When clamping a straight shank milling cutter with a collet, if the chuck design is unreasonable, it is easy to drop the knife. In practice, we let the ratio of the two cones (see figure) of the chuck, the radial runout of the chuck is controlled at 10 ~ 20μm, so that the milling precision …
The conventional method of machining internal threads in our factory is turning. This method is not only inefficient, but also powerful, which brings a lot of unnecessary trouble to the operator. In particular, most of the small and medium-sized parts of the 330MW steam turbines that are curre…
The general forming turning tools are all machined on the tool grinding machine. Units that do not have such a tool grinding machine have to make the forming turning tools, and only grind them on the grinding wheel by hand. But hand-ground shaped turning tools. It is difficult to guarantee the…

Folded: Unfolded
The mass "five small" activities (small tricks, small innovations, small suggestions, small improvements, small inventions) are a new form created by the majority of workers and technical activists in Shenyang in the practice of long-term technical association activities. The “f…
When we check the tools, clamps, and inspection tools in the tool shop, we often encounter the problem of the inclination of the V-shaped groove to the bottom surface. Previously, we used the isosceles triangle pieces with the same angle of the apex angle and the V-shaped groove (Fig. 1). The …
This paper introduces the application of alkaline phenolic resin sand process, 3D solid modeling, computer simulation, metal pattern, etc. in the process of cooperating with GE Company of the United States to produce GE390-H gas turbine wheel generator set copper alloy casting bracket splint. T…
If you want to make metal parts more beautiful, the following methods can be used. The bamboo chopsticks 2 for eating are cut to a length of about 100 mm, and the cross section is round or square, and can be mounted on a common drill chuck (see figure). The surface of the workpiece 3 is evenly…
The design of the gauge should conform to the Taylor principle, but in practical applications, it is often difficult to fully implement the Taylor principle due to the most common manufacturing and use reasons. Therefore, the gauge form deviating from the Taylor principle can be used. The use …
The pressure plugging technology is an advanced technology for equipment maintenance developed since the 1970s. In the continuous production of modern industry, that is, the production process equipped with the latest technology, a high-level management method is implemented. Due to the influe…
The full runout of the engine cylinder crankshaft hole is an important parameter to reflect the machining quality of the cylinder crankshaft hole. The machining quality of the crankshaft hole directly affects the operating state of the engine. The defective crankshaft hole is one of the import…
GSK928TE lathe CNC system uses high-speed CPU and ultra-large-scale programmable gate array chip to form the control core. 320 × 240 dot matrix image LCD interface. Using international standard CNC language - ISO code to write part program, real μm level precision control, full screen e…
