BENTDIUM BTM-ARK-50 Precision CNC Milling Vise
Large-Format High-Rigidity Workholding Vise for Heavy-Duty Machining Centers
Product Overview
The BENTDIUM BTM-ARK-50 Precision CNC Milling Vise is engineered for the most demanding heavy-duty milling and machining center operations, combining ultra-long clamping travel, monolithic rigidity, and micron-level accuracy to handle standard and oversized workpieces alike. Built to eliminate deflection under aggressive cutting loads, this vise delivers consistent, repeatable results for precision milling, drilling, and multi-axis machining tasks.
Key Features & Benefits
✅ Ultra-Large Jaw Opening for Oversized Workpieces
Designed with an extended lead screw and reinforced body, this vise offers an impressive maximum jaw opening of up to 400mm (on the largest model), accommodating long, large-format, or oversize workpieces that standard vises cannot handle. The precision-machined lead screw ensures smooth, uniform clamping force across the full travel range, eliminating slippage or misalignment during heavy cuts.
✅ High-Rigidity Precision-Ground Main Body
The thickened monolithic main body is precision ground on every surface to deliver exceptional stability and zero deflection under load. Strict tolerances ensure consistent performance across every setup:
- Flatness, parallelism, and squareness: ≤0.002mm
- Parallelism tolerance: ≤0.005mm / 100mm
- Perpendicularity tolerance: ≤0.008mm / 100mm
- Body height tolerance: ±0.005mm
- Squareness (90°): ≤0.01mm / 100mm
This precision ensures cuts stay true to design, even in high-stress machining operations.
✅ Premium 20CrMnTi Alloy Steel Construction
Manufactured from high-grade 20CrMnTi alloy steel, this vise undergoes a carburizing and quenching process to achieve a dual-property structure:
- Surface hardness: HRC 55° ~ 60° for exceptional wear resistance against repeated clamping and cutting forces
- Ductile, shock-absorbent core to prevent cracking and deformation under heavy loads
This combination ensures long-term durability in high-volume production environments, withstanding years of daily use without wear or performance degradation.
✅ Modular Replaceable Jaw System
The interchangeable jaw design expands the vise’s functionality to suit nearly any machining requirement. Swap in different jaw types (serrated jaws for high-grip roughing, soft jaws for delicate finished parts, or custom-profiled jaws for irregular shapes) to adapt to new workpieces without investing in additional tooling. This flexibility reduces setup time and lowers overall tooling costs.
