Belt grinding of titanium

Relevance

Finishing of curved surfaces of parts made of titanium alloys is carried out by belt grinding. The advantages of using abrasive belts include the possibility of machining with surface, or linear contact. This greatly reduces the number of forming movements on the machine.

Grinding

This is a method that is produced by compressor GTE abrasive wheels and wide abrasive belts. Machines MB-885, 381ZD, KSH-185, KSH-186 are designed for this purpose. In the process of picking up the belt bar they simultaneously grind the machined surface on one side. The difference - high productivity and wide use in industry for grinding parts of small size.

Stitching method

For blades with a feather length of more than 120 mm, the string method is suitable, using narrow abrasive belts. Machining is carried out with the stitching method on machines LSh-1, LSh1A, 4ShSL-7, LSh2. A longitudinal stitching is carried out with the direction of feed of details strictly perpendicular to the plane of movement of abrasive belts used.

Part delivery

Longitudinal feed of the part S is carried out due to forward and backward movements of the machine table. And the circular feed will provide discrete rotation of the workpieces around the axis. During the machining process, the LSh-1 machine tool must be set to a certain contact pressure force between the abrasive belt, which is regulated by compensating springs, and the workpiece to be machined.

Copying and method of running-in

It is used to grind intersecting surfaces mated in radius. This principle is the basis of operation of such machines as: ZLSH-9 (ZLSH-91), ZLSH-5 (ZLSH-52) and some others. The workpiece to be machined must fit the standards for the plunging surface. A force of 50-100 N is applied to the contact copier. The belt tension force will be 10 to 30 N for every 10 mm of the belt width.

Rolling method

Complete machining of parts is carried out by the method of running-in, for this purpose a linear contact is used. During machining the shape of the tool will be mated to the surface shapes of the part being machined. This is done by rolling over the part using a defined trajectory.

Diamond Grinding

It was thought that grinding titanium alloys with diamond wheels because of the chemical affinity of carbon and titanium would be ineffective - leading to severe wear of the diamond grains and "sharpening" of the tool. Diamond grinding generates tensile residual stresses in the surface layer. Today, diamond wheels with special metal bonds have already been created, which synchronize smoothing of the cutting grains and cutting them out of the bond, that is, the diamond wheel will be self-sharpening. Grinding of this kind is now quite successfully used in the grinding of blades' nibs on compressors in the production of MMPP Salyut.

Electrochemical grinding

A variation of diamond grinding can be regarded as machining the part using direct current. The process takes place in an electrolyte, and a diamond wheel serves as an anode. This method makes it possible to maintain constant cutting properties of the diamond wheel. Electrochemical grinding generates favorable compressive stresses on the surface of the workpiece.
