FAQ

How to correctly install the tool in the machining center

1, the tool is long enough to expose the case as short as possible, as long as the clamping part. In addition, there is no damage to the barrel clamp.2, the main shaft of the tool is automatic tool change. Tool is installed on the knife according to requirements.3, the maximum weight of the tool, the maximum length, the maximum diameter requirements. Then is to control the tool's circular beat, the circular beat bad influence the machining accuracy but also damage the spindle.4, installation tool is not loose, confirm the tool in the handle is solid, the handle should pay attention to the rust, rust handle influences the machining accuracy of spindle hole wall damage.

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.

I know that there are two numbered Rules, one of which is T0101, T0202, T0303, T0404, etc.There is a T0101, T0102, T0103, T0104, such as the number, under the advice of the two numbersCan it be mixed? If you can, how to determine the knife mark?

Yes, don't get too caught up in it. The tool and knife mark are not necessarily linked, the tool number is fixed, the knife mark is alive.

In machining, the relationship between the speed and the feed rate is very important

Vc= PI nD/1000, Vc- line speed, n- speedVf=n*f Vf- feed speed n- f- feed per tooth

How to select NC milling cutter

In the process of the economical NC machine tool, the cutting, measuring and replacing of the tools are mostly manual and manual, and the auxiliary time is longer. General should follow the following principles: minimize the number of cutting tools; a tool clamping, should complete all processing steps which can be carried out; the machining tool should be used separately, even the same size of the tool; the first after milling drilling;; the first surface finishing after. For 2D contour machining; and where possible, should the ATC function as far as possible the use of CNC machine tools, in order to improve the production efficiency.

Turning steel pipe, what is good?

Feed from you for the 0.307 to judge, should not be a tool, but feed selection is too large, normally used coarse feed 0.3 is not small, not to mention the eccentric shaft, suggestions will feed appropriate small try.45# steel is generally used in the case of the YT15 is more suitable, YT5 poor wear resistance, YS8 brittle easy to jump knife. As for the speed depends mainly on the size of the workpiece diameter, if you use the cutting speed to measure, then the general rough car with 60 to 80 meters per minute, fine car with a 80 to 120 meters, the eccentric shaft should be appropriate to reduce the cutting speed.

What is the relative motion between the tool and the blank?

Hobbing? Gear manufacturers know

Cutting tool materials

Commonly used tool materials are divided into: tool steel (including carbon tool steel, alloy tool steel, high-speed steel), hard alloy, superhard cutting tool materials (including ceramics, diamond and cubic boron nitride, etc.)
