Figure 1 is a small-sized pentagonal squeezing reamer. Due to its small size, high precision, low surface roughness, sharpening is difficult. Due to the small outer diameter, it cannot be topped on the MQ6025 tool grinding machine. We designed a simple accessory - a five-sided shape by a template (
During the fertilization period, there are autumn leaves, spring germination, and chestnut fruit expansion period. Fertilizers are divided into organic fertilizers and inorganic fertilizers. The base fertilizer is mainly organic fertilizer. Commonly used organic fertilizers include green manure
Hydraulic manifolds are now widely used in hydraulic systems due to their compact size, ease of installation and low leakage. General-purpose standard integrated blocks, each integrated block can only be installed with only 2 to 3 hydraulic components, and some can only be installed with one hydrau
When our factory produces the chain wheel axle, the (?) connection process is completed on a simple special (?) tool. (?) With the (?) machine connection (see figure), the machine can be used to achieve automatic clamping, (?) connection, release action. The workpiece is placed on the positioning b
My machine repair company undertakes the large and medium-sized repair projects of various types of machine tools of the group company, among which the proportion of roll lathes is very large. There are three types of spindle bushings for general rolling lathes, namely: split sliding bearings, roll
Spherical workpieces are often encountered in machining and maintenance (Fig. 1). The measurement method of the radius of curvature is now described as follows. As shown in Fig. 2, the radius of the curvature circle of the table cover workpiece ABCD is: OB=OC=R, the thickness of the table ABCD is:
In order to increase the economic benefits of rice cultivation, it is necessary to adopt cultivation techniques for creating high-yield and high-quality rice. We study Japanese rice plantation, which is the technique of using rice bran as organic fertilizer and weeding. After several years of s
I. Introduction The inner groove surface of the variable lead screw is a spiral surface. As shown in Fig. 1a, the trajectory of any point on the cutting edge of the forming turning tool during machining is a spiral line which is expanded in a circumferential direction as a straight line, as shown
The CNC turning center CTX400E is a CNC machine tool that integrates the functions of trucking and milling produced by Germany (Dmaggi). Its powerful turning function, unique Y-axis and C-axis milling functions make the parts clamp and position times. Reduced, turning and milling parts are completed
Bacterial pesticides are biological pesticides with high insecticidal rate, no pollution to the environment, no poisoning of humans and animals, and no resistance to pests. However, the insecticidal action of bacterial pesticides is related to the number and activity of bacteria, and the meteor
