CHP eco: for guaranteed success

CHP sharpening machines set world-wide standards in technology. Because of their extra stability and guaranteed maximum precision. And because of their great versatility, easy operation and short grinding times. The CHP eco sets new standards in terms of price-performance ratio.

The sharpening processes of the CHP eco are controlled by two axes

Two CNC axes control the bevel grinding action and grinding wheel infeed. This allows any tooth geometry to be ground at the face or top in a single revolution - with different teeth in cluster arrangements and with different chamfer and bevel angles. And for saw blades used to cut wood, plastic, steel and non-ferrous materials.

A wide variety of applications

The CHP eco is an all-rounder which can be used for all kinds of sharpening tasks, and may well save you investing in costly special machines - a further contribution to increased economic efficiency in the sharpening shop.

The control desk is a convenient centre for programming and retrieving all the main functions. The LCD display with clear-text prompting keeps you supplied with all kinds of information such as the operating status or the tool life of the grinding wheels. A diagnostic program provides guidance on how to deal speedily with possible faults.

All tooth shapes machined with maximum precision

The examples show some of the tooth shapes which can be machined in a single revolution on the CHP eco. Even new and future tooth geometries can be machined thanks to the individual selection of all bevel-grinding angles. Programs for grinding newly soldered carbide teeth and skipping individual missing teeth are also available as standard.

Re-sharpening of metal-cutting saw blades

Even the often complex tooth geometries of metal-cutting saw blades can be ground at the top or face in a single revolution with CHP eco.

Advantages of the CHP eco:

Short grinding times, reduced ancillary times, excellent grinding results.
Easy to operate (all main functions set and activated at control desk)
Comprehensive software integrated.
Any tooth can be ground at the face or top in a single revolution.
Easy loading and unloading of machine.
Universal application, including grinding of cutting tools and different tooth pitches plus hollow face grinding or relief-grinding of the blade body.

CHP eco

The CHP eco is also available with a splash guard instead of full enclosure for some markets. The technical parameters are the same as for the fully enclosed version.
