Product Description - PPSM

The principle

The high precision profile grinding machine moves a column in x-direction and works with a programmable servomotor-driven C-axis with a swivel area of –30° to +30° for helical gearings. The basic machine includes an range of equipment features that allows to use the machine in a very high level of machine availability for the precise production. Encapsulation, a position measuring system for all axes (apart from rotary axes), as well as a conditioned cabinet are equally important and therefore part of the standard version as well as chip conveyors, a filter system for the cooling agent and shock-absorbing elements.

The basic machine: stable and dynamic

The machine bed of the travelling column machine is made of a ripped welded construction. The generously dimensioned guides consist of the linear axes X, Y, Z, W and U made of high-precision profile guides which are centrally lubricated. Heavy steel covers protect the guides of the linear X- and Y-axes.

Control: Innovative system platform

A 840D sl Siemens control with Sinamics-drives in a Rittal conditioning cabinet is used. The user-friendly User Interface guarantees easy and comfortable machine operations.

Benefits

Highly rigid construction

The rigid construction guarantees a long lifespan combined with highest precision.

Highest dynamic

State-of-the-art linear drive technology ensures increased productivity.

Non-stop production

  • With the option “partition” the insertion can take place during primary processing time without any downtime
  • Standard and fully automatic position determination
  • Travelling column design for loading and unloading by hand, by crane or by handling system

Easy-to-use

With the sophisticated operating concept ergonomic handling and short training units are possible.

  • Equipped for teleservice
  • Special user interface for different gearing and workpieces types

Precise incremental measuring system

working area

With the option partition you can load and unload the machine without downtime. By 4m working length the machine can be equipped with a fully automatic partition.

Cooling unit

Cooling unit with integrated deep-bed filter

Grinding head with balancing system

Fully automatic balancing system which recognizes and removes unbalances at a very early stage. This guarantees a high quality of the workpiece surfaces and a lang tool life of the spindle.
