Analysis of Stress Relief Technology for High-Stability Granite Bases
For granite bases equipped on ultra-precision equipment, latent problems such as precision attenuation, table micro-warping and long-term benchmark deviation are rarely caused solely by material quality or machining accuracy. Most failures stem from the gradual release of residual stress and ...Read more -
Key Material Selection Points for High-Stability Granite Bases
Granite bases serve as the core precision benchmark for semiconductor equipment, laser precision machinery, CMM inspection instruments, and new energy precision devices. Most long-term precision drift, minor deformation, and data deviation issues of equipment stem from unqualified material selec...Read more -
Maintenance Guide: How to Extend the Service Life and Flatness of Precision Granite Plates
A precision granite surface plate is often the quietest tool in a metrology room, yet it supports some of the most important decisions made there. Height gauges, indicators, comparators, fixtures, master parts, and inspection setups all depend on its flatness. Granite does not rust, does not requ...Read more -
Key Process Points of Granite Machine Tool Body Forming
1. Strict Raw Material Selection to Ensure Substrate Stability High-quality substrate is the foundation of precision forming and the key distinction from low-end industry products.

What Are the Core Advantages of Granite Machine Tools Compared with Cast Iron Machine Tools?
1. Extreme Structural Stability with Nearly Zero Deformation Cast iron contains internal pores and impurities, prone to stress deformation and table warpage under long-term load, vibration, and temperature changes, resulting in continuous accuracy deviation. ZHHIMG adopts high-density premium bl...Read more -
How Mineral Casting Improves Vibration Damping in High-Precision CNC Machining
In high-precision CNC machining, vibration is not merely a noise problem. It can affect surface finish, dimensional consistency, tool life, cycle time, and the confidence a quality team has in a process. A machine may have accurate linear scales, capable servo drives, and well-designed tooling, y...Read more -
The Role of Ultra-Precision Ceramic Air Bearings in High-Speed Laser Metrology
High-speed laser metrology makes small motion errors visible. A stage can appear smooth to the eye and still introduce velocity ripple, angular error, vibration, or short-term drift that affects a laser-based measurement result. For this reason, ultra-precision ceramic air bearings are increasing...Read more -
How to Choose Between Precision Granite, Mineral Casting, and Ceramics for Machine Bases
Selecting a machine base material is not simply a choice between three different materials. It is a decision about how a machine will behave over time: under changing temperatures, vibration, load, assembly stress, and repeated measurement cycles. For global engineering purchasers, quality manage...Read more -
Custom Granite Base Solutions for Semiconductor Inspection & Packaging Equipment
Semiconductor inspection and packaging equipment must keep mechanical relationships stable while motion systems, cameras, optics, probes, handlers, and environmental conditions are all changing around them. A small structural shift can affect focus, alignment, placement, image stitching, measurem...Read more
