~2600 Bowl Lathe~
~A
LATHE FOR BOWL TURNERS
Designed
in conjunction with Keith Adams, a very talented professional Bowl Turner, the
Vega 2600 is made specifically for Bowl Turning, with the capacity for very
large workpieces.
We have paid particular attention to a design that provides great
resistance to oscillation (Gross Low Frequency Vibration).
All loaded components must also be designed to resist higher frequency
vibration when turning heavy and greatly unbalanced blanks.
The Vega 2600 has a drive system that provides very low RPM's, very high
torque and continuously variable speed.
Another very important objective is to provide an outstanding value to
our customers.
~CONTROLLING
VIBRATION AND OSCILLATION
Excessive
vibration and oscillation become a problem when turning large and unbalanced
shapes. While
low RPM's are essential, having great mass properly placed and to use the best
materials is equally critical.
The most effective placement of mass is around the spindle center.
Adding weight to the Lathe at any location helps, but as its distance
from the center of the rotating turning increases, its effectiveness rapidly
decreases. Adding
weight to the base of a Lathe helps, but mainly to prevent walking or toppling.
Materials to a lesser degree also affect vibration, mainly at higher
frequencies. Cast
Iron is somewhat better than steel in absorbing vibration, but concrete is 20
times better than cast iron.
The Headstock on the 2600 is a 64-pound rectangular steel tube filled
with 100 pounds of concrete.
This combination has the very high strength of steel, and the unusually
effective vibration absorbing capacity of concrete, with lots of mass
surrounding the spindle.
~RIGDITY
(LACK OF DEFLECTION)
All
components that are subject to rapidly varying load need to be very rigid, as
any deflection causes vibration.
Steel (being almost twice a stiff as Grey Iron) is frequently the optimum
choice. Shape
is also a very important consideration in machine design in order to reduce
vibration.
~CONVENIENCE
(ERGONOMETRIC DESIGN)
Turning
large bowls can be quite physically demanding.
Good Lathe design can reduce these demands considerably.
Hollowing out bowls is particularly demanding if it requires leaning over
a Lathe Bed. The
design of the 2600 yields an exceedingly comfortable machine to use.
~PENDANT
CONTROL
The
Electrical Control is mounted on a pivoting pendant arm, making it convenient
for all turning operations.
~AC
MOTOR
(standard)
(1.5
HP, or phase 3)
The
AC Drive model has a low and a high speed range.
Spindle Speed is continuously variable in both high and low range by
means of a hand crank.
Speed in a low range is 160 to 425 RPM.
High range speed is 800 to 2200 RPM.
A reversing drum switch is located on the pendant arm for Forward / Off /
Reverse.
~DC
DRIVE
(optional)
(1.5
HP, 220 volt 1 phase)
DC
motors can rotate a workpiece at very low RPM's, but the spindle torque will be
very low compared to running the motor faster.
Consequently we utilize a compound belt reduction, in combination with
the DC motor/controller, to provide very high torque at very low speeds.
5/8", "B" section Vee Belts are used for very effective
power transmission.
The
DC motor controller (mounted on the pendant) features a rotary speed control
dial, spindle reversing switch and motor brake.
Speed range is from 0 to 425 in the low range and 0 to 2520 in the high
range.
~TOOL
REST ASSEMBLY
The
Tool Rest Base is fabricated from two 1 1/4" square steel bars for extreme
stiffness. It
weighs 17# and is surface ground for predictable and smooth motion.
Locking of the base is achieved by cam action using the extra long
pivoting tee handle.
The Tool Rest has a 1 1/4" shank welded to heavy steel cross bars,
yielding great stiffness…they will never break (GUARANTEED).
~GUARDING
The
2600 Lathe is supplied with heavy Steel Mesh Guard that offers a great deal of
protection. It
may be removed or swung out of the way for spindle access.
WE RECOMMEND USING GUARDS FOR ALL TURNING!
~LATHE
SPINDLE
The
spindle is 1-1/4" diameter, supported by three (3) sealed for life ball
bearings. Thread
size is 1-1/4"-8 tpi.
~TAILSTOCK
The
2600 Tailstock is designed so that it can be easily removed, when not required,
by backing out of the 5/8" clamping bolt.
No wrench is required.
With the Tailstock removed only the short 16" bed remains between
the Turner and the spindle.
This gives the same access to the work as in OD turning.
The Tailstock Spindle is #2 MT with a total travel of 9".
The Live Center is adjustable from 6" to 15" away from the
Headstock Spindle Nose.
~LATHE
BED
The
Lathe Bed is an unusually wide 13 inches that completely supports the Tool Rest
Base for most work.
It is made from 3/4" thick, surface ground steel.

REMOVED
Removing
the Tailstock allows for excellent accessibility to the Spindle.
Much emphasis has been placed on making this machine comfortable and easy
to use.
~TRANSMISSION
A
pair of 7.5" diameter pulleys and jackshaft, coupled with adequate
horsepower provides the power for this Lathe.
Easy access to the belts makes for easy changes from high to low range.
A Hand Crank adjusts the speed of AC Motor Lathes and allows shifting
from high to low range on both AC and DC models.
