The pneumatic lift version of the Lapmaster Model 20 is based on the open face machine. Pressure weights are attached through self aligning bearings to the rods of the pneumatic cylinders. The cylinders are mounted on a framework located over the lap plate on an upright column. The primary function of the pneumatic arrangement is to permit loading and unloading to be carried out without the need to lift pressure weights manually. However, they can be used to supply additional loading to the components within the conditioning ring should this be required. The machine is intended for use with free abrasive compounds. A dispensing system, for use with water and diamond compounds etc., can also be fitted. Operator safety is a primary concern in the design. Movement of each pressure weight up or down is controlled by a two hand anti tie down control box. This arrangement requires the use of both hands on two separate buttons to function, which reduces the risk of injury when lowering the weights. A further safety feature ensures that the pressure weights are locked in any position, so that in the event the air or electrical supplies fail, the weights will not fall. Flatness of the machines lap plate, and consequently of the component, is controlled by adjusting the position of the conditioning rings relative to the lap plate track. This popular bench mounted machine is also available in an open face version.
