A machine tool includes a movement device, which has a first feed shaft and a second feed shaft that mutually intersect, and a plurality of tools, which are driven by the movement device and respective blade edges of which are staggered stepwise. The blade edges of the tools are aligned with the second axis due to the inclination of the tools as a unit. The machine tool is capable of executing center level adjustment of a plurality of tools mounted on a tool post against a workpiece having a larger diameter, and is also capable of reducing wasted time in non-cutting operation via equal stroke lengths of the tools.

Machine tool

A mold of a brake pad friction material, including a mold member fitted into a mold frame into which a powder material of the brake pad friction material is put, in which the mold member is configured such that a pressing surface in a surface of the mold member, which forms a region abutting the powder material put into a mold frame, has a concave shape that is formed by being gradually recessed from both end portion sides to a center portion side of the pressing surface.

A main spindle located in a region of a rotary guide bush device where the rotary guide bush device (has been attached to be disposed in a position of a front (F) along an axis (C) direction when the rotary guide bush device having a guide bush, which is supported in a removable manner by a guide bush-supporting base (supporting base) provided in the front (F) along the axis (C) direction of the main spindle, is removed. A seal member (fixed to the guide bush-supporting base has contact with an outer circumferential surface of a main spindle cover over an entire circumference, so that processing with or without the guide bush can be selected and a complicated process required for switching the processing with or without the guide bush can be simplified.

Processing machine

Provided is a machine tool control device which does not require an operator to enter the execution order of machining programs before testing a machine tool, enabling easy debugging of the machining programs. A machine tool control device () sequentially executes a plurality of machining programs (S, S) in a unit of machining program block (S-, S-, S-, S-) to a wait command (da-, da-, da-, da-) in ascending order of the system number () of the machining programs (S, S) without executing machining program blocks (S-, S-, S-, S-) in parallel between the machining programs (S, S).

Machine tool control device

There are provided a workpiece and a gripping mechanism capable of shortening the handling time not involved in machining, shortening the overall time required for producing a plurality of finished members, accurately positioning the workpiece even if there is an axial dimension error, lessening waste of a material and reducing the burden of disposal of discharged chips. The workpiece has a shape in which plural raw blanks that become products by material removal are integrally molded. The gripping mechanism comprises a free moving means that relatively and freely moves a gripper and the workpiece, and a positioning means for defining the axial gripping position of the gripper and the workpiece.

Workpiece and gripping mechanism

To prevent entrance of swarf or cutting oil from a workpiece recovery opening, in a workpiece recovery unit, a coverwhich covers an upper side and a lateral side of a workpiece recovery openingopening in an upper side of a workpiece recovery sectiondisposed lateral to a holderwhich holds a processed workpiece', a workpiece transport pathfrom an entranceopening in a lower side provided in the coverto the recovery openingis formed in a step-like shape, the holderis supported so as to be movable in an up-and-down direction and a right-and-left direction, the workpieceis moved along the transport pathby the holder, and is transported to the upper side of the recovery openingfrom the entranceso as to be recovered in the recovery opening

Workpiece recovery unit

A method for machining a work in a work machining apparatus provided with a movable main spindle moving between a work supply position and a work take-out position, includes arranging a tool rest on the movable main spindle to move integrally with the movable main spindle, supplying the work at the work supply position to the movable main spindle, moving the movable main spindle from the work supply position toward the work take-out position, machining the work held on the movable spindle with a tool of the tool rest while moving the movable main spindle from the work supply position toward the work take-out position, and taking out the work at the work take-out position from the movable main spindle.

Work machining method

There is provided a workpiece separation apparatus permitting input of a mixture of workpieces and chips stably within a flow current and separating them accurately and efficiently. The workpiece separation apparatus includes an input cylinder inserted within a separating container, and a fluid supplying means arranged so as to supply fluid to the separating container from a part lower than a lower end of the input cylinder, and configured such that the fluid overflows and flows out of the upper end of the separating container due to a flow current generated within the separating container, and such that the level of the fluid rises up in the input cylinder and the fluid does not flow out of the upper end of the input cylinder, but is maintained substantially in a resting state and at a level above the level of the upper end of the separating container.
