HOMMEL-ETAMIC AG100Air spindles with open air jets
HOMMEL-ETAMIC AG100 air spindles with open air jets are used to measure through-bores or ultra-precision blind-hole bores.
The diameter is established using two diametrically opposed, non-contact air jets, offset against the outer guide diameter of the air spindle. Measurements can take place either statically or dynamically.
The spindle is rotated in the workpiece to determine out-of-roundness and moved to determine conicity. On request, the air spindle can be fitted with three jets for measurement at three separate points (3×120°).
Our standard air tooling sizes range from 3 mm to 150 mm in diameter, with measuring ranges of 0.010 mm to 0.160 mm respectively.
There are four different standard types of air jets utilized on AG100 spindles. The type of jets used depends on the diameter, the surface structure of the workpiece to be measured, and the required measuring range.
The position of the air jets depends on the type of spindle being used and the nominal diameter to be measured. There are two types of tooling: ‘S’ (standard, for through bores) and ‘TP’ (jets located near the spindle end for blind-hole bores).
The air tooling can be connected to all Hommel-Etamic measuring instrumentation. In the case of portamic, C61 or pneutamic displays, the AG100 air spindles are directly connected to each device. Alternatively, they can be used indirectly via an electro-pneumatic converter (ARC99, TPE99 or TPE70/3). In this case, the measurement results can be displayed on an ESZ800, CMZ200, CMZ250 or ESZ400 measuring computer.
Hommel-Etamic air spindles are extremely reliable and robust. They can be used can be used hard mounted inline or on a bench, as well as on semi-portable handles for operational flexibility. AG100 air tooling is ideal for manual easurement
of bores in production lines, for automatic or semiautomatic measuring stations, and for the quality lab (subgroups or 100% monitoring).
Thanks to the pneumatic principle (high pressure), any special maintenance processes are eliminated - a simple cleaning is all the tooling requires.
To ensure the selection of the best possible air spindle for your
application, the following information is required:
• Drawing of the workpiece to be measured
• Diameter, tolerance, and surface structure of the bore to
• Type of bore (through-bore or blind-hole bore)
• Type of material required for the air spindle: hardened steel
(100,000 workpieces to be measured) or surface-treated steel
(1,000,000 workpieces to be measured)
• Required measuring range
• Pneumatic combination, if the air spindle is to be connected
to an existing device
