The AT940DDS twin drum finishing sander is the heavyweight of the range and is intended for the busy professional workshop where usage is more frequent and more arduous. N.B. These sanders are used for the final finishing process, they are not intended to be used as a thicknesser or with coarse abrasive for significant stock removal. In all instances, they are intended to be used with planed and thicknessed material.
The construction of the machine is predominantly of heavy gauge steel sheet, the 150mm diameter rollers are precision machined from aluminium castings and the power is supplied by two motors, 5.5kW(415V, 3ph) for the sanding drum drive and a 190W for the conveyor belt drive.
In use, the two drums are loaded with different grades of abrasive, coarse fitted to the front drum and fine on the rear and there is a choice of abrasive available to suit the type of timber being used and the finish required. The abrasive comes in 100 or 75mm wide strips and is wound spirally around the drums and securely held by wedge clamps. There is a very accurate setting system for the rear roller to allow easy adjustment to accommodate different grades of abrasive. The timber is held in contact with the conveyor belt by three pressure rollers. This arrangement ensures that the work is held in close contact with the conveyor belt, giving safe operation and a uniform thickness to the finished work. A two speed conveyor drive gearbox gives a greater range of finishes and eases the load on the machine. The conveyor belt is of non-marking rubber.
A full width stop bar, mounted on the front of the machine can be reached from almost any position and enables the machine to be stopped quickly when required.
The machine will handle timber thicknesses between 1mm and 133mm and the adjustment is via a handwheel conveniently situated on the top of the machine. A digital read-out scale allows accurate settings to be made, either for the first pass or just a minute tweak for the final finishing pass. Twin 100mm dust ports are provided, efficient dust extraction is vital to the performance of this machine, please make sure that your dust extraction system is adequate. A solid and dependable machine which will rapidly repay its investment in a busy workshop where high volume throughput is the order of the day.
Please ensure that your workshop electricity supply is adequate for these machines. If unsure, seek advice from a qualified electrician. N.B. 16A socket supply is required, (5 pin, 3 x L, N + E for 415V supply).
