DIP lathe 300 the same, as well as its newer modification 1M63, well known to specialists, whose activities are related to the need to perform metal-cutting operations. Machines of this model, differing in rather wide functionality, successfully used to perform various cutting operations as with black, and with non-ferrous metals.
DIP lathe 300
Machine of turning and screw-cutting group DIP 300, as well as a similar DIP model 200, began to be produced by domestic industry in the 30s of last century and for several decades was successfully used by almost all machine-building plants. Such machines are most widespread at enterprises, producing metal products and single small series.
DIP machine 300, as well as its more advanced version 1M63, has a high reliability of the spindle and carriage, due to the peculiarities of its design. With this machine you can perform the following types of metalworking operations, as turning cones, boring, threading of various types (metric, inches, pitches, modular), drilling, turning of internal and external surfaces.

To work at the DIP 300 use cutters made of high-speed steel, differ in the increased durability. Such cutters are optimally suitable for that, to process details by cutting as black, and non-ferrous metals. Depending on the characteristics of the material being processed, a cutter with soldered carbide inserts can be used as a tool..
An important feature of the machines of this series is that, that the upper sled of their caliper can be moved, this makes it possible to process long conical parts on such equipment. The caliper itself is driven by a separate electric motor, which makes it possible to move it in the longitudinal and transverse direction at high speed. It should be noted, that almost all equipment of this series has such a possibility (in particular, did not have its popular lathe DIP 200), which significantly increased the processing time of parts.
Of the main characteristics of this model of lathe should be noted the following:
As can be seen from the technical characteristics of this machine, it is far superior in its capabilities and technical equipment to many of its counterparts, in particular the equipment of the popular DIP model 200.

High popularity of machines of this model, does not decrease for several decades, due to their advantages. These include the following features.
General view of the DIP lathe 300 1M63
The machine has a two-axle gearbox with a closed structure, which is more reliable and convenient in operation in comparison with boxes, equipped with special guitars (such boxes, in particular, were installed on DIP models popular at the time 200).
Adjustment of parameters of a transmission is carried out by means of special handles and change of gear wheels. This makes it possible to use a machine for cutting threads of any type: metric, inch, modular and drinking. With the help of a machine you can also cut a special and particularly precise thread (if you do not use the gearbox, and connect the lead screw directly - through a system of special wheels).
It is necessary to dwell on the characteristics of the caliper of this machine, which has a lot of advantages over equipment, which was installed on earlier models, in particular on DIP machines 200. DIP support 300 has a cross design and has the following characteristics.
Support DIP lathe 300
Longitudinal movement of the DIP machine caliper 300 carried out on the guides of the frame, and transverse - on the guides of the carriage. Which is convenient, such movements, if necessary, can be performed both by hand drive (slower), and with the help of a mechanical drive (in accelerated mode). The upper part of the caliper together with the cutter head placed on it can also be moved manually or by using a mechanical drive.
The gearbox of the machine of this model is attached to its main part - on the left side of the frame. All mechanisms of a box are driven by means of a shaft with a pulley, to which by means of a V-belt transmission and rotation from the electric motor is transferred. Step regulation of speeds in a box is carried out at the expense of use of gear wheels of various diameter, driven by a central shaft.

Using such a box allows you to get 24 speed, which are switched by connecting the gears in series, having different characteristics. In those cases, when the spindle needs to provide high speed gears are not used, rotation from the motor is transmitted directly. In this mode, the DIP 300 works with the minimum noise and with the maximum efficiency.
The technical capabilities of the gearbox allow a wide range (in 4-16 times) increase the pitch of the cut thread, as well as promptly change the direction of movement of the caliper. Changing the spindle speed is due to that, gears with different characteristics are engaged (diameter, number of teeth). Change gears, engaging, is performed by a special handle. Roller and ball bearings are used to facilitate the rotation of the gears on the shafts.
Hollow spindle supports, made of stainless steel, serving reliable bearings. At the same time in a forward support the two-row radial bearing of needle type is used, and in the back - the bearing of radial and persistent type. These bearings ensure easy rotation of the spindle and take the load, to which he is exposed.
The rotation is transmitted to the spindle by means of a plate friction clutch, which is actuated by a special handle. in addition, due to the use of such a clutch changes the direction and stops the rotation of the machine spindle.
