Project Overview
Wadjay M3-M16 flexible arm electric tapping machine: servo drive, 0-250rpm, 1000mm arm reach, digital touchscreen, torque protection. For steel, aluminum, stainless tapping in mold & repair shops. CE/ISO. Quote.
A Portable Tapping Arm That Replaces Bench Tapping and Hand Tapping
When a workshop handles large fixtures, mold bases, frame welds or repaired castings, moving the workpiece to a bench tapper is often slower than the tapping itself. The M3-M16 flexible arm electric tapping machine inverts that workflow: the machine comes to the part.
Built by Wadjay Machinery in Zhengzhou, this M16-class tapping arm uses a servo motor with electronic torque protection, a digital touchscreen, and an articulated arm with 1000mm working radius. The cast iron workbench keeps the column stable while the head swings to vertical, horizontal and angled holes without relocating heavy parts. On the shop floor, the difference shows up as fewer broken taps in stainless, consistent depth on blind holes, and shorter setup time on low-volume or one-off threading jobs.
In Wadjay’s own test setup before shipment, the machine runs a first-article cycle on a steel sample: speed is set on the touchscreen, the torque limit is dialed in for the tap size, and a blind hole is tapped to depth. Only after the thread gauges cleanly does the setting get saved for batch use — the kind of first-hand verification that matters more to a buyer than a “high precision” label.

How the Servo Tapping Arm Works
The value of a flexible arm tapper is not just “it moves” — it is that the servo loop controls force and position at the same time.
- Articulated positioning — the arm reaches the hole from any angle; the operator does not lift or flip the workpiece.
- Servo feed control — spindle speed and feed follow the touchscreen program instead of foot-pedal feel.
- Electronic torque protection — when thread resistance exceeds the set threshold (e.g. bottom of a blind hole), the drive limits torque so the tap slips rather than snaps.
- Depth control — automatic mode stops at the programmed thread depth, reducing over-tap and rework.
- Manual / auto modes — manual for setup and repair, automatic for repeat holes on fixtures and plates.
For stainless and hard alloys, the practical rule is: lower rpm + correct torque limit + tap-specific collet. The servo system makes that adjustment repeatable instead of relying on operator instinct.
Where It Fits on the Shop Floor
- Mold & die shops — tap threaded inserts, cooling-line holes, and side pockets without stripping the block to a bench.
- Maintenance & repair — on-site threading on frames, gearboxes, brackets and worn castings.
- Fabrication workshops — repeat holes on structural plates, enclosures, machine guards.
- Automotive & agricultural repair — cylinder heads, housing repairs, bracket retrofits.
- Small-batch production — jigs and fixtures where a CNC rotor would be overkill.
Why Buyers Choose the Wadjay M3-M16
- Flexible arm, fixed workpiece — 1000mm reach covers most mid-size parts without crane handling.
- Servo torque protection — fewer broken taps in stainless and blind holes.
- Touchscreen setup — speed, depth and direction stored per tap size; new operator ramp-up is short.
- Cast iron base + portable cabinet — stable cutting, movable between cells.
- M3 to M16 in one arm — collet change covers the most common metric thread range.
- CE/ISO export build — voltage, label and docs configurable for overseas buyers.
- Factory-direct from Zhengzhou — Wadjay Machinery Export Co., Ltd. supplies the machine with test video and technical support.

FAQs
Q1: What thread sizes can it tap?
A: M3 through M16 metric, using interchangeable collets. Special pitches and unified/UNC threads confirmed by collet standard.
Q2: Does it handle stainless steel?
A: Yes. The servo torque limit reduces tap breakage, but correct rpm, lubricant and tap grade still matter — we recommend a sample piece for setup.
Q3: Blind hole or through hole?
A: Both. Depth control on the touchscreen handles blind holes; through-hole mode runs continuous forward-reverse cycles.
Q4: How is torque controlled?
A: Electronic torque protection in the servo drive plus adjustable torque collet — when resistance exceeds the set point, the tap slips instead of breaking.
Q5: What is the working radius?
A: 1000mm from the column. Longer arm or magnetic base options are quoted separately.
Q6: What voltage?
A: Standard 220V/50Hz; 110V/60Hz or 415V configurable by destination.
Q7: CE and ISO?
A: CE/ISO configurable. Certificate scope confirmed per order and market.
Q8: What is the price and lead time?
A: Starting from US$1,000. Final quote depends on collets, arm length, base type, voltage and accessories.
Q9: How do I request a quote?
A: Send thread sizes, material, hole depth (through/blind), workpiece size, voltage and monthly volume. Wadjay returns configuration and price.
