Problem two: linear guide material linear guide a lot of chromium bearing steel, common such as GCr15, can also consider carburized bearing steel, such as G20CrMo. structural design should pay attention to the requirements of the quenching process, otherwise there will be cracking, deformation.
Question 3: What materials are generally used for grinding machine linear guide? Stainless steel ~ HIWIN is ~
What kind do you need ~ what do you need to meet the requirements of use? Hardness? Hardness? Working environment?
Question 4: What material is the slide of the guide made of? Hello, according to my understanding, the general heavy series is bearing steel, miniature series have stainless steel and bearing steel two kinds, also divided into brands, such as Japan's THK brand has bearing steel, stainless steel and aluminum material,,, Lu win electromechanical is very pleased to answer your questions, I hope to help you!
Problem 5: lathe guide rail problem lathe guide rail is generally what material The lathe guide rail material is generally cast iron. HT20-40 or HT25-47 casting, it is best to go through the open air natural aging for 1 to 2 years, but also can be artificial aging, machining and surface quenching treatment. (There are several kinds: high-frequency surface quenching; flame surface quenching; contact with electric surface quenching, etc.) quenching hardness up to HRC59-61 hope to adopt thank you.
Problem six: linear guide is what material to do the installation size is the same go is a national standard. Material are 55 steel. Only the same manufacturer's slider and guide can be interchanged. If it is an ordinary level of precision, who is cheap to buy who the quality can be used.
Question 7: What material is good for the guide? This depends on what you use on it. The guide is divided into grades.
Question 8: What is the material of the common lathe guide rail The material of the fixed guide rail should be harder, and the material of the motion guide rail should be softer.
Commonly used material combinations
Cast iron - surface hardened cast iron
Mutual Cast iron - hardened steel
Cast iron - paste plastic Cast iron
Heat treatment: high-frequency hardening, electric contact hardening.
For example, with gray iron HT250-300, but must be artificial aging treatment, the first to eliminate internal stress in the casting (due to the cast iron cooling inside and outside the speed is not the same), rough machining to see the use of the requirements to determine whether or not to quenching, if there is a requirement for the best is the ultra-audio quenching, and finally finishing, shovel with.
Question 9: What are the materials of the sliding guide 1. cast iron cast iron has good wear resistance, vibration resistance and processability. Commonly used types of cast iron are:
(1) gray cast iron is generally selected HT200, used for manual scraping, medium precision and low speed guide, hardness in the HB180 or more;
(2) gestation cast iron silicon-aluminum inoculant added to the iron and get, wear resistance is higher than the gray cast iron;
(3) alloy cast iron, including: the phosphorus content is higher than 0.3% of the high-phosphorus cast iron, wear resistance is higher than gestation cast iron. (3) alloy cast iron, including: phosphorus content higher than 0.3% of high phosphorus cast iron, wear resistance is higher than the pregnant cast iron more than double; phosphorus copper titanium cast iron and vanadium titanium cast iron, wear resistance is higher than the pregnant cast iron more than two times; a variety of rare earth alloys cast iron, has a high degree of wear resistance and mechanical properties;
Cast iron guide heat treatment methods, usually contact resistance quenching and high frequency induction quenching. Contact resistance quenching, hardened layer of 0.15 ~ 0.2mm, hardness up to HRC55. medium-high frequency induction quenching, hardened layer of 2 ~ 3mm, hardness up to HRC48 ~ 55, wear resistance can be increased two times, but in the full length of the guide rail quenching in turn is easy to produce deformation, the whole length of the quenching at the same time need the appropriate equipment.
2. Steel inlaid steel guide wear resistance can be increased by more than five times compared to cast iron. Commonly used steel are: 9Mn2V, CrWMn, GCr15, T8A, 45, 40Cr, etc. using surface quenching or overall hardening treatment, hardness of 52 ~ 58HRC; 20Cr, 20CrMnTi, 15, etc. carburizing quenching, carburizing quenching to 56 ~ 62HRC; 38CrMoAlA, etc. using nitriding treatment.
3. Non-ferrous metals commonly used non-ferrous metals are brass HPb59-l, tin bronze ZCuSn6Pb3Zn6, aluminum bronze ZQAl9-2 and zinc alloy ZZn-Al10-5, super-hard aluminum LC4, cast aluminum ZL106, etc., of which aluminum bronze is better.
4. Plastic mounted plastic guide has good abrasion resistance (but slightly lower than aluminum bronze), good vibration resistance, wide range of operating temperature (-200 ~ +260 ℃), strong resistance to tearing, dynamic and static coefficient of friction is low, the difference is small, can reduce the critical speed of low-speed movement, machinability and chemical stability of good parts, process is simple, low cost and so on. Currently in all kinds of machine tools in the dynamic guideway and graphics generator table guideway are applied. Plastic guideways are mostly paired with cast iron guideways that are not hardened.
Question 10: THK guide is what material Guide material points, stainless steel and carbon steel. Screws and guide rails with the material to do linear motion is mostly S55C steel. Bearing material is mainly divided into steel and stainless steel, in the specific material depends on your needs.
