Variodrill High Speed Drilling Machine

The Variodrill is a high speed machine which combines drilling accuracy with an increased level of operator comfort. The spindle, which has a speed of 10,000 to 30,000 rpm, is located below the work table. The drilling cycle is initiated by pressing a foot switch, thus leaving both hands free to posi-tion the printed circuit board. The feed rate is continuously adjustable by means of a potentiometer at the front of the machine. Sighting of the drill is achieved by positioning the PCB so that the pad to be drilled is located beneath a target in a perspex plate fixed above the work table. Accuracy is increased by viewing the target through a magnifier. The machine rests on an adjustable base which allows the work table to be tilted towards the operator, thus reducing operator fatigue. The Variodrill is supplied as standard with a dust extraction unit which connects to the rear of the machine for effective removal of drilling debris. Please note : Only drill bits without collars are suitable for use with the Variodrill.

FX-5 High Speed Drilling Machine

The FX-5 is a compact, high speed printed circuit board drilling machine, designed primarily for the development engineer, PCB manufacturer, or model shop. Its high accuracy and ease of operation make it ideal for drilling prototypes and small batches of PCBs. The machine is of a robust steel construction and features an integral fan to assist swarf removal. A work illuminating lamp, spring plunger for stack drilling and an adjustable dead-stop attachment are also included. The FX-5 offers a choice of two fixed operating speeds : 14,000 rpm or 18,000 rpm, switchable by means of a toggle switch on top of the machine.

Please note : The FTX drills are non-stock build to order with an approximate manufacturing lead-time of up to 12 weeks.

FX-5R PCB Routing Machine

A modified version of the FX-5 Drilling Machine also suitable for routing PCBs. The machine has a fence and depth stop and is fitted with special bearings, allowing it to withstand heavy side loadings. The router is ideal for making cut-outs in edge connectors, shaping complicated contours, removing unwanted tracks, or chamfering rough edges of circuit boards. Specifications Spindle Speeds 14,000 rpm, 18,000 rpm Dimensions (mm)   L420 X W200 X H400 Throat clearance 150mm Chuck capacity 0.5-4mm Height under chuck 44mm Electrics 220-240V 50Hz 1ph

FTX Optical Drilling Machines

The FTX Optical Drilling Machine has been designed to provide all the advantages of accurate optical drilling at a relatively low cost, yet without compromising precision or ease of use. The machine is electro-pneumatically controlled, with a large screen optical unit, high intensity illumination and clear definition to minimise operator fatigue. The projector unit gives a balanced magnification of 7:1, while workpiece illumination is provided by two high-intensity lamps, which can be easily adjusted for optimum light concentration.

Air is introduced to the machine by means of a separate three-positioned isolating switch. Depression of the two-position foot switch clamps the circuit board, allowing the operator to check the accuracy of alignment of the board to the screen centre. The machine features parallax style optics; a board moved left to right appears from the opposite side of the screen. Further depression of the foot switch initiates the drilling cycle and on completion, releases the clamp for the next operation.

The automatic drilling spindle has an adjustable feed rate for all sizes of drilled holes. A retractable bellows unit surrounds the chuck and is connected to an outlet pipe at the rear of the machine for connection to a swarf extraction unit (not included). The large capacity key-type drill chuck is easily accessible for drill changing by pivoting the counter balance projector head back-wards. The matt finish steel base plate incorporates a drill bush adapter which accepts most standard drill bushes. The unit is mounted on a rigid cantilever-type stand with a large laminated work top which provides ample work space. A drawer is provided for convenient storage of drill bits, tools and accessories.
