VT 2-4 and VT 4-4 Shaft Automation: Turret Grippers and Part Limits

The VT 2-4 example lists maximum part length 400 mm and diameter 100 mm.

Technical application analysis. Shaft components; VT 2-4 and VT 4-4 vertical shaft machines; turret-mounted workpiece grippers.

Reference configuration and timing

The VT 2-4 example lists maximum part length 400 mm and diameter 100 mm.
The VT 4-4 example lists 630 mm length and 200 mm diameter. Reported loading/unloading is 6–8 s, rather than the full machining cycle.

Engineering evaluation

The shaft is held vertically between spindle and tailstock while turret functions support the process. Grippers use turret positions and occupy access space, so not every available station can automatically be counted as a cutting-tool position.

Longer shafts change the transfer envelope, support requirements and vibration behavior. Check tailstock travel, center of gravity and permitted gripping surfaces rather than enlarging the jaws alone.

Selection conditions and evidence limits

C015 and C031 are combined while preserving their different machine limits. These product descriptions do not establish a specific material, universal cycle or New Partner installation.

Application questions

Can the VT 4-4 envelope be quoted for the VT 2-4?

No. The cited dimensions belong to different models and must remain separate.

What is the tradeoff with turret-based loading?

Handling can be integrated, but its grippers and paths must coexist with cutting tools and the shaft support arrangement.
