Q:Are all self locking knives controlled? The knife is small again?

According to this length, not

Q:CNC machine tools and cutting tools for the performance of the material requirements?

No special needs. Due to the general use of CNC machine tools for high efficiency and accuracy requirements, so try to use some of the more high-end tools.For example, selection of hard alloy steel processing (coated better), if the machining of hardened steel can also use the CBN (cubic boron nitride) blade, if you are aluminum processing can use PCD (directional crystal diamond tool).In order to reduce the uncertainty in the production, the use of non grinding machine tool. This can reduce the skeleton Ding Fen Feng Shui Fu amazing calcium scraping lettuce production factors, make the system more stable. Of course, you have to have enough high value-added products.

Q:What are the features of the CBN tool?

Because the CBN tool can be better than 0.4 m surface finish and maintain concentricity + 0.012mm, Dry Turning Hardened workpiece is usually a dirty alternative attractive strengthening grinding cooling scheme. Although CBN is a kind of tool material which is hard to be used in high speed and high speed milling, the range of application of ceramic and CBN is very much, so it is necessary to use cost benefit analysis to decide who can get the best result.

Q:What is the difference between insert and cutter

A big difference, the former is welded on the operation, trouble, after welding, grinding to open front, trouble, but the economic, however, if there is no special grinding tools like disposable almost, the latter is directly replaced by screws can, convenient blade welding blade than your price many, usually in 20 to 40 yuan a

Q:How to distinguish between YG tool and YT tool and YW tool appearance

This is the time to pay attention to the tool than when. There is a big gap between the brand.

Q:Kitchen knives what brand good?

Domestic: Eighteen sons, Zhang Xiaoquan, Deng Jiadao, Wang dazu.Europe: Zwilling, WMFJapan: ten days, To Jiro, Guan sun six, Guan Lian lian.

Q:If the hardness is too high to bring the tool too brittle, metal processing of high hardness of the tool will bring any benefits.

The high hardness of the tool and the tool wear resistance are closely related (such as the surface of the abrasive wear, generally after the knife surface wear as a tool wear standard), good wear resistance, tool life is high. The high hardness of the cutting tool material, from the material properties of the workpiece is increasing, the most basic concept is: the hardness of the tool must be higher than the hardness of the workpiece, otherwise not cut.A good performance of the tool, only with high hardness is obviously not enough, but also has excellent comprehensive performance, including mechanical properties, physical properties and chemical properties. The mechanical properties of the tool generally include: high hardness, high toughness, high strength, high hardness (hardness); physical properties including tool: thermal conductivity, thermal expansion coefficient; chemical performance refers to the low affinity chemical tool and workpiece. In addition to consider the cost of diamond tools and PCBN cutting tool performance is excellent, the cost is very expensive.

Q:What kind of cutting tool is better for steel casting

Problems in high speed machining of steel castings1, cast steel containing manganese, chromium, nickel caused by cutting tool wear, especially some large steel castings, a lot of cutting up a workpiece has been damaged, causing the trace of light is the impact of the efficiency and quality of processing, serious cause the scrap.2, there are sand, white and other casting defects or intermittent turning, easy to collapse knife, resulting in high cost of tool use

Q:What are the reasonable tool life?

In order to avoid the change of the tool in the process of the same surface, the durability should be higher, at least one knife should be completed.

Q:What is the most important influence on the cutting tool?

The roughness usually requires the feed rate to be determined, so the parameters of efficiency and economy should be calculated according to the requirements of the drawing
