Milling machine vise ACK series

5-axis machine toolfor machine toolssingle

Overview
Designed for high-precision second-operation finishing on 4- and 5-axis machining centers. Compact footprint and single-direction clamping reduce setup time and support consistent multi-face machining workflows.

Features

• Single-direction clamping with repeatable positioning precision of ±0.01 mm.
• Bottom mounting holes accept both 52 mm and 96 mm pull-stud patterns for rapid zero-point integration.
• Hardened slideways (HRC 50) and SCM440 alloy jaws (HRC 48–50) for wear resistance and stable clamping.
• Compatible with precision 4- and 5-axis CNC machines, indexing tables, and vertical or horizontal machining centers.
• Recommended for multi-face, high-precision parts in aerospace, medical and automotive industries.

Standard Accessories

• 2 pcs mounting screws
• 4 pcs clamps
• 1 pc wrench

Optional Accessories

• Zero-point quick-change devices
• Pull studs (M-52x52PS, M-96x96PS)
