Maryalo Polishing
At Maryalo, our precision polishing and lapping processes
feature independent rotation of the workpiece and lapping plate,
optimizing the finishing process. As polishing progresses,
the abrasive slurry refines into finer particles,
enhancing machining precision. With micron-level accuracy,
our ultra-precision techniques set the national benchmark,
delivering exceptional surface roughness, parallelism,
flatness, and dimensional accuracy

Precision Polishing & Ultra Precision Polishing

Difference Between Precision Polishing and Ultra-Precision Polishing
Processes requiring high-precision polishing technology can generally be classified into two types: precision polishing and ultra-precision polishing. Precision polishing refers to polishing that achieves micro-scale machining accuracy of up to 1/1000 mm (millimeter). Ultra-precision polishing refers to polishing that achieves nano-scale accuracy at 1/1000 μm (micrometer), which surpasses the micro-scale range of a few microns to tens of microns. Ultra-precision polishing is commonly applied to semiconductor wafers, camera lenses, precision mechanical components, and optical parts. Maryalo’s advanced technology provides solutions in this field. Since nano-level machining accuracy is required, this polishing technique demands a controlled environment for temperature and humidity, as well as specialized tools and equipment. Without meeting all these conditions, achieving ultra-precision polishing is extremely difficult.
Precision Measurement
Precision measurement generally refers to the measurement or inspection of product dimensions and shapes that require precision machining technology and surface irregularity verification either during or after processing. With years of accumulated expertise and unique technological advancements, Maryalo provides ultra-precision lapping and polishing technology services. During processing, the following precision measurements are performed.

Flatness Measurement
Maryalo has received numerous orders for prototype and mass production products that require higher flatness precision than other companies. We own flatness measurement equipment such as laser interferometers and utilize them appropriately based on customer requirements and product specifications. In addition to flatness measurement, we also provide services such as flatness correction machining, precision machining according to geometric tolerances, mirror surface machining, and prototype production.

Surface Roughness Measurement
The surface of a workpiece is influenced by a complex wave pattern of peaks and valleys with varying heights, depths, and intervals. These fine waves are referred to as “surface roughness”, which affects product lifespan, mechanical efficiency, surface gloss, and texture. Therefore, in ultra-precision machining, surface roughness measurement is an essential evaluation method. There are two main types of surface roughness measurement: contact and non-contact methods. Since Maryalo possesses both types of measurement equipment, we can handle any type of surface roughness measurement.
