- Selection of Commonly Used Quenched And Tempered, Surface Quenched Gear SteelWe can divide the selection of steel for gearbox gears into the following categories to meet the usage needs under different working conditions:1. Non essential gears:For non essential gears in automobiles, tractors, and machine tools, due to their relatively small transmission loads, ordinary steel
- Gear Material1. Carbon (C)Carbon is one of the most important alloying elements in steel, which has a significant impact on the hardness and strength of steel. The carbon content of 18CrNiMo7-6 is in the range of 0.15-0.21%, providing good hardness and strength. The increase of carbon usually increases the hardn
- Why choose 18CrNiMo7-6 for rail train gears1. High strength and wear resistance18CrNiMo7-6 is widely used in the manufacturing of gears due to its high strength and wear resistance. Its main alloying elements such as chromium, molybdenum, and nickel form a hardened layer on the surface of the gear through appropriate heat treatment processes
- Terminology and definitions of gear blanks in reducersA reducer is a device that converts high-speed rotation of an input shaft into low-speed, high torque motion of an output shaft. Among various types of reducers, gear reducers are one of the most common types. The core component of a gear reducer is the gear, and the manufacturing process of the gea
- Common Surface Treatments for Metal Parts1. Electroplating: Commonly used metal parts are electroplated with zinc, nickel, chromium, copper, etc., to prevent corrosion, improve wear resistance, enhance aesthetics, etc.2. Anodizing: commonly used for surface treatment of aluminum alloys and is an essential process3. Blackening treatment: It
- Annealing process in heat treatment productionThe heat treatment process of heating a metal or alloy to an appropriate temperature, holding it for a certain period of time, and then slowly cooling it (usually with furnace cooling) is called annealing.The essence of annealing is to heat steel to austenitize and undergo pearlite transformation, a
- Annealing Process of Titanium Tube1、 The core principle of titanium tube annealing process is titanium tube annealing. As a key heat treatment process, its core lies in precisely controlling the heating temperature, time, and cooling rate to promote the transformation of the internal structure of titanium tubes, thereby optimizing t
- Introduction To Sandblasting And Shot BlastingSandblasting, as the name suggests, is the use of compressed air as power to spray abrasives (such as quartz sand, diamond sand, etc.) onto the surface of the workpiece at high speed. Through the impact and cutting effect of the abrasives, cleaning, deburring, surface roughness and other effects are
- Why is surface treatment necessary for machining parts?CNC machining processes (including milling and turning) often leave noticeable cutting marks, which can affect the surface quality of the machined parts. Although CNC machining can provide precision parts, these machined parts require surface treatment for various reasons.Why surface finishing CNC m
- Processing method of stainless steel 304There are various processing methods for stainless steel 304, including cutting, bending, welding, polishing, and drilling. Each processing method has its specific difficulties and precautions.1. CuttingCutting is a common processing method for size customization and shape cutting of stainless steel
