Abrasive
Jet & Water Jet Cutting Machines
Perfect Technology manufactures both an Abrasive Jet and Pure Water
Jet Cutting Machine. The Waterjet
system is an ideal machine for the cutting of various materials and is extremely
versatile compared to alternative machinery such as lasers and plasmas. Waterjet
cutting is performed with pure water for the cutting of - foam, package
products, gaskets, gibson board, carpet, food, rubber, and many other soft
materials. The addition of abrasive
(garnet ) to the water stream provides the ability to cut - steel, stainless, copper, aluminum,
granite, marble, laminated glass. In
general soft materials are cut at a lower pressure range of 40,000 50,000 psi
with hard materials requiring the higher 50,000 60,000 psi. The Waterjet cutting process does not
generate heat; elliminating the warping of materials like copper and aluminum.

CUSTOM SIZED & FEATURED SYSTEMS
PTC has the flexibility to custom fabricate any table size. All engineering and fabrication is performed by
in-house staff. Our sales team would be
pleased to discuss your application in detail and propose a machine design to
meet your needs. Material test cutting
by PTC is available and recommended.
Test results provide a customer an opportunity to evaluate - edge
quality and actual cut speed. PTC
engineering also offers specialized features such as gantry mounted drill
heads and ink printer, clamp down systems, noise abatement enclosures,
conveyors, dual shuttle systems, and material lifting systems.
PURE WATER CUTTING
Based on the media to be cut, PTC can offer cutting systems with cut
speeds that will exceed 4000 inches per minute.
This speed is triple other water jet manufacturers capability due to the
PTC state of the art Linear Drive motion system. Pure water systems are designed with the
gantry across the tables short direction, this reduces gantry weight and is ideal
for loading / unloading in combination with a conveyor system or shuttle system
for increased productivity. Soft materials are typically cut using a
sapphire orifice ranging in size from 0.005 0.007 at extremely high speeds
with multiple cutting heads to maximize productivity.
Pure Water 7 x 14 System, Dual Shuttles , 3 Cutting Heads
ABRASIVE CUTTING
Hard materials require the addition of garnet mixed within the
water stream. The abrasive delivery system
consists of three components - a bulk garnet hopper, a metering device to
regulate garnet mixture, and a mixing chamber within the cutting head. Abrasive cut speed range from 1-500 inch per
minute based on material hardness, thickness, and cut quality. The
use of diamond orifice is common to increase cutting accuracy and provide
longer replacement intervals. Based on available horsepower the typical orifice
size for abrasive cutting will range from 0.010 0.018. As one increases orifice size the cut speed will
increase by ten to twenty percent.
 
STRUCTURAL CONSTRUCTION
All PTC Waterjet systems are fabricated from stainless steel
construction and 100% TIG welded, each frame includes a five year structural
warranty. The high pressure water
coupled with abrasive is a harsh environment.
Waterjet tables fabricated from mild steel and painted begin to rust
process in a short period of time and if not periodically repainted becomes
structurally unsafe. PTC gantry system
is fabricated from extruded aluminum.
Even electrical access panels have stainless steel machine screws.
All PTC abrasive
machines have cut bed=s fabricated from
galvanized steel slat material mounted above the water collection tank. Slats are mounted on 1.187@ centers and held into
place by stainless steel comb cut support members. Design is such that slat material is easily
renewable. For pure water cutting
of small parts, corru-plastic material can be easily placed on top of the steel slats
and the cutting head elevated as necessary.
The abrasive systems
require 32-34 inches of water to dissipate the water / abrasive stream energy. Less than 30 inches of water with time could
cause structural damage (potential hole) to the bottom of the tank. High pressure water does not have the same
energy without the abrasive additive, therefore a stainless steel collection
trough is provided with pure water systems.
LINEAR DRIVE MOTION SYSTEM
All PTC Waterjet systems are equipped with a state of the art Linear Drive motion system
for powering the gantry and cutting head movement. This system consists of a computer controlled
linear induction motor, magnetic coupled by rail mounted inert magnet
sets. This drive package transmits power
without the use of any mechanical components and operates without
racks/pinions, drive belts/sprockets or ball screws. Elimination of
these components improves mechanical reliability and reduces maintenance.
THE LINEAR ADVANTAGE
The best positioning
accuracy in the marketplace - +/-
0.001
No components to wear
- the same level of accuracy every year
!
Repeatable Backlash +/- 0.0005 without software compensation
No lubrication required,
ideal for dirty abrasive environment.
Fully in-capsulated
motor windings - simply clean with a water hose.
Maximum cut speeds exceed
4000 inch per minute.
Designed for 24 hr / 7 day operations - highly reliable technology.
Rack / Pinion Issues a
common issue is premature pinion wear. Should
abrasive overspray be introduced within the lubricant it accelerates pinion
wear. Once the pinion is partially
worn, accuracy and backlash are less than desirable. Some companies attempt to compensate for pinion wear by
software adjustment.
Ball Screw Issues have a limited table length and require
backlash nuts to partially compensate for backlash concerns. Backlash nuts require periodic
replacement. Limited speed
capability. Lubrication is required.
Belt / Sprocket issues - the
belt systems will operate at higher speeds but lack the positioning accuracy of
the Linear.
OPERATIONAL SOFTWARE
The operational software is designed exclusively for the PTC
Waterjet. All operational software is
written and updated by PTC in-house programmers. The software package is designed to read G
code cut files created from the post processing software. The G
code file is an inclusive cut file designated cut speeds, lead-ins, type of
hole pierce, abrasive metering.
The operator has excellent control to include:
Feedrate override
Pause and reverse feature.
GO TO any location within the cut file routine.
Array up to six independent cut files.
Coordinate rotation X, Y
REMOTE PENDANT
A hand held control unit is standard with each system. This allows the operator to manually make
adjustments in the X, Y, Z axis in a slow or fast pace. A time saving feature is the 45 degree
button to simultaneously move in the X and Y
axis.
DIGITIZING CAMERA / SOFTWARE
Every PTC waterjet is equipped with its own digitizing software
and camera system to trace a flat irregular pattern directly on the machines cut
bed. The software outputs a DFX file ready
for post processing to a G code cut file.
Setup and file creation is quick and accurate enabling the user to handle
odd shaped patterns that otherwise would be time consuming and difficult to
formulate by measuring and drawing in AutoCad.
