Abstract
The invention discloses a vertical CNC deep-hole machining method. The vertical CNC deep-hole machining method comprises the following steps that 1, a CNC machine tool spindle clockwise rotates to guide a drill bit to perform feeding in the axial direction, and a workpiece is machined till the preset guide hole depth is reached; 2, a CNC tool changing arm changes an inner cooling drill bit, the spindle anticlockwise rotates at the speed of 500 turns per minute, a Z-shaft performs downward feeding in the axial direction, meanwhile the center is opened for water discharge, and the workpiece is machined till the guide hole depth is reached; 3, the spindle clockwise rotates at the speed of 500 turns per minute, the Z-shaft performs feeding in the axial direction, the rotation speed of the spindle is improved to 3500 turns per minute when the workpiece is machined to reach the preset speed-increase depth, the Z-shaft performs feed machining in the axial direction to reach the effective depth of a deep hole, the spindle stops rotating, the Z-shaft performs reverse feeding in the axial direction to reach a safe distance, and deep-hole machine is completed. By means of the vertical CNC deep-hole machining method, deep-hole machining can be efficiently conducted on workpieces at high speed.
Description
Technical field
The present invention relates to vertical CNC deep hole processing method.
Background technology
During vertical CNC deep hole processing, because row cuts not smooth, block endoporus, drill bit easily fractures, and depth drill processing due to positioning precision and working (machining) efficiency on the low side, be not suitable for beat batch production model, therefore in the urgent need to finding the deep hole processing method of the high-speed and high-efficiency of a kind of vertical CNC.
Summary of the invention
The object of the present invention is to provide a kind of vertical CNC deep hole processing method, its energy high-speed and high-efficiency ground is to work pieces process deep hole.
For achieving the above object, technical scheme of the present invention is a kind of vertical CNC deep hole processing method of design, comprises the steps:
1) CNC machine main shaft turns clockwise, and guides drill bit feeding vertically, to work pieces process to the bullport degree of depth preset;
2) CNC tool change arm changes interior cold drill bit, and main shaft is rotated counterclockwise with 500 turns per minute, and Z axis, vertically to lower feeding, opens central water outlet simultaneously, to work pieces process to the bullport degree of depth;
3) main shaft turns clockwise, 500 turns per minute, Z axis is feeding vertically, to work pieces process to when presetting the speed-raising degree of depth, main shaft improves rotating speed to 3500 rpm, and Z axis feeding is vertically machined to the effective depth of deep hole, and main shaft stops, feed reversing is to safe distance vertically for Z axis, and deep hole machining is complete.
Preferably, the dark 10-15 millimeter of the described default speed-raising depth ratio bullport degree of depth.
Advantage of the present invention and beneficial effect are: provide a kind of vertical CNC deep hole processing method, and its energy high-speed and high-efficiency ground is to work pieces process deep hole.
Detailed description of the invention
Below in conjunction with embodiment, the specific embodiment of the present invention is further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
The technical scheme that the present invention specifically implements is:
A kind of vertical CNC deep hole processing method, comprises the steps:
1) CNC machine main shaft turns clockwise, and guides drill bit feeding vertically, to work pieces process to the bullport degree of depth preset;
2) CNC tool change arm changes interior cold drill bit, and main shaft is rotated counterclockwise with 500 turns per minute, and Z axis, vertically to lower feeding, opens central water outlet simultaneously, to work pieces process to the bullport degree of depth;
3) main shaft turns clockwise, 500 turns per minute, Z axis is feeding vertically, to work pieces process to when presetting the speed-raising degree of depth, main shaft improves rotating speed to 3500 rpm, and Z axis feeding is vertically machined to the effective depth of deep hole, and main shaft stops, feed reversing is to safe distance vertically for Z axis, and deep hole machining is complete.
The dark 10-15 millimeter of the described default speed-raising depth ratio bullport degree of depth.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
