How to Prevent Tilt During Drilling Center Holes on Planar End Surface Machining Centers

The planar face boring machine with a central hole feature boasts high rigidity, precision, flexibility, stable operation, and high processing efficiency. It is an essential and ideal machine tool for the precision processing of automotive components such as half shafts, camshafts, crankshafts, transmission shafts, and motor shafts.

Industry experts are well aware that during the operation of a flat-end face boring center hole machine, it is inevitable that there will be issues with the drilling offset in deep-hole machining. What should be done in such cases? Below, we will explore the preventive methods: 1. Firstly, consider the motion form adopted by the flat-end face boring center hole machine. In the process of deep-hole machining, the control of the workpiece's deviation is achieved through a dual rotation of the workpiece rotating and the tool rotating in the opposite direction while also performing feed movement; secondly, a single rotation where the workpiece rotates and the tool performs feed movement: the single-rotation method where the workpiece remains stationary and the tool rotates and performs feed movement is less effective compared to gun drilling.

2. The selection of cutting parameters can also have a certain impact on the degree of deviation. It is not advisable to use large feed rates without affecting production progress, as increasing feed rates can negatively affect the deviation of the hole. 3. The grinding angle of the drill bit can also affect the degree of deviation of the processed hole. It is recommended to consider different deep hole drill bit grinding angles for different materials and drill hole diameters to achieve better hole deviation. 4. The uniformity of the material of the workpiece being processed also has a significant impact on the deviation. During the processing, the deep hole drill bit will shift towards the softer material. Therefore, in deep hole processing with high requirements for deviation, the heat treatment of the material is very critical. It is important to refine and uniformize the material structure as much as possible.
