Magnetic Abrasive Finishing of Beta-Titanium Wire Using Multiple Transfer Movement Method

Abstract

Titanium is often used in various important applications in transportation and the healthcare industry. The goal of this study was to determine the optimum processing of magnetic abrasives in beta-titanium wire, which is often used in frames for eyeglasses because of its excellent elasticity among titanium alloys. To check the performance of the magnetic abrasive finishing process, the surface roughness (Ra) was measured when the specimen was machined at various rotational speeds (700, 1500, and 2000 rpm) in the presence of diamond paste of various particle sizes (0.5, 1, and 3 μm). We concluded that the surface roughness (Ra) was the best at 2000 rpm, 1 μm particle size, and 300 s processing time, and the surface roughness of β-titanium improved from 0.32 to 0.05 μm. In addition, the optimal conditions were used to test the influence of the finishing gap, and it was found that the processing power was superior at a gap of 3 mm than at 5 mm when processing was conducted for 300 s.

A Review on Surface Finishing Techniques for Difficult-to-Machine Ceramics by Non-Conventional Finishing Processes

“…Unlike conventional processes, the non-conventional finishing processes have major advantages in that they use the extremely low normal force with small cuts produced by micro abrasive tools, which enables the production of a superior surface finish and a damage-free surface [ 75 ]. Additionally, these processes can also be applied to the finish of both large and micro-scale materials [ 16 , 76 , 77 ]. These non-conventional finishing processes, including cylindrical MAF, plane MAF, internal MAF, MRF, and CMRF, are described in the following sections.…”

Influence of Process Parameters and Initial Surface on Magnetic Abrasive Finishing of Flat Surfaces on CNC Machine Tools

“…Magnetic abrasive finishing is used in different kinematic variations for machining flat surfaces [1][2][3][4][5][6][7][8][9][10][11], shafts [12][13][14], thin-walled tubes [15][16][17][18][19], wires [20,21], cutting tools [22][23][24] and freeform surfaces [25][26][27]. However, this usually requires separate equipment, which increases the time and costs involved.…”
