In precision machining, grinding is the final critical process that ensures parts achieve their ultimate dimensional accuracy, geometric precision, and exceptional surface quality. Our surface and cylindrical grinding services are specifically designed to meet your most stringent requirements for flatness, roundness, and surface finish.
Surface Grinding: Ensuring Ultimate Flatness and Smoothness
Our surface grinding machines specialize in creating and grinding high-precision flat surfaces, step surfaces, and vertical side faces on various workpieces.
Core Technical Advantages
Exceptional Flatness and Parallelism
Consistently achieves superior flatness and parallelism, with precision such as parallelism up to 0.01/300mm, ensuring uniformity across mass-produced parts.
Outstanding Surface Finish
Capable of achieving surface roughness as low as Ra 0.8μm or better, providing an almost mirror-like effect. This reduces friction and enhances wear resistance and sealing performance.
Expertise in Thin-Part Machining
For easily deformable thin workpieces, we employ specialized techniques such as elastic shimming to effectively control machining deformation and produce flat surfaces.
Main Machining Scope and Applications
Types of Machining
Precision grinding of flat surfaces, step surfaces, and right-angle faces across various materials.
Typical Parts
Mold parting surfaces, machine guide rails, sealing planes, precision fixtures, bearing end caps, etc.
Material Adaptability
Efficiently processes a wide range of metals, including tool steel, stainless steel, hardened steel, cast iron, and aluminum alloys.
Value to Clients
Our surface grinding service is the ideal choice when your parts require extreme flatness, parallelism, or surface finish. It often serves as the final finishing process for critical reference surfaces, directly impacting assembly accuracy and overall performance.
Cylindrical Grinding: Solutions for Precision Cylindrical and Conical Parts
Our cylindrical grinding machines focus on high-precision grinding of the outer surfaces of cylindrical, conical, and other rotary parts.
Core Technical Advantages
Micron-Level Geometric Accuracy
Excels in key geometric tolerances such as roundness and cylindricity, with roundness precision reaching 0.003mm, ensuring smooth operation and high concentricity for shaft-type parts.
Precise Dimensional Control
Achieves strict dimensional tolerances, with outer and inner diameter grinding tolerances controllable within 0.005mm or even achieving extremely high precision of 0.002mm.
Versatility
Beyond standard outer cylindrical and end-face grinding, universal cylindrical grinders can also grind inner cylindrical holes, inner tapered surfaces, and more, offering enhanced functionality.
Main Machining Scope and Applications
Types of Machining
Outer cylindrical surfaces, outer conical surfaces, stepped shafts, shoulder end faces, etc.
Typical Parts
Transmission shafts, spindles, rollers, piston rods, precision mandrels, etc.
Industry Applications
Widely used in critical fields such as automotive (e.g., engine crankshafts), aerospace (e.g., engine rotors), and machinery manufacturing (e.g., guide rails, lead screws).
Value to Clients
Cylindrical grinding is indispensable for shaft, sleeve, and roller parts requiring extreme dimensional accuracy, geometric precision (such as roundness and cylindricity), and superior surface quality. It significantly enhances rotational accuracy, service life, and assembly reliability.
We understand that grinding often determines the final success or failure of a part. Therefore, we have equipped our facility with a comprehensive inspection system, utilizing precision measuring tools (such as micrometers, pneumatic gauges, roughness testers, etc.) to conduct 100% inspections of dimensions, geometric tolerances, and surface roughness. This ensures every delivered product fully complies with drawing requirements.
The combination of surface and cylindrical grinding capabilities enables our factory to provide comprehensive precision grinding solutions, from high-precision flat surfaces to complex rotary surfaces. Whether for single prototyping or mass production, our professional expertise and stringent quality control ensure your critical parts achieve the required precision, performance, and reliability.
