Automatic Tool Change Three-Sided CNC Boring And Milling Machine

In industries like valve manufacturing, pump production, and pipe fitting processing, many core components (such as valve bodies, pump housings, and flange pipe fittings) require multi-sided hole machining with high precision. Our Automatic Tool Change Three-Sided CNC Boring and Milling Machine addresses this demand by integrating three-sided simultaneous processing, automatic tool changing, and flexible workpiece adaptation—redefining efficiency and accuracy for multi-process, multi-side machining tasks.

Unlike traditional single-side boring machines or manual multi-clamping setups, this machine’s advantages are tailored to solve the unique challenges of multi-side component processing:

1. Three-Sided Simultaneous Processing: Cut Time by 1/3Equipped with three independent spindles, it can machine the front, side, and adjacent surfaces of workpieces (e.g., valve bodies, pump casings) at the same time. For example, when processing a gate valve body, it can complete boring of the inlet/outlet holes (front), stem hole (top), and flange mounting holes (side) in one clamping—eliminating the need for 2-3 rounds of repositioning and clamping. This slashes total processing time by over 30% compared to sequential single-side machining, critical for batch production.

2. Automatic Tool Change (ATC): No More Manual Tool SwapsIntegrated with an automatic tool changer (a key upgrade from basic three-sided boring lathes), it can switch between boring tools, drilling bits, tapping tools, and milling cutters automatically based on programmed processes. For instance, when machining a flange pipe fitting, it can first bore the inner hole (with a boring tool), then drill the flange mounting holes (with a drill bit), and finally tap the threads (with a tap)—all without manual tool adjustments. This not only reduces labor input but also avoids tool-setting errors caused by human operation.

3. Movable Workbench + High Rigidity: Flexibility Meets Stability

   • The movable workbench supports both rotation and linear adjustment, easily adapting to workpieces of different sizes (from small check valves DN40 to large pump housings Φ1025mm) and shapes (square valve bodies, cylindrical pump casings). Loading/unloading is simplified—no need for custom fixtures for every new part.

   • The bed is built with high-strength structural design, and the precision transmission system (gear speed change with 2-4 speed gears) ensures no vibration during high-speed machining. This combination guarantees that even when processing three sides simultaneously, key precision indicators (coaxiality ≤0.1mm, parallelism ≤0.1mm) remain stable, avoiding assembly issues caused by dimensional deviations.

4. All-in-One Machining: Boring, Drilling, Tapping, Milling in One SetupIt’s not just a boring machine—it integrates four core functions: boring (for high-precision inner holes), drilling (for mounting holes), tapping (for threaded holes), and milling (for flange end faces). Take a casting water pump housing as an example: it can mill the pump end face (to ensure flatness), bore the impeller installation hole (to ensure coaxiality), drill the motor mounting holes, and tap the threads—all in one clamping. This eliminates the need to transfer workpieces between multiple machines, reducing workpiece handling damage and improving process consistency.

This machine is not designed for general-purpose small parts or ultra-precision aerospace components—it excels in machining industry-specific multi-side components that require both efficiency and precision:

• Valve Manufacturing: Processes gate valves, butterfly valves, check valves (DN40-DN200+). For butterfly valve bodies, it ensures the coaxiality of the stem hole and flow channel hole (≤0.1mm), avoiding valve leakage caused by misalignment.

• Casting Water Pumps: Handles pump housings of various diameters (Φ460-Φ1025mm). It machines the pump’s water inlet/outlet holes, bearing mounting holes, and motor connection holes simultaneously, ensuring the pump’s operational stability (no jitter from uneven hole positions).

• Fire Protection Industry: Produces fire hydrants and water supply/drainage facilities. It mills the hydrant’s flange end face (surface roughness 6.3) and bores the water flow channel, ensuring tight connection with pipelines and no water seepage.

• Pipe Fitting Industry: Machines flange pipe fittings and elbow connectors. It drills flange mounting holes (position accuracy ≤0.2mm) and bores the inner pipe hole, ensuring the flange and pipe are perfectly aligned for easy on-site installation.

We offer four models (YCⅢC300HT to YCⅢC800HT) with clear differentiation in processing range and power, ensuring you can match the right machine to your component size:

• Reduce Scrap Rate: One-time clamping avoids dimensional errors from repeated positioning—scrap rate for valve bodies and pump housings can be reduced from 5-8% (manual clamping) to ≤1%.

• Save Workshop Space: Integrating four functions (boring, drilling, tapping, milling) into one machine replaces 2-3 traditional devices, saving 50% of the floor space required for multi-process setups.

• Lower Skill Threshold: With a user-friendly CNC system (optional Nanjing Huaxing/Guangzhou Shukong servo/stepping systems) and automatic processes, operators only need basic programming training—no need for senior technicians skilled in multi-machine operation.

Whether you need to process small check valves (YCⅢC300HT), medium pump housings (YCⅢC400HT), or heavy-duty flange pipe fittings (YCⅢC800HT), we can further customize:

• Tool changer capacity: Upgrade to a 12-tool or 16-tool ATC for more complex multi-tool processes.

• Workbench fixture: Customize dedicated fixtures for non-standard components (e.g., special-shaped valve bodies).

• Control system: Match your existing workshop’s CNC system brand (Nanjing Huaxing/Guangzhou Shukong) for seamless integration.
