Customization is a significant cost driver, with the data explicitly stating that customization is available. Buyers seeking specific color options, tailored dimensions, or unique tooling configurations should anticipate a premium over standard models. The "Color: Customized" attribute suggests that aesthetic or branding requirements can be met, but this adds to the production complexity and cost. Furthermore, the weight of the machine, which varies from 2050kg to 2900kg depending on the model, directly impacts shipping costs. Heavier machines require more robust packaging, such as the "Wooden Box" or "Plywood Case" noted in the data, and may incur higher freight charges due to their volume and mass.

The standard dimensions of the machines, such as 2190kg (likely a weight specification) or 265515201860mm (dimensions), also play a role in logistics planning. Larger machines with dimensions like 270010371312mm require specialized handling equipment and larger shipping containers, which adds to the total landed cost. Buyers should also consider the "MOQ" (Minimum Order Quantity), which is observed to be 1, allowing for single-unit procurement but potentially limiting economies of scale for bulk orders. The lead time, while not explicitly quantified in the data, is often correlated with the level of customization and the specific production schedule of the supplier in Shandong or other Chinese manufacturing hubs.

Typical Applications and Operational Capabilities

High precision manual metal lathes are versatile tools designed for a wide array of machining operations, from general repair work to specialized component manufacturing. The "Horizontal Lathe" configuration is ideal for turning, facing, and boring operations on cylindrical workpieces. The "Gap Bed" variants, with their ability to handle swing diameters up to 710mm in the gap, are particularly suited for large-diameter parts that cannot be accommodated by standard bed lathes. This makes them essential for industries such as automotive, aerospace, and heavy machinery, where oversized components are common.

The "Processing Accessory" data points to the use of "Centre CNC Lathe" and "Chuck CNC Lathe" configurations, indicating that these machines can be equipped with various chucks and centers to hold workpieces securely. The "Feeding Number" of 64 suggests a robust gear train capable of handling multiple feed rates, which is crucial for maintaining precision across different materials and cutting speeds. The "Artificial" controlling mode implies that the operator has direct control over the feed and speed, allowing for fine-tuning during complex operations where automated systems might lack the necessary flexibility.
