NOVAMATIC 4G WHEELHEAD UNIT

This equipment consists of two cross-mounted slides that provide maximum rigidity, known as “the cube“, with each slide moving on four preloaded and lubricated V roller guideways.

Precise control of X and Z slide movements is enabled through linear measuring systems that offer sub-micron resolution. The wheelhead unit is fully isolated from the working area.

WORKHEAD UNIT

The workhead unit is mounted on a swiveling plate that can be adjusted manually for convenient setup and changeover.

It can feature a roll-shoe centering fixture with an integrated load/unload system, a mag-drive shoe-centerless device with an integrated automatic loader that enables load/unload times below 1.5 seconds, or a diaphragm chuck type clamping fixture with enveloping jaws that allows direct mounting of a diamond ring on the workhead for wheel dressing.

Diaphragm chuck type clamping fixture with enveloping jaws or collets.

DRESSING UNITS

SINGLE-POINT DRESSER
For single-point dressing, this equipment offers holders for one, two, or three diamonds, depending on the desired wheel profile.

DIAMOND ROLL DRESSER
The diamond roll dresser operates hydraulically to move up and down. Dressing occurs through a plunge system with a profiled roll, or through interpolation of machine axes with a forming roll.

DOUBLE-FULCRUM ROTARY DRESSER
To achieve wheel radius profiles with form errors less than 1µ, this equipment can support a fixed holder for up to three single-point diamonds or an electric spindle with diamond disk. The dresser holder rotates electrically, driven by an AC motor through a gear reducer and encoder (E axis).

TURBINE
The electric spindle is taylored to dressing CBN wheels using a diamond cup wheel.

These are all these reasons, NOVAMATIC 4G can be considered the perfect solution on the market for the choice of large internal grinding machines.
