Grinding is a material removal and surface generation process used to shape and finish components made of metals and other materials. The precision and surface finish obtained through grinding can be up to ten times better than with either turning or milling. Grinding employs an abrasive product, usually a rotating wheel brought into
15/11/1997#0183;#32;2. Design of the grinding machine tool The ultraprecision machine tool is composed of highaccuracy machine elements. The spindle has a high rotational accuracy and the feed mechanism must have high stiffness and low frictional resistance for smooth feed motion. Also, the structural material must have high stiffness and high damping.
a spindle design solution and an analysis of its deflections, depending on its ejection, and the size of the passive forces. Keywords: grinding machine, spindle, design 1. INTRODUCTION
For the design of the grinder it is therefore appropriate to use the cursory fixed grinding wheels, located on the spindle. The spindle is in its length supported by a pair of supports, and it is attached to a moving carriage which ensures feed during the grinding. The layout of the grinding machine is shown in Fig. 1.
The motor is mounted adjacent to the spindle, and the torque is transmitted to the spindle shaft by means of a cogged or Vbelt. The power, torque and speed of the spindle will therefore depend upon the characteristics of the driving motor, and the belt ratio used between the motor and the spindle.
the reliability of a spindle. In nearly all cases this can be simply done by replacing the bearing and no changes being necessary to the actual spindle design. Some sections include a useful tip like the one shown below, these tips are based on many years of experience and can be particularly useful for newcomers to the spindle repair business
NSK Industries Spindle of Grinding Machine: Within NSK''s own precision plant, a grinding machine was experiencing raceway form errors. After numerous attempts to correct the form error, the fault remains unidentified. Initial readings were taken using NSK Condition Monitoring Service prior to replacing the bearing.
Grinding and polishing is the final stage in the sample preparation process and consists of several steps. Each step uses finer abrasive than the previous one, the ultimate goal being to produce a deformationfree, scratchfree and highly reflective sample surface. Electrolytic Polisher amp; Etcher.
