Lathe 1I611P: Specifications

Lathe 1I611P, processing on which it is possible to carry out as in the cartridge, and in the centers, already more 50 years successfully used in many industrial enterprises. The reasons for longevity and popularity of the equipment of this model were its reliability, versatility and high accuracy of processing.

Lathe IZh 1I611P

The purpose of the machine and features of its design

Though, that lathe of this model (the full abbreviation looks like this: IZH 1I611P), was developed in the 60s of last century, its technical capabilities still allow it to be used for various purposes, including responsible, metal work :

• lathes, performed in cam or collet cartridges, centers;
• milling;
• on grinding of external and internal surfaces;
• performed by the final tool, fixed in the drill chuck.

Characteristics of the lathe 1I611P allow to process on it preparations of cylindrical and conical forms, cut different types of threads: metric, inch, modular.

Versatility and reliability, which differs IZH 1I611P, determined by its design features.

• The cutter head is fixed on the backlash-free principle, which ensures its exceptional rigidity and, in accordance, high accuracy of processing.
• For threading (metric, inch and modular) with different parameters there is no need to change the gears in the guitar of the machine, which ensures the versatility of its gearbox.
• The design of the unit has a container of welded construction, in which the coolant tank and all electrical equipment are installed.
• Chip removal system, which is going to be a three-dimensional chip collection, has a well-thought-out design.

Controls of the machine 1I611P

• During machining on a 1I611P lathe, the operator can pre-select the spindle speed, which must be used at the next stage of processing (Preselective management).
• Apron 1I611P is equipped with a stop mechanism, which protects the gearbox from overload, and also allows you to perform turning operations using a rigid stop.
• Drive belts, by means of which the spindle unit is rotated, can be replaced without disassembly.
• Precise movement of the caliper in the transverse direction provides a special mechanism - the vernier.
• A mechanism can be mounted on the cross carriage of the caliper, which allows you to perform milling work.
• In those cases, when using a lead screw (threading), it is lubricated automatically.

• Cast iron, of which it is made ??bed 1I611P, has a special composition - chromium-nickel, and its guides are carefully ground and hardened by high frequency currents.
• Caliper feed management, for which one handle is responsible, carried out on the mnemonic principle: the direction of movement of this node coincides with that, in which direction the control knob is rejected.
• To protect the feed mechanism from overload, a special safety device is provided in its design.
• The design of this lathe is designed as follows, that there are no knots on its back, which need to be serviced. Thanks to such design feature it is possible to install the 1I611P machine even close to a wall.

The main characteristics of the device

Technical capabilities of the lathe 1I611P are as follows, that on it it is possible to carry out processing of details of the following diameter: to 25 cm - above the frame, to 12,5 cm - above the caliper. The maximum length of the workpiece, which can be processed on this equipment, is 50 cm. The spindle assembly of the unit can rotate in the forward direction with frequency 20-2000 about / min. The through hole in the spindle has a diameter 2,5 cm, and the landing cone corresponds to the Morse category 5.

Technical characteristics of the machine

Support 1I611P can make longitudinal and transverse feeds in the following intervals:

• longitudinal - 0,01-1,8 mm / about;
• transverse - 0,005-0,9 mm / about.

The carriage of the lathe of this model can move on the maximum distance 500 mm, the caliper does not have the ability to move quickly. 1І611П, according to the passport, has rather compact dimensions (length - 1770, width - 970 mm, height - 1300 mm), and is light in weight (1100 kg). Such geometric and weight characteristics allow to use this lathe for equipment of small workshops, multi-storey production facilities and even repair facilities of sea and river vessels.

The support and the carriage of the machine provide the increased accuracy of processing of details

The main purpose of the unit is to perform semi-finished and finished technological operations in the conditions of single and small-scale production.

We understand the design of the machine

In the design of the lathe 1I611P distinguish the following components.

front grandmother

In its center is a pulley, planted on the sleeve. This pulley, which rotates the spindle assembly, connects to the gearbox with 4 V-belts. From a receiving pulley by means of a gear coupling the spindle knot receives 12 speeds of rotation, will 12 it can be reported through busting. The gear coupling or search by means of the special handle is connected, which is located on the front of the body of the front headstock - on its right side. To exclude a possibility of simultaneous start in work of search and gear coupling, a locking mechanism is provided in the design of the front headstock. in addition, there is a mechanism in the design of the front headstock, which is responsible for increasing the pitch of the cut thread (8: 1), as well as the shaft, by means of which rotation is transferred to the guitar and further - to the gearbox.
