Key features for NC140
Roller gear cam drive
The NC140 uses a roller gear cam drive to control rotary movement. Combined with a 1:50 reduction ratio, this configuration supports applications that require controlled angular positioning. The relevant performance requirements should be assessed against the workpiece, fixture arrangement and machining conditions.
01
Compact table dimensions
The Ø140 mm table diameter and 110 mm center height provide the main dimensions for installation planning. The listed Ø35H7 nose diameter and Ø35H7 through-hole should also be considered when checking the mounting interface and workholding arrangement.
02
Rotary positioning accuracy
The NC140 has an indexing accuracy of 15 arcseconds and bidirectional repeatability of 6 arcseconds. Its minimum setting unit is 0.001°. These values describe different aspects of rotary positioning and should be evaluated separately against the machining requirements.
03
Air-pressure clamping
The clamping system operates at a specified input pressure of 6 kg-cm² and provides an output clamping torque of 180 N·m. The required pneumatic supply and operating conditions should be checked before installation.
04
Servo motor configurations
The listed options include FANUC α aiF2, FANUC β βis4 and Mitsubishi HG-105S. The appropriate configuration depends on the machine's servo drive, motor interface and CNC control requirements.

Applications in CNC machining
The NC140 is suitable for consideration in machining processes that require controlled workpiece rotation. Depending on the part geometry, fixture design and machine configuration, potential applications include:
- Multi-face machining: Rotate a workpiece to access different faces without removing it for each setup.
- Indexed milling and drilling: Position features distributed around a part at specified angular intervals.
- Angular machining: Set the workpiece at defined rotary positions for machining operations coordinated with the machine's linear axes.
- CNC fourth-axis machining: Add a rotary axis to a compatible machining center for operations that require controlled workpiece rotation.
- Selected five-axis machining setups: Use the rotary table as one component of a suitable machine configuration. Five-axis capability depends on the complete machine's axis arrangement, controller and other required rotary or tilting axes.
Workpiece dimensions, fixture size, cutting torque requirements and available machine travel should be checked before selecting the NC140 for a specific application.
Machine compatibility and integration
The NC140 must match the machining center's mechanical interface and drive system. Installation dimensions, servo configuration and pneumatic requirements should be reviewed before ordering.
Mechanical installation
The NC140 has a center height of 110 mm, a table diameter of Ø140 mm and a listed guide block size of 14h7. The nose diameter and through-hole are both specified as Ø35H7.
Check the mounting dimensions against the machine table, fixture design and available tool travel. Any adapter plate or modified interface should be confirmed during the engineering review.
Servo motor and CNC control
The listed servo motor options are FANUC α aiF2, FANUC β βis4 and Mitsubishi HG-105S. The specified motor interface is 90 for both the FANUC and Mitsubishi configurations.
Confirm the selected motor, servo drive and CNC control compatibility before ordering. The required connections and configuration should be checked against the machine's specifications.
Clamping and pneumatic supply
The NC140 uses air-pressure clamping with a specified input pressure of 6 kg-cm² and an output clamping torque of 180 N·m.
The machine's pneumatic supply must meet the unit's requirements. The clamping system should operate within its specified conditions.
Load and workholding
The specified allowable radial load is 40 kg, and the allowable axial load is 80 kg. The allowable workload with a tailstock is also listed as 80 kg.
Check the workpiece and fixture arrangement, load direction, center of gravity and machining conditions when evaluating these values. Load suitability should be assessed against the intended mounting arrangement and applicable technical specifications.
Workholding and load capacity
Workpiece and fixture dimensions affect whether the NC140 can be used for a particular machining task. Review the table diameter, mounting interface and required tool clearance before finalizing the fixture design.
The Ø140 mm table diameter provides the reference dimension for workholding layout. The Ø35H7 nose diameter and Ø35H7 through-hole should be checked against the intended interface and mounting arrangement.
For applications using a tailstock, the specified allowable workload with a tailstock is 80 kg. The complete support arrangement should be considered when checking load suitability.
Selection guide and custom configuration
The following information is useful when assessing the NC140 for a CNC machining center:
- CNC machine make and model, including the control system.
- Required rotary-axis configuration and machining operations.
- Workpiece dimensions, weight and material.
- Fixture or chuck specifications and mounting requirements.
- Required positioning accuracy and machining cycle.
- Available installation space and pneumatic supply.
- Preferred servo motor configuration, if specified.
These details allow the mounting interface, motor configuration, load requirements and clamping arrangement to be checked against the NC140 specifications.
For applications with non-standard mounting or workholding requirements, provide the relevant drawings and installation details for review before confirming the configuration.
