Multi-Station 3D CNC Router: Solving Small Statue Mass Production

Three-Dimensional Processing of Small Wooden Statues is a core, high-precision technique within the woodcarving industry. It is widely applied to Buddhist and religious effigies, small-scale 3D figurines, and intricate woodcraft carvings. The primary pain point in this industry is not achieving fine detail on a single custom piece, but rather maintaining precise control over wood characteristics during mass production while ensuring large-scale manufacturing efficiency.

This project showcases how a Multi-Station 3D Woodworking CNC Router addresses these industry bottlenecks, providing an efficient and highly reliable solution for woodcarving and statue manufacturers worldwide.

Ⅰ.Project Background and Customer Requirements

With years of deep-rooted experience in the woodcarving industry, the client specializes in the custom design and mass production of various small-scale wooden statues with complex geometries. Featuring three-dimensional forms and intricate detailing, their products are successfully exported to overseas markets. However, with the surge in custom market demand and the increase in high-volume factory orders over the past two years, their original production model could no longer keep pace with market needs. The client was in urgent need of a brand-new machining solution capable of achieving large-scale, standardized production of complex statues without sacrificing carving precision.

The client's previous production setup combined manual fine carving with single-head, 3-axis CNC routers. While manual carving delivered meticulous details, it made mass production impossible. Conversely, ordinary CNC equipment allowed for mass production but failed to recreate complex 3D curved surface effects, limiting its utility to small-batch custom orders. Addressing the client's core challenges—difficulty in batch processing complex 3D small wooden statues, poor finished product consistency, and high labor costs—the client explicitly put forward three major upgrade requirements:

First, increase workshop production capacity. Expand the ability to take on large-scale custom orders without increasing the number of machine operators.

Third, improve workshop production efficiency. Reduce processes such as manual flipping and secondary positioning, lower the scrap rate, and enhance the overall production efficiency of the workshop.

Based on the client's three core requirements, we introduced a targeted multi-station, multi-axis simultaneous woodworking solution. From equipment structure to processing craftsmanship, this solution perfectly matches the client's needs for the mass processing of small wooden statues with complex geometries.

It can accomplish many tasks that ordinary ATC CNC routers cannot, making it ideal for the high-precision, multi-style mass production of small wooden statues.

This solution completely revolutionizes the outdated traditional production mode of processing single pieces one by one. By utilizing the equipment's 10 independent and identical processing stations, it achieves simultaneous machining of multiple workpieces. The entire process requires only a single clamping to complete all carving stages at once, fundamentally altering the traditional logic of single-piece processing and perfectly matching the client's production needs for high-precision, large-scale mass manufacturing of small statues.

1.Core Product Configurations:

• 10-station independent spindle configuration, where each station is equipped with an independent spindle and rotary axis, allowing for simultaneous three-dimensional shaping, fine cutting, and other operations on 10 workpieces. This compresses orders that originally took several days down to just a few hours.

• 4-axis simultaneous machining capability: Distinguishing itself from simple 3-axis machining, this machine possesses true 4-axis simultaneous capability (X, Y, Z + rotary A-axis). This means the workpiece can rotate continuously during the carving process while the spindle performs multi-angle, three-dimensional cutting. It effortlessly completes various complex curved surfaces and irregularly shaped 3D profiles, perfectly matching the high-precision fine machining needs of all kinds of small wooden statues with complex geometries.

• Heavy-duty structured body: Simultaneous multi-spindle operation generates a heavy cutting load. The machine adopts a heavy-duty, one-piece fully cast bed and a thickened cast-iron gantry to ensure bed stability and zero vibration during high-load, high-speed machining.

Ⅳ.Workpiece Processing Workflow

1.Design and Programming:

The operator uses common design software such as Artcam or Solidworks to complete the 3D modeling, and then generates the machining toolpaths via CAM software while simultaneously configuring the processing paths for all 10 workpieces. Once the program is verified through simulation, it is imported into the control system via a USB flash drive.

2.One-Time Workpiece Clamping:

The operator secures the 10 wooden statue blanks individually onto the chucks of the rotary axes. Depending on the statue's shape and specifications, tailstock live centers are used as auxiliary supports to ensure firm and rigid clamping. Subsequent mass production requires no repetitive adjustments, saving a tremendous amount of time.

3.Tool Setting and Startup:

A tool setter is used to quickly define the machining origin for each spindle. Since the same program is used, the operator only needs to precisely set the origin for a single reference workpiece; the system automatically compensates for the offsets across the remaining spindles, ensuring the machining positions for all 10 workpieces are perfectly identical.

Launch the program, and the machine will begin automated processing.

4.Four-Axis Simultaneous Automated 3D Carving:

Once the program starts, the machine operates entirely automatically without requiring manual supervision. Ten stations work simultaneously, utilizing the 4-axis simultaneous rotary carving function to complete the 3D machining of all workpieces in a single pass. During operation, the workpieces rotate continuously while the spindles cut into the wood from multiple angles. This allows the full 3D geometry to be formed all at once, eliminating the need for mid-process secondary clamping or re-calibration.
