Brass C2600 C2680 C2700 Lathe Machining Parts Custom brass C5210 C5191 Anti-corrosion parts

Product Description:

High machining accuracy, stable machining quality; can carry out multi-coordinate linkage, can process parts with complex shapes; processing parts change, generally only need to change the CNC program, can improve work efficiency; machine itself, high precision, high rigidity, you can choose a favourable machining dosage, high productivity; high degree of automation of the machine tool, can reduce the labour intensity; high performance, low noise.

Commonly used mechanical metal cutting processing methods mainly include turning, milling, drilling, boring, planing, broaching, grinding and so on.

Turning

Definition: the workpiece rotation for the main movement, the turning tool for the feed movement of the cutting process.

Turning of the main motion for the rotary movement of the part, the tool moves in a straight line for the feed movement, especially suitable for processing rotary surface.

Turning process characteristics:

1. easy to ensure the positional accuracy of the workpiece surface (coaxiality requirements, perpendicularity requirements)

2. High production efficiency

3. Low production cost

4. Applicable to a wide range of materials for processing

The application of turning:

Single piece of small batch production, a variety of shafts, discs, sets of parts are mostly used to adapt to a wide range of horizontal lathes or CNC lathes to process. Large diameter and short length parts, more vertical lathe to process. Batch production of more complex shape, with internal holes and threads of small and medium-sized shafts, sets of parts, should be selected turret lathe processing.

Turning processing range:

Turning is to process the rotary body as the main processing purpose. In the lathe can be processed cylindrical, end face, taper, car forming surface, turning threads, winding springs and so on. In addition, it can also drill, ream, ream, tapping and so on. Turning machining accuracy is generally IT8-IT7, surface roughness of Ra6.3-1.6μm; fine turning, machining accuracy of up to IT6-IT5, roughness of up to Ra0.4-0.1μm. (Refer to different information results may be a little different)

Copper (Cuprum) is a metal element, but also a transition element, chemical symbol Cu, English copper, atomic number 29. pure copper is a soft metal, the surface just cut for the reddish-orange with a metallic luster, the monomers are purplish-red. Good ductility, thermal conductivity and high electrical conductivity, so in the cable and electrical and electronic components is the most commonly used materials, can also be used as building materials, can be composed of numerous kinds of alloys. Copper alloys have excellent mechanical properties and low electrical resistivity, the most important of which are bronze and brass. In addition, copper is a durable metal that can be recycled many times without loss of mechanical properties.

Brass
(1) ordinary brass: it is composed of copper and zinc alloy. When the zinc content is less than 39%, zinc can be dissolved in copper to form a single phase a, called single-phase brass, good plasticity, suitable for hot and cold pressurised processing. When the zinc content is greater than 39%, there is a single-phase copper-zinc-based b solid solution, called duplex brass, b so that the plasticity of small and tensile strength rise, only suitable for hot pressure processing. If you continue to increase the mass fraction of zinc, the tensile strength decreases, no value. Code with ‘H + number’, H indicates brass, the number indicates the mass fraction of copper. Such as H68 that the copper content of 68%, the zinc content of 32%, the brass, casting brass in the code before the word ‘Z’, such as ZH62, such as Zcuzn38 that the zinc content of 38%, the balance of the casting brass for the copper. H90, H80 single-phase, golden yellow, so there is a total of gold, known as plating, decorations, medals and so on. H68, H59 belongs to the duplex brass, widely used in electrical appliances on the structure, such as bolts, nuts, washers, springs and so on. Generally speaking, single-phase brass is used for cold deformation processing and two-phase brass is used for hot deformation processing.

(2) Special brass: in the ordinary brass by adding other alloying elements composed of multiple alloys known as brass. Frequently added elements are lead, tin, aluminium and so on, accordingly can be called lead brass, tin brass, aluminium brass. The purpose of adding alloying elements. The main purpose is to improve the tensile strength and processability. Code: for the ‘H + main plus element symbol (except zinc) + copper mass fraction + main plus element mass fraction + other elements mass fraction’ said. Such as HPb59-1 that the copper mass fraction of 59%, containing the main plus element lead mass fraction of 1%, the balance of zinc lead brass.

2. Bronze: In addition to brass and copper, the rest of the copper alloy collectively referred to as bronze, bronze can be divided into tin bronze and special bronze (i.e., Wuxi bronze) two categories. Designation: the method of expression for the ‘Q + the main plus element symbols and mass fraction + the mass fraction of other elements’ composed of. Casting products in the code before the word ‘Z’, such as: Qal7 said that the aluminium content of 7%, the rest of the copper aluminium bronze ZQsn10-1 said that the tin content of 10%, the content of other alloying elements of 1%, the remainder of the copper casting tin bronze.

Applications

1, divided into laser cutting, laser engraving, laser marking, glass (crystal) inside the carving and so on.
2, the process is through the laser engraving machine, laser marking machine, laser cutting machine and so on.

Advantages
1. Wide range: carbon dioxide laser can engrave and cut almost any non-metallic material. And it is inexpensive!
2. Safe and reliable: non-contact processing, will not cause mechanical compression or mechanical stress on the material. There is no ‘knife mark’, does not harm the surface of the processed parts; will not make the material deformation;
3. Precise and meticulous: processing accuracy can reach 0.02mm;
4. Save environmental protection: beam and spot diameter is small, generally less than 0.5mm; cutting and processing to save materials, safety and health;
5. Consistent results: to ensure that the same batch of processing results are completely consistent.
6. High-speed and fast: can be immediately based on the computer output drawings for high-speed engraving and cutting.
7. Low cost: not subject to the limitations of the number of processing, for small batch processing services, laser processing is cheaper.
