Machine specification

TZ521 Swiss-Type CNC Lathe

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

The TZ521 is a Swiss-type CNC lathe with different limits for guide-bush and guide-bush-free operation. The listed machining diameters are 32 mm with a guide bush and 52 mm without one; the single-setup length with a guide bush is 220 mm. Review the two modes separately, including bar support, main/sub-spindle tooling and the required operations. Material and loading equipment require engineering confirmation.

What is this machine used for?

Discuss this configuration View specifications

Check the configuration against your part

Select guide-bush or guide-bush-free operation first. Do not combine the 52 mm guide-bush-free diameter with the 220 mm guide-bush length into one capacity. The guide-bush-free length is listed as three times bar diameter, not a calculated fixed length. Review bar support, main/sub-spindle tools, material and any requested loading equipment for the actual part.

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

Which limits should I check for my workpiece?

Select guide-bush or guide-bush-free operation first. Do not combine the 52 mm guide-bush-free diameter with the 220 mm guide-bush length into one capacity. The guide-bush-free length is listed as three times bar diameter, not a calculated fixed length. Review bar support, main/sub-spindle tools, material and any requested loading equipment for the actual part.

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. Use the inquiry link on this page to include the model with your request.

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.

Discuss this configuration

Confirm the TZ521 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.
