LANG Self-Centering Vise Kit for Pocket NC

Professional-grade industrial workholding for the Pocket NC. Pairs LANG Technik's ultra-compact Micro 46 self-centering vise with a custom Pocket NC mounting fixture — industrial precision in a desktop 5-axis setup.

Key benefits

• Ultra-compact design for excellent 5-sided access and tool clearance
• Self-centering precision — fast, repeatable setups with 0.02 mm centering accuracy
• Serrated jaws with precision flats for strong clamping on both raw stock and pre-machined parts
• Enhanced process reliability — low clamping pressure reduces distortion and vibration
• Direct integration via a custom fixture that bolts directly to the Pocket NC table
• 6 kN clamping force for maximum part stiffness during machining

Specifications

What's in the box

• LANG Makro·Grip Micro 46 self-centering vise
• Pocket NC custom mounting fixture
• Mounting hardware (4× M5 cap screws)
• LANG hex key for jaw operation
• Setup + first-use guide

Setup on the Pocket NC

1. Remove the standard vise or fixture from the trunnion table
2. Bolt the LANG custom fixture to the table using the 4× M5 cap screws
3. Snap the Micro 46 vise onto the fixture — it self-aligns to the 0.02 mm tolerance
4. Mount your stock between the serrated jaws
5. Tighten to spec using the supplied LANG hex key — no calibration drift
6. Re-set your workpiece zero — the fixture offset is consistent to ±0.01 mm visit-to-visit

LANG vs Sherline 4-jaw vs standard Pocket NC vise

Why a self-centering vise matters for 5-axis

5-axis simultaneous machining magnifies any workpiece-mounting error. A 0.05 mm offset between visits produces visible witness lines on the part when the spindle rotates through B/A. The Micro 46's 0.02 mm self-centering tolerance is the precision floor needed for repeatable parts across multiple setups.

FAQ

Will it fit the V2-50 too?

Yes — same trunnion mounting pattern across V2-10 and V2-50 (CHB and CHK). The fixture is universal.

What's the max stock width?

The Micro 46 has a 46 mm jaw width and grips stock from ~10 mm to ~50 mm depending on jaw orientation. Beyond that, soft-jaw extensions are available — ask sales@cyclecnc.com.

Is it production-ready or lights-out capable?

Yes. The 6 kN clamping force + 0.02 mm self-centering tolerance is what professional shops use for production-grade Pocket NC work — including unattended lights-out runs on hardened alloys.

Lead time?

Köln stock when available. LANG factory restock is 2–3 weeks. Confirm current stock with sales@cyclecnc.com before ordering for time-sensitive projects.
