1. Introduction
The JYKB-100-DC24V-T3 CNC Torch Height Control (THC) Lifter is a precision lifting device designed specifically for plasma cutting machines. It utilizes a decelerated DC motor to accurately control the vertical movement (up and down) of the cutting torch. This lifter is crucial for maintaining consistent cutting accuracy and supports the plasma arc positioning function in CNC plasma cutting systems.
The internal transmission mechanism features a 304 stainless steel T-shaped screw, complemented by optical shafts and linear sliders at both ends. This robust construction ensures stable, reliable, and vertical operation. The entire aluminum body is refined by a machining center, guaranteeing high accuracy. Positioning and limit switches are Taiwan original HIGHLY components, further enhancing precision and reliability.
Important Note: This lifter is only suitable for plasma cutting machines.

3. Setup and Installation
The JYKB-100-DC24V-T3 lifter is designed for convenient installation. Follow these steps for proper setup:
- Mounting the Lifter: Secure the lifting body to your CNC plasma cutting machine's Z-axis assembly. The mounting holes have a center distance of 40mm. Ensure the lifter is firmly attached and vertically aligned. Refer to the dimension diagrams for precise measurements.
- Attaching the Torch Holder: Install the provided torch holder (jig) to the lifter's moving part. This holder is compatible with torches ranging from 12mm to 38mm in diameter. Ensure the torch is securely clamped within this range.
- Electrical Connections: Connect the lifter to your control system using the 4-core plug. Pay close attention to the pin definitions:
- Pin 1 (D+): Motor positive terminal.
- Pin 2 (D-): Motor negative terminal.
- Pin 3 (Zero): Positioning normally open output.
- Pin 4 (COM): Common for positioning normally open output.
- Power Supply: Connect the lifter to a stable DC24V power source. Verify that the voltage matches the specified requirement to prevent damage.
- Initial Check: Before operation, manually check the torch movement to ensure it moves smoothly up and down without obstruction. Verify that the limit switches are functioning correctly.
Note: The lifter has a built-in limit with a reverse diode for protection.
This diagram provides measurements for the lifter's length (190mm), width (82mm), and other critical dimensions for mounting and integration.
This diagram shows the thickness (59mm), mounting hole diameter (5mm), and the 40mm center distance between mounting holes, essential for accurate installation.
4. Operation
The JYKB-100-DC24V-T3 lifter integrates seamlessly with your CNC plasma cutting system to automate torch height control. Its primary function is to precisely adjust the torch's Z-axis position during cutting operations.
- Power On: Ensure the DC24V power supply is connected and active.
- System Integration: The lifter receives commands from your CNC controller to move the torch up or down. The NPN proximity switches provide feedback for accurate plasma arc positioning.
- Torch Height Control: During cutting, the CNC system, in conjunction with the THC lifter, will automatically adjust the torch height to maintain the optimal distance from the workpiece, ensuring consistent cut quality.
- Limit Switches: The upper and lower limit switches prevent the torch from exceeding its mechanical travel limits (100mm working stroke), protecting the equipment from damage.

5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your JYKB-100-DC24V-T3 lifter.
- Cleaning: Keep the lifter body, especially the T-shaped screw, optical shafts, and linear sliders, clean and free from dust, debris, and cutting slag. Use a soft, dry cloth or compressed air.
- Lubrication: Periodically inspect the T-shaped screw and linear sliders for proper lubrication. Apply a suitable lubricant if necessary, following general guidelines for precision mechanical components.
- Connection Checks: Regularly inspect all electrical connections for tightness and signs of wear or corrosion. Ensure the 4-core plug is securely seated.
- Mechanical Inspection: Check for any signs of loose fasteners, excessive play in moving parts, or damage to the housing. Tighten any loose screws and address any mechanical issues promptly.
- Switch Functionality: Verify that the upper, lower, and position switches are clean and functioning correctly. Ensure they are not obstructed.
