JP3009321U - Spindle rotary drill polishing machine - Google Patents

Abstract

(57) [Summary] [Purpose] It can be provided at a lower cost than conventional drill polishing machines.
The purpose is to make it easy for beginners to polish the drill. [Structure] A drill grinder consisting of a main spindle device and a No. 2 diameter feeding device, and the handles of both devices work together at the same time.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to polishing of various metal working drills.

[0002]

[Prior art]

 Conventional polishing machines are complicated in operation, difficult for beginners to use, and expensive.

[0003]

[Problems to be solved by the device]

 The object of the present invention is to provide a polishing machine which is easier to operate and less expensive than conventional polishing machines.

[0004]

[Means for Solving the Problems]

 With the interposition of a support fitting having a screw threaded and inserted into the main spindle and a support fitting screwed into the main spindle, it is possible to facilitate drill polishing by interlocking with this structure and with a second diameter feed device.

[0005]

[Action]

 Since the spindle spindle rotates forward and backward, the chisel edge angle can be finished well.

[0006]

【Example】

 When the grindstone hits the No. 2 diameter with the No. 2 diameter feeder and the grindstone hits the entire surface, the flank can be sharpened simply by reversing the spindle spindle. After that, the opposite side is also polished in the same way, and finally, the lengths of the left and right cutting edges are confirmed to be the same and completed.

[0007]

[Effect of device]

 Since the chisel edge angle and the secondary angle, which are difficult for beginners, can be polished uniformly, the blade can be held well and there is no burr after drilling, so the process can be saved and the work process can be shortened.

Claims (3)

[Scope of utility model registration request] 1. A Jacobs chuck is attached to one end of a spindle, a screw is cut on the other end of the spindle, and a support fitting is screwed into the spindle. The spindle handle is rotated to move forward and backward to move the second angle and the third angle. Spindle spindle device for smooth polishing. 2. A device for advancing the second diameter of a drill until it hits the surface of a grindstone, and for moving forward and backward when attaching and detaching the drill. The latter is able to perform a large back and forth movement by the slide system. Also, by providing an inclination from the pedestal, 1
The 2nd diameter feeding device that can freely set the polishing angle when polishing the 2nd and 3rd angles. 3. A drill polishing, characterized in that a main spindle device is attached to a fixing metal fitting on a column of the second diameter feeding device, and a rotary motion and a forward / reverse motion are interlocked by operating a handle of both of them. Machine.
