Selection of Rough Reference for Camshaft Grinding Wheel
The camshaft grinding wheel often selects the outer cylindrical surface of the blank supporting the journal and one of its side surfaces as the positioning reference. End face processing: domestic manufacturers use milling, and some foreign countries use grinding instead of milling.
How to use CBN grinding wheel and common problems
CBN grinding wheel abrasive is a new abrasive developed in modern times. Due to its high hardness and micro-crushed structure, it can achieve good efficiency for grinding high-hardness steel. However, there are several issues that need to be paid attention to in the use of CBN grinding wheels.
DFM Tip: Quickly design parts that are easy to CNC machining
There are many good tips to design your parts to make them easy to machine. In addition to CNC machining being one of the most popular manufacturing processes provided by Sujia, a part design that is ready for processing will also cost less than a part design that is not prepared or not well prepared.
Analysis of the cause of burnt workpiece by high-speed CBN grinding wheel
When the high-speed CBN grinding wheel grinds the workpiece, we often find that there will be burns on the surface of the workpiece, which is related to the high-speed operation of the CBN grinding wheel. The main types of workpiece burns are line-shaped or discontinuous line-shaped; there are two types of burns with black spots along the grinding direction of the grinding wheel.
Precautions for sheet metal processing design
Sheet metal processing is a non-additive and non-subtractive process. It starts with a flat material and maintains a constant material thickness throughout the part. In some cases, it is possible to selectively thicken the part area by welding multiple metal plates together, but this is a costly and uncommon practice.
CNC grinding machine CBN grinding wheel size selection characteristics
In order to obtain the ideal grinding speed in the grinding process of the CNC grinding machine, it is generally best to use a CBN grinding wheel close to the aperture, but when the diameter of the grinding wheel increases, the contact arc between the CBN grinding wheel and the workpiece also increases, resulting in grinding heat. increase, making chip evacuation and cooling more difficult.
Form of vitrified bond grinding wheel forming density
The forming density of vitrified bond grinding wheel refers to the mass of the abrasive body (wet and dry) per unit volume. It is the necessary data to calculate the quality of the material, the organization number, etc., and is an important factor to control the quality of the abrasive.
What are the forms of the forming density of vitrified bond grinding wheels?
Forming density of inorganic matter (green body) of vitrified bond grinding wheel: this density is only applicable to the formula table, it is purely a theoretical expression, which is based on the removal of flammable temporary binders (such as dextrin) from the weight of the grinding wheel blank, forming (inorganic) density obtained from porogen and water. When calculating the single weight of the grinding wheel, find the given inorganic molding density in the formula table, this density only includes the mass of the abrasive and the binder, and then add the mass of the temporary binder, water and pore-forming agent, and then calculate the actual single weight of the grinding wheel. Heavy.
