The gear lathe is a flower-shaped series with movable working parts. During machining, the workpiece rotates and moves axially, while the tool holder does not make any reverse motion. It belongs to the horizontal working structure: this type of lathe is suitable for small universal output lathes with a maximum workpiece diameter of 3mm. It is suitable for instruments produced in batches or in batches, tool companies and production workshops of instrument systems in the tool industry and military industry. It can open small modulus gear tools or other types of pin gear tools. It can also turn and filter shovel. The die size is .05-1.25mm, the tool pin is improved to Class A, and the machine tool precision meets the requirements of JET8489. The machine technology is the H-level precision machine tool specified in JET9871.[999], and the EDM lathe is suitable for batch production. It is specialized in small-module cutting tools of the factory and its workshop and production workshop. It is specialized in small-module hard metal gears, screws, etc., such as the basic type of machine tools and basic type. 4.2 Plate movable type 4.2.1 Gear cutting speed machine type as shown in Figure 1. The gear lathe is a mobile type series: when working, the parts rotate, the frame moves longitudinally and feeds horizontally, and the structure of the lathe is fully horizontal. The gear turning end of the machine needs to be medium and large, and the maximum diameter of the parts is 250mm, 400mm, and the speed is 500. This type is adopted. It is a universal type, which can be used for both turning and grinding, and can also be used for turning and grinding various patterns, such as bearing rods, 2

patterns, short screw rods, etc., and can process curved or dimensional shapes. This kind of universal tooth-cutting lathe with grids can add .1 precision to reach A number or AA number. It is a lathe for square parts with a diameter of 500mm. It is based on the tooth-cutting lathe for large parts with a diameter of 40mm. It adopts effective technology, expands the addition:. Straight, it is a light 500mm universal step lathe.
|The machine seat is in accordance with the provisions of F/8488.1, and the bed is B9B71-1999 standard V-level auxiliary machine description: 4.2.2 Semi-automatic gear lathe
The machine is more suitable for professional or batch production. Its factory is specially used for gear hobbing or flower hobbing with a module of 1-10mm, worm gear cutting and other points. The machine tool is a machine tool with high efficiency and commercial strength. It can process gears with a degree of degree. The main specifications of the machine tool are basically the same as the basic model.
This machine tool is based on the basic model by simplifying the transmission mechanism of the lathe, gathering the necessary transmission required by the production lathe, and considering strengthening the structural rigidity, and can The shovel blade nest is in an automatic cycle, and the feed cycle is automatically changed at the end of the cycle. The pre-selected precision link stem is automatically converted, and then the line pin ring is automatically added to the machine tool. The machine tool has a strong and strong frame. It is required that only the turning tool can be used to process the screw groove of the gear with a reading of 110mm or the flower chain insert tool, the worm gear cutting tool (single-blade surface eating tool has a module of 1-6mm, and the row comb-shaped tool can be used to process the standard straight groove of the gear hob with a reading of 1-4m, in order to achieve the purpose of improving the efficiency and reducing the manual labor intensity of the operator. 4.2.3 Electrolytic shovel gear turning|| tt||The machine is suitable for workshops or tool companies that need to add T modulus J8mm, improve the quality of alloy gears and other tools. The semi-tough alloy tool is used to extend the tool. In particular, this tool is suitable for rubber technology with poor flame retardancy, ductile iron without heat treatment, and non-ferrous metal gears.
Electromechanical machining is a process that uses the principle that metal can produce cationic decomposition in electrolysis to process the tool. This will cause less corrosion, and it is necessary to strengthen the protection of machine tools and human bodies. The machine tool can use diamond grinding wheels to semi-precisely align the workpiece. The machine tool has a T gear tool precision of B grade. The machine tool precision is the same as the basic model, 4. 2.4 Shovel milling machine tool
The machine tool is suitable for professional and large-scale production factories. It is used to scrape chain hob tooth shape. It can produce 9~16m chain hobs with disc-shaped cutters. It can easily adjust the module of 1B-25mm chain hobs. According to the requirements of customers, it has several types of main transmission components that meet the requirements. The machine tool has a strong structure and can be installed on a strong frame with a suitable cutting power head. In order to adapt to scraping processing, improve work efficiency and reduce labor intensity, the machine tool indexes and size are the same.
4.2.5 The lathe tool is suitable for professional and large-scale production factories. It can process disc-shaped cutters with a module efficiency of 1-16m. This machine tool is designed for the needs of the factory. It is simplified on the basis of the type and can produce a large diameter of 250mm. A short bed is selected to strengthen the structure; the pitch system and differential system including the large screw are removed to reduce the number of main transmission stages. In order to improve work efficiency and reduce labor intensity, this machine tool is a semi-automatic cycle bed. The stroke times are divided into two parts, one for the 1~8mm module and the other for the 1~1m module. The machine tool speed is basically the same as the basic machine tool.
