Boring machine 2a450. A450 Kinematic diagram of a jig boring machine. Electrical diagram of the machine and the system of preliminary set of coordinates

The 2A450AF10 jig boring machine is designed for machining holes in conductors, fixtures and parts with precise axes and for light milling work. The presence of precise measuring instruments makes it possible to use the machine as a measuring machine.
Rotary tables are supplied with the machine for machining oblique holes and holes specified in the polar coordinate system.
Machine 2A450AF10 - single-column type, has a rectangular table with longitudinal and transverse movement. The adjusting movement of the spindle head is provided.
The working and accelerated movement of the table in the longitudinal and transverse directions is carried out electric drives with a wide range of regulation.
Precise setting of the table to a given coordinate is done manually, with a handwheel. The machine is equipped with precise optical measuring instruments.
devices that enable the operator to read on screens with a raster grid with an accuracy of 0.001 mm in two mutually perpendicular directions.
Optical correction devices available on the machine make it possible to increase the guaranteed accuracy of the machine.
Spindle rotation is driven by an adjustable electric motor direct current through a three-speed gearbox. Within each step, the spindle speeds are infinitely adjustable. Spindle feeds are also infinitely variable via a friction variator. There is a mechanism for automatic shutdown of the spindle feed at a given depth.
The machine is provided with mechanical table clamps in the longitudinal and transverse directions and manual clamping of the headstock.
The machine has a mechanism of preliminary set of coordinates.

The 2A450 jig boring machine is designed for machining holes with precise axes, the dimensions between which are specified in a rectangular coordinate system. On the machine, you can perform drilling, light (finishing) milling, marking and checking linear dimensions, in particular, center-to-center distances. The machine is equipped with optical screen reading devices that allow you to count the integer and fractional parts of the coordinate size.

The 2A450 machine is equipped with rotary tables, which makes it possible to process holes specified in the polar coordinate system, inclined and mutually perpendicular holes, and turning end planes. Under normal operating conditions, the machine ensures the accuracy of setting the center-to-center distances in a rectangular coordinate system - 0.004 mm. The machine is used for work in tool shops (processing of conductors and fixtures) and in production shops for precise processing of parts without special equipment.

Machine accuracy class A according to GOST 8-71.

Condition and equipment

Condition: mechanical condition is good, in non-working condition (displaying incorrect coordinate parameters on the rulers), partially disassembled, requires minor repairs (adjusting the coordinate rulers).

Complete set: incomplete - there is no box with equipment and tools, there are additional rotary tables 1 and 2-axis (tables are supplied for a fee).

Services: at the request of the customer, it is possible to carry out repairs and restore the parameters of the machine.
