Do not cut off the connection of protective device when overhaul the electrical equipment of large water mill.

Electrical maintenance personnel should wear insulating gloves and rubber shoes to avoid electric accidents. And do not wear metal jewelry and other conductive articles that may lead to false electric shock.

Before overhauling the electrical equipment, pay attention to follow the instructions of the relevant warning plate, and use the appropriate three watt hour meter to confirm that the circuit is open circuit.

When overhauling the electrical equipment of the large gantry grinder, the main power switch must be cut off, and warning signs must be erected, so as to avoid the accidental injury caused by the reactivation of the large water mill without the knowledge of others.

When the motor is activated in the grinding machine, there may be sparks at the contact point of the electrical box, so the machine can not be used in dust, gas explosion and flammable places.

The electric box of large water mill is designed for the safe operation of the machine. No one is allowed to modify the structure and circuit design of the electric box without the authorization of our company.

The operator must be familiar with the position of emergency stop switch and main power activation switch of large water mill. In case of emergency, the machine can be stopped and the power can be cut off at the first time.

Process specification is one of the process documents that stipulate the machining process and operation method of parts. It is written into the process in accordance with the specified form for the machining of mechanical parts under the specific production conditions. The large-scale computer CNC machining center is a kind of CNC machining center with tool magazine and can automatically replace the tool, which can control the workpiece at a certain speed CNC machine tools for a variety of processing operations.

Large computer gong machining center is usually classified by the relative position of spindle and worktable, which is divided into horizontal, vertical and multi axis linkage machining center.

A horizontal machining center: it refers to the machining center with the spindle axis parallel to the workbench, which is mainly suitable for machining box parts.

B vertical machining center: it refers to the machining center with the spindle axis perpendicular to the worktable, which is mainly suitable for processing plate, plate, mold and small shell complex parts. C multi axis linkage machining center, also known as universal machining center, refers to the machining center that can control linkage change through the angle between the spindle axis and the rotary axis of the worktable to complete the machining of complex spatial surface. It is suitable for machining impeller rotor, mould, cutting tool and other workpieces with complex space surface.

After the machined parts are clamped once, the CNC system can control the machine tool to automatically select and replace the cutting tools according to different processes; automatically change the spindle speed of the machine tool, the feed rate of Dongguan CNC machining center, the movement path of the cutting tool relative to the workpiece and other auxiliary functions, and continuously carry out multiple processes such as drilling, countersinking, reaming, boring, tapping, milling, etc Processing.

Because the early CNC system of milling machine does not have the function of function calculation, it is difficult to work out the processing program of function equation curve directly with G code, and the CAD / CAM software (with lower version) usually does not have the function of inputting graph directly from equation, so it is very difficult to process the contour of function equation curve.

The programming method of machining center: the contour composed of simple contour line and arc is directly programmed with G code of NC system. In this paper, the complex outline of three-dimensional curved surface is drawn with CAD / CAM software in the computer. According to the type of curved surface, the corresponding parameters are set, and the NC machining program is automatically generated. The above two programming methods can basically meet the requirements of NC machining.

The process of large-scale mechanical parts processing plant is to change the shape, size, relative position and nature of the production object on the basis of the process, so as to make it into finished or semi-finished products. It is the detailed description of each step and each process,

The specific technical requirements are as follows: ‘

(1) Remove oxide scale from parts.

(2) The unmarked shape tolerance shall meet the requirements of gb1184-80, and the allowable deviation of unmarked length dimension shall be ± 0.5mm. The tolerance zone of casting is symmetrical to the basic dimension configuration of blank casting.

(3) When assembling rolling bearings, it is allowed to use oil heating for hot charging, and the oil temperature shall not exceed 100 ℃. There should be no scratch, scratch and other defects on the surface of parts.

(4) When assembling the hydraulic system, it is allowed to use sealing packing or sealant, but it should be prevented from entering the system. Before assembly, the main fit dimensions of parts and components, especially the interference fit dimensions and relevant accuracy shall be rechecked.

(5) The parts and components to be assembled must have the certificate of inspection department before they can be assembled. Parts must be cleaned and cleaned before assembly, without burr, flash, oxide scale, rust, chip, oil stain, colorant and dust.

(6) Parts shall not be knocked, touched, scratched or rusted during assembly. When fastening screws, bolts and nuts, it is strictly forbidden to strike or use improper screwdrivers and spanners. After tightening, the screw groove, nut, screw and bolt head shall not be damaged. For fasteners with specified tightening torque requirements, torque wrench must be used and tightened according to specified tightening torque. After bonding, the excess adhesive should be removed. The semicircular holes of the bearing outer ring, the open bearing seat and the bearing cover shall not be stuck; the semicircular holes of the bearing outer ring, the open bearing seat and the bearing cover shall be in good contact, and they shall be in uniform contact with the bearing seat within the range of 120 ° symmetrical to the center line, and the machining of Dongguan Mechanical parts and the bearing cover within the range of 90 ° symmetrical to the center line. When checking with a feeler gauge within the above range, the 0.03mm feeler gauge shall not be inserted into 1 / 3 of the outer ring width. After assembly, the outer ring of the bearing shall contact the end face of the bearing cover at the locating end evenly.

In the process of processing large parts, we still need to pay attention to the safety aspects

1. The cutting tool must be clamped firmly, otherwise it is not allowed to drive.
2. When moving the worktable and tool rest, loosen the fixing screw first.
3. When milling various workpieces, especially during rough milling, slow cutting should be carried out at the beginning.
4. When loading and unloading tools, use copper hammer or wooden mallet to gently hit to prevent tool fragments from flying out and injuring people.
5. Before work, check the operation of the transmission part of the machine tool, and install the baffle of the machine tool before operation.
6. The work object should be clamped with pressing plate, screw or special tool. The general wrench is not allowed to add casing, so as to avoid slipping and injury.
