Numerically controlled machine

Abstract

The invention relates to an nc machine which includes a body, a small splint, a machine head, lead rails and a slope of a bottom foot. The lower part of the body is connected with the base of the machine. The machine is characterized in that the lower part of the base of the machine is the slope of the bottom foot; the slope of the bottom foot is in a certain angle with a horizontal and extends outside the two sides of the machine; the upper part of the body is provided with the machine head; the other side of the machine is provided with a tailstock; the external end part of the tailstock isconnected with a handwheel which is provided with a rocker; an electric knife rest is arranged between the machine head and the tailstock that is positioned above the body; the lower part of the electric knife rest is overlapped with the small splint and a large splint in turn; the small splint is long enough so as to ensure the small splint can completely cover the surface of the lead rail at the lower part when the small splint moves; the lead rails are arranged at the two sides of the periphery of the machine head. The nc machine has the beneficial effects of playing a certain protection role on the lead rails; increasing the length of the small splint, thus preventing the error of processing caused by the scattering of scrap iron; increasing the space for discharging scraps.

Description

technical field [0001] The invention relates to a numerically controlled machine tool. Background technique [0002] With the development of numerical control technology, higher requirements are put forward for the productivity, machining accuracy and service life of machine tools combined with control methods and usage characteristics. However, existing machine tools have certain defects in the protection of guide rails of numerical control machine tools. Traditional machine tools have not taken good protection measures for the guide rails. The design of the machine tool itself is incomplete. The short length of the guide rails makes the protective cover unable to move forward and backward to both sides of the bedside due to space constraints; existing products support The plate part is short. When the small pallet moves through a certain stroke, part of the guide rail surface will be completely exposed, and it is easy to cause iron filings to fall on it and cause errors in...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a numerically controlled machine tool to overcome the disadvantages of the prior art that there are no good protection measures for the guide rail, the error of the processing result caused by the easy scattering of iron filings, and the small space for chip removal.
