Wire EDM

This is where it all began!  RPG Industries began as a Wire EDM Job Shop.  Our technicians have over 60 years combined experience in Wire EDM.  Our "outside the box" thinking separates us from other providers.

High-speed Wire EDM Machines compete with more traditional machining processes, such as milling and grinding.
Parts can be processed after material is hardened. This eliminates the possibility of distortion caused by the heat treat process.

Wire EDM, being a non-contact process, also eliminates machining forces that can cause distortion.
Repeatability between parts is extremely high. This is due to the fact that there is no cutter wear as in conventional machining.

Conventional EDM

Conventional EDM (Sinker EDM machining), like Wire EDM, uses spark erosion to machine blind cavities.

This process employs machined electrodes that produce sparks along the surface of the electrode to sink or plunge the cavity. The Conventional EDM process is ideal for a number of applications:

Blind Cavities
Intricate Details
Sharp Corners
Fine Finishes (Surface Finishes to 10 Micro-Inch)
Thin Walls and Cross Sections
Machining Threads into Hardened Parts
Blind Keyways
Internal Splines, Squares, or Hexes
Tolerances to +/- .0001”

Any conductive material can be Conventional EDM machined, including aluminum, brass, carbide, copper, hastalloy, inconel, steel, stellite, and titanium.  RPG Industries has in-house electrode manufacturing capabilities.

Electrodes for Conventional EDM machining are generally made from copper, graphite, or tungsten depending upon work piece material and electrode wear requirements.

Small Hole EDM

​Small Hole EDM drilling uses the same spark erosion principle as Conventional EDM.  Small Hole EDM is ideal for adding ejector holes in hardened punches, coolant holes in cutting tools, vent holes in molds, and start holes for Wire EDM.

RPG Industries offers Small Hole EDM Machining capabilities from:

.006" diameter to .140" diameter
10" drilling depth
Up to 850 pound workpiece weight

Any conductive material can be Small Hole EDM machined, including aluminum, brass, carbide, copper, hastalloy, inconel, steel, stellite, and titanium.
Abrasive Water Jet
Water Jet machining is a computerized cutting technology that cuts virtually any material.  It is a clean process that does not result in heating or residual stress in the cut materials.  WaterJet allows for very fast cutting while minimizing material waste as is common with other machining technologies.  Intricate cutting geometries are also possible with tight radii and sharp corners easily maintained.

All metals can be machined by Water Jet including aluminum, brass, bronze, copper, steels, nickel alloys, titanium, soft metals, & metal composites.

Non metallic materials are particularly suited for cutting via Water Jet. Examples include carbon fiber
composites, ceramics, granite, glass, refractories, laminates, marble, plastics, concrete, and natural stone.

Rubber, plastics, elastomers, foams, synthetic fiber materials, paper, and wood are readily cut with Water Jet.  Many of these are cut with water only (no abrasive).

Major benefits include :
• NO heat generated structural changes – this is a cold cutting process
• Virtually burr-free cut edges - reduces finishing operations
• NO material discoloration or oxidized edges
• NO toxic or fume discharge

Tolerances for high-speed cutting are typically held to +/- 0.005 to .010 inch.

Water Jet alone or combined with other machining technologies such as CNC milling can result in vast savings of process time and fabrication cost.  When applicable, Water Jet cutting has significant advantages over competing
cutting methods, such as routers, plasma torch and laser cutting.  Water Jet can cut through materials such
as rock and ceramics that may normally be considered "unachievable" by conventional cutting methods.

CNC Machining

Whether enhancing our Wire EDM, Conventional EDM, or Small Hole EDM services, or complete build-to-print manufacturing, our CNC Machining capabilities can satisfy the most intricate precision tooling requirements.

We have multiple Turning and Milling centers to meet your delivery needs.

Additive Manufacturing

Instead of waiting weeks and paying thousands of dollars for a part, we can 3D print incredibly high-performance parts in our facility faster than would be possible through conventional methods.

By reinforcing your parts with carbon fiber while 3D printing them, we achieve unparalleled strength, stiffness and durability in your printed parts.

We can print with carbon fiber, Kevlar and fiberglass for parts that are as strong as aluminum and dramatically lighter.

For heat tolerance, we will soon be printing with 17-4 Stainless Steel. In the near future we will have the capability to print with Titanium, Aluminum, Inconel 625 and tool steel for most functional applications.
