Machine specification

TC40B400L Horizontal CNC Lathe

Start with your part or operation. A model and drawing are optional for the first contact.

The TC40B400L is a horizontal CNC lathe for shaft, sleeve and disc-turning projects. Its documented maximum turning diameter for disc-type workpieces is 340 mm and maximum workpiece length with a chuck is 400 mm. Check these limits separately from the X/Z-axis travels of 220/430 mm. Material, workholding, tool access and automated loading require engineering confirmation.

What is this machine used for?

Discuss this configuration View specifications

Check the configuration against your part

For a shaft or sleeve, review chuck engagement, supported length and the full operation sequence. For a disc or flange-shaped component, review the documented 340 mm turning diameter together with swing diameter, jaw projection and tool access. These are evaluation routes, not an approval of the complete setup.

Configuration and acceptance

The listed values describe documented specifications; they do not establish the complete standard supply. Confirm the CNC, tooling, workholding, spindle duty and acceptance conditions in the quotation. Optional items require explicit selection.

Axis travel is not guaranteed workpiece clearance. Machine positioning and repeatability figures do not guarantee finished-part tolerances. Review the drawing, material, fixture and inspection method together.

Before choosing this machine

How should I compare a shaft and a disc-shaped part?

For a shaft, check the chuck engagement, supported length and operation sequence. For a disc-shaped part, check swing diameter, turning diameter and tool approach. Ask for a drawing review before selecting the setup.

Does this page confirm a material or automated loading system?

No material or loading-system compatibility is confirmed here. Tell us the material, part form and loading requirement so the team can review the proposed configuration.

What should I send with an inquiry?

Send the drawing or part dimensions, material and operations required. Add the quantity, critical tolerances and loading preference if known. Include the model code so we can review the selected configuration.

Do the specifications define the complete standard supply?

No. A listed specification does not establish the complete standard supply. Confirm the selected CNC, spindle duty, toolholding, workholding and any optional items in the final quotation.

Confirm the TC40B400L configuration for your part

Use the published specifications to shortlist this model, then confirm the configuration with the contact listed on this site. Axis travel, workpiece capacity and table load describe different limits; they do not establish finished-part tolerance, material suitability or cycle time. A drawing is optional for the first contact. Machine prices and formal quotations are provided directly by the contact, not by this website.

  1. Check the published data. Read the available specification labels, units and configuration notes. Ask the contact for missing technical data for this exact model. An omitted value is not zero.
  2. Confirm the supplied configuration. Ask the contact for configuration-specific technical information. Confirm standard and optional equipment, tooling, workholding and acceptance requirements; do not assume an unlisted feature is included.
  3. Discuss your requirement. Start with the dimensions and operations you know. Agree a suitable channel for confidential drawings directly with the contact.

Does submitting an inquiry confirm the machine or a quotation?

No. An inquiry starts a discussion. The contact must confirm the proposed configuration and commercial terms with you; submitting a form is not machine acceptance or a formal quotation.
