There are five different types of cylindrical grinding: outside diameter (OD) grinding, inside diameter (ID) grinding, plunge grinding, creep feed grinding, and centerless grinding. The various grinding methods include straight cylindrical, taper, end face, and total shape grinding.

Diamond wheel for PCB Micro-drill

  Air conditioners, televisions, microwave ovens, induction cookers, cars, airplanes, electric cars, printers, fax machines, telephones and even toys with electricity are all common things in life using a component---PCB. What is PCB? PCB(Printed Circuit Board) is an important electronic component, the supporting body of electronic components, and the carrier of electrical connection of electronic components. Because it is made by electronic printing, it is called "printed" circuit board. Before the advent of the PCB, people achieved the same function through point-to-point winding. This unreliable connection method causes frequent failures at the wire connection and short-circuit when the wire insulation begins to age and crack. An important advancement is the development of wire-wound packaging. At each connection point, a small-sized wire is wound on the column to form a highly durable and easy-to-replace airtight connection. When the mainstream components of the electroni

How to reduce the influence of vibration during grinding

图片
  In production grinding operations, ripples on the surface of parts are potential clues to vibration problems in the machine or operating procedures. You will feel the influence of the ripples during inspection, or when there are still grinding or polishing steps in the later stage, you need to spend more time on removing the ripples. The surface of the workpiece shows ripples caused by vibration. The wavelength of the peak (distance from peak to peak) can provide clues to the cause of vibration For example, on a part machined on a surface grinder, the vibration frequency (cycles per minute) is equal to the working speed (inches per minute) divided by the distance (inches) between two consecutive tremor marks. Use this formula to find the vibration frequency. If it is the same as the rotation speed of the grinding wheel shaft, it indicates that the grinding wheel, the grinding wheel flange or the grinding wheel shaft itself may be the culprit. Changing the grinding wheel, tightening t

Why is the cutting tool deliberately "passivated"?

  Why is the cutting tool deliberately "passivated"? 2020.12.04 More SuperHard Products Co., Ltd 8 What is cutting tool passivation? By deburring, leveling and polishing the tool, the quality of the tool is improved and the service life is prolonged. After the tool is finely sharpened and before the coating, its name is not uniform at home and abroad. It is called "blade dull", "blade strengthening", "blade honing", "blade preparation" or "blade preparation". ER (Edge Radiusing) processing" and so on. Why is the cutting tool passivation necessary? The cutting edge of the tool after being sharpened by ordinary grinding wheel or diamond grinding wheel has microscopic gaps of different degrees (ie, tiny chipping and sawing). In the cutting process, the microscopic gap of the cutting edge of the tool is very easy to expand, which accelerates the wear and damage of the tool.
