Matters needing attention in machining titanium alloy
During the process of machining titanium alloy, we should pay attention to the following points: 1. Because the elastic modulus of titanium alloy is small, the clamping deformation and forced deformation of workpiece are large, it will reduce the machining precision of the workpiece. Clamping force should not be too large when workpiece is installed, and auxiliary support can be added if necessary. 2. If the cutting fluid containing hydrogen is used, the hydrogen will be decomposed and released during the process of machining titanium alloy, resulting in hydroge
Cause and elimination method of surface vibration waviness in turning machining.
Cause and elimination method of surface vibration waviness in turning machining Vibration waviness is caused by various reasons in mechanical machining, which makes the machining surface of the lathe tool and the workpiece wavy.

Solution of oil mist filtration in mechanical machining
Solution of oil mist filtration in mechanical machining High efficiency machines with high cutting rates require a large amount of coolant for metal machining, and a large amount of metal dust and debris will be produced. Metal machining can also produce oil mist or coolant fog, which can cause risk to employees' health, and may cause CNC machine tools to malfunction. Small droplets may affect sensitive electronic components in the machine, resulting in sudden interruptions in operation. Modern industr

Why are some copper parts plated?
After machining copper parts, customers often require copper parts to be plated. Usually include: nickel plated, zinc plated, silver plated, tin plated, etc.. So, why are some copper parts plated? Electroplating can make the surface of copper parts adhere to a layer of metal film, so as to prevent the oxidation of copper parts, improve the wear resistance, conductivity, reflection, corrosion resistance (copper sulfate, etc.) and enhance the beauty and so on.
What is laser metal cutting and how does laser cutting metal work?
Laser cutting is the use of focused high power density laser beams to irradiate workpieces, cause the irradiated material to rapidly melt, vaporize, ablate, or reach the burning point, at the same time, the molten material is blown away by means of a high-speed coaxial beam, so as to achieve the workpiece cut. Laser cutting is one of the hot cutting methods. Although almost all metal materials have very high reflectivity at room temperature for infrared wave energy, but the CO2 laser, which emits 10.6um beam in far infrared band, has bee
What is plastic machining and what are the plastic machining methods?
Although plastic parts are mostly made by injection molding, in general, they must be machined to obtain accurate and economical parts, for example, plastic parts using mechanical machining methods to remove the gate, riser, flash and so on. For the plate, bar and other plastic parts, but also need to use cutting and punching and other mechanical machining methods for machining. Machining of plastic parts generally use metal machining equipment. However, due to the di
What is high manganese steel and what are the high manganese steel cutting characteristics?
High manganese steel refers to the steel with manganese content of about 11% to 18%. High manganese steel is a kind of wear resistant steel. High manganese steel treated by water toughening can obtain higher plasticity and impact toughness. High manganese steel has high wear resistance, although its hardness is only HB 210, but its yield point is lower, so it has higher plasticity and toughness. High manganese steel under external pressure and impact load, will have a large plastic deformation or severe hardening phenomenon, the steel is
Attention should be paid to silver plating in copper parts machining.
The metal structure of copper parts is more loose than that of rolled copper, and its appearance is rough and porous,in addition, the surface of copper parts is often left with a part of molding sand, paraffin wax and silicate substances. If the cleaning is not clean, it is often caused by partial plating, therefore, the surface cleaning of copper parts machining and strengthening the appropriate process steps are the key to solve the silver plating quality of copper parts. The general copper parts can be machined as follows:
Notes on silver plating of aluminium machined parts.
The silver plating of aluminum machined parts is much more difficult than that of ordinary copper parts, and the process is complicated. The main reason is that the performance of aluminum machined parts is different from that of other metals. Aluminum belongs to amphoteric metal and reacts with acid and base. If the pretreatment is a little improper, it will lead to surface corrosion. Moreover, aluminum machined parts are easy to produce oxide film in air or in solution. If the oxide film is not removed, it will affect the bonding str
What are the factors that affect machinability?
(1) Effect of room temperature hardness of workpiece material. Under normal circumstances, similar materials has high hardness, will has low machinability. When the material hardness is high, the contact length between the chip and the rake surface decreases, so the normal stress on the rake surface increases, and the friction heat concentrates on the smaller contact surface of the chip, which makes the cu

How to choose the position basis correctly in CNC machining?
When the workpiece is machined, the surface for determining the relative position of the workpiece to the machine tool and the tool is called the position basis. The position basis used in the initial process is the unprocessed surface of the rough, which called rough datum . The position basis used in subsequent process machining is the machined surface, which called fishing datum. 1.
