Numturn TC 420 CNC

SKU : 180143

Our Numturn series is the perfect solution for small to medium sized workpieces to be machined on a powerful CNC lathe. The robust box-way design provides high rigidity and a large workspace. The SIEMENS CNC is carefully matched to the respective application. Two electronic hand-wheels ensure quick set-up and allow use of the machine like a manual lathe. The Numturn series is the best choice for maintenance/service departments or single parts production.

Machine Set-up

  • The heavily ribbed machine frame features wide hardened v-block guideways for machining long workpieces
  • A powerful 7.5 kW motor with infinitely variable speed drives the main spindle
  • Premium preloaded ball screws and servo drives ensure consistent dynamic feed and precise positioning on both axes
  • The tailstock with hydraulic quill impressively easy to handle and features high clamping holding force

Tool Changer

  • An automatic 8-station tool turret is part of the standard package and ensures maximum flexibility and productivity
  • A powerful coolant pump feeds the tool mount nozzles through the turret to ensure precise and effective cooling

Operating

  • The NUMTURN series provides state-of-the-art ergonomics for quick and easy operation
  • The button and hand-wheel functions are displayed intuitively on the movable control panel
  • Both electronic hand-wheels allow precise control of X and Z axes, simplifying machine set-up and speeding up manual machining

Control

  • The SINUMERIK 808D ADVANCED is a perfect match for the Numturn series’ application profile
  • Leading CNC technology plus a revolutionary operating concept make the SINUMERIK 808D ADVANCED the perfect entry-level machine for newcomers in the world of CNC machining
  • The Manuel Machine + (MM+) Software package is included
  • It allows machining of workpieces without having to create a complete parts program

Equipment

  • The hydraulic chuck with adjustable clamping force has a through-hole for holding longer workpieces through the spindle
  • The totally enclosed machine features a wide-opening sliding door for easy access
  • An automatic central lubrication system reliably supplies all lubrication points and simplifies maintenance
  • Electronics are protected within a fully enclosed control cabinet, and a powerful heat exchanger manages the temperature
  • Hand guns for coolant and compressed air are mounted easily accessible at the machine

SINUMERIK 808D ADVANCE is perfectly tailored to the requirements of modern standard machines.

Communication between the CNC and drive via high-speed bus ensures efficient position control, which guarantees high precision and optimum cutting performance.

This guarantees an outstanding price/performance ratio.

In combination with a new generation of spindle and axis drives, SINUMERIK 808D ADVANCE with 8.4’ LCD represents the latest ready-to-use digital CNC solutions for modern standard machines.

Advantages - Higher precision thanks to digital solutions:

The higher overload capacity supports shorter acceleration and deceleration of the machine tool.

Thanks to a stable cutting speed, a better surface quality of the workpiece can be achieved.

Greater ease of use:

Fast Ethernet makes it easier to commission and diagnose the machine tool and handle the NC programme.

Manual Machine + (MM+):

With the Manual Machine + (MM+) software package, SIEMENS offers a graphically supported user interface for the SINUMERIK 808D CNC control, which greatly simplifies the production of individual parts and small batches.

The Siemens 808 supports the user right from the programming stage by graphically displaying machining cycles and contours.

In MM+ mode, the control enables the machining of workpieces without having to create a complete part programme.

The following machining operations are supported:

  • Axis-parallel machining
  • Taper turning
  • Radius turning
  • Drilling
  • Tapping
  • Grooving/cutting off
  • Thread cutting
  • Contour machining

Clear and easy-to-understand input masks are available for defining the individual functions.

Note: The machine manufacturer can specify the mode in which the control is started up (MM+ or standard).

The advantages at a glance:

  • Intuitive operation for conventionally trained lathe operators
  • High time savings for simple machining operations
  • Create contours directly on the machine without in-depth programming knowledge
  • Short familiarisation period
