Universal Cylindrical Grinding Machines

W 11 CNC

  • Grinding length, max.: 650 / 1,500 mm | 25.5 / 59 in
  • Center height: 200 mm | 8 in
  • Grinding Ø external: 1 / 390 mm | 0 / 15.5 in

W 11 CNC External-Internal Face Cylindrical Grinding Machine

When a high-end CNC machine is too much and a conventional machine is too little, the solution is: EMAG WEISS W 11 CNC CYLINDRICAL GRINDING MACHINE.

W 11 CNC Cylindrical Grinding Machine - Perfect for One-Offs, Prototypes and Small Batch Production

The W 11 CNC cylindrical grinding machine is perfect for one-offs and prototype production. This cylindrical grinding machine is also used for small batch production with a few diameters, for match grinding and sample production in the field of training and maintenance. 

The W 11 CNC cylindrical grinding machine includes the following in its design:

  • Hydraulic-free
  • Axle drives with servomotor and ball screw
  • Technology to input grinding parameters via touch screen
  • Automatic parallel dressing with compensation
  • Automatic releasing

W 11 CNC - Manual CNC-Supported External-Internal Cylindrical Grinding Machine

The control system of the W 11 is a modern, fast, grinding-oriented control system with a Windows interface, as well as, a USB and network interface for easy program management. Programming is performed using a dialog interface or DIN ISO programming. All common grinding cycles are included. Options include a DXF converter, geometry editor and special grinding cycles. 

The CNC control can be easily used for automatic dressing, grinding of multiple diameters, saving of grinding sequences, contour dressing and taper grinding in rail operation.

Despite a CNC control, manual cylindrical grinding is still possible.

Workpiece Headstock, Tailstock and Grinding Headstock

The spindle socket (MK4/MK5/MK6) has a precision spindle bearing with a concentricity of less than 0.5 µm. The speed is infinitely variable from 1 - 650 rpm. Additional options include: 

  • Vertical center
  • Special clamping devices, central clamping

The tailstock (MK4) can be operated manually and pneumatically with a foot switch. The quill cone (MK4) allows for a loading weight between centers  of up to 250 kg (551 lbs). The quill stroke is 45 mm (2 in). Option: manual cylinder correction

The grinding headstock has a precision spindle bearing / angular contact ball bearing or hydrodynamic plain bearing. 

The following grinding wheel dimensions are possible:

  • Ø 400/500 mm (16/20 in), width 10 - 120 mm (0.4 – 5 in)
  • Drive power 9 - 11 kW

A B-axis (direct-driven torque axis) is available as an option for infinitely variable swivelling/positioning of the grinding headstock.  Additional options include:

  • Transformation of the center-of-rotation coordinates of the grinding wheel
  • SUG
  • CAP/crash control

Advantages W 11 CNC

  • Extremely versatile
  • Easy to set-up
  • User-friendly
  • Quick clamps on the assemblies for retooling
  • Very precise feed and dimensional accuracy within 0.001 mm
  • Easy operator accessibility
