In machining, reaming hole machining is often encountered. Because the number of teeth of the reamer is more, the guidance performance is good, the diameter of the heart is large, the rigidity of the tool is good, the processing margin is less, the thickness of the chip is thinner, can obtain higher dimensional accuracy. But there are some problems in practice, and here are some solutions to them.
Here is the content list:
●How do I resolve the reamer's reamed inner holes that are not round?
●How to resolve the reamer's reamed inner holes that are not round?
●How can I extend the life of the reamer?
The reamer with insufficient rigidity can use the reamer with unequal pitch, and the mounting of the reamer should use rigid joints to increase the main angle, select a qualified reamer to control the hole position tolerance of the pre-processing process, and adopt the reamer with an unequal pitch reamer, using a longer, more precise guide sleeve, select qualified blanks, use iso-tooth range reamer hinging more precise holes, the machine tool spindle clearance should be adjusted, the guide sleeve should be required to match the gap is higher, the use of appropriate clamping methods to reduce clamping force.
Can reduce the cutting speed, according to the processing material to choose cutting fluid, appropriately reduce the main angle, the correct edge grinding reaming blade, appropriate reduction of reaming hole margin, improve the accuracy and quality of the front bottom hole position of the reaming hole or increase the reamer margin, select qualified reamer, grinding edge width; reduce the number of reamer teeth according to the specific situation, increase the space of the debris tank or use the reamer with edge inclination to make the discharge of chips smooth; for the reamer that has been hit, apply a special oil stone to repair the injured reamer, or replace the reamer, and trim the reamer with oil stone to pass, using a reamer with a front angle of 5 to 10 degrees.
The reamer material is not suitable, the reamer burns during the edge grinding, and the cutting fluid selection is not suitable will shorten the life of the reamer. Depending on the processing material, the reamer material can be selected using a carbide reamer or coated reamer, strictly control the amount of cutting edge grinding to avoid burns, often according to the processing material correctly select cutting fluid, often remove the chip in the chip tank, with sufficient pressure cutting fluid, after semen or grinding to meet the requirements.
Precision reamers are designed for high-precision small hole expansion of previously formed holes and for keeping the edges smooth. Hejian Hengji Bit Manufacture Co., Ltd has developed a variety of reamers, in front of the factory carried out many tests to ensure quality.
