Typically, precision metal grinding processes remove small amounts of material to achieve an excellent finish or tight tolerance dimensions on part surfaces. There are different types of grinding services and machines and various scenarios where precision metal grinding is required.
What Is Precision Metal Grinding?
If you’re in the business; where you make products using small metal parts of different shapes and sizes, you may wonder whether precision metal grinding services would benefit you.
In the abrasive cutting method we use for 2-axis cutoff, metal grinding utilizes an abrasive wheel (or wheels) to erase material from work pieces.
In reality, grinding is often considered a subset of cutting & vice versa since every abrasive grain on a grinding wheel works. Also, grinding services ensure a microscopic, sharp cutting edge that shears a little chip from a part surface.
Why it is the best solution?
It is the best alternative while turning or if other machining strategies are not available:
- Due to the kind of material
- Because the surface finish need
- When generating little diameters
- When faced with tight tolerances
For instance, when any parts are made of steel, molybdenum, or tungsten, turning tools aren’t powerful enough to cut & shape those hard materials. Grinding services also work better than milling on rigid materials.
Turning machine manufacturers might claim their equipment can achieve a surface finish of Ra 8 µin (0.20 µm) to Ra 16 µin (0.41 µm), depending upon the tools, speeds & feeds. However, when surface finish is essential to functionality, a ground finish is the gold standard to which other strategies aspire.
Grinding services can make very shallow cuts — for example, overcoming a part diameter by 0.0005″(12.7 μm). In the hands of a professional, precision metal grinding can achieve sub-micron-level tolerances & surface finishes on even the little tube and wire diameters.
All that being said, how do you know which of the grinding services or methods may be appropriate for your specific application? And how do you ensure you get the best results?
How Does The Surface Grinding Procedure Achieve Parallelism & Squareness?
At its most initial process, precision surface grinding is utilized to achieve two things: to generate cubic shapes of metal square and parallel. Also, it is Utilized for various applications, but typically fixtures, molds, and dies, surface grinding services seem simple at first look.
But look deeper into the scenario, and you’ll find more to mastering surface grinding services than meets the eye.
Applications for Precision Surface Grinding services:
For six-sided cubic rectangular and square pieces of metal, precision surface grinding services enable you to generate each side square and parallel to itself or a reference surface. These square or rectangular blocks are utilized in place on the grinding table by magnets so that you need one flat surface against another flat surface.
Surface grinding can be invaluable for applications like dying manufacturing from that critical foundation. The positional accuracy needed by dies used in extrusion and injection molding means the dies should be square to the outside of the center. It is here that precision surface grinding services deliver.
Surface grinding services can also be employed on rods, although not to generate the outside diameter of a round rod; for that task, OD grinding (also known as cylindrical grinding) is utilized. However, the surface grinding process can make the two ends of a rod accurately perpendicular to the outside diameter.
Here, V-blocks are utilized to position rods for grinding purposes. A round rod is fixed into the V-shaped cavity, and a clamp grasps the rod vertically. From there, precision surface grinding can be employed to grind the top of the rod to a dimension that is accurately square to the outside diameter.
Different Sizes of Surface Grinding Machines:
The surface grinding concept is similar no matter the size of the part to be ground. However, as with various machine tools, the size of a surface grinding machine consists of various sizes, such as; small to very, very large.
As surface grinders are significant, there are various trade-offs for tolerances. However, where you have a huge part, it is perfectly served by surface grinders’ capabilities on the wide end of the spectrum.
The Blanchard grinder is the considerable end, an older technology considered surface grinding, although its rotating disk might result in a different surface finish pattern.
Although there is manual surface grinding equipment, an essential feature of surface grinding services is precise, repeating mitigation of small increments of material by machine. Here, the less you mitigate, the better the surface finish and the better the dimensional accuracy will ensure.
It is not advisable to remove an incredible amount of material thickness in one pass because it will generate a bad surface finish. Furthermore, applying that kind of stress on both the metal & the machine can result in poor positional accuracy. Also, it becomes the cause of the possible fracturing of the workpiece.
Instead, it is more good to make many repetitious passes, with each removing slightly enough material.
Conclusion: Our hand-picked grinding services provider:
Grinding services make watching automatic surface grinders like seeing an accurately choreographed, rapidly repeating side-to-side motion where every interval is imperceptibly moving just a bit lower into the metal part, removing a minimal amount of material with each pass.
The machines perform work with no vibration and without any noise that accompanies metal removal by turning point. There is an exception to this incremental mitigation of the material process. In the shape of creep-feed grinding, a precision surface grinding strategy is usually designed to remove a significant amount of material in one go.
However, it was quickly discovered that the rapid reciprocating motion commonly used with surface grinding was unsuitable; therefore, creep-feed grinding machines have launched with a prolonged feed rate.
