  SHAPER MACHINE: TYPES, PARTS, WORKING What is  shaper machine ? and  types of shaper machines  with their parts and working principle. Shaper and Types of Shaper Machines The  shaper machine  is a reciprocating type of machine basically used for producing the horizontal, vertical or flat surfaces. The shaper holds the single point cutting tool in ram and the workpiece is fixed in the table. During the forward stroke, the ram is holding the tool is reciprocating over the workpiece to cut into the required shape.  During the return stroke, No metal is cutting. In the shaper machine, the rotary motion of the drive is converted into the reciprocating motion of the ram holding the tool. Therefore in order to reduce the total machine time, It allows the ram holding the tool should move slower during forwarding cutting stroke and it comes faster in return stroke.  This can be achieved by a mechanism called a  quick return mechanism.  Shaper Machi...

  DIFFERENT TYPES OF NUTS AND BOLTS   A bolt contains two parts a  shank  and head. The cylindrical portion of the bolt is known as the shank. The shank is threaded at the tail end for a sufficient length so as to effectively engage with a nut. The shape of the head is depended upon the purpose for which bolt is required. The  nut  is a type of a  fastener  which has a  threaded   hole  in it. The nut is always used in joining with a  mating bolt  to fasten various parts together. Different forms and  types of nuts and bolts  are as follows: Form of Bolts Hexagonal-headed bolt Square-headed bolt Cylindrical or cheese-headed bolt Cup-headed or round-headed bolt T-headed bolt Countersunk-headed bolt Hexagonal-headed bolt This   is the most common form of a bolt and is used for general fasting purposes. The hexagonal head is  chamfered at its upper end. To prevent rotation of the bolt while ...
