Protection measures implemented in 6T82Sh

To protect the operator working on the machine and people nearby from flying chips and coolant, the parts processing area is fenced with a protective device. It consists of curtains suspended on brackets. Moving the bracket in the loop makes it possible to change the position of the curtains in height, which is sometimes necessary when processing parts made of various types of metals. When installing and removing parts, the curtains are moved to the required angle to the left and right sides. There is a viewing window for viewing the treatment area. Without safety devices, operating the machine is strictly prohibited.

To ensure safe operation, the 6T82Sh also includes:

• feed stops (longitudinal, transverse, vertical);
• blocking of manual and mechanical feed (longitudinal, transverse, vertical);
• blocking separate supply switching;
• automatic intermittent longitudinal feed;
• spindle braking;
• overload protection.

Design of the 6T82Sh milling machine:

The main drive of the machine is distributed to a vertical processing head, which in turn has the ability to mill workpieces at angles. The vertical head can be rotated in the longitudinal and transverse directions. 6Т82Ш has a rigid cast iron frame, the weight of the machine is 3500 kg, which has a positive effect on its technical characteristics. The machine is cantilever, due to the operation of the engine, the work table has the ability to move vertically, and the spindle of the machine itself, also from its own electric motor, has a feed along the Z axis. The horizontal spindle of the machine has its own drive, respectively, both spindles are independent.

Basic technical data of the 6Т82Ш machine

The 6T82Sh cantilever milling machine is equipped with a main motion drive with a power of 7.5 kW. It allows for high-precision cutting at high spindle speeds ranging from 31.5 rpm to 1600 rpm. There are 18 such speeds in total for the horizontal spindle and 11 each for the overhead and rotary heads. The 6T82Sh machine implements a wide range of working equipment rotation speeds and table feeds. The number of the latter is 22. Due to all this, the operator working on the machine can easily select the optimal processing mode for a metal workpiece made of material of different densities, which allows for high-precision processing. It only remains to add that the maximum weight of the workpiece located in the center of the work table should not exceed 400 kg.

Operating principle of the 6T82Sh universal milling machine:

The vertical head can process workpieces at different angles; the head has a rotation around its axis and the ability to tilt. The machine bed is cast, made of hardened cast iron, this significantly increases the rigidity of the entire structure; heavy parts can be installed on the work table without compromising the processing accuracy. The rigid bed of the 6T82Sh machine can withstand heavy loads when processing complex materials. The 6T82Sh can be used to process all types of surfaces - vertical, horizontal, at various angles, made of steel, cast iron, non-ferrous metals and hard alloys. The machine has 2 spindles - horizontal and vertical. Thanks to the rotating head, the 6T82Sh universal machine can process gears, spiral planes, grooves, frames using various cutters (face, cylindrical, angular, shaped, spherical). Rotation is transmitted to the vertical head spindle through a separate motor and gear drive. In addition to a variety of milling work in horizontal and vertical planes, the widely-universal milling machine 6T82Sh performs all types of drilling work on metal, automatic drilling against a stop, boring holes, and cutting metric threads. Using a horizontal spindle, it can work as a horizontal machine; in addition, you can process side planes and die models. When milling workpieces whose size exceeds the permissible processing dimensions when installing a 6T82Sh milling machine on the desktop, the spindle head is mounted on a retractable trunk and rotates in planes if necessary. The advantages of the machine include the presence of both manual and automatic spindle feed modes. Typically, face and cylindrical cutters are installed in a 6T82Sh horizontal spindle. Both working spindles of the milling machine can simultaneously perform milling operations, since the drives operate independently from their own electric motors and gearboxes. The wide-universal milling machine 6Т82Ш can operate in an automatic cycle. When used as a horizontal machine, an earring is installed on the spindle for horizontal work on metal. The coolant system has its own motor, and lubrication is also supplied automatically. The tool is mechanically secured in the spindle. The drilling head rotates 90 degrees in both directions. As on modern machining milling centers, the braking clutch is electromagnetic. To expand the technological capabilities, you can install a dividing table on the 6T82SH work table; its dimensions vary depending on the size of the workpiece, universal heads, and a rotary vice. For safety reasons, when the feed is increased to prevent the tool from breaking, there is a safety clutch to prevent overloads. 6Т82Ш is reliable; if all standards are observed, the service life of the machine is 10 years. Additionally, the 8T82Sh machine can be equipped with a mechanism for reducing the working feed, this reduces processing time and increases the durability of the tool.
