Machine Saws
I. Table band saw
II. Portable circular saw
III.Sabre saw
Table band saw
• Band saw is a saw that contains band saw blade that
rides on the two wheels rotating on the same plane.
• used for resawing or ripping lumber into thinner
slabs.
• The tooth of the band saw varies with the material to
be cut and the direction of the cut.
• For rip cuts and crosscuts in softwood , rip angle is
between 10 and 30 degree and in hardwood is 0
degree.
Portable circular saw
• It is a portable mechanical and used for cutting
boards and planks .
• The saw base and the blade can be adjusted to cut at
various depths .
• It has the spring guard that opens automatically when
cutting .
Sabre saw
• used for cutting plastics sheets and polypropylene
sheets in prosthetic and orthotic fields .
• The blade moves both up stroke and down stroke
motion .
Machine Planes
• Single planers or surfacers
• Used to plane or finish the surface of boards and
joining.
• Stock is fed through a planner by pushing it into the
rotating cutter head.
• Thickness planer
• Used to plane boards to precise thickness and for
squaring the width and thickness of timbers.
Machine Drills
• Twist drills
• On standard drill, it has point tips, the lip angle .
• Can give more cleaner overall cut.
• Can be used in drill wood, soft metals such as
aluminium , copper, brass ,plastics and composites.
• Twist drill with centring tip
• It has centring tip and two cutting lips.
• Twist drill with two flutes are best for drilling soft
and hardwood.
• Forstner drills
• Have shallow, cylindrical cutting heads, short
centring tips and two cutting lips.
• Can give the flat bottom holes.
• Used for drilling in softwood, hardwood and plastics.
• Not suitable for drilling deep holes .
• Countersinks
• Have a conical shape.
• Used in drilling out the end of the hole to allow flat
headed screws to be seated.
• Countersinks holes are in rough surface .
• Deburring tools
• Have cone shaped tips.
• One cuts in clockwise direction and the other in
counter clockwise direction.
• The finished holes are clean.
• Valve cutters
• Used for cutting precise seats for the prosthetic
valves.
Router / Carver
• Used for shaping wood , cork and plastics / laminates.
• The shaft is driven by two speeds electric motor.
• Consists of interchangeable bolts .(various cutters,
rasps, and arbours )
• The shaft can be locked with electromagnetic brake .
• A vacuum system is to suck away sawdusts.
• An emergency stop allows immediate shut down.
Knife blade cutters
• Have one or two removable cutting blades .
• Used for initial preparation and shaping of softwoods.
• There are three shapes .
Grinding rasps
• Used for fine grinding of wood, cork, plastics and
laminates.
• They are available in…
Slot cutters
• With two fixed blades.
• Used to cut slots for hardwood tongue and groove
construction.
