    Frequently Asked Questions

    Q1: What are the primary applications of the JS Under Cylinder Type Hydraulic Machine?

    A1: This machine is highly versatile and used in the metal processing industry (for cold/hot extrusion, forging, stamping, bending), the plastic products industry (for hot pressing and extrusion molding), and the powder metallurgy field (for pressing metal or ceramic powders).

    Q2: Why is the lower built-in oil cylinder design beneficial?

    A2: The lower built-in oil cylinder design provides a highly compact structure. Additionally, it enables multiple ejection functions (such as ejection, delay, and automatic return) that facilitate the easy demoulding and removal of workpieces.

    Q3: How does the four-column structure contribute to machining accuracy?

    A3: The three-beam four-column structure is made of high-strength alloy steel with a chrome-coated surface. The four-column guidance system ensures high motion accuracy and anti-slanting stability for the movable crossbeam, making it ideal for asymmetrical products.

    Q4: Can the pressure and stroke of this hydraulic machine be adjusted?

    A4: Yes, the working pressure, pressing speed, fast down speed, and deceleration stroke range can all be adjusted to suit different production processes and requirements.

    Q5: What daily maintenance is required for this hydraulic machine?

    A5: Operators should conduct daily inspections to ensure all connections are tight, lubrication is sufficient, and the hydraulic system is free from leaks. Accumulations of dust and debris on the machine surface should also be cleaned promptly.

    Q6: What regular maintenance procedures should be followed?

    A6: Regular maintenance involves periodically replacing the hydraulic oil, cleaning the oil tank, and inspecting hydraulic components (such as oil pumps, cylinders, and valves) for wear. Any worn parts should be replaced immediately to ensure system reliability.
