A variety of machine tools and related equipment are widely represented on the modern market. However, models that have been tested by time and have shown themselves on the positive side also remain popular. Such practical and reliable devices include the 6P13 milling machine. Along with high performance, it has an affordable cost. Consider the characteristics and features of this unit.
Short description
The equipment under consideration is used for processing billets of cast iron, steel and non-ferrous metal alloys. As the cutting part of the milling machine 6P13 is an end or end mill. The device passport contains information that the technical parameters of the device make it possible to operate it for milling horizontally vertical and inclined surfaces, including various frames, angles and grooves. It is possible to carry out work on complex trajectories.
Design features
The 6P13 vertical milling machine, the characteristics of which are given below, can be used to pass along a curved path, unlike many analogues. This is achieved due to the copier provided in the reader. At the same time, the design has a special electric indicator, the tip of which follows the template, determining the amount of movement of the table. A prepared copier is used as the basis.
Experts note that the specified equipment refers to multifunctional devices oriented to application in a single, small-scale or medium-sized production. It is worth paying attention that the marking of the device is made in accordance with the standards adopted in the USSR. The first letter indicates the unit belongs to the milling equipment, the first number indicates a subgroup, the second - the overall dimensions of the desktop. Based on this model, several variations have been released, differing in the dimensions of the base, the availability of software, engine power and the type of copying mechanism.
Technical Specifications of 6P13 Milling Machine
Below are the parameters of the equipment in question, according to the technical passport:
- total unit weight - 4.2 t;
- spindle location - 35-500 mm from the table surface;
- limit indicators of table movement vertically / transversely / longitudinally (with mechanical control) - 420/320/1000 mm;
- some models provide accelerated mechanical movement of the element;
- the maximum mass of the workpiece - 300 kg;
- milling material - alloy steel;
- force in the vertical / longitudinal / transverse direction - 8/20/12 kN;
- parameter of the maximum diameter of the working cutter - 200 mm;
- the feed box is equipped with a special clutch eliminating the possibility of overheating of the engine;
- spindle speed - 30-1600 rotations per minute;
- number of gears - 18 pieces;
- feed box moving speed - 12-1250 mm / min;
- the same vertical indicator - 8-415 mm / min;
- switching speeds - using a special handle;
- the electrical circuit of the milling machine 6P13 includes three electric motors;
- power scheme - supply of pulses to the cutting tip from the main engine (7.5 kW and additional analogues of 2.2 kW);
- cooling - liquid type, the refrigerant is supplied to the torch through pipelines using a pump.
Exploitation
The features of the specified equipment also include the rotation mechanism of the working head. It makes it possible to place the cutter at an angle of up to 45 degrees with respect to the plane of the table. It is this nuance that allows you to process inclined surfaces and holes.
The high drive power of the 6P13 milling machine, coupled with a good structural rigidity parameter, orient the equipment towards the ability to process parts made of reinforced metals. Such blanks are served using mills made of high speed steel or analogues of synthetic plate elements. The error in size and roughness is minimal, due to the features of the mechanism that provides maximum damping of vibration moments (GOST-8-77, category H).
The principle of operation of the vertical milling machine 6P13 is classic. The main rotation is the rotation of the cutter, and the additional is the table feed with the workpiece fixed on it. The operating mode in older models was calculated manually, set using the adjusting knobs and levers. In advanced modifications, CNC is used, which allows you to plan the workflow according to the template using the copy mechanism.
Device
The considered version is no longer in serial production. Nevertheless, finding spare parts is not difficult. Most modern analogues have similar units and assemblies that are interchangeable.
The main parts of the machine:
- The frame in the form of a bed.
- Swivel head.
- Speed box.
- Feed unit.
- Switching node.
- Console part.
- Mobile table with a sled.
- Electrical components and mechanisms.
The layout of the unit is also made in a standard style. On the skeleton there is a support with a slide that serves to vertically move the table. A grandma with a speed block and electrical equipment is mounted on it. The headstock aggregates with a spindle equipped with a device for turning the cutting tip with an angle of not more than 45 degrees. The spindle is in a static state during the workflow. The table is located directly above the head, equipped with feed units, electronic and mechanical configuration controls, as well as a slide for direct and lateral movement.
Finally
It should be noted that spare parts for the 6P13 milling machine, the characteristics of which are indicated above, can be manufactured directly on the considered technically sound equipment. This is due to the simplicity of design, high maintainability and the absence of special maintenance needs. In this regard, regardless of the appearance of the latest modifications, this model remains in demand at many enterprises and in small workshops.
