Grindline
Online measurement of short centreless ground metal and ceramic components
The Grindline.X system is a cutting edge, very accurate and flexible laser measurement system.
It has been developed by online laser measurement experts, AEROEL for the online control and measurement of ground parts produced by through-feed or centreless grinders, including shape recognition and individual measurement of multiple diameters or tapers (Grindline+.X40 or Grindline+.X80 systems).
Installed at the grinder output, it measures through-feed without stopping or slowing the parts. Measurement of complex parts such as motor shafts, hydraulic components, shock absorber rods or pins can be achieved online and tolerance alarms and outputs can be used for part sorting. Grindline can also perform automated regulation to compensate wear of the grinding wheel.
Easy, accurate laser measurement for diameter of ground parts
The Grindline system includes the new CE-200 operator interface panel, with colour-coded tolerance display and easy programming and product library selection.
- Diameter 0.06 to 78 mm, depending on model
- Resolution from 0.01 µm
- Repeatability from 0.1 µm (3σ, 1s)
- Automated in-process regulation of grinder
- Detailed statistical reports in real-time or logged on a computer
- 100% quality control
- Bar sorting for reject or rework
- Efficient glass logic for transparent tubes or coated cables
- Accessories available including air-purge windows for gauges, air-blowing rings to clean emulsion from bars, etc.

The basic package includes the following functions:
- It measures up to 10 different diameters on the same part
- Display of measured values and their shifts from the nominal set points
- Diagram of the measuring deviations
- Automatic recognition of the selected ground lengths and filtering of all shape irregularities
- Parts being checked can be transported by conveyor or gantry loader
- On one selected section it is possible to check taper, by reading the diameter in two programmable positions: the difference between these readings is compared with the preset taper value
- Nominal diameter and tolerance programming
- Out-of-tolerance alarms (Go/NoGo) and delayed signals for part sorting (Reject/Rework)
- Signal for “unidentified piece” to discard abnormal parts, if any
- Library of parameters for 1000 different products, directly retrievable by the operator
- Possibility of entering a password to restrict the programming functions to authorized personnel
- Ethernet / Rs232 interface for remote programming or data retrieval
- Multi-lingual menus (Italian, English, French and German)
- Selectable measuring unit (mm or inches) and resolution
- Pre-programmed factory set-up to facilitate installation and start-up of the system
The additional Process Regulation module (Option 1) features the following functions:
- The automatic diameter regulation, achieved by adjusting the distance between the grinding wheels, is based upon the diameter shift read on one section only, as selected by the operator
- PI (Proportional-Integral) mode, using INC (+) or DEC (-) pulse trains, whose number is proportional to the amount of the required correction
- Regulation is started after having positively checked a real trend to drift from the nominal set point
- Control parameters can be programmed and stored in the product library
- Automatic backlash recovery, by adding extra pulses each time the correction is reversed
- To avoid over-regulation, the control routine skips the already machined parts included between the gauge and the wheels
- Additional input to hold regulation during diamond dressing of the grinding wheel
The additional Statistics module (Option 2) offers the following functions:
- Processing and printing of a statistical report for each selected batch or order
- Computing and listing of max, min, avg, Cp and Cpk values of each measured parameter (all the diameters and taper)
- Identification of the order, of nominal value, of tolerance range and counting of parts included in the selected batch
- Statistics can include all the parts of the batch (good and rejected), or it can be restricted to the good parts only
- All reports show the date and time
- Motor shafts
- Pistons
- Hydraulic components
- Plugs
- Gudgeon pins
- Additional software for grinder feed-back
- Additional software for statistical reporting
- Compressed air windows with filters and adjusting valve
