Centerless Grinding Services (OD)
Centerless grinding is an outside diameter grinding process. AN-Prototype provides centerless grinding services for a large number of metal parts that can be ground in a short period of time. Centerless grinding is the absolute best option if you have a large number of parts and assemblies that need to be formed and ground. AN-Prototype is very good at precision grinding the outer diameter of any cylindrical part, from stainless steel to ceramic and other exotic materials. Precision grinding machines allow us to machine standard and non-standard sizes up to 60 feet in length and 10,000 pounds in weight while maintaining tolerances up to ±.0002″. With 15+ years of experience, our experienced staff can grind diameters From 1/8″ to 16″ round bar and tubing, the finished product can be customized for a number of specific end uses.
Cylindrical Grinding Services (OD & ID)
For parts with complex geometries or critical features that cannot be ground by a centerless grinding process, Cylindrical Grinding Services (OD & ID) will be an option. AN-Prototype specializes in precision cylindrical grinding, that is, the precision grinding of the inner diameter (ID) and outer diameter (OD) of cylindrical parts, and is good at machining parts with various features, such as grooves, radii, and tapers. Precision ID/OD grinding provides better part-to-part consistency than similar alternative turning processes, especially for parts with dimensional, roundness, concentricity and surface finish requirements.
Surface Grinding Services
Our surface grinding team has the experience and knowledge to assess the most appropriate method of performing a surface grinding operation and tailor the workflow to the needs of each part. We can take on the challenge of large surface parts with tolerances of +/- 0.001mm. Surface grinding is very suitable for materials with large surfaces and reduces costs by performing surface grinding on multiple machines at the same time. We welcome the challenge of surface grinding requirements across all industries, from simple or flat grinding to the most complex parts.
Honing Service (ID)
Honing is a method of manufacturing parts that require the most precise tolerances and finishes. Honing is used to meet tolerances when workpieces are assembled in high-precision systems such as internal mold cooling core pins. Honing also improves the geometry of the surface of a part and can perfect the surface finish of a pipe or hole. The honing head rotates in the hole while simultaneously moving in and out of the workpiece, removing stock and providing a high part surface finish.
AN-Prototype’s honing capabilities range from large machine components to complex valves and gears to tight tolerances down to +/- 0.0005 inches (±0.001mm).
Typical Precision Grinding Materials
AN-Prototype’s CNC machine shop can machine virtually any engineered material including plastics, metals, alloys, ceramics and wood, below is a list of our standard milling materials available.
Brass / Bronze
Application industry of precision grinding
The ejector rod and core rod in the injection mold are very important, too tight or too loose will directly lead to the failure of the final product. The diameter tolerance of the core pin after precision grinding can reach ±0.001mm, so that its surface will be smoother, reduce friction, increase durability, ensure the normal operation of injection molding, and manufacture qualified injection molding products.
The components in a car work with each other in motion, requiring high tolerances. Even the slightest protrusion or rough surface increases risk and reduces fuel efficiency. After precision grinding, the surface of auto parts is very smooth, which can ensure coordination with other parts and reduce friction.
Medical equipment, surgical equipment such as drills, scalpels and dental tools, are in direct contact with the human body and must maintain high precision and accuracy on their surfaces. To ensure the exact gauge, sharpness and finish of medical devices, this requires precision grinding processes. Grinding creates smoother part surfaces, reducing the risk of friction or infection
Machines and tools that perform manufacturing and machining processes require maintenance, repairs and parts replacement from time to time after long periods of operation. Precision grinding is used to maintain the performance of machining and manufacturing equipment, including reconditioning existing tools or producing new tools to special specifications. New grinding technologies such as centerless grinding are also impacting the manufacturing and machining industries by reducing the cost and material waste required to achieve higher precision parts.
Aerospace parts are several grades higher than those of other industries, and it is the industry with the most demanding parts quality requirements. Maintaining normal operation even under extreme conditions will reduce the risk of failure or failure to zero. For example, manufactured rivets and bolts must match every detail of the original design, which requires precision grinding processes such as thread grinding. Grinding also provides precise dimensions and finishes for engines, control system parts, and hydraulic or pressurized components.
Robots are gradually replacing human labor and are used in various industries, even in some very harsh environments, which requires higher and higher requirements for parts. The parts in the robot work with each other and coordinate with each other. The precision grinding process can improve the smoothness of the surface of the part and reduce the risk of downtime.
