MASS PRODUCTION GRINDING MACHINE

The PG is a machine for standardised parts in mass production.
Due to the tremendous stiffness of the machine structure, you can use bigger grinding wheels (up to Ø915 mm) to get higher efficiency.

A machine dedicated to making a single part with the following dimensions:

1000 mm
500 kg
80 m/s
CBN
Ø440 mm
Ø915 mm
PG
Highlights

Wheels up to Ø915 mm to grind in one set-up

  • Max. wheel dimensions, straight and angular, single wheel: Ø760 x 350 mm or Ø915 x 200 mm
  • Max. wheel dimensions, B axis, multiple wheels: Ø760 x 200 mm
PG
Highlights

Although it’s a single part machine, it’s easy to retool the PG

We adapt your machine to your new process, adjusting all the required mechanics and software.

PG
Highlights

One of the most ergonomic grinding machines

  • Large protective window for excellent visibility of the working area
  • The distance between the operator and the workpiece axis is perfect for part (un)loading
  • The design enables a fast grinding wheel change
Technology
When we talk about high production, every detail matters
Machine structure
  • Manufactured and machined on a unique and rigid piece
  • Made of stress-relieved pearlitic cast iron
X and Z axes
  • Hydrostatic V and flat slideways
  • The slide is driven by a ballscrew with direct coupling to a CNC controlled servomotor
  • A high resolution absolute linear scale controls the positioning
Workhead & tailstocks
  • Rigid castings, made in modular designs with selected materials for stable temperature performance
  • Compressed air lifting systems for comfortable set-ups, and easy repositioning of the tailstock along the table
Grinding spindle heads
  • Mounted on proven ultra precision bearings (hydrostatic optionally) with lifetime grease lubrication
  • Driven by built-in electro-spindles
Swivelling B axis

Automatic swivelling, driven through a torque motor, and controlled by high resolution rotary encoder.

It can position in any angle, with a mechanical locking and pneumatic unlocking system.

Customisation
