DECKEL FP1 PDF

Deckel FP1 Mk. This version was also copied and sold as the "Yukon" Continued: Angular Spindle Head An interesting accessory, designed to machine into places that would otherwise have been impossible or very difficult to get into, the Angular Head was fitted as standard with a No. The head could be swivelled degrees about both its longitudinal and vertical axis, so allowing the tool to be set at any desired angle "in space" - not quite up to the ingenious flexibility of the system used on the very much heavier French-built multi-swivel Hure miller, but not far off. Corner Milling Spindle Head Another unit intended for use in workshops producing mould and die tooling where access to internal corners and edges was difficult.

Should you come across any of these makes and models all will provide "The Deckel Experience" - though you must bear in mind that spares are unlikely to be available and, being complex, finely-made mechanisms, they can be difficult and expensive to repair..

This could be set by the operator to give 8 speeds in one direction or 4 forwards and 4 reverse. The original FP1. Note the very large micrometer dials and lack of a "Stickshift" table control lever and the first "stickshift" model is announced.

The knob on the end of the long power-feed direction and engagement lever can be seen between the two speed-control handles on the right-hand face of the machine. General Layout Constructed in an ingenious way, the layout of the spindle-drive system was both compact and effective: the top of the main column was machined as a slideway to carry a separate housing that doubled to mount a horizontal milling arbor or act as a base for the various heads or a horizontal milling overarm.

The chrome-nickel alloy spindle was case hardened and ran in bearings that provided both excellent support and an easy means of adjustment. To solve the problem of how to drive the spindle when its housing was moved forwards and backwards to provide lateral travel to the cutter , a long fixed gear was mounted parallel to and beneath it on the final-drive shaft and the upper gear allowed to slide along it.

A word of warning for users of the English-made Alexander "Master Toolmaker" who might want to fit a Deckel head - the Alexander drive gear has a degree pressure angle whilst that of the Deckel is Besides normal horizontal and vertical milling operations, all models were available with a range of accessories to cover slotting, jig boring, jig grinding, spiral milling and punch milling. Drive System for Head and Table Cleverly arranged so that the table-feed rates were completely independent of spindle speeds, the drive system on the Deckel began with a two-speed, 3-phase motor mounted at the back of the machine on an easily reached, completely open and height-adjustable cast-iron platform.

The table-feed gearbox was mounted inside the column, below the spindle-drive gears, and had eight speeds; used in conjunction with the two-speed motor this arrangement gave 16 rates of feed, the fastest of which, the makers suggested, was quick enough to use in place of a proper power "rapid-traverse". Whilst the rate of table feed was set by either pick-off gears or later two levers or a dial, on all versions except the prototypes the direction of movement was controlled by an unusual for a machine tool ball-handled rod, rather like a car gear-change lever - what the Americans would refer to as a "stickshift".

The lever controlled the movement of the main "vertical table" through eight different directions - left, right, up, down and a further four combinations where, with both horizontal and vertical feeds engaged at once, the table would move diagonally at an angle of 45 degrees. The table feed screws were all precision ground, ran though large bronze nuts and were fitted with exceptionally clear, finely engraved satin-chrome finish micrometer dials.

Built-in steel rulers were provided for each axis of movement which, in combination with holders to accept dial-test indicators and gauge blocks, allowed high-precision measurements by co-ordinates to be made, independent of the feed screw readings.

On the earliest model, to protect the table-drive mechanism against overloads, a shear pin was fitted hidden under a slip spring above the coolant pump. All gears, and their shafts, both spindle and table drive, were hardened and ground-finished.

The "Y" movement was, of course made by the head, the travel being in the order of mm. A simple Slotting Head was also listed. The maximum clearance between spindle axis and inner face of the main column was 11 inches mm. Unfortunately, the head had exactly the same range of 16 speeds from 40 to rpm or 95 to r. To get round the problem Deckel offered an alternative head, the "High-speed", powered by a 0. Fitted with a 40 INT nose the head could be swivelled 45 degrees either side of central and, because the unit was self-motorised and did not require connect to the horizontal spindle-mounted drive gear, the base was able to be made extra long to provide a useful 7.

Unfortunately, instead of equipping the High-speed head with a long-travel quill with fine-feed control, Deckel used the same annoyingly restricted unit from the standard head - a design decision that operator charged with the delicate handling of small cutters found most frustrating.
