Precision Grinding
Elevate with Sundi's Grinding Excellence: Our advanced grinding technology ensures unmatched accuracy and surface finish, enhancing the stability of your parts. Benefit from competitive pricing and precision engineering
What is precision grinding
Precision grinding is a machining process used to achieve high dimensional accuracy and surface finish in manufacturing. This process involves removing small amounts of material from a workpiece using abrasive cutting tools like grinding wheels or belts. Precision grinding is typically used where the tolerance of the finished product is very tight, and surface finish quality is critical
Currently, our facility is equipped with 16 surface grinders, 2 large water grinders, 2 optical profile grinders, and several cylindrical grinders. This array of advanced machinery enables us to work with various materials, including different types of steel and tungsten steel. Whether it’s square or round parts, our equipment is adept at handling diverse shapes and sizes, ensuring precision in every project.

Applications of Precision Grinding
Materials Ideal for Precision Grinding
Precision grinding is a versatile machining process suitable for a wide range of materials, including:
Tool Steel
Known for its exceptional hardness and durability, tool steel becomes even more efficient when precision ground for exact dimensions and surface quality, making it ideal for cutting tools, molds, and machinery components.
Stainless Steel
The corrosion resistance and strength of stainless steel are enhanced through precision grinding, achieving a superior finish and tight tolerances, perfect for medical devices, food processing equipment, and general metalwork.
Tungsten Carbide
This material's extreme hardness and wear resistance make it a prime candidate for precision grinding, which is essential to shape industrial cutting tools, mining machinery parts, and precision-engineered components with accuracy.
Aluminum
Lightweight yet easy to machine, aluminum benefits greatly from precision grinding, which brings out a high-quality surface finish and exact dimensions, crucial for aerospace components, automotive parts, and electronics housings.
Brass
With its machinability and good corrosion resistance, brass achieves a smooth surface finish and precision through grinding, making it suitable for decorative items, musical instruments, and plumbing fixtures.
PMMA (Polymethyl Methacrylate)
The optical clarity and light transmission of PMMA are maximized when precision ground, resulting in smooth surfaces and precise thickness for optical lenses, acrylic glass, and transparent components.
Zirconia Ceramic
Distinguished by high fracture toughness and wear resistance, zirconia ceramic requires precision grinding for the right shape and surface quality, ideal for industrial cutting blades, dental implants, and high-stress structural components.
Alumina Ceramic
With its high hardness and thermal stability, alumina ceramic is often precision ground for shaping and fine surface finishes, making it suitable for electrical insulators, wear-resistant linings, and thermal conductive components.
