Description

Technical Field

[0001] The utility model relates to the technical field of CNC lathes, in particular to a composite horizontal inclined bed CNC lathe. Background Art

[0002] CNC lathe is one of the important equipment in the field of modern mechanical processing and is widely used in various manufacturing industries. Its main feature is that it can control the movement trajectory of the tool through programming to achieve precise processing of the workpiece. There are various structural forms of CNC lathes, among which the most common are vertical and horizontal. These two structures have their own characteristics and are suitable for different processing needs;

[0003] For example, the slanted bed precision horizontal CNC lathe with row cutters with publication number CN217370472U belongs to the technical field of turning equipment. The lathe uses an inclined bed, which is conducive to the discharge of cutting fluid and chips. A chip guard assembly is arranged on one side of the Z-axis support plate. The chip guard assembly moves synchronously with the feed of the Z-axis support plate to timely intercept the larger chips generated during the cutting work, and at the same time protect the inclined bed, the screw guide rail and the Z-axis support plate; an overflow chip guard groove and a fine chip filter plate are arranged on the front side of the base to finely filter the cutting fluid, wherein the installation height of the direct filter part of the fine chip filter plate is lower than the overflow part, and the cutting fluid filtered by the coarse chip filter flows into the direct filter part and is filtered through the direct filter part. When the cutting fluid flow is large or the direct filter hole is blocked, the cutting fluid is filtered from the overflow parts on both sides, so that the utility model is suitable for working conditions with large cutting fluid flow;

[0004] The lathes in the above-mentioned comparative documents use an inclined bed, which is conducive to the discharge of cutting fluid and chips.
