Abstract

PROBLEM TO BE SOLVED: To constantly retain the outflow angle of chips to a work piece and to stably obtain high working accuracy by providing a chip treating machine movably in the axial direction of the work piece synchronously to a tool rest. SOLUTION: A cutting blower 3 is driven in the axial direction of a work piece W synchronously to a tool rest 2 in a state with a sucking port 3A directed to the outflow direction of chips C, by a slide bed 8 following the start of turning the outer surface of the work piece W. Consequently, the chips C are sucked into the sucking port 3A of the cutting blower 3, in the constantly retained condition of an outflow angle. Thus the outflow angle of the chip C can be nearly constantly retained during turning the outer surface of the work piece W with the rectilinearly continuing chips C thereby forming a fixed finished surface, also stably obtaining high working accuracy.

It is difficult.

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide an apparatus for finish-turning an outer peripheral surface of a cylindrical or columnar work, and to stably obtain high machining accuracy. It is an object of the present invention to provide an external finish turning apparatus capable of performing the above.

In order to achieve the above object, an external finish turning apparatus according to the present invention is an apparatus for finish turning an outer peripheral surface of a cylindrical or columnar work with a cutting tool. A tool rest that is fixed and movable in the axial direction of the work, and a chip processing machine that suctions and discharges chips of the work flowing out from the cutting edge of the cutting tool, wherein the chip processing machine is synchronized with the tool post. And is configured to be movable in the axial direction of the workpiece.

The external finish turning apparatus of the present invention is suitable for performing a finish turning on the outer surface of a drum for an electrophotographic photosensitive member as a work.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An external finish turning apparatus according to the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a schematic structure of an external finish turning apparatus.

As shown in FIG. 1, the external finish turning apparatus of the present invention is an apparatus for finish turning an outer peripheral surface of a cylindrical or columnar work (W) with a cutting tool (1).
A tool rest (2) that fixes the workpiece and can move in the axial direction of the work (W), and a chip processing machine that suctions and discharges the chips (C) of the work (W) flowing out from the tip of the cutting tool (1). Cut blower (3). The cut blower (3) is configured to be movable in the axial direction of the work (W) in synchronization with the tool rest (2).

The work (W) includes, for example, a drum for an electrophotographic photosensitive member used in a copying machine, a printer, or the like. Such a drum is usually made of a metal material such as aluminum, brass, and stainless steel. The outer diameter of the drum is about 15 to 110 mm, the inner diameter is about 10 to 105 mm,
The length is set to about 200 to 500 mm.

The cutting tool (1) is a sword cutting tool for finishing. Usually, a solid cutting tool or a cutting tool having a cutting edge integrally formed with a shank having a rectangular cross section is used. It may be an assembly tool that is detachably fixed. Such a cutting tool (1) is fixed to the tool rest (2) along the shank in the radial direction of the work (W).

The tool rest (2) is fixed on a slide stage (5) which is set on a bed (4) and is movable in XY directions. When the slide stage (5) is driven and controlled in the X and Y directions via a drive mechanism (not shown), the cutting tool (2) and the cutting tool (1) are driven in the X and Y directions, and a predetermined position with respect to the work (W). The cutting amount and the feeding amount are given.

On the bed (4), a pair of spindle heads (6) that hold and rotate both ends of the work (W) are mounted. The operation of the spindle head (6) and the slide stage (5) is controlled by operation of an operation panel (7).

The cut blower (3) is provided with a suction port (3A) for sucking the chips (C), and finely breaks the linear chips (C) sucked from the suction port (3A) to discharge the chips (C). 3B). The outlet (3
B) is connected to a dust collector (not shown) via a flexible tube or the like. The cut blower (3) is mounted on the slide bed (8) with its suction port (3A) directed in the direction in which the chips (C) flow out.

The slide bed (8) is provided with a feed screw mechanism (8A) for driving the cut blower (3) in the axial direction of the work (W). The feed screw mechanism (8A) has a drive motor (not shown) whose operation is controlled in synchronization with a drive mechanism (not shown) for driving the slide stage (5) in the Y direction, and a work (W). The cut blower (3) is configured to be driven in synchronization with the movement of the tool post (2) along the axial direction.

Next, an example of use of the external finish turning apparatus according to the present invention will be described. In the external finish turning device of the present invention, as shown in FIG. 1, both ends of a work (W) are driven to rotate by a pair of spindle heads (6), and a tool rest (2) to which a cutting tool (1) is fixed is provided. The outer surface of the work (W) is turned by the cutting tool (1) by being driven in the XY directions by the slide stage (5).
In this case, the turning conditions such as the rotation speed of the work (W), the cutting depth of the cutting tool (1), and the feed speed are controlled by the operation from the operation panel (7) so that the chips (C) are linearly continuous. Is set.

With the start of the turning of the outer surface of the work (W), the tool post is set with the cut blower (3) with the suction port (3A) directed to the outflow direction of the chips (C) by the slide bed (8). The workpiece (W) is driven in the axial direction in synchronization with (2). For this reason, the chips (C) are supplied to the suction port (3) of the cut blower (3) while the outflow angle is kept constant.
A) is sucked. Then, the sucked linear chips (C) are finely broken inside the cut blower (3), discharged from the discharge port (3B), and sent to a dust collector (not shown) via a flexible tube or the like. Collected.

As described above, in the present invention, the outflow angle of the chips (C) is kept substantially constant during the turning of the outer surface of the work (W) in which the chips (C) are linearly continuous. A uniform finished surface can be formed, and high processing accuracy can be stably obtained.
