Dual-edge dual-way cutting numerical control wood turning tool

Abstract

The invention discloses a dual-edge dual-way cutting numerical control wood turning tool. The dual-edge dual-way cutting numerical control wood turning tool mainly comprises a tool bar and a replaceable tool bit. The tool bar is formed by special tempered carbon steel. The tool bit is designed to be a forward and reverse dual-way symmetrical cutting edge. A main cutting edge and an auxiliary cutting edge are spaced. The tip of the auxiliary cutting edge is 0.1-0.2 mm closer to the machined surface compared with the tip of the main cutting edge, and the width of the auxiliary cutting edge is 1-3 mm. The tool cutting edge angle is 75-90 degrees, the tool minor cutting edge angle is zero, the edge inclination angle is zero or negative and is implemented through the inclination angle of the installation position of the tool bit in the tool bar, the anterior angle is about 45 degrees, the relief angle is 10-15 degrees, and the end relief angle is 1-2 degrees. The surface of a tool bit matrix is coated with one or more composite hard abrasion-resistant coatings through a vapor deposition method. The dual-edge dual-way cutting numerical control wood turning tool provided by the inventionperforms cutting easily, is low in cost and long in service life, and is used for the procedures of blank forming, outer circle turning, end face turning and the like of soft non-metal materials suchas wood and plastics.

Description

technical field [0001] The invention relates to the fields of wood product processing, mechanical processing, cutting tools and the like, in particular to a double-edged bidirectional cutting numerical control woodworking turning tool. Background technique [0002] Wood spinning is not so much a technology as an art; natural wood materials, fiber texture, hardness and other physical properties vary widely; even adjacent parts of the same piece of wood may have huge differences in physical properties, so To create a perfect wooden spinning work, the operator communicates uninterruptedly with the spinning wood through eyes, ears and hands, and uses the turning tool in his hand to have a subtle and dynamic continuous dialogue with the wood, thus making the wood into the imagination in his mind shape. [0003] Therefore, the traditional wood turning technique has higher requirements on the operator's technical and artistic level; moreover, the operator's labor intensity is rela...

Problems solved by technology

[0003] Therefore, the traditional wood turning technique has higher requirements on the operator's technical and artistic level; moreover, the operator's labor intensity is relatively high, and the product processing efficiency is low; practice has proved that CNC processing technology can reduce labor intensity, improve processing accuracy and It has absolute advantages in processing efficiency and other aspects; for most wood product processing, except for some parts and their process links that require manual work, most of them can be completed by numerical control processing technology; however, for soft non-metallic materials such as wood and plastic, turning There is very little research and development of CNC tools with replaceable machine holders, especially easy-cutting, low-cost, and long-life turning tools
