the caliber of the tube is the first measuring tool used to check the mating parts. Caliber cannot be measured, and it is intended only for hit-testing the resulting size is within the specified range. the caliber of the tube was formerly the principal measuring tools in the engineering industry, but the emergence of CNC machines has made adjustments.

since the process of pulling the chips are formed as a rule in very difficult conditions, so the durability of the engine is influenced by the size and shape of the grooves for chip removal. Longitudinal section of the groove should be of such size that the groove could easily accommodate all of the resulting chips. If chip does not fit in the groove, it is pressed, which can lead to broken teeth and even to break the broach. The geometric parameters of the flute is determined by the length and thickness of the shear layer when pulling. Furthermore, the grooves should not be overly weaken the cross section of the broach.

depending on the nature of production, type of thread, size, dimensional accuracy and surface quality, as well as methods of their production all used threading tools can be divided into the following groups.
1. Tools with cutting blades, forming a thread with removal of chips. These include: nut cutters, combs and cutters, taps and threading round dies (chaser) and head, vortex high-speed heads, etc.

In this article we consider the purpose of grooving cutters and their applications. Of course, from the name of the mill is clear that it is intended primarily to produce a groove or a groove of such width and depth that you require. Next, we’ll look at that mill in detail.< / span>

the Main feature of the manual bending machine can be considered a direct part in the bending process of the material. This material can be wire, metal tubes, valve rods or metal sheets. Deserved such devices is widespread in various spheres of human activity. For example, manual machine designed for flexible reinforcement, can be applied in the process of construction of buildings, construction of diverse structures out of the reinforcing steel, manufacturing of products from reinforcing steel or laying foundations.< / span>
it is Worth noting that the manual machine is designed for bending reinforcement is performed from only the highest quality metals, which guarantees a very long service and provision of adequate security in the process of completing planned work. Speaking about the quality of the materials used in the production of such tools, the emphasis should be on the fact that whether it is a bending machine for profile, wire or sheet material, it is equipped with the gear mechanisms of high alloy steel. The implementation of these mechanisms of alloy steel gives you the opportunity to work with such kinds of metals like bronze, cast iron, steel of various grades and so on.
One of the important advantages possessed by bending manual machine is its absolutely light weight and minimum dimensions. This gives the opportunity to speed up your workflow, as there is opportunity to work with this tool in the most remote places. However, a manual machine for coiled rebar or wire has a fairly good ergonomics and appearance. All this makes working with him very pleasant and comfortable.
Especially relevant for such a tool for the business owner. Taking the decision to buy a bending machine, every private developer can greatly save on the order of rebar required configuration in specialized companies. An additional advantage of such devices for bending wire, rebar or metal sheets is the absolute simplicity of working with them, as well as minimal maintenance. It is only periodic cleaning and lubrication of gear mechanisms.
