4-Inch Rotary Table for Milling Machines with 3-Jaw Chuck

Overview

A φ4″ / 100 mm rotary table designed for precision milling and machining on small to medium milling machines. Engineered for precise positioning, rotation, indexing, and clamping of wood and metal workpieces, it supports curved surface machining, elongated hole processing, and precision drilling. Widely used in automotive, mold-making, and general machinery applications.

Features

• 3-jaw chuck with serrated jaws for secure grip on small workpieces
• Handwheel operation with crystal-clear scales on both wheel and table for precise measurements
• Handwheel scale marked to 100; table marked with 360 degrees
• Worm gear ratio of 1:36 for fine control—one handwheel rotation equals 10-degree table turn
• Supports both horizontal and vertical installation
• Positioning slots on table base for secure attachment to milling machines
