For someone who operates a small business and experiences a breakdown of one or more milling machines, the result is a combination of lost production time and the high cost of taking the milling equipment to an expert technician for refurbishing. Moreover, the owner of the milling equipment must pay for expensive replacement parts. Instead of contacting a technician to refurbish milling equipment, craftsmen can perform refurbishing jobs that include changing the motor, drive belt, timing belt and brake shoes.
Change the Motor
Even the most durable motors eventually fail to power milling machines. The most important facet of changing milling equipment motors involves removing the motor from the machine. First, you must cut the power and allow the motor to cool off before commencing with the removal process. Second, remove the housing screws, which opens the motor's housing. Consult the owner's manual for specific step-by-step instructions for removing the motor housing. Third, remove the screws that attach various parts, such as discs, to the motor. Craftsmen may have to pull back on one or more belts to extract the motor from the milling equipment.
Replace the Drive Belt
A drive belt that breaks or even weakens slightly can diminish the performance of milling equipment. After removing the motor, milling machine operators use a milling tool to remove up to three screws to access the drive belt. The motor's top housing also requires removal by hand. Confirm the location of the drive belt by referring to the detailed parts diagram within the owner's manual. Remove the deteriorated drive belt and replace it with a new belt, preferably constructed by a brand name manufacturer. Replace each screw in the exact spot where it helped secure the drive belt.
Replace the Timing Belt
Milling equipment timing belts ensure the machine provides steady performance for both small and large milling machines. Lower the quill as far as it can go and then remove the screws attached to the speed charger housing. Do it yourselfers should organise the screw set to remember which screw goes into its correct hole. Then, take out the four screws that hold the top assembly. The old timing belt should come out easily, with the new timing belt secured within the top assembly.
Change the Brake Shoes
Milling equipment brake shoes control the speed of the spindle or rotor. As with brake pads that provide braking power on vehicles, milling equipment brake shoes inevitably wear down due to frequent use. Brake shoes do not require craftsmen to remove the milling equipment motor. They simply remove the top section of the milling machine that involves unscrewing a couple of screws and taking out the clutch hub assembly. When a craftsmen replaces the brake shoes, they may also want to replace the drive discs and bearings to ensure optimal brake shoe performance.
