To permit installation of various sizes of deburring chambers, matched to particular sizes, or combination of sizes of workpieces, so that only the minimum size chamber for the particular quantity or size of workpiece need be used, the chambers are provided in sets with adapters so that a single machine frame can be utilized, the adapters and chambers being fitted within the machine frame so that the lower edge (13a, 13'a) of any one of the chambers is within the closing or sealing stroke of a closing plate (14) carrying the workpieces. A coding system, for example coding bolts (16) is secured to each one of the chambers, to be scanned by a reading head (17) and transmitting information relative to the appropriate fill quantity and pressure of gases for the particular chamber then being installed in the machine.
