Precision Machining Services–Ultra Precision Machining Manufacturer

If your product requires a very high level of dimensional tolerance that cannot be achieved through CNC machining alone, the best solution would be ultra-precision machining. Masion can assist you in meeting your requirements by providing a one-stop service. We can start by CNC machining the dimensions based on the CAD drawings and then proceed with ultra-precision machining to achieve the desired tolerance levels indicated in the drawings.

The processes involved in ultra-precision machining typically include precision turning, precision milling, precision boring (diamond boring), precision grinding, honing, precision drilling, ultra-precision turning, mirror grinding, and polishing, among others. These processes are used to work with materials such as aluminum, copper, stainless steel, and more.

On ultra-precision lathes, we use finely ground single-crystal diamond cutting tools for micro-turning, with a cutting depth of only around 1 micron. This technique is commonly employed for machining high-precision, highly polished components, such as spherical, non-spherical, and planar mirrors made from non-ferrous materials, ensuring both high accuracy and surface smoothness.

What We Do

SurfaceMechanical Attrition Treatment（SMAT）（surface grinding)

To achieve a fine and smooth surface treatment and precise control of flat metal or non-metal objects’ flatness, dimensional accuracy, and surface finish, we utilize specialized surface grinding tools. By using a surface grinding machine to grind the surfaces, we ensure their flatness and smoothness. Typically, we maintain dimensional control within an extremely fine range, meeting precision requirements of 0.001mm. Furthermore, through surface grinding, we can achieve surface roughness levels of Ra 0.08 to 0.25μm, ensuring a high degree of surface smoothness for the components.

External Grinding

External cylindrical grinding is a machining process primarily performed on an external cylindrical grinding machine, used to grind the outer cylindrical, conical, and shoulder surfaces of shaft-type workpieces. During the grinding process, the workpiece rotates at a low speed while simultaneously undergoing longitudinal reciprocating motion. After each single or double stroke, the grinding wheel moves laterally in relation to the workpiece, which is known as longitudinal grinding method. In external cylindrical grinding, the workpiece is held in the grinding machine chuck, and the grinding wheel rotates and gradually approaches the workpiece to remove excess metal material, achieving the desired surface smoothness and precision.
External cylindrical grinding is commonly used for grinding workpieces that are too long or heavy to be turned. However, it is also employed for precise and accurate surface finishing on cylindrical components such as shafts, axles, and gears, ensuring the required surface smoothness and accuracy.

Internal Grinding

Internal cylindrical grinding is primarily used for grinding the inner surface and end faces of cylindrical, conical, or other shaped bores. Internal cylindrical grinding allows for grinding of both the external surface and the internal surfaces of a workpiece, producing cylindrical surfaces with uniform cross-sections. It is used in the production of components with cylindrical shapes. The internal cylindrical grinding process is mainly employed for precision finishing of internal functional surfaces. The workpiece is held in place, and the internal surface is machined using a rotating grinding wheel. Sometimes, the workpiece itself can be rotated for grinding. Similar to external cylindrical grinding, grinding methods include taper grinding and end face grinding. The choice of abrasive grain type in internal cylindrical grinding primarily focuses on wear resistance. Internal cylindrical grinding is a common machining process. It can be used to process through-holes, blind holes, stepped holes, and more on machine tool parts. Due to its specialized approach, it is particularly suitable for machining the internal features of workpieces. The dimensional accuracy achieved in the process is typically within the tolerance range of IT6-IT7. By utilizing high-precision grinding techniques, the dimensional accuracy can be controlled within 0.005 millimeters or less.

Diamond Turning

Ultra-precision cutting is a machining method that utilizes precision single-crystal natural diamond tools to process both non-ferrous metals and non-metallic materials, resulting in ultra-smooth machining surfaces (roughness Ra 0.02-0.005μm, machining accuracy <0.01μm). Precision diamond turning is a process that involves using cutting tools with diamond tips to perform turning operations. It employs lathes or related machine tools equipped with natural or synthetic diamond tool inserts to mechanically process precision components. Sometimes referred to as Single Point Diamond Turning (SPDT), the term "single point" is sometimes nominal as radius-tipped and contour form tools are also options. Precision diamond turning is widely used in the manufacturing of high-quality non-spherical optical components made from crystals, metals, acrylics, and other materials. Diamond turning molds are commonly used for shaping plastic optical components. The optical components produced through diamond turning are utilized in telescopes, video projectors, missile guidance systems, lasers, scientific research instruments, and numerous other systems and devices requiring optical elements. Most SPDT processes today are carried out using computer numerical control (CNC) machine tools. Diamonds are also employed in other machining processes such as milling, grinding, and honing. Diamond-turned surfaces exhibit high mirror-like brightness and do not require additional polishing or finishing processes as compared to conventional machined surfaces.
