Straight 1, ordinary linear optical axis (sf): Due to ordinary linear optical axis linear bearings in contact with the opposite point so the surface hardness of the ordinary linear optical axis of demanding, so materials and heat treatment method is very important. Material: suj2 (fairly) GB gcr15 hardness:. Hrc602 hardening depth: 0.8-3mm surface roughness: ra0.10m-ra0.35m straightness: 70um / 1000mm or less Shaft diameter tolerance g62, chrome linear optical axis (sfc) : chrome linear optical axis is based on ordinary linear optical axis of a layer of hard chrome plating, suitable for long rust prone environment or a bad environment this axis widely used in industrial machinery, exercise apparatus automatic sliding systems section. Axis: suj2 (fairly) GB gcr15 hardness:. Hrc602 hardening depth: 0.8-3mm surface roughness: ra0.10m-ra0.35m straightness material 3, chrome straight shaft (rsfc): chrome straight shaft due to its thick chrome plating can be directly used precision rod and some of the self-lubricating bearings fit. Because of its relatively modest hardness have applied in many fields. Material: 45 # or 40cr or 2cr13 hardness: hb220-260 hardening depth: 0.8-3mm Straightness: 0.15mm / 1000mm or less chrome thickness: 0.02-0.05mm4 linear axis, stainless steel linear shaft: stainless steel linear axis has a high resistance corrosion resistance, high strength and wear resistance in order to maintain its efficient operating performance. Therefore, it can be used in places prone to oxidation, such as water, chemicals, steam, water and so on. Material: sus404c, sus304 hardness: hrc602 hardening depth: 0.8-3mm surface roughness: ra0.10m-ra0.35m straightness 5, chrome-plated hollow shaft: chrome-plated hollow shaft due to the characteristics of its hollow structure, a large hollow shaft lessened the weight and simplify the structure, its interior is adapted to penetrate the measuring wires, compressed air, adding oil, or for the robot arm. The company also undertake all kinds of non linear optical axis (including diameter, tolerances, materials, etc.) are made and various shaft processing. High-frequency linear axis chrome plated piston rod, it is mainly used in mechanical systems, and is a linear reciprocating motion of the mechanical system, mainly played the role of support or drive, so it can be used as a machine with a guide rod or the top rods, etc., in the packaging, printing and dyeing machinery, etc., will be used in this rod. Dongguan Korea and Taiwan high-frequency mechanical transmission rod, it is the use of high-frequency quenching technology, and then to mirror polishing made, therefore hardness up to HRC58-62, and has better wear resistance and corrosion resistance. So, what is high-frequency quenching it? What is the principle? A: The high-frequency quenching, the workpiece is placed in the sensor, then passed through a high frequency alternating current, so that the induced current in the workpiece surface, so that the partial surface of the workpiece rapid warming, after Guangzhou linear axis for several seconds, then quickly cooled with water to the surface to achieve the appropriate hardness. High frequency piston rod during use, why is there beating phenomenon? A: The high frequency of the piston rod during use, there beating phenomenon reasons, mainly the following these points: (1) When machining Foshan linear axis, there is no good processing, processing quality, but off; (2) When positioning reference, there is no good location, or there are some errors; tolerances (3) does not select a good fitting; and (4) of the support ring wear and tear and so on. Guangzhou linear axis, Korea and Taiwan transmission machinery (certified), linear axis provided by the Dongguan City, Transmission Machinery Co., Ltd. of Korea and Taiwan.
