AR340
DKM · AR340-V1Compact model for small thread sizes and tight center distances. M3–M4 threads, 400 W servo, fast tap change.
Servo-driven, air-assisted Direct Drive unit. Operates independently of the press stroke and controls every thread pitch — M3–M10 threads, synchronized up to 32 SPM.

Designed and produced at our facility in Eskişehir, our in-die tapping units eliminate the secondary tapping operation and reduce production to a single step. We build long-term partnerships with strong technical support.
The part is finished in one press operation — no separate tapping machine, extra labor or part handling.
Tapping runs independently of the press stroke; speed, torque and depth are set precisely from the panel.
Chipless roll-forming produces smooth, high-strength threads and extends tool life.
Three bodies, one philosophy: compact build, Direct Drive and precise tapping that won't damage the part. Runs in automatic and manual modes.
Compact model for small thread sizes and tight center distances. M3–M4 threads, 400 W servo, fast tap change.
A balanced model for medium thread sizes. M5–M6 threads, 4.65–5.55 mm pilot drill, 400 W servo; a controlled 1460 rpm tap speed for torque on larger threads.
Powerful model for wide thread range and high-torque applications. M8–M10 threads, 750 W servo, automatic tap retraction.
M3–M10 tapping operations on high-volume sheet and metal parts.

In-die tapping for critical parts like engine blocks, transmission housings and brake calipers. High precision in one step, lower cost.

Thread forming on washing machine, dishwasher and refrigerator bodies. Vibration-free, clean, repeatable quality on aluminum and steel.

Tapping for critical-tolerance parts. Certified quality on titanium, stainless steel and high-strength alloys.
Technical guides on in-die tapping, roll-form taps and model selection.

We explain step by step how in-die tapping technology — which eliminates the secondary tapping operation — works, what advantages it offers and how it differs from classic methods.
