Deep Drilling Machine

Multiple-spindle drilling machines are used for mass production. These machines are great time savers where many pieces of jobs having many holes are to be drilled. Multi-spindle head machines are used in mechanical industry in order to increase the productivity of machining systems. The multiple- spindle drilling machine is a production type of machine. It is used to drill several holes in a work piece simultaneously, in a single setting. This machine has many spindles driven by a single motor and all the spindles are fed in to the work piece simultaneously. These machines may be either horizontal or vertical type. The drill heads consists of several spindles mounted on angular contact ball bearings and driven by a set of gears. For spindles wherein the center distance are very close needle roller thrust bearings are used. The drive to the spindle is by AC spindle CNC motor or by AC induction motor. The speed of the spindles driven by induction motor is varied by using variable frequency drive. The drill head is interchangeable. These multi spindle drilling machines are mainly used in automobile industries for drilling holes in crankcase, cylinder head, connecting rod etc. The drill head is supplied with high pressure through coolant or external coolant depending on the application. The drilling feed is provided by a CNC table or a hydraulic table. The drills are guided in a mobile jig plate or a fixed jig plate depending on the application. The drills are mounted on to the spindle using an adjustable adaptor or a stub tool holder.

Fine Boring Machine

The machine has been designed to do fine boring of the connecting rod used in the defence sector. The machine has four high-precision spindle units with class ultra-precision bearings which provide accuracy and rigidity to the spindles. The structures of the machine are built by heavily ribbed weldment which provides rigidity and stiffness. The machine is also equipped with high pressure through spindle coolant for achieving the best quality of components. The machine comprises two fixtures mounted on a CNC slide for fine boring the connecting rod. Generally, con rod boring can be completed in several machines. But in this machine, the parent steel bores, bush bores and pin bores are all completed in one machine with three setups. This machine can produce fine bores having taper, cylindricity and ovality of less than 5 microns with very fine surface quality as specified by the customer.
