Milling spindles are responsible for the turning a piece of workpiece into a finished product. Various tooling interfaces are used to hold the cutting tool, including, for instance, HSK (medium-speed handwheel taper), SK (Quick-release taper), or V-Tension (vertical torque-set taper). The hydraulic, pneumatically, electrically or electronically driven release link allows for easy tool change of the grinding tool. This is why it is important that milling spindles can withstand wear and tear during repeated use and should be regularly inspected.
The first step in the maintenance of a grinding machine is to set up the machine. The basic requirements are a grinding wheel and cutter block for a single machine. Other basic machine requirements are an appropriate supply of energy and an appropriate supply of power. All such requirements must be satisfied in order for the machine to perform its job efficiently.
When the wheel and cutter block are mounted on the workpiece, they must be properly aligned. After they are properly set up, the workpiece must be assembled. After assembling, the cutting machine must be turned on and ready to start the grinding process. There are two types of grinding systems available, rotary and reciprocating. Each type has different advantages and disadvantages. Reciprocating grinding machines require less maintenance than rotary ones and the operation can be easily interrupted. However, the rotary type is usually more powerful, which means that it will produce more cutting results for the same amount of work.
Rotary grinding machines operate on a similar principle to reciprocating machines; however, there is one difference between them. In a rotary machine, the grinding and cutting is done in a clockwise rotation. With reciprocating machines, the grinding and cutting is done in a counterclockwise rotation. Because of this difference, it is imperative that both the cutting and grinding systems are balanced to ensure smooth and accurate results.
To maintain your grinding machine, you must inspect the grinding gears after each use. If the gears are worn or dirty, replacing the old ones with new ones can provide you with smoother grinding performance. If the gears have rust, then the rotary parts can be replaced and lubricated with silicon grease. After replacement of the rotary gears, it is advisable to check whether all the moving parts of the spindle are fitted tightly and if the belt is tight enough to hold the rotating elements. If any problems are detected with the motor, a quick check using a screwdriver can ensure that the gear is not stuck. at a proper speed and correct direction to avoid damage to other parts.
After a few years of steady use, good quality, durable, precision grinding parts are essential to ensure consistent grinding performance. It is also advisable to buy a quality grind machine with an extended warranty and service contract, to help keep the machine running for a longer time.
