fabrication of multi drill holder pdf

SYNOPSIS

The MULTI DRILL HOLDER (Eccentric Drive) is one which can be used to drill a number of holes at various large and even unsymmetrical layouts according to our requirements, where the conventional Multi spindle Drill Heads cannot be used. This is an improvement over geared drill heads and drill heads adopted with universal joints. This is an improvement over geared drill heads and drill heads adopted with universal joints.

The drill head is mounted on the drilling machine table. The drill hea ....etc

Introduction
In order to analyze the roller burnishing operation on a
quantitative basis, certain observations must be made.
One of the important observations is the measurement of
components of cutting force. A dynamometer (Shaw,
1969) is used to measure forces that occur in metal
cutting or any other operation. Cutting force is one of the
parameters which play a great role in machining and for
obtaining better surface qualities like surface finish,
surface roughness and accuracy of dimensions. Hence, it
is required to measure compo ....etc

design and fabrication of pneumatic auto feed drilling machiner eport

abstract

in small-scale industries and automobile maintenance shops, there are frequent needs of
tightening and loosening of screws, drilling, boring, grinding machine. huge and complicated
designed parts cannot be machined with the help of an ordinary machine and further for every
operation separate machine is required therefore increasing the number of machines required and
increasing the area required for them to be accommodated and hence overall initial cost req ....etc

SPLIT-PIN DRILL JIG
A commonly-used means for preventing nuts coming loose from bolts in service is the use of split pins. It is is inserted between the castellations of a special castellated nut, and through a hole in the bolt, until the head of the pin fits between two castellations. Then The split ends of the pin are then bent over for locking the nut onto the bolt. A disadvantage of this method is that when the nut is tightened on the bolt, the gaps between the castellations may not line up with the pre-drilled hole in the bolt.
