摘要： In adjusting phase for work (W), the operation of mounting/dismounting a reference tool on a spindle (6) is dispensed with and so is a storage space for the reference tool, and besides, it is arranged that the thrust on the work (W) does not directly act on the spindle (6) at the time of this phase adjustment. In a machine tool in which a spindle housing (7) supporting the specifically directed spindle (6) for rotation alone is supported for parallel motion in orthogonal three-axis directions (XYZ) by a numerical control mechanism (4), in determining the phase for the work (W) to be feed-rotated around a specific axis (S), it is arranged that with a reference block (9) fixed to the spindle housing (7), the work (W) is feed-rotated around the specific axis (S) to abut the phase reference section (W1) of the work against the reference block (9), so as to find the amount of feed-rotation of the work at the time of this abutment.

摘要： A boring control method for a machine tool for automatically boring a deep hole using central control means performing boring with programmed control. In the boring, the number of processing and steps of the machine tool is kept minimum, load torque of a tool is detected continuously using torque detection means, and the movement of the tip portion of the tool desired for a piece of work is confirmed from a reference point to a hole bottom using a Z-axis movement device. The boring is continued in each step until the load torque exceeds a predetermined torque limit value, performed in a condition where a main shaft rotation number, or rotation speed of the tool, and feed speed form a specific pattern, and a condition is set where a total step number (f) does not exceed a predetermined limit step number (N).

摘要： A main shaft (6) movable in a direction of Z-axis is provided at a position on one side of a foundation (1). A rotation support shaft (10) is provided at a position on the other side of the foundation (1), and a lateral stand (12) is fixed on the top portion of the rotation support shaft (10). On the upper surface of the lateral stand (12), there is provided a work grip rotation feed mechanism portion (13) for rotating bar-like work (w) about a specific lateral axis (S) on the upper surface. The rotation support shaft (10) and the specific lateral axis (S) are horizontally separated by a required distance (L0). The rotational position of the rotation support shaft (10) is varied between the case where the bar-like work (w) is attached to and removed from the work grip rotation feed mechanism portion (13) and the case where the bar-like work (w) is processed by the operation of the main shaft (6).

摘要： An apparatus for supplying cutting liquid automatically according to optimal cutting liquid supply conditions, including variation with time during operation, predetermined for every tool of a machine tool. Optimal supply conditions of the cutting liquid supply (Q) are preset in a control means (5) for respective types of tools (1). The control means (5) comprises a main control section (5a) for mainly controlling the driving of a spindle unit (2) equipped with the tool (1), and an automatic supply control section (5b) for controlling the cutting liquid supply (Q) automatically, wherein the automatic supply control section (5b) delivers an input signal (Vin) corresponding to a supply condition (preset) to a variable frequency generating means (5c). The variable frequency generating means (5c) generates an output frequency signal (F) corresponding to the input signal (Vin) and delivers it to a cutting liquid supply means (3). The cutting liquid supply means (3) supplies a cutting liquid in amount (Q) proportional to the output frequency signal (F) to the tool (1) from a cutting liquid tank (3a) using a supply pump (3c).
