Angle Drills Can Save on Large Work Parts Processing Costs

Transmission devices such as angle drills or multi-axis drills can be attached to processing equipment to improve production efficiency. Angle drills can be used to process hard-to-reach parts, while multi-axis drills can be used to shorten the main processing process time through parallel processing in a one-way injection.

The cost of clamping, turning, re-clamping, calibration, bottom-up drilling and threading of a steel component of wind energy equipment on a vertical lading is enormous in terms of the oversized scale (up to several meters in diameter) and weight of the work piece. Although Sket Maschinen-und Anlagenbau specializes in processing large work parts weighing several tons, its specially designed Romai special angle drills are competitive and save these processes in batch processing. In this regard, from the beginning on the vertical lading can be raised ring steel structure components, so that it is a distance away from the ground, it is clamped. In the absence of changes in the clamping position, angle drill bits are used to drill holes and thread from the bottom up. Compared with the previous drilling method, the angle drill can shorten the working time by about 3h for each work piece processed.

Use multi-axis drills to reduce the main processing process time.

The parts of wind energy equipment processed in bulk are still moderate in scale. This madeburg-based company specializes in the processing of large and heavy metal work pieces. For example, the company's crib is suitable for processing components up to 300t and 13,000mm diameters. At approximately 23,000m2 processing sites, approximately 80 machine tools are adapted to a variety of chip-removal processes that can be used to manufacture equipment components such as wind and hydro turbines and generator components to achieve the required processing accuracy.

Similar to parts machined with angle drill bits, the use of multi-axis drill bits can also achieve time-saving purposes.

By processing multiple boreholes side by side on one process, the main processing process time can be shortened, which can be achieved to improve the efficiency of rationalization. A typical example is the processing of fixed holes on the circumferonal surface of a steel component. For such batch processing occasions, the company orders this dedicated Romai multi-axis drill bit every time it technology to the co-factory. Typically, such multi-axis drills are considered fixed multi-axis drills with rigid boring boring heads and up to five machining shafts, while matching each device. The Vaihingen/Enz company can take inspiration from its extensive experience and 252 spindle technology solutions.

Dynamic balancing ensures approximate vibration-free cycle operation.

Like angle drills, the multi-axis drills developed and developed cater specifically to specific processing requirements. Special milling bearings should be used if the angle drill is specifically used in machining applications with high torques, and high-precision spindle bearings are used for finishing operations at high speeds. The tapered gear drive system with Gleason arc meshing or cycling quasi-ingression line engagement and special coating ensures smooth operation and high torque transfer.

On multi-axis drills, the drive gears are tilted or edge polished. With dynamic balancing calibration, approximate vibration-free circular operation can be achieved. In addition, the operating surface of the seal is coated and polished to prevent the seal from touching each other causing the spindle to roll. For hard-to-cut machining applications, such as Sket's, high-carrying advanced conical roller bearings are used on multi-axis drills. As a result, high processing accuracy can be maintained even under very demanding processing conditions.
