advantages

disadvantages
|
Abrasive cut-off saw
|
- low cost machine
- low cost blade
- portable
- can cut fully
hardened steel, HSS etc.
|
- cuts not
straight
- 90 degree cuts
only
- rough cut, large
burr
- “Grinds” not
“cuts”
- heat burns and
stresses steel
- sparks create fire
hazard
- high noise level
- dirty – abrasive
grit and grind particles
scatter
- blades
disintegrate rapidly
- eye protection
required due to high velocity particles
- non-ferrous
metals load up blade
|
Carbide “dry-cut” hi-RPM chop saw
|
- moderate
machine cost
- fast
cutting cycle
- OK
cut quality
- Portable
|
- high
blade cost
- dangerous
chips and carbide particles
- 90
degree cuts only
- high
noise level
- light-duty
vise
|
|
Horizontal bandsaw (small
type)
|
- moderate
machine cost
- moderate
blade cost
- cutting
capacity
- self-feeding
(some models)
|
- slow
cut rate
- no
mitre cuts (except high-priced models)
- rough
cut
- blade
can “wander”
- blades
not re-sharpenable
|
Cold saw
|
- straightest
cuts
- smoothest
cuts
- mitre
cuts both ways
- fast
cutting cycle
- no
heating of workpiece
- little
or no burr
- low
cost blade sharpening
- lowest
cost per cut
- no
high speed particles or chips
- 3-phase
motor for economy and durability – high voltage options
|
- higher machine cost
- cutting
capacity limited by blade size (for example 4” for 14” saw)
