The amount of deformation.

Vertical  centre 1165 model Scraping process

The joint surface of the machine tool has been manually scraped. The machine tool has good precision and good accuracy retention. The lubricating oil on the scraping surface ensures the lubrication of the guide rail.

What is the classification of the machining accuracy of the Vertical Milling Centre 1165 Model?

CNC is an efficient automatic machine tool, which is composed of mechanical equipment and numerical control system, suitable for the processing of complex parts. CNC is currently one of the most widely produced and used CNC machine tools in the world. The CNC machining center has a strong comprehensive processing capability. More processing content can be completed after the workpiece is clamped once, and the processing accuracy is higher. For medium-to-difficult batch workpieces, its efficiency can reach 5-10 times that of ordinary equipment, especially it can be completed. Many processing that cannot be completed by ordinary equipment is more suitable for single processing or small batch, multi-variety production with complex appearance and high precision requirements.

Generally speaking, IT6 is an important matching index widely used in machining, which is divided according to the international precision tolerances. IT6 indicates that the mating surface has a high uniformity requirement, can ensure a fairly high mating performance, is stable and reliable in use, and the machining center can complete multiple processes such as drilling, milling, boring, expanding, reaming, and tapping.

Drilling is an important process of a machining center. Drilling is the basic method of machining holes. Generally, drilling is done on a drilling machine or a lathe. Some require higher precision, and it can also be done by a machining center. The drilling accuracy is not high, generally only 12.5~6.3μm, and the surface roughness of the workpiece is generally only 12.5~6.3μm, but the subsequent semi-finishing and finishing are generally completed by reaming and reaming.

Milling is the most important processing procedure of the machining center. It can be said that all the machining of the machining center is carried out with a milling cutter. Milling can be divided into up milling and down milling depending on the feed amount. It is an efficient and commonly used machining method to cut the workpiece with a rotary multi-blade tool. It is used to process various complicated curved surfaces such as planes and grooves, such as curved surface molds. The surface roughness of the workpiece processed with this tolerance precision is between 0.63 and 5 microns, and the precision tolerance of finishing milling can generally reach IT16-IT8 level.

Boring is usually used for inner diameter processing. A machining method that uses a tool to expand the aperture or trim the circumferential contour, usually used to convert semi-rough machining to finishing. For steel structural parts, the boring accuracy error level can reach IT9-IT7, and the surface roughness is 2.5~0.16 microns.

The existing machining technology has the highest requirements for grinding accuracy and the smallest tolerances. The punching machine, die-casting and other stations can be taught high, and mastering the precision tolerance of each process can make the CNC machining center give full play to its good characteristics. For different industries, the accuracy levels for different products are different. As practitioners and manufacturers, they must understand and pay attention to the actual needs of users' products, such as medical treatment, auto parts, etc., and the accuracy requirements of product accuracy and appearance parts. Both are higher.

Eight die-casting mould technical standards must be complied with Vertical Milling Centre 1165 Model

Die-casting mold is a method of casting liquid forging, a process completed on a special die-casting forging machine. Its basic technological process is: the metal liquid is firstly cast and filled into the cavity of the mold at low or high speed. Loose defects also make the internal structure of the blank reach the broken grains of the forged state. The comprehensive mechanical properties of the blank are significantly improved.

Die-casting molds are the three major elements of die-casting production, none of which can be dispensed with. The so-called die-casting process is the organic comprehensive use of these three elements, so that it can stably, rhythmically and efficiently produce qualified castings with good appearance, good internal quality, and dimensions that meet the requirements of the drawings or agreements, and even high-quality castings.

Die-casting mold is a very expensive special precision machine, requiring mold maintenance workers not only to have superb technology, fine work style, but also have a serious and responsible spirit. Mold maintenance workers should be familiar with the technical standards of die casting molds as follows:

Eight Standards

1. It is all about cleaning the metal filings and scales around the mold to reveal the true color of the mold.

2. With reference to the last die-casting product sent for repair together with the mold, carefully check the existing problems of the mold. Whether there is strain, mold sticking, crushing, falling off, whether small cores are bent or broken, whether the insertion and positioning of movable cores are not accurate, whether there are broken push rods or the length of push rods changes, and whether there are inserts that are not positioned correctly Check whether the fastening bolts are loose, etc. Mold expert WeChat: mujudaren Determine repair or replacement according to the damage.

3. Cavity collapse, cracks, falling blocks, etc. that cause minor strains on castings can be repaired locally by welding. Welding repairs should be performed in strict accordance with the welding repair process, otherwise a lot of mold life will be lost. The above failures are more serious or the mold is damaged in smaller molded parts.

4. Severe subsidence, cracks, falling blocks, etc. on the forming surface of larger forming parts can be repaired locally by welding. Welding repairs should be performed in strict accordance with the welding repair process, otherwise a lot of mold life will be lost. The above failures are more serious or the mold is damaged in smaller molded parts.

5. The sliding parts such as the core-pulling mechanism and guide device should be thoroughly cleaned, carefully inspected and repaired. Assemble after relubrication with high temperature grease.

6. If there is hydraulic core pulling, the hydraulic part and the mold should be repaired at the same time. Special attention should be paid to cleaning the hydraulic part to prevent pollution, otherwise it will pollute the entire hydraulic system of the die-casting machine.

7. When the mold breaks down or is damaged during the production process, the repair plan should be determined according to the specific situation. Complete repair as above if necessary.

8. For the mold that has been repaired and maintained, the molding surface, parting surface, and installation surface are treated with anti-rust treatment, closed, fixed, and placed on the backing plate according to the installation direction of the mold on the machine. Mold accessories are placed together with the mold.
