Vertical Spindle Rotary Table Surface Grinding Machine

High-Precision Combined Vertical Spindle Rotary Table Surface Grinding Machine

I.   Benefits

1. Ultra-high machining efficiency: the "Heavy-Duty Workhorse." Ideal for rapid material removal, solving "from rough to flat" challenges with high throughput.

2. High rigidity and stability enable efficient grinding of large flat surfaces and discontinuous end faces of round or rectangular workpieces.

3. Low failure rate and easy maintenance due to standardized design of key transmission and conductive components, significantly reducing downtime and maintenance costs.

4. Wide applicability across industries such as refractory materials, air conditioning cylinders, stone, automotive, bearings, valves, saw blades, and glass. Suitable for processing various non-ferromagnetic materials including carbon steel, alloy steel, refractory bricks, ceramics, crystal, quartz, stone, and glass.

II. Features

This high-precision combined vertical spindle rotary table surface grinding machine uses the end face of the grinding wheel for grinding, offering ultra-high machining efficiency.

The machine is equipped with a round electromagnetic chuck that rotates the workpiece. The electromagnetic chuck is mounted on a sliding saddle, which moves reciprocally along the bed guideways, facilitating convenient loading and unloading of workpieces.

The column and bed are connected by a three-point adjustment mechanism, allowing the grinding head angle to be adjusted for machining concave or convex surfaces across the entire workpiece.

The grinding head moves vertically along the column guideways, driven by an AC servo motor connected to a precision reduction mechanism and ball screw for accurate feed motion.

The grinding head spindle is powered by a waterproof, high-power built-in motor and supported by high-precision angular contact bearings, ensuring high cutting capacity and stable accuracy.

Machine castings are made of HT300 high-quality iron using resin sand casting, followed by annealing and stress-relief treatments, resulting in a stable structure and excellent workmanship.

III. Advantages

1.     Z-axis Upgrade: The grinding head lifting mechanism has been upgraded from a traditional side-mounted servo motor with worm gear drive to a direct-coupled servo motor with a precision reducer and ball screw. This eliminates backlash, ensures sensitive feed without "tool drop," and is ideal for precision grinding.

2.     C-axis Upgrade: The table rotation system now uses a standard integrated motor reducer directly engaging with the large ring gear, replacing the previous custom non-standard gearbox and multi-stage transmission. This reduces the failure rate and simplifies maintenance.

3.     C-axis Conductive Structure Upgrade: The traditional carbon brush slip ring has been replaced with a Mobilon standard conductive slip ring mounted externally. Even if damaged, replacement is quick and easy without removing the table.

4.     Y-axis Upgrade: The previous long-axis-driven gear and rack mechanism has been replaced with an external motor and precision reducer directly driving a ball screw. This ensures stable operation, high precision, and easy maintenance with an extremely low failure rate.

5.     Y-axis Guideway Upgrade: The bed guideways have been optimized from a double-flat structure to a one-flat, one-V configuration, improving straightness and consistency of table movement.

6.     Industrial Design Upgrade: Benchmarked against international brands, the machine features a fully enclosed high-end CNC sheet metal design after three rounds of industrial design iterations, giving it a premium and modern appearance.

IV.  Evidence

The use of high-quality casting materials and processes ensures long-term structural stability.

Core transmission and guideway upgrades have been validated in practical applications for reliability.

Industrial design aligns with international high-end equipment standards, enhancing overall quality and user experience.
