinding: This process involves the workpiece being fed axially by the revolving surface of the regulating wheel. Since this allows for multiple grindings at once, this method is considered highly efficient for high-volume production runs of cylindrical components.
- In-Feed Grinding: The in-feed grinding process is useful when the workpiece is not perfectly circular but still works well with the grinding wheel provided the wheel is fed in a radial direction. This method is ideal for complex shapes that other methods can’t easily form.
- End-Feed Grinding: Our end-feed grinding process works by having the workpiece advance axially through and stop moving when it’s on the ground, End-feed grinding typically works best for tapered components.
- Double disk grinding: With our double disk grinding process, a workpiece can be machined on opposite sides simultaneously with a disk on each side removing equal amounts of material. This is common in the automotive industry for the manufacturing of components like brake pads and bearings.
- Blanchard grinding: Blanchard grinding is a highly efficient finishing process that can be applied to virtually any flat-surfaced component machined from any material. Our Blanchard grinding process uses a cylindrical grinding wheel and a vertical grinding spindle working together with a magnetic chuck. The signature result of this method is the cross-hatch pattern on the finish. This method is the leading grinding service for honing the quality and finish of large forgings alongside molds and dies.
- Surface grinding: Our surface grinding services involve a grinding machine using an abrasive wheel to grind workpieces that are mounted on a table. This is among the most common types of grinding techniques, as it is used for a wide range of industries to create a smooth and flat finish on the workpiece.
- Lapping: Our lapping services are effective at creating extremely smooth finishes on flat surfaces with adherence to strict finish and flatness tolerances. This is particularly useful in applications where subsurface damage must be avoided such as automotive pistons, gear shafts, and even surgical drills.
- Honing: Honing is similar to lapping but is more suitable for cylindrical shapes to enhance geometric precision. We accomplish this by using an abrasive material mounted on a rotating spindle, and it is commonly used for applications like air-bearing spindles and internal combustion engine cylindrical components.
Benefits of Metal Grinding
Metal grinding services from Modern Industries offer several benefits to our customers who are looking for exact finishes on their metal components. We’ve compiled an extensive list of benefits customers can expect from the various grinding techniques offered by our Machining & Assembly Division.
- Mirror-Like Finish: Grinding is one of the most efficient methods to achieve a smooth finish on a metal workpiece. If the appearance and utility of the component require smoothness, grinding will almost always be involved in some capacity.
- Remove Imperfections: The metal crafting process can leave behind metal burrs, blunt edges, and leftover metal that can impact performance or inhibit the effectiveness of additional finishing processes like plating or powder coating. Grinding can be used to remove these imperfections and help maintain the dimensional accuracy of the final component.
- Sharpened & Honed Edges: If a component calls for a sharpened edge, grinding is among the best ways to accomplish it. Grinding can create an impressive edge when it needs to, and this is particularly useful with many tool and die molds, medical equipment, and more.
- Versatility: Not all components will require the same amount of finish and polish, but grinding allows you to customize the kind of finish utilized on any part. For example, we offer selective grinding that only affects specific portions of components alongside grinding designed to change the entire workpiece. The exact nature of the finish can be determined by selecting the right grit for the grinding process. At Modern Industries, our team will work with you to find the best solution for your unique job requirements.
