Overview

TOS Varnsdorf is a Czech manufacturer of CNC horizontal boring and milling machines with over 100 years of production history in Varnsdorf, Czech Republic. The W200H is a table-type horizontal boring machine with a 200 mm diameter boring spindle, designed for heavy precision machining of large structural components, industrial housings, and capital equipment frames. The machine processes workpieces up to 5,000 kg on a CNC-controlled rotary table with full 360-degree indexing and 0.001-degree increment positioning. The W200H's spindle extends to 800 mm for deep boring operations inside large housing structures without repositioning the workpiece. TOS Varnsdorf machines combine central European precision manufacturing with competitive pricing against Western European alternatives, making them popular in energy sector fabricators, mining equipment manufacturers, and defense prime contractors needing large-format precision boring at lower capital cost. The machine uses a Heidenhain iTNC 640 or Siemens 840D sl control for full contouring.

Frequently Asked Questions

01 What is the maximum bore diameter the W200H can achieve?

The W200H spindle diameter is 200 mm. Using boring bars and facing heads, it can machine bore diameters from a few millimeters to over 1500 mm in diameter depending on tooling extension.

02 Can the W200H perform milling as well as boring?

Yes. Like all horizontal boring mills, the W200H performs milling, drilling, threading, and contouring in addition to boring. It is a full horizontal machining center with the spindle optimized for large-diameter boring operations.

03 What is the difference between table-type and floor-type boring machines?

Table-type (like the W200H) mounts the workpiece on a rotating table, providing rotary indexing capability. Floor-type boring mills use a floor-mounted workpiece with the boring head traversing over it — suitable for extremely large workpieces that cannot be mounted on a table.
