Pneumatic Slot-Cutting Machine for Window Shutters

• Pneumatically operated throughout
• Automatic programmer allows programming of spaces without slots
• 15 steps can be carried out with just one toothed rack
• Bits shifted sideways while uprights remain stationary
• Slot depth up to 1"
• The GAL/4P window shutter slot-cutter is designed to provide average or high output and is the only machine of its type capable of cutting slots of standard kinds in roller blind uprights with a single toothed rack.
• One of the main features which distinguishes the GAL/4P from conventional slot-cutters and from which its improved performance is derived is the fact that the uprights themselves remain stationary while the bits are shifted sideways.
• The moving parts run on sealed ball bearings. The spindle carriage runs backwards and fowards on steel guides.
• The cutting interval is adjusted by means of a device acting on a toothed rack having constant pitch of 1/4" to set the following cuts at a multiple of this distance, with a maximum interval of 3 27/32".
• Slot depth, length, angle and position on the upright being processed are easily adjusted.
• All the various processing phases, from the activation of the clamping device to piece feeding and drill-bit advance, are carried out by means of a synchronized automatic pneumatic mechanism.
• The speed at which the bits penetrate the wood is maintained constant and is regulated by means of a hydraulic device with micrometer measurement able to operate correctly even in the presence of variations in pressure. The same device also allows the speed to be regulated in relation to the hardness of the wood being processed: this feature, together with the very high drill-bit rotation speed, ensures that the pieces processed are perfectly finished.
• The model GAL/4P machine is fitted with a device which allows a preset space (equal to the interval between slots or a multiple of this distance) to be left without slots in the center of the upright. It is also complete with an automatic device which stops the machine when processing is complete.
