Relevant issues to pay attention to when maintaining a milling machine

A milling machine is a machine tool that uses a milling cutter to machine a variety of surfaces on a workpiece. Usually the rotary motion of the milling cutter is the main movement, and the movement of the workpiece (and) milling cutter is a feed movement. It can process planes, grooves, as well as various surfaces, gears, etc. A milling machine is a machine tool that uses a milling cutter to mill a workpiece. In addition to milling planes, grooves, gear teeth, threads, and splined shafts, milling machines can also process more complex profiles with higher efficiency than planer machines and are widely used in the machinery manufacturing and repair department.


Milling machine protection scope


1. Cleaning of bed and parts, cleaning of iron scraps and surrounding environment sanitation, cleaners, clamps, measuring tools;


2, check the oil level, not below the oil mark, add the various parts of the lubricant.


Milling machine weekend maintenance work scope


One, milling machine cleaning


1. Disassemble and clean the various parts of the oil felt pad;


2. Wipe each sliding surface and rail surface, wipe the workbench and the horizontal, lifting screw, wipe the transmission mechanism and knife holder;


3, wipe the dead corner.


Second, milling machine lubrication


1, the oil hole clean and add lubricants;


2. Each Guide Rail surface and sliding surface and each screw is filled with lubricating oil;


3, check the milling machine transmission oil tank body, oil surface, and refueling to the elevation position.

Third, the milling machine is tightened


1. Check the milling machine and tighten the platen and insert screws.


2, check and tighten the slider fixing screw, the transmission mechanism, hand wheel, table bracket screws, fork top wire.


3. Check for loose screws in other parts.


Four, milling machine adjustment


1. Check and adjust the elasticity of the belt, the pressure plate and the insert.


2, check and adjust the slider and screw together.


Fifth, milling machine antisepsis


1, remove all parts of the rust, protect the paint surface, do not collide.


2. The milling machine is disabled, the backup device guide surface, the sliding screw handwheel and other parts exposed to rust easily rust and corrosion.

Geared Traction Machine For Elevator / Lift, Elevator Spare Parts.

Geared traction machines are driven by AC or DC electric motors. As the name implies, the electric motor in this design drives a worm-and-gear-type reduction unit, which turns the hoisting sheave. While the lift rates are slower than in a typical gearless elevator, the gear reduction offers the advantage of requiring a less powerful motor to turn the sheave. These elevators typically operate at speeds from 38 to 152 meters (125-500 ft) per minute and carry loads of up to 13,600 kilograms (30,000 lb). An electrically controlled brake between the motor and the reduction unit stops the elevator, holding the car at the desired floor level.
