Granite surface plates are widely recognized as precision reference tools, serving as ideal measuring bases for instruments, precision tools, and mechanical parts inspection. In addition, granite components are extensively used as fundamental supporting structures in high-precision machinery and special processing equipment. These include worktables, guide rails, sliders, columns, beams, and bases, particularly in fields such as precision measurement and integrated circuit manufacturing.
The processing of granite surface plates requires extremely high flatness, along with additional machining tasks such as slots, grooves, side machining, and positioning holes. Granite components demand not only high surface accuracy but also precise relative positioning between guiding and supporting surfaces. In many cases, they also involve complex machining operations with embedded metallic inserts.
With the growing demand for ultra-precision machinery, the market trend for granite surface plates and components is shifting toward:
Higher requirements for flatness and dimensional accuracy
Increasing variety of products and specifications
Larger product sizes and customized solutions
Shorter delivery times and small-batch, personalized production
To address these evolving needs, this research introduces a newly designed multifunctional processing equipment that integrates rough machining, fine finishing, drilling, and slotting of granite surface plates and components. By adopting a process-concentrated approach, the equipment completes multiple operations such as milling, grinding, polishing, grooving, and drilling on five surfaces in one setup. This integrated method eliminates repeated clamping, significantly reduces positioning errors, improves machining accuracy, lowers labor intensity, and enhances production efficiency.
The equipment adopts a bridge-type structure with a movable beam and an integrated power head. Its design follows a modular and functional approach, dividing the machine into mechanical, cooling & lubrication, auxiliary, and control modules. The mechanical system itself is further divided into motion, power, support, and expansion modules. These modules can be reconfigured and combined based on product requirements, offering high flexibility and adaptability.
Through modular design and integration technology, this equipment provides:
Shorter design and manufacturing cycles
Faster production launch
Lower investment compared to traditional equipment
Strong adaptability across multiple product types
One of the critical components analyzed in this study is the movable beam, which directly affects equipment performance and machining quality. Using advanced computer-aided engineering methods and finite element analysis (ANSYS), the structural model of the beam was established and optimized. This ensures that the equipment achieves its best mechanical performance and operational stability.
The development and application of this modular multifunctional equipment represent a significant advancement in the granite processing industry. Its implementation will provide reliable support for granite surface plate and component production, substantially improving the technological level and manufacturing capability of the sector.
