What is this machine used for?
The TYB900-2 is a double-head vertical cnc lathe with a listed maximum swing diameter of Φ900 mm, maximum turning diameter of Φ800 mm, and maximum turning height of 750 mm. Its documented spindle speed is 0~1500 rpm. Compare the turning envelope, workholding, tool reach and operation sequence with your drawing, then confirm the selected axis, spindle and tooling configuration in the quotation.
Choose the configuration around your part
Define the reference face, loading orientation and complete machining sequence. Check the turning diameter and height against the selected chuck and jaws, then review any milling, offset or second-head operations separately. Submit the fixture layout and acceptance requirements with the part drawing.
Questions before ordering TYB900-2
Which workpiece dimensions should I check first?
The listed swing diameter is Φ900 mm, maximum turning diameter Φ800 mm, and maximum turning height 750 mm. Confirm chuck opening, jaw height, part support, tool approach and any off-centre features with the complete workholding layout.
How should I interpret the spindle and tooling data?
The documented spindle speed is 0~1500 rpm. Compare the main turning spindle separately from any milling spindle or driven-tool system. Confirm the actual head arrangement, duty rating, tool interfaces and simultaneous-operation requirements before selecting equipment.
What is included, and what needs configuration confirmation?
Rows marked optional describe available configurations. Other listed values do not by themselves establish the complete standard supply. Confirm the control, workholding, spindle duty, tooling, chip handling and acceptance scope in the quotation.
Can the listed accuracy establish my finished-part result?
Listed positioning, repeatability and surface-finish figures are machine specifications under their stated conditions. Finished-part results also depend on material, tool, workholding, thermal state and measurement method. Provide the drawing and required inspection standard for process and acceptance review.
What should I send for an actionable quotation?
Send a dimensioned part drawing, material, critical tolerances, batch size, current process, proposed workholding, required controls and delivery destination. Identify any installation constraints and selected configuration so the team can review the same production requirement with you.
