Description

technical field

[0001] The invention relates to the field of surface treatment devices for inner holes of parts, in particular to an electric control device for processing inner holes of parts. Background technique

[0002] Parts with large depth and small diameter inner holes are widely used in the fields of machinery, metallurgy and materials, such as hollow shafts, steel cylinders and pipe fittings. Such parts often require surface treatment such as shot peening, paint removal, rust removal, and polishing on the inner wall surface during manufacture, use, and maintenance. Shot peening, the method is to carry out surface treatment by shot peening, which has a large impact force and obvious cleaning effect. Generally, cast steel shots with better toughness are used.

[0003] Due to the pneumatic shot peening or sand blasting of the surface of the inner hole with a large depth and a small diameter, this type of surface treatment often encounters the following difficulties. ...
