Pinondo Shapers - Spain


With a main body and all sliding parts cast from a pearlitic cast iron with a hardness of Brinell 190/220, Pinondo shapers were built in wide range of eleven sizes with ram strokes of 320, 365, 460, 525, 550, 625, 650, 750, 850, 1000 and 1200 mm. Even on the smallest models, ways were finish ground and lubricated - as were all the inner mechanisms - by a gear pump that circulated SAE 30 oil - a sight glass being provided for the operator to check the flow. Although the system was automatic, it was recommended that, at the start of the day, the oil-feed regulating valve be moved from its working "Position 1" to "Position 4" to thoroughly oil all parts, and then returned to "1" for the rest of the shift..
Gears and shafts (the latter turning in high-quality ball races) were all in a heat-treated, chromium-nickel steel - with strengths of up to 90/100 kg/mm2.
Six carriage feeds were fitted, both across and vertically, adjustable from 0.1 to 0.6 mm and, instead of an ordinary clapper-type box to lift the tool on the return stroke, a lever-operated automatic lifter was fitted. Controlled by either one or two levers towards the rear of the shaper's right-hand face, the gearbox gave four speeds with an additional four speeds are obtained by means of multi-speed electric motor. Drive to the crank passed through a multi-disc clutch with a brake - this appearing to be in the form of a conical steel-to-steel taper.
Able to be rotated through 90 each side of level, the table on the smaller models - Types 330 and 350 - was overhung at the front but on all others an angle-plate support was provided, this being secured by two long locking leavers that allowed a quick and convenient method of changing the setting. Fitted as standard was a robust, swivel-base machine vice with two tennons on its base that located into the table's T-slots..
