Frequently Asked Questions
Common questions and answers about this model.
What materials can the Eziturn ST30 Series (ST-770H) machine?
The Eziturn ST30 Series (ST-770H) is suited to turning common metal materials such as aluminum, copper, carbon steel and stainless steel. Actual workable materials and ranges depend on the model specifications and workpiece conditions.
What control system does the Eziturn ST30 Series (ST-770H) use?
It runs LIHAITEC's in-house Eziturn / Ezimill Intuitive Touch Smart control system: the operator taps the machining point on the drawing, and the system automatically detects the contour and generates the toolpath — no G/M code — mirroring how shop-floor machinists think about machining. The control system is developed in-house by LIHAITEC, integrates automation such as a robotic arm and automatic feeding, and is built to order; the same system applies across lathes and mills (Utility Model M670627, Automated Machine Tool Controller, not limited to one machine type).
How can I get a quote and lead time for the Eziturn ST30 Series (ST-770H)?
The Eziturn ST30 Series (ST-770H) is offered on a quotation basis. Add it to your inquiry list or contact us with your requirements, and we will respond with pricing and lead time based on configuration and stock availability.
What pre-sales and after-sales services come with the Eziturn ST30 Series (ST-770H)?
LIHAITEC provides full pre-sales and after-sales support, including on-site installation, operator training and trial runs, and warranty service (warranty period as agreed in the contract).
Is the Eziturn ST30 Series (ST-770H) hard to learn? Do I need programming skills?
No. The Eziturn ST30 Series (ST-770H) uses blueprint-style intuitive operation — tap a point on the drawing and the system automatically detects and generates the toolpath. A machine is for cutting parts, not for learning a programming language, so operators get up to speed quickly.
Can the Eziturn ST30 Series (ST-770H) be automated for high-volume production?
Yes. The Eziturn ST30 Series (ST-770H) can be fitted with a robotic arm and automatic feeding / load-unload. Combined with the saved machining graphics, conditions and origin, it runs unmanned around the clock — 24 hours non-stop — for lights-out mass production with no programming. The Eziturn ST30 Series (ST-770H) is built to order.
How do I choose between the Eziturn ST30 Series (ST-770H) and other models in the same series?
Models differ in machining size and configuration. We suggest reviewing the spec table on this page and comparing other models in the same series; if you're unsure, contact us and we'll help you select based on your machining needs.
