Machine connection

Before connecting the machine to the power supply, connect the machine to the workshop grounding system 4 (Fig. 1)

The cable supply from the workshop electrical network to the input terminals of the machine is made through cover 5 on the top wall of the control station. The cross-section of the cable cores (wires) is determined by the rated current of the machine and the rated current of the input switch release indicated on plate 1.

ATTENTION! The machine must be reliably grounded in accordance with the rules and regulations.

IT IS PROHIBITED TO WORK ON THE MACHINE WITH THE CONTROL CABINET AND TERMINAL BOX OPEN. PREVENTIVE REPAIRS, INSPECTION AND CLEANING OF ELECTRICAL EQUIPMENT ARE TO BE PERFORMED ONLY WHEN THE POWER SUPPLY NETWORK IS DISCONNECTED.

The electrical resistance measured between the ground screw and any metal part of the machine that may become live as a result of insulation breakdown should not exceed 0.1 ohm.

Maintenance of the electrical equipment of the machine must be carried out by specialists in the electrical equipment of machine tools.

Remember that when the input switch is turned off, its upper terminals and the input terminal set are under mains voltage. DO NOT remove covers.

For inspection and adjustment of electrical equipment under voltage (with the cabinet door open), the circuit provides a release switch SA1 installed in the control cabinet. This switch must be used by qualified electricians.

Main types of work of the vertical milling machine 6T12:

— vertical milling of flat, stepped, curved surfaces

— roughing and finishing operations, the rigidity of the structure allows you to install heavy parts without loss of accuracy and productivity

- milling and drilling work at various angles, due to tilting the head

— processing of grooves, wheels, horizontal surfaces of parts

— drilling, boring work, with automatic tool feed, through drilling and against the stop

— thread cutting in semi-automatic mode, fine tuning of feed.

Kinematic diagram

The main task of the kinematic diagram is for the owner to understand how the main elements of the equipment interact and contact each other. The callouts include the number of gear teeth. The main movement is made possible by a flanged electric motor via an elastic coupling. The number of revolutions can be changed due to the movement of three gear blocks along special splined shafts.

The feeders are driven by a flanged electric motor mounted in the console. Thanks to two three-crown blocks and a movable gear, access to 18 different feeds is provided, which are transmitted to the console via a ball overload clutch.

Obtaining accelerated movements becomes possible when high-speed clutches are turned on, which rotates thanks to intermediate gears from an electric feed motor. The main element of the entire structure of the machine is the bed, on which other mechanisms and components are fixed. It is rigidly attached to the base using a set of pins.

How does the rotating head of the machine work?

The image above shows the current drawing of the rotary head, which is used in the 6T12 machine. It is centered in the annular recess located in the neck of the frame, secured with 4 bolts that fit into 1 different groove of the frame flange.

The spindle consists of a double-bearing shaft, which is integrated into the sliding sleeve. Adjusting the axial play comes down to the need to grind rings 4 and 3. Elimination of increased play in the front bearing becomes possible by tightening the nut and grinding ring 5. The owner is required to follow the correct maintenance procedure. To get rid of the radial play, the value of which is one hundredth of a millimeter, a grinding of approximately 0.12 millimeters is required.

Design and operating principle of the 6T12 vertical milling machine:

performs all types of milling and drilling work, the working dimensions of the table 320x1250mm allow you to reliably install and process a workpiece of the appropriate size, the milling machine allows you to process small and medium-sized workpieces up to 450mm in height. Thanks to the rigid design of the 6T12 vertical milling machine and a powerful electric motor, it is possible to produce parts with complex shapes, such as molds, cams, dies from various alloys. The vertical milling head of the 6T12 rotates 45 degrees, which allows you to process surfaces at an angle and a curved shape. Also, to process long workpieces, the spindle head itself moves on a retractable trunk. The console of the 6T12 vertical milling machine allows the work table to move vertically; if necessary, the operator can turn on, in addition to manual, automatic feed of the table in the vertical, transverse and longitudinal directions. You can expand the technological capabilities with the help of convenient devices - rotary tilting tables, dividing heads of different diameters, rotary vices, all equipment can be installed and fastened into T-shaped holes, of which there are 3 on the work table. Drawings of mounting and connecting dimensions, dimensions of the working space are sent upon request.
