Abstract: 1351015 Lathes; machine tool details IKEGAI TEKKO KK 19 April 1971 [23 Feb 1970(2) 23 March 1970] 22752/71 Headings B3B and B3T [Also in Divisions G3 and F2] A programmed numerically controlled lathe has a spindle unit 101, with hydrostatic spindle bearings 112, (113), Fig. 9 (not shown), and thrust bearing 114. Each spindle bearing has two pairs, P 1 , P 2 ; (P 3 , P 4 ), Fig. 10 (not shown), of pockets, the thrust bearing having annular pockets P 7 , P 8 , all containing oil under pressure supplied via restrictors. The pressure required to maintain fluid support is detected in at least one of each pair of pockets, and passed via solid state or piezo transducers 124-126 and amplifiers 127-129 to unit 130 which computes by vector addition the resultant force acting on the spindle, and its time rate of change, the latter detecting for example a broken loose, or chattering tool, or irregularities of form or hardness in the workpiece. Should either of the latter two quantities pass outside respective upper and lower limits, the decoder and store 133 modifies the original programme from tape reader 132, to either change lateral and longitudinal feed rates, or stop the feed. The relevant part or all of the programme may be repeated to produce the required workpiece shape. Stepping motors 136, 142 receiving pulses via pulse interpolation circuit 134 and output circuit 135, provide the feeds. Hydrostatically supported cross-slide.-The cross-slide (4), Fig. 3 (not shown), of a programme controlled lathe is hydrostatically supported by oil pressure in pockets (P 1 -P 4 , P 11 -P 44 ), Figs. 4, 5 (not shown), and the downward force on the cross-slide, and its rate of change, due to the tool (6) is measured in terms of the pressures in pockets (P 1 , P 2 ) or P 1  alone and kept within predetermined limits in the same way, see Fig. 6 (not shown). The system may be applied to the table of a milling, or boring, machine. Hydrostatic hearing for the lathe.-Figs. 7, 8 (not shown), the pocket (54) contains oil under pressure, and a discharge groove (58) surrounding the pocket passes excess oil back to the supply. Channel (59) contains high pressure gas which keeps the oil within the bearing and keeps foreign matter away. A similar bearing (55, 59, 60) is provided below the slider face (51) and may move with respect to the first.
