Abstract

The invention discloses a metal-based spherical diamond grinding wheel dressing device, which relates to a grinding wheel dressing device, and the aim of which is to solve the problem that the existing spherical grinding wheel dressing device is low in dressing accuracy, in particular that the existing spherical grinding wheel dressing device can not dress a spherical grinding wheel with small size. The lower end of the wheel spindle gripper of the invention which is provided with a wheel spindle is connected with a grinding wheel location driving system, and one end of an electrode spindle is provided with an electrode locking device, which is correspondingly to the wheel locking device in the wheel spindle. The spherical wheel of the invention has a high dressing accuracy (the surface figure is less than or equal to 0.5Mum), and can dress the diamond grinding wheel into a shape of a hemisphere, which is the unique advantage of the invention. Meanwhile, the metal-based spherical diamond grinding wheel dressing device has the advantages of realizing the eutopic dressing of the grinding wheel, taking out the dressing part (electrode installation part) separately to assemble on the machining tool to realize the eutopic dressing, decreasing the repeated clamping error of grinding wheel, and realizing the dressing metal-based spherical diamond grinding wheel with small size (Phi 3 to 10mm).

Description

Technical field [0001] The invention relates to a dressing device for grinding wheels. Background technique [0002] With the increasing development of science and technology, people have higher and higher requirements for the finishing accuracy of free-form surfaces, and most of these free-form surface parts are hard and brittle materials such as silicon carbide, optical crystal materials or ceramic materials. Therefore, it is an effective method to realize ultra-precision grinding and dressing with metal-based spherical diamond grinding wheels. However, many devices currently require small-diameter spherical grinding wheels for ultra-precision grinding and finishing due to their complex surface shapes, such as ultra-precision grinding of fused silica hemispherical resonator parts and optical microlens array parts. The dressing accuracy of the small-size spherical grinding wheel directly affects the machining accuracy of the parts. However, the existing spherical grinding wheel ...
