Products Description
The portable CNC drilling and tapping machine is easy to disassemble and carry. It can be placed directly onto the surface of large and extra‑large workpieces for batch drilling and tapping, making it suitable for both indoor and outdoor use.

Core Advantages
- Manual drilling cannot guarantee drilling accuracy
- Conventional general‑purpose equipment is bulky, fixed in position, and difficult to adapt to different scenarios
- Large and extra‑large workpieces are difficult to move – conventional equipment either costs too much or cannot process them at all
- Small size, light weight, small footprint
- Modular design – can be disassembled and moved easily
- Low cost
- No clamping required
- Magnetic adhesion for secure positioning
- Integrated drilling and tapping in one machine
- Precise positioning within the effective working range
- Capable of drilling and tapping multiple holes with high center‑to‑center accuracy
- Requires only a small amount of cutting fluid

Applications
- On‑site drilling & tapping of large and extra‑large workpieces (e.g., bridge components, ship structures)
- Heavy steel structures, pressure vessels, rail vehicles
- Construction machinery, wind power towers, offshore platforms
- Suitable for both indoor and outdoor use where moving the workpiece is impractical
Selection Guide
- Workpiece size: confirm the machine's working range fits your part dimensions
- Material compatibility: carbon steel, stainless steel (magnetic adhesion required)
- Drilling & tapping capacity: max hole diameter, thread size, depth
- Portability: weight, modular design, ease of assembly/disassembly
- Accuracy: positioning precision, hole‑to‑hole center distance tolerance
- Power supply: standard single‑phase or three‑phase availability
Maintenance
- Daily: clean chips from magnetic base and guide rails; check for loose fasteners
- Regularly: lubricate moving parts (linear guides, ball screws)
- Inspect magnetic adhesion surface for debris or damage
- Check cooling system (minimal cutting fluid) – keep nozzles clear
- Monthly: calibrate spindle runout and positioning accuracy
- Store in a dry environment when not in use; protect electronics from moisture

Frequently Asked Questions (FAQ)
1. What is the maximum drilling diameter and tapping size?
Our portable CNC drilling and tapping machine can drill up to 30 mm diameter in mild steel and tap up to M24 thread. For specific models, please refer to the technical datasheet.
2. Does the machine require clamping the workpiece?
No. The machine is fixed onto the workpiece using strong magnetic adhesion. This eliminates the need for clamps, fixtures, or bolting, which is especially useful for large, heavy parts that cannot be moved easily.
3. Can it be used on non‑ferrous materials like aluminum or stainless steel?
Magnetic adhesion works only on ferrous materials (carbon steel, iron). For non‑ferrous metals, we offer an optional vacuum base or mechanical clamping kit.
4. How accurate is hole positioning?
Positioning accuracy is within ±0.1 mm over the entire working range. Hole‑to‑hole center distance accuracy can be maintained within ±0.05 mm under normal conditions.
5. Is special training required to operate this machine?
The machine uses a user‑friendly CNC interface with standard G‑code or manual data input. Basic CNC knowledge is helpful, but we provide training videos and manuals. Most operators become proficient within one day.
6. How is the machine powered? Can it run on a standard wall outlet?
The machine operates on standard single‑phase 220V or three‑phase 380V (depending on model). It draws moderate power and can be used with a generator for field applications.
7. How portable is it? What is the weight?
The machine is designed for easy disassembly into modules. The heaviest module is approximately 25‑30 kg. It can be carried by two persons and reassembled on site in less than 10 minutes.
8. Does it generate a lot of heat or require heavy coolant?
No. Thanks to intermittent drilling and built‑in mist or micro‑lubrication cooling, only a small amount of cutting fluid (or even compressed air with oil mist) is needed. No flood coolant or wastewater treatment required.
9. What happens if the magnetic base loses power during operation?
The permanent magnet base does not require electricity to stay attached – it is mechanically switched on/off. Once engaged, it remains locked even during a power failure, ensuring operator safety.
10. Can it drill and tap in the same setup?
Yes. The machine combines drilling and tapping capabilities. You can pre‑drill the hole, then change to a tapping tool (or use a drill‑tap combination) within the same program without repositioning the machine.
11. How do I maintain the spindle for long tool life?
Regularly clean the spindle taper, use high‑quality collets, and apply a thin layer of anti‑rust oil if the machine is stored for long periods. Replace worn brushes on the motor if applicable.
12. What is the typical delivery time and warranty?
Standard delivery is 15–30 days after order confirmation. We offer a 12‑month warranty on all mechanical and electrical parts, with lifetime technical support.
