Overview
HY320 Product Introduction
The HY320 is a CNC 4th axis rotary table for machining centers, built on a roller cam drive system. As the largest model in the range it is intended for operations that require more table area and greater clearance from the spindle.
Typical use is indexed and continuous rotary work on shafts, flanges, fittings and similar rotationally symmetric parts, with the workpiece supported either by a chuck, a fixture plate or a combination with a suitable tailstock.
Technical data for the HY320 — including table diameter, center height, workpiece envelope, weight capacity, accuracy figures, motor and encoder configuration — is published on this page only after verification by our engineering team. Fields that depend on the selected motor, encoder and workholding option are marked On request; send us the machine and control details and we will return the matching configuration.
If you send us your machine brand, machine model and controller, we can confirm the suitable HY320 configuration before quotation.

HY320 Features
Design features of the HY320 platform. Detailed figures, options and verification status are listed in the specification and configuration sections.
Roller cam drive system
Rotary motion is transmitted through rolling elements in continuous engagement with the cam profile.
Largest table in the range
Intended for larger workpieces and operations that need maximum clearance from the spindle.
Motor & encoder configuration
Configuration is matched to your machine and controller. Supplied configuration to be confirmed.
Workholding interface
Chuck and fixture-plate interface options are confirmed per model — see configuration options.
Tailstock support
Can be combined with a matched tailstock for longer shaft-type workpieces. Matching details to be confirmed.
Documentation per unit
Dimension drawings, installation information and test records are provided as available per unit.
Drive Technology
Roller Cam Technology in the HY320
The HY320 uses the roller cam drive platform shared across the 4th axis range, sized for the largest model. Backlash and accuracy values are published only from verified test data.
Mechanical structure
A cam profile drives rolling elements to produce rotary motion in a compact drive package.
Rigidity
The drive structure is designed to support machining loads acting on the rotary axis.
Positioning performance
Suited to indexed positioning for multi-side machining operations.
Durability
Rolling contact in the drive train is designed to support durable operation in production environments.
Applications
Applications for the HY320
The HY320 is positioned for larger rotary machining applications, including large shaft, disc and complex multi-side parts. Final suitability depends on your workpiece data, fixturing and machine.
