NFTDP80 High-Frequency Servo Punching Cylinder
An NFTDP80 short-stroke servo punching cylinder configuration for cyclic axial processing. Catalog force options are 11 / 20.3 kN; tooling, material and repetition rate determine the released working duty.
- Short working stroke — 20 mm catalog stroke. Define tooling clearance, actual cut travel and overtravel reserve.
- Configuration-specific force — 11 / 20.3 kN options; do not combine unrelated motor and reducer combinations.
Configuration options
20 mm catalog stroke. Define tooling clearance, actual cut travel and overtravel reserve.
Working cycle
Approach, working movement, dwell and return reviewed together.
Mechanical integration
Mounting, load path and independent guidance defined for your machine.
Engineering support
Drive and feedback selection with NEFEIT.
Size the punching process
Specify material, thickness, cutting perimeter, shear strength and tooling condition. Include return resistance and stripping force rather than selecting only from nominal thrust.
- 11 / 20.3 kN options; do not combine unrelated motor and reducer combinations.
- Frequency is a working-cycle reference, not a linear speed in mm/s.
Images show the product layout and installation concept. However, the approved configuration drawing defines the assembly supplied.
Configuration specifications
| Parameter | Catalog reference |
|---|---|
| Stroke | 20 mm |
| Thrust options | 11 / 20.3 kN |
| Motor options | 400 / 750 W |
| Motor speed | 3000 rpm |
| Reduction ratio | 12:1 / 10:1 |
| Cycle-frequency reference | Confirm 4 or 5 Hz |
| Repeat positioning reference | ±0.01 mm; verify measurement conditions |
| Mounting | Front flange plate |
Catalog references apply to the stated configuration. Confirm tooling, sustained duty and calibrated measurement conditions. The heading and table differ on 4/5 Hz; confirm the required NFTDP80 cycle frequency.
Check the drawing for this product configuration
Confirm the mounting, tool interface and full movement envelope for the selected process configuration.
Mechanical drawing
Request flange pattern, body envelope, rod connection and installed length for this configuration.
Tooling support
Provide guide layout, reaction structure and axial alignment requirements.
Utilities and feedback
Confirm motor/drive, sensors, connectors and control responsibilities.
Strip punching: support the material at the die
The short-stroke actuator operates beneath a supported metal-strip die within a reaction frame. The die guides the process tool, while the feed system controls strip position.
- Calculate cutting perimeter and material shear load
- Include stripping and return resistance
- Confirm the NFTDP80 4/5 Hz configuration
Provide the inputs that define your configuration
Technical interfaces
Before you design mating parts, review the product drawing and available space with NEFEIT. The approved drawing defines the supplied configuration and mechanical interfaces.
Selection checklist
- Material, thickness, cutting perimeter and shear strength
- Cutting, stripping and return loads
- Required waveform, frequency and operating hours
- Die guidance, reaction frame and flange interfaces
The quotation confirms the mechanical, electrical, feedback and integration scope.
Product selection questions
Catalog references apply to the stated configuration. Confirm tooling, sustained duty and calibrated measurement conditions. The heading and table differ on 4/5 Hz; confirm the required NFTDP80 cycle frequency.
Support the workpiece and guide the tool independently. Review axial alignment, frame stiffness and transverse-load isolation.
Agree calibrated sensor ranges, loaded measurement conditions and trials with the actual parts. Catalog accuracy figures are configuration references.
Confirm the actuator, motor/drive, drawing, feedback, controller and tooling responsibilities for the supplied scope.
Select NFTDP80 for your machine requirements
To request a quotation, send your load, stroke, speed, working cycle and installation drawing. NEFEIT then reviews the motor, feedback and mechanical interfaces with you.
