Grinding Features

Grinding is a method of cutting a workpiece with a grinding wheel as a cutting tool on a grinding machine. The features of this method are:

(1) Since the abrasive grains of the grinding wheel have high hardness and heat resistance, grinding can process materials with high hardness, such as hardened steel and cemented carbide.

(2) The characteristics of the grinding wheel and the grinding machine determine that the grinding process system can perform uniform micro-cutting, generally ap=0.001～0.005mm; the grinding speed is very high, generally up to v=30～50m/s; the grinding machine has good rigidity; using hydraulic transmission, so grinding can economically obtain high machining accuracy (IT6 ~ IT5) and small surface roughness (Ra = 0.8 ~ 0.2μm). Grinding is one of the main methods of finishing parts.

TransGrindTools manufacture wide range kinds of diamond grinding tools which can make your grinding work easier and more effective.

(3) The temperature of the grinding zone is very high due to severe friction. This will cause stress and deformation of the workpiece, and even cause burns on the surface of the workpiece. Therefore, a large amount of coolant must be injected during grinding to reduce the grinding temperature. Coolant also acts as chip evacuation and lubrication.

(4) The radial force during grinding is very large. This will cause elastic concessions of the machine-wheel-workpiece system, making the actual depth of cut less than the nominal depth of cut. Therefore, when the grinding is about to be completed, the smooth grinding should be carried out without feeding the tool to eliminate errors.

​​(5) After the abrasive grains are blunt, the grinding force also increases, causing the abrasive grains to break or fall off, re-exposing the sharp edge. This characteristic is called "self-sharpening". Self-sharpening enables normal grinding within a certain period of time, but after a certain working time, manual dressing should be carried out to avoid vibration, noise and damage to the surface quality of the workpiece caused by the increased grinding force.

What is epoxy terrazzo floor and epoxy terrazzo floor’s application and construction process

Image
Epoxy terrazzo floor , also called epoxy-based terrazzo floor, or organic terrazzo floor . It is suitable for shopping malls, exhibition halls, corridors, high-level entertainment venues, exposition halls, business clubs and other places that require beautiful and wear-resistant floors. A good-quality epoxy terrazzo floor needs to meet three conditions: Firstly, the surface is smooth and flat, without wear lines, blisters, cracks, and aggregates are evenly exposed, and the grid is firm; Secondly, the surface layer slope is designed reasonably and will not appear the situation of running water backflow; Thirdly, is that the heights of the skirting lines are the same, and the thickness of the constructed sample is uniform and there is no hollow. The construction process of epoxy resin terrazzo floor: 1. Basic cleaning In order to prolong the service life of the floor, make the flatness of the base layer meet the standard, and lay a good foundation for the subsequent coating const...

How to renovate the old cement floor

Image
  How to renovate the old cement floor: 1. Use a professional floor grinder , install the grinding disc , and grind the ground . Remove all the sand from the surface to reveal smooth and firm aggregates. 2. With the sealing curing agent, sprinkle it on the ground, let it fully absorb until it is saturated, which can increase the strength of the cement floor. 3. If the cracking of the cement floor is serious, first roughen the floor, and then rinse the floor with a water gun. 1. Construction joints shall not be left in the laying of the cement concrete surface. When the construction gap exceeds the allowable time, the joints should be treated. If the concrete floor is seriously sanded and ash, the water grinding machine should be installed with a diamond grinding block first. The purpose is to smooth the ground, remove the glue, paint, plain cement slurry and other attachments on the ground, and then assemble the diamond grinding block with a water grinder to grind the ground...

Several time matters of grinding a terrazzo

Image
Facing the weathering and abrasion of terrazzo, the most common and convenient method at home and abroad is to clean the dirt on the surface of the stone and apply a layer of wax. This method can play a certain protective role on the new terrazzo surface and delay the speed of natural weathering and abrasion. After a few years, the surface of the terrazzo has been weathered, and the renovation of the terrazzo can be resumed by simply grinding the ground at the price of 25/1 and 30/1 of the construction cost. The reason why cleaning and waxing is not a real stone floor treatment is that there is no real technical key to terrazzo treatment . The reason why the terrazzo is as bright and clear is mainly because a layer of glassy film is formed on the surface of the terrazzo after machining. This kind of ground needs to be completely solidified before wet grinding and polishing . Generally, the ambient temperature is 25 degrees and the humidity is 60% in a well-ventilated weather for...
