Vertical Honing Machine

4.1Honing bar box:

It adopts a closed box, and the 7.5kW frequency conversion motor drives the main shaft to rotate through the direct connection to drive the gear of the spindle box. The speed is step less, and the speed range is 5-250 r/min. The output torque of the main shaft is large, and the transmission is stable. A hydraulic cylinder or a servo motor is installed at the rear end of the main shaft to control the expansion and contraction of the tool. Through the axial movement of the driving mandrel, the radial expansion of the honing bar is driven by the inner conical mandrel of the honing head, so as to realize the adjustment of the size of the tool.

4.2 Carriage rapid moving system:

The carriage is installed on the linear guide rail, and the servo motor drives the ball screw through the reducer to drive the carriage to reciprocate. The reciprocating speed is 1-25 m/min, which meets the speed requirement of the machining aperture.

4.3 Cooling system:

The cooling system is filtered by a sedimentation-magnetic separator, and a paper belt filter can be added. The filtration precision is less than 30μm.

4.4 Workpiece clamping:

According to the actual conditions such as the shape of the parts, or according to the customer’s requirements, design automatic or manual fixtures, the fixtures are installed on the worktable with T-slots, and the parts to be processed for the first time need to be calibrated with the spindle center , the same part processing does not need to calibrate the alignment later.

4.5 Bed part:

 The machine tool is composed of a machine tool base, a column, and a fully protective sheet metal cover of the machine tool. There are movable doors on both sides of the machine tool to facilitate the hoisting of large parts. The operation position protective door can be moved on both sides to facilitate various clamping and operations. Require.

4.6 Electrical part: 

This machine tool adopts Siemens PLC control system in the honing process, which can realize automatic cycle control, the reciprocating speed is displayed on the panel, the reversing is stable, and the speed adjustment is convenient; at the same time, it can realize the size control of the honing head, so as to ensure the machining accuracy and size of the hole. consistency. The dimensional accuracy of the aperture is guaranteed and the labor intensity is reduced. There is a pressure regulating switch on the panel, which can easily adjust the honing pressure. The display screen can show the machine status such as spindle load, honing head position, honing time, and the shape of the machined hole at all times, and the parameter setting is quick and convenient.
