  • Product Performance

    Inverted turning is an efficient machining process for circular workpieces and is widely used in the mass production and high-quality manufacturing of round metal parts. Currently, when machining disc-type parts, one side must first be processed, then the workpiece must be removed and flipped over for machining the other side. This results in complicated procedures and low production efficiency.

    The YJ-CK40SDT opposed dual-spindle automated in-line system for disc-type parts has been developed to solve this problem. With a vertically movable dual-spindle design, both sides of the disc workpiece can be machined simultaneously. The system features a high level of intelligence, high precision, doubled production efficiency, and a footprint reduced by half.

    Features

    (1) Fully Automatic Compound Machining Process Design

    By combining upright and inverted turning, the machining of disc-type parts is integrated into a two-in-one process. This enables simultaneous four-axis machining on both ends. Together with the automatic loading and unloading module, the TrackMotion automation module, and the modular machine structure, the entire process is fully automated and unmanned. This eliminates errors caused by repeated manual clamping, ensures machining accuracy, reduces auxiliary time, and doubles production efficiency.

    (2) Integrated Opposed Dual-Spindle Design

    The dual spindles are arranged in an opposed vertical layout. The upper spindle picks up the workpiece from the loading device and completes the bottom-face turning operation. The workpiece is then transferred to the lower spindle with stable and accuratee positioning by the upper spindle. The lower spindle, in cooperation with the tool turret, completes the machining of the top face. Workpiece reversing and transfer are accomplished between the two spindles without additional mechanical devices, ensuring greater stability. This design eliminates manual flipping and reclamping, offering high machining accuracy, high efficiency, and a compact footprint.

    (3) Vertical Storage and Conveying System Design

    Traditional workpiece loading relies on manual handling, which is labor-intensive and inefficient. The YJ-CK40SDT adopts a vertical storage and conveying system. The storage bin is equipped with multiple circumferential guide rods, allowing workpieces to be stacked neatly via tipping guide rods. Through motor indexing and equal-interval timing control, workpieces are accurately conveyed to the pick-up position of the upper spindle chuck. This vertical storage design increases storage capacity per unit floor space, reduces labor intensity, and enables large-batch automated machining.

Supporting Valve Component Production: The Role of Special CNC Machines in Disc Parts Machining

What Is an Industrial Valve Special CNC Machine?

An Industrial Valve Special CNC Machine is a CNC machine designed for machining disc-shaped and valve-related metal components. Simply put, it uses computer-controlled cutting tools to shape a workpiece into the required diameter, thickness, holes, grooves, sealing surfaces, and other features.

Compared with using general-purpose equipment for every operation, a special CNC lathe can be configured around the structure and production process of specific valve or disc parts. This makes it suitable for manufacturers with repeated production requirements.

Specific Applications

This Disc Parts CNC Lathe can be used for components in water treatment, oil and gas equipment, chemical machinery, power equipment, industrial pipelines, and general process systems.

Typical applications include:

  • Butterfly valve parts: valve discs, stems, sealing areas, and connection sections
  • Ball valve components: valve bodies, connection surfaces, seats, and related cylindrical parts
  • Gate valve components: valve bodies, stems, rings, and sealing-related surfaces
  • Check valve components: discs, seats, shafts, and cylindrical connection parts
  • Industrial discs: circular plates, flanges, rings, and similar components
  • Pump and pipeline components: sleeves, rings, hubs, and connection parts

For example, a butterfly valve disc may require external diameter machining, face machining, center-hole processing, shaft-hole machining, grooves, and sealing-surface preparation. The machine can be configured around the required sequence.

Core Functions

Depending on the machine configuration, operations may include external turning, facing, boring, drilling, grooving, chamfering, threading, and machining of sealing or mounting surfaces.

When evaluating the equipment, customers should check workpiece diameter, thickness, weight, spindle power and speed, chuck configuration, tool capacity, CNC control system, machining travel, positioning accuracy, repeatability, and automation options.

For valve production, workholding accuracy and repeatable positioning are particularly important because many components contain mounting holes, sealing surfaces, and connection features that must follow the part drawing.

Why Is It Purchased?

Private Brand: Machinery distributors can introduce an Industrial Valve Special CNC Machine under their own brand through OEM/ODM cooperation. Custom options may include machine appearance, nameplates, labels, manuals, packaging, and selected technical configurations.

Bulk Supply: Equipment distributors can supply dedicated CNC equipment to valve manufacturers and machining factories with recurring demand for disc-shaped components.

Cost Optimization: Manufacturers may consider specialized equipment when repeated setup, manual positioning, multiple machining stages, or separate drilling and turning processes increase labor and production costs. A suitable machine can organize related operations into a more consistent workflow.

What Customer Problems Can It Solve?

Does the target market produce large quantities of valve discs or similar circular parts? Are operators spending too much time on repeated clamping and positioning? Do general-purpose machines require several setups to complete one component? Is manual processing affecting dimensional consistency?

A suitable Disc Parts CNC Lathe can provide a machining process designed around the geometry of valve and disc components, helping reduce repeated setup and handling.

OEM/ODM Support

OEM/ODM cooperation may include spindle and chuck configuration, CNC system selection, tooling, hydraulic or pneumatic workholding, automatic loading and unloading, machine appearance, branding, packaging, technical documentation, and application-specific modifications.

When evaluating a manufacturer, customers should examine experience with valve and disc machining, engineering capability, production capacity, machine testing, dimensional inspection, spare-parts availability, installation support, and after-sales service.

The machine should be configured according to actual valve or disc drawings, material, diameter, thickness, weight, machining operations, tolerance, production volume, and automation requirements. This helps customers determine whether the equipment fits their target market and whether the manufacturer can support long-term private-label, distribution, and OEM/ODM cooperation.
