As the core component of intermittent indexing motion, this precision cam drive device is compatible with AC motors and servo motors of various brands, with a positioning accuracy of ±30 arc seconds, and can withstand 1200 kgf radial load and 1500 kgf axial load; the chemical nickel-plated rust-proof housing is equipped with a flexible shaft system and flange configuration, which can be directly adapted to the existing system without expensive modification. In addition, we also provide four precision transmission components: cam indexers, hollow rotary platforms, harmonic reducers, and planetary reducers, as well as four services: precision gear processing, CNC processing, casting customization, and FA standard parts matching, covering the entire process from core components to customized processing.
High-Precision 180DF Rotary Indexer with AC or Servo Motor Drive
The 180DF series is a high-precision mill indexer engineered for direct-drive integration, compatible with both AC and servo motors (with AC motors typically equipped with encoders). Both drive configurations deliver high positioning accuracy (under 30 arc seconds) and can be controlled via dedicated drives or integrated robot controllers.
Featuring a robust cartridge cam and cam follower configuration, the 180DF series significantly enhances overall loading capacity. This optimal mechanical design ensures high torsional rigidity and reliable inertial load handling during demanding industrial cycles.
Versatile Applications in Automation & Machine Tools
As a high-precision mill indexer driven by an AC or servo motor, the 180DF is widely utilized across CNC machine tools, automated assembly lines, and precision indexing tables. Its primary function is to provide highly repeatable, exact indexing positions to transition workpieces or processing fixtures to specified stations in automated manufacturing and assembly environments.
Flexible Motor Compatibility
To offer maximum flexibility for system integrators, the 180DF features a highly adaptable motor mounting interface. Users can easily integrate their preferred brand of AC or servo motor, allowing you to change motor specifications and brands from project to project to match existing control system standards.

Manufacturing & Production Process of 180DF Cam Indexer
To achieve the indexing accuracy (under 30 arc seconds) and high load capacity shown in the 180DF blueprint, we implement a rigorous manufacturing and quality control process for each core component. Below is the detailed production workflow:
1. High-Precision Housing Machining (FC300 Cast Iron)
- Stress-Relief Annealing: The heavy-duty housing casting (FC300 grey cast iron) undergoes a thorough stress-relief heat treatment to prevent any micro-deformation during long-term operation.
- CNC Boring & Milling: The housing is machined on high-precision CNC horizontal machining centers. The critical 180 mm center distance (the distance between the input shaft and the output flange axis) is bored with a strict tolerance of +/- 0.01 mm. This precise distance is vital to ensuring the optimal preload between the cam and followers.
- Multi-Face Mounting Holes Tapping: All mounting faces, including the 16-M16 x P2.0 x DP30 tapped holes on the side and the 8-dia 18 through-holes on the base, are drilled and tapped in a single setup to guarantee perpendicularity and pitch alignment.
2. Globoidal Cam & Input Shaft (dia 60h6) Processing
- Material Selection: The input shaft and globoidal cam are forged from high-grade alloy steel (typically 20CrMnTi or GCr15) to withstand intense inertial loading.
- 5-Axis CNC Cam Grinding: The complex globoidal track profile is milled on a 5-axis CNC machining center. After rough milling, the component undergoes carburizing heat treatment to achieve a surface hardness of HRC 58-62 (while retaining a ductile core for impact resistance).
- Precision Finish Grinding: The input shaft is ground to a strict dia 60h6 diameter tolerance to ensure a seamless fit with the drive motor or coupling. The 18N9 keyway (7 mm depth) is precisely broached, and the cam rib undergoes final precision grinding to eliminate surface irregularities, ensuring smooth, vibration-free indexing.
3. Output Flange Turret (dia 250h7) Turning & Drilling
- Turning & Centering: The output shaft turret (medium carbon steel/alloy steel) is precision-turned. The locating pilot diameter is ground to dia 250h7, and the inner pilot bore is ground to dia 90h6 to guarantee concentricity and minimal axial/radial runout.
- PCD Drilling: On a vertical CNC machining center, the PCD 150 mounting pattern is drilled and tapped with 6-M16 x P2.0 x DP22 holes, allowing customers to securely bolt their dial plates or rotary tables.
4. Zero-Backlash Assembly & Preload Calibration
- Follower Press-Fitting: High-precision needle roller cam followers are carefully press-fitted into the output turret slots.
- Preload Adjustment: The input cam shaft and output turret assembly are integrated into the housing. Our assembly technicians adjust the eccentric bearing retainers to finely tune the 180 mm center distance.
5. Final Testing & Quality Inspection
- Dynamic Running-in: Each assembled 180DF indexer undergoes a no-load and loaded running-in test to monitor operating noise, vibration, and temperature stability.
- Accuracy Verification: A laser interferometer is utilized to verify the indexing repeatability and dwell accuracy before packaging and shipment, ensuring every unit meets the blueprint specifications.
FAQ
Q: How do I choose between an AC motor and a servo motor for driving the 180DF mill indexer?
A: The choice depends on your motion profile and budget:
AC Motor (with Encoder): Best for fixed-station indexing with uniform dwell times. It is a cost-effective, highly reliable solution for standard repetitive cycles.
Servo Motor: Ideal for flexible indexing where you need variable dwell times, programmable angles, high-speed positioning, and rapid acceleration/deceleration. It allows you to customize the indexing program directly from your CNC or PLC.
Q: Can the 180DF mill indexer be integrated with any brand of servo motor?
A: Yes. To ensure maximum compatibility for global system integrators, the 180DF features an adaptable motor mounting interface. We can customize the motor adapter flange and input shaft coupling to match your preferred servo motor brand (e.g., Yaskawa, Siemens, Mitsubishi, Panasonic, Delta, etc.).
Q: What are the lubrication and maintenance requirements for the 180DF series?
A: The 180DF utilizes a fully enclosed oil-bath lubrication system to minimize friction on the internal cam-follower mechanism. We recommend using high-quality extreme-pressure (EP) gear oil (typically ISO VG 150 or VG 220). The lubrication oil should be replaced after the initial 500 hours of run-in, and subsequently every 3,000 to 5,000 hours of operation, depending on your duty cycle.
Q: Can the 180DF indexer be mounted in any orientation?
A: Yes. The 180DF is designed with multi-face mounting capabilities, utilizing the side mounting holes (16-M16 x P2.0 x DP30) and base holes (8-dia 18) shown in the drawing. However, your mounting orientation (horizontal, vertical, or inverted) directly affects the location of the oil oil-fill, drain, and sight level plugs. Please specify your mounting configuration during the inquiry phase so we can pre-configure the oil plugs correctly.
