Lathe ZMM drained. Domains. Multi-start thread cutting

Websites, like flowers and cars, need care. If a site is launched and no one cares about it, then sooner or later it will stop working. But a website is not just text and pictures, it is the face of a company on the Internet, a sales channel. And when the site stops working, at first glance nothing happens, but over time there are fewer calls and clients. Those who visit your site will think that the company has closed - after all, its site no longer works. Those who searched for your company on the Internet will not be able to find it - again, the site does not work. Only competitors will be happy.

“We ordered a website from our local web studio, paid for everything, and now our site is gone. The web studio doesn’t answer phones, doesn’t answer letters, we came to their office - it turns out they moved out a long time ago.” Unfortunately, this is a typical situation. It still happens "a programmer was working on our site, he quit with all the passwords", “The company went through a reorganization, while they were sorting out the cases, they lost the website” and of course “I don’t understand anything about these Internets of yours, help me fix our site.”

“My company, YugPodzemCommunications LLC, is engaged in the laying and maintenance of external pipelines, the website was made for us by local Krasnodar developers back in 2008 and everything was fine - they monitored it, updated it, it was easy to find in Yandex. But I don’t know what happened - It’s either a crisis, or they’re tired of doing their job - an employee comes up to me and says - Andrey Yuryevich, our website is not working, the second client has already told the programmers about this today - and there “the phone number is not available.” everywhere, on official cars. What to do. I called my friends - they gave me the contact of the St. Petersburg guys, they fixed the site for me and are managing it. Thank you, A.Yu.- client website ugpc.ru

STEPS TO RESTORE THE SITE:

Call us at 8-800-333-16-58 or write to e-mail [email protected] to clarify the cost and timing of work. Restoring a domain and website is not cheap, but the company’s reputational losses and the costs of creating a new website are much higher than the cost of restoration work. The basic period for domain re-registration is 3 business days, site restoration is 5 business days.

Fill out a form for a domain for an individual (download the form) or send the details of your legal entity. For work whose cost is from 7,000 rubles. it is possible to conclude an agreement (download the agreement). You pay for the work.

What is a domain:

A domain is the address of a website on the Internet, a set of letters and numbers, like a telephone number. Our website address is dra.ru, VKontakte address is vk.com, Yandex address is yandex.ru. Domains are registered and maintained by domain registrars. Every website on the Internet has its own domain. Your site does the same, only now the domain is not working and needs to be restored.

Who is the domain registered to:

On individual or at entity at your request. If you are an individual entrepreneur, then from the point of view of the legal status of domains, the domain is registered in your name as an individual. For some domain registrars it is possible to register for non-residents Russian Federation(foreign individuals and companies).

Who owns the domain:

A domain is not an object of property law (like an apartment or a car), so from a legal point of view it does not have an owner. A domain is an entry in the registry of a domain registrar that has an Administrator, who is essentially the owner (manages the domain, renews it, or can transfer the domain to another administrator). You can check who is the domain administrator via Whois service at the registrar, for example, in Axelname - if in the Org: field it says KreoBits or CreoBits - then the domain is with us, if Private person - then the domain is with a private person (in accordance with Federal Law 152 on personal data, the registrar does not have the right to indicate the full name in public data and therefore “Private person” is written for all individuals).

We create an account (agreement) with an accredited domain registrar based on your personal application form or the details of a legal entity and carry out the registration of the domain in your name. We create a new hosting for the site and rebuild the site pages with text and pictures on modern system MODx site management. As a result, we get a fully working website that looks and is filled in the same way as the website you had before. We give you passwords for the domain, site editor and hosting.

What is hosting:

In order for a website to be accessible via the Internet, it must be placed on an Internet server (specialized computer). This service is called " hosting"(from English) hosting). Technically, a website is a set of files, it is hosted on a hosting and becomes accessible from any device connected to the Internet. If the hosting is good, then the site is always available, works quickly and does not break. If the hosting is bad, the site will work slowly and intermittently. We host restored sites on equipment in the Selectel data center (Moscow), this is one of the best hosting providers in the Russian Federation.

What is MODx:

MODx is a content management system from English. Content Management System (CMS). It is needed for the site to work, drawing an analogy - just as Windows is a system for managing a computer, and Android is for a smartphone and tablet, so MODx is the same thing, only for the site. But unlike Windows and Android, there are hundreds of site management systems for websites that differ in purpose and complexity, the most common of which are 1C-Bitrix, UMI.CMS, Wordpress, Joomla and MODx. the main task MODx, like any other CMS, provides the operation of the site and convenient tools for editing it by the programmer and editor (for example, the manager of your organization). CMS are paid and free, MODx is free, all management is in Russian.

