The present invention has an object to provide a tool replacement system that is capable of preventing the waiting time from occurring as much as possible although an intermediate magazine arranged therefore has a smaller capacity than prior arts. In the tool replacement system, programs pertaining to the sequence of operation and operation time of operating tools 7 are established, wherein, when the operation time of individual tools 7 is shorter than the conveyance time for reciprocation of the tool conveyance apparatus 3 between the tool magazine 1 and the tool replacement arm 4, the object can be solved by realizing transfer of at least a part of the tools planned to be operated in a next process of the corresponding individual tools 7 to the tool replacement arm 4 after the tools are arranged to the intermediate magazine 5.

Disclosed is a clamp of less waste instruction method for an addition axis, which omits instructions for clamping and unclamping and working in response to those instructions, thereby improving the working efficiency of movement of a work piece and working on the work piece with a tool in the overall machining. The clamp instruction method for an addition axis comprising the steps of, at a stage of working a work piece with a tool, measuring a rotational torque generated by the working with respect to the addition axis coupled to a table which supports the work piece or a pallet having the work piece mounted thereon; and generating a clamp instruction to the addition axis when the rotational torque exceeds a predetermined reference value as is the embodiment of the clamp wherein prior to working with the tool, it is determined whether the tool is a load tool whose working generates a rotational torque on the addition axis found beforehand to exceed a set reference value, and when the tool is the load tool, the clamp instruction is generated before working with the load tool or as is the embodiment of the clamp wherein when two addition axes of different directions are coupled to one table, selection of whether or not the clamp instruction for one addition axis is needed and generation of the clamp instruction when needed, and selection of clamping for the other addition axis and generation of the clamp instruction when needed are effected at approximately same timings.

A plurality of rollers (4) are arranged between the inner and outer races (2,3) so that the distances between the rollers can be freely changed without a retainer. Since there is no retainer, any abrasion of the retainer due to the frictions between the rollers (4) and the retainer is not caused, the number of the rollers (4) can be increased, and the carrying capacity can be increased so that the roller (4) bearing with a longer life time can be obtained.

A pallet exchanging apparatus for machine tool used for exchanging the pallet loaded with the machined workpieces with the pallet loaded with the workpieces to be machined. The pallet exchanging apparatus has a transmission device for shifting the pallet between a work position on a table of the machine tool and a waiting position for exchanging the pallets. The transmission device is drived either of the movement of the table or the movement of the driving means for the table and is adapted to output the rotational movement. The output of the transmission is used for dtiving a speed-up device. The speed-up device is adapted to move the pallet linearly with high speed and larger stroke than those of the linear movement of the table.
