(1) Cylindrical grinder: is an ordinary ...... [Read More]

1. Use a forming wheel to grind the punch, That is, the grinding wheel is trimmed into an inverted surface that is completely consistent with the surface of the workpiece, and then the workpiece is ground with the grinding wheel to obtain the desired shape. There are many ways to dress the gri...... [Read More]

Common defects in internal grinding are: The surface roughness is too bad, the surface is burnt, there are spiral marks and the shape error of the inner hole. The causes and elimination methods are briefly described as follows. 1. The surface roughness is too poor The main reason that affects...... [Read More]

Precision grinding can be divided into ordinary grinding wheel precision grinding and super-hard grinding wheel precision grinding according to the different grinding wheel abrasives used. Superabrasive grinding wheels currently mainly include diamond grinding wheels and cubic boron nitride gr...... [Read More]

Reasons for the gap of CNC machine tools: 1. There is a gap between the ball screw of the machine tool and the nut pair, which cannot be in close contact, resulting in shaft movement. 2. With the use of the machine tool, the wear gradually intensifies, resulting in gaps. Influence: 3. When the...... [Read More]

1. Edit and input of part program Before processing, you should first analyze and compile the processing technology and processing procedure of the workpiece, if the processing procedure of the workpiece is long or complicated. Do not program on the computer, but use a programming machine or c...... [Read More]

In order to give full play to the great economic benefits of CNC grinding machine, the following processing objects can be given priority. 1、 The parts put into operation repeatedly have better benefits. The preparation time of the process using NC grinder accounts for a high proportion. For ...... [Read More]

Current. Available for precision spindle system are dynamic bearing, rolling bearing, hydrostatic bearing, air bearing and magnetic bearing. 1. Magnetic bearing can only be used on very few professional machine tools due to its high cost, 2. The bearing capacity of air bearing is too low, so i...... [Read More]