Brief description of the main components of the CU-500 (SU-500) machine

Spindle speed selection

Universal lathes CU400 are equipped with 21 forward and 11 reverse high-speed spindle speed stages. Speed ​​steps for each specific model machine are shown in Figures 4-3, 4-4, 4-5 and 4-6.

The choice of speed level for all models is made using handles 24, 25 and 26.

The disk, in Fig. 4-3 and Fig. 4-5, located on the front side of the gearbox and controlled by handle 24 in Fig. 4-1, has four fixed positions. The sector of the disk in which the required revolutions are located is set to the left or right vertical line depending on where the fixed position of the disk is.

Using handle 26, Fig. 4-2, which has two fixed positions, the pointer is set in the direction of the corresponding sector.

Note: For the CU500MT model, the sector with the required speed in Fig. 4-4 is positioned against the arrow on the plate.

The hub, Fig. 4-6, controlled by handle 25, Fig. 4-1, is equipped with three color indicators (green, red and blue) Fig. 4-6. The background color of the required reverse stage is set opposite the arrow on the plate.

The spindle is started and stopped for rotation in the forward or reverse direction using handle 22 in Fig. 4-1.

Warning: The spindle rotation speed can be changed ONLY after the spindle has stopped. Any attempt to change speed while the spindle is rotating risks serious damage to the gearbox and voids the warranty.

Feed drive

The feed mechanism of the machine for feeding and threading includes:

• Mechanism for normal and increased pitch, left and right threads: it is located in the gearbox, pos. 3, Fig. 4.2, and its adjustment is made using handles – pos. 23 and 18;
• Guitar, Fig. 4-2 pos. 11: its adjustment is made by moving the lowest gear block, according to Fig. 4-7; 4-8; 4-9 and 4-10 or a plate mounted on the front of the gearbox;
• Gearbox position 4 Fig. 4.1: it is adjusted using handles 28 and 29 for thread pitch or feed and handle 30 for thread type and feed;
• Caliper box: automatic movement of caliper feeds is carried out by the drive shaft and caliper mechanism. Turning on and off the longitudinal or transverse feed of the caliper is done with handle 32 Fig. 4-1. The direction in which the handle moves corresponds to the direction in which the caliper moves.

The movement of the caliper when cutting threads is carried out through the lead screw and the split nut of the caliper box. The split nut is engaged to the drive screw using handle 31 in Fig. 4-1.

Between the handle for turning on the automatic feeds and the handle for engaging the split nut, protection is provided that ensures that only one of them is turned on.

The caliper is controlled with the nut engaged through handles 22 in Fig. 4-1.

In addition to the feed movement, the caliper is equipped with a high-speed device with a separate electric motor.

The rapid movement of the caliper is activated by installing handle 32 in Fig. 4-1 on automatic feeding in the desired direction of movement and pressing button 41 Fig. 4-2 to turn on the electric motor. The caliper box is equipped with an overrunning clutch, which ensures that the caliper is engaged at high speed both when the feed box is turned off and on.

Setting up a thread cutting machine

The machine can be configured to cut metric, imperial, modular and pitch threads as indicated on the machine's nameplate.

Procedure:

• Set the revolutions and turnover girth using knobs 24, 25 and 26 in Fig. 4-1 and according to the thread plate;
• Using handle 23, Fig. 4-2, set the mechanism to normal or increased pitch;
• Handle 18, fig. 4-2 set the direction (left or right thread);

• Set the type of thread using handle 30, Fig. 4-1;
• Using handle 31, Fig. 4-1, engage the split nut to the screw;

In addition to the indicated thread, the table on the front plate also shows three additional threads, which are adjusted in the manner described above.

In addition to the indicated thread, the table on the faceplate also shows three additional threads, the settings of which differ from those described above in the text. (Follow additional label instructions.)

Multi-start thread cutting

Procedure:

• Set up the machine for threading with a thread pitch multiplied by the number of strokes, according to paragraph 4.6;
• Carry out cutting of the first thread stroke;
• Using the belt washer, manually rotate the spindle so that the number 0 from plate 44, Fig. 4-2 is opposite the pointer;
• Place handle 18, Fig. 4-2 in the neutral position;
• Rotate the spindle in the direction indicated on the plate until the number corresponding to the number of thread strokes is opposite the pointer;
• Turn on handle 18 Fig. 4-2;
• Cut the next thread, etc. by repeating steps from step 3 to step 7 until all the strokes of the desired thread are cut.

Warning: When cutting multi-pass threads, do not change the cutting speed.
