Harrison alpha 400 centre lathe

Harrison alpha 400 centre lathe 1

The Alpha Plus range of electronic centre lathes from T.S. Harrison represents a significant leap forward in productivity engineering, building upon the exceptional performance of the renowned Alpha Ultimate Centre Lathe. Here are some key features and benefits of the new Alpha Plus:

1. **Automatic Cycles and Comprehensive Guarding**: The Alpha Plus range introduces automatic cycles and comprehensive guarding, meeting CE requirements. This allows for manual, sequential, or semi- or fully automatic cycle operation, enhancing versatility and productivity.

2. **Reduced Production Times**: Automatic cycles enable the Alpha Plus to significantly reduce production times for both one-offs and small to medium-sized batch runs.

3. **High Quality and Accuracy**: The machine's robust mechanical construction, precise ballscrew accuracy, and closed-loop positional feedback ensure highest quality and accurate repeatability.

4. **Full Length Threading and Thread Chasing**: The Alpha Plus facilitates full-length threading on automatic cycles, and it also offers flank angle approach capability and thread chasing.

5. **User-Friendly Design**: Designed to be simple to use and operate, the Alpha Plus allows operators to start producing parts immediately. Harrison's AlphaLink software further simplifies operations by allowing complicated parts to be simulated on screen before machining.

6. **Unique Machine**: The Alpha Plus stands out as the only centre lathe of its kind in the world, offering traditional lathe feel and performance with vastly improved output and profitability.

Certainly, here's the revised description without bold formatting:

The Alpha Plus offers the functionality of three machines in one, providing versatility and efficiency for various machining operations:

1. Manual Turning: Allows manual turning without any restrictions, providing flexibility for conventional lathe operations.

2. Turning with Electronic Stops: Enables turning with electronic stops, including radius, chamfer, groove, taper, and automatic screw-cutting. This feature enhances precision and consistency in machining operations.

3. Recording of Components via PC: Components to be machined can be recorded via your PC, with an automatic operating sequence. This streamlines the setup process and ensures accurate machining of multiple components.
