Detailed Introduction to Face Milling Machine Table Material
Material Composition and Heat Treatment
Face milling machine table is usually manufactured from high-strength cast iron HT200–300. The working surface hardness ranges from HB170–240, ensuring durability during continuous use. To stabilize precision, castings undergo artificial annealing at 600–700°C followed by natural aging for 2–3 years. These treatments relieve internal stresses and enhance wear resistance.
Accuracy Standards
The Face Milling Machine Table must meet strict accuracy requirements. According to national standard measurement verification regulations, worktables are classified into four grades: 0, 1, 2, and 3. Castings comply with HT250 chemical composition standards and undergo rigorous mechanical property testing. Internally and externally, the table must remain free from defects such as porosity, sand holes, gas pores, slag inclusions, or cracks.
Surface Treatment and Structure
Non-machined surfaces of castings are desanded to ensure a clean finish. The table design includes T-slots and holes for secure workpiece clamping and effective chip removal. Structurally, the face milling machine consists of a bed, column, slide, and spindle head. The spindle head moves vertically along the column guideways, while the assembly slides horizontally on the bed guideways, enabling precise multi-directional machining.
Applications in Machining
The Face Milling Machine Table supports diverse machining tasks, including drilling, reaming, boring, tapping, facing, threading, and milling flat surfaces. Its horizontal rotary table provides radial feed for boring large-diameter holes, external circle turning, and grooving. These tables are widely used in industries such as energy, metallurgy, mining, machinery, power generation, and defense, especially for processing box-type components.
Conclusion
The Face Milling Machine Table combines durable cast iron construction, precise accuracy grades, and robust structural features. By undergoing strict treatments and inspections, it ensures stability and performance in heavy-duty industrial applications. Manufacturers can rely on these tables to improve productivity, extend machine life, and maintain machining precision.
