Hardware processing is to process raw materials (stainless steel, copper, aluminum, iron…) with lathes, milling machines, drilling machines, polishing and other machinery according to customer drawings or samples into a variety of non-standard products Parts, such as: screws, motor shafts, model car parts, fishing gear accessories, speaker enclosures, mobile power supply enclosures, etc. The processing of these hardware products is rarely the surface treatment of the product. Why is the surface of the processed product not handled as well by others. What kind of process do others go through? In view of this problem, let’s take a concrete look at what steps should be taken in the surface processing of a better product.

  • 1. Polishing: Overcoming defects, deburring and brightening the surface.
  • 2. Sandblasting: The purpose of precision metal processing aluminum surface treatment is to overcome and cover up some defects of aluminum alloy in the machining process and to meet some special requirements of customers for product appearance. There are glass sand, tungsten sand, etc., showing different feelings, similar to the rough texture of ground glass, and fine sand molds can also show high-end products.
  • 3. Electroplating: It is more common, and there is an electroplating process after polishing.
  • 4. Car pattern: It is a processing method for reprocessing after the mold is formed, and the pattern is processed by a lathe. Adults show very regular texture features.
  • 5. Rubbing pattern: It is called wire drawing, which is similar to the car pattern. They all form a smooth continuous pattern on the surface. The difference is that the car pattern is expressed as a ring pattern, and the rubbing pattern is a straight line pattern.
  • 6. Oxidation (coloring): There are two purposes for aluminum surface treatment and oxidation to enhance physical properties and achieve the purpose of coloring.

The characteristics of non-standard hardware processing

High precision is the most obvious advantage of Xiangjie Hardware’s non-standard processing. We have multiple precision CNC lathes; we specialize in the production and customization of various screws, nuts, mechanical parts, fixtures, medical equipment, non-standard parts, etc.; available Samples and drawings produce hardware, small-diameter stainless steel capillary processing, stainless steel capillary drawing, hardware products and various precision shaft products. We also have advanced multifunctional image measuring instruments, micrometer micrometers, depth gauges, vernier calipers, professional thread gauges, tool microscopes, roughness meters and other precision measuring equipment.

Hardware processing process:

  • 1. Familiar with the drawings of processing equipment and hardware parts: In order to be able to process the required precision hardware, you need to carefully check the hardware drawings before processing the precision hardware, and check the shape and size of the required precision hardware. Be familiar. In addition, you also need to be familiar with hardware production equipment.
  • 2. Cutting materials according to the hardware parts to be processed: cutting materials is cutting materials, which refers to selecting hardware materials of appropriate specifications according to the size and processing technology of the hardware parts to be processed.
  • 3. Machining precision hardware: processing precision hardware is to put the lowered materials into the processing equipment, and process the raw materials according to the size of the precision hardware.
  • 4. Surface treatment of hardware parts: The surface treatment of hardware parts is to polish, polish, spray or electroplate the surface of the processed precision hardware.

Classified according to the relative position of the spindle and the worktable

  • (1) Horizontal machining center: refers to the machining center with the spindle axis parallel to the worktable, which is mainly suitable for processing box parts.The horizontal machining center generally has an indexing turntable or a numerical control turntable, which can process all sides of the workpiece; it can also perform a joint movement of multiple coordinates in order to process complex spatial surfaces.
  • (2) Vertical machining center: refers to the machining center with the spindle axis perpendicular to the worktable. It is mainly suitable for processing complex parts such as plates, plates, molds and small shells. Vertical machining centers generally do not have a turntable and only perform top surface processing.In addition, there are compound machining centers with vertical and horizontal spindles, and vertical and horizontal adjustable machining centers with spindles that can be adjusted to horizontal or vertical axes. They can process workpieces on five sides.
  • (3) Universal machining center (also known as multi-axis linkage machining center): refers to a machining center that can control and change the angle between the machining spindle axis and the rotation axis of the worktable to complete complex space surface processing. It is suitable for the processing of impeller rotors, molds, cutting tools and other workpieces with complex spatial curved surfaces.

The form of multi-process centralized processing has been extended to other types of CNC machine tools, such as turning centers. It is equipped with multiple automatic tool changers on the CNC lathe, which can control more than three coordinates. In addition to turning, the spindle can be stopped or indexed. , And milling, drilling, reaming and tapping are performed by the rotation of the tool, which is suitable for processing complex rotating parts.

Advantages of CNC machining center After the workpiece is clamped on the machining center once, the digital control system can control the machine tool to automatically select and change tools according to different procedures, automatically change the spindle speed, feed, and the motion path of the tool relative to the workpiece, and other Auxiliary function to complete the processing of multiple processes on several surfaces of the workpiece in sequence. And there are a variety of tool change or tool selection functions, so that the production efficiency is greatly improved.

The CNC machining center reduces the time of workpiece clamping, measurement and machine tool adjustment due to the concentration of processes and automatic tool change, so that the cutting time of the machine tool can reach about 80% of the machine start time (normal machine tool is only 15-20%); At the same time, it also reduces the workpiece turnover, handling and storage time between processes, shortens the production cycle, and has obvious economic effects.

The CNC machining center is suitable for small and medium batch production with complex parts, high precision requirements, and frequent product replacement. The CNC machining center is the same as the CNC machine tool and the CNC milling machine. The machining center is also composed of computer numerical control system (CNC), servo system, mechanical body, hydraulic system and other parts. However, the machining center is not equivalent to the CNC milling machine. The biggest difference between the CNC machining center and the CNC milling machine is that the CNC machining center has the function of automatically changing tools. By installing tools for different purposes in the tool magazine, it can be automatically changed in one clamping. The tool device changes the machining tool on the spindle to realize multiple machining functions such as drilling, boring, reaming, tapping, and grooving.

The automatic tool changer of the CNC machining center tool magazine is composed of a tool magazine for storing tools and a tool change mechanism. There are many types of tool magazines, the common ones are disc type and chain type. The chain-knife stock has a larger capacity of tools. The tool change mechanism exchanges tools between the spindle of the machine tool and the tool magazine. The most common one is a manipulator; there are also those that directly exchange tools with the tool magazine by the spindle without a manipulator, which is called an armless tool changer. The machining center tool magazine is divided into two types: disc tool magazine and manipulator tool magazine.
