VERSATILITY.

 
  G&H has variety of different punch presses including a fully automated CNC punching center.  

OTHER FABRICATION

G&H offers a full range of additional fabrication capabilities including:

  • CNC Punching
  • Tube Bending
  • Sheet & Plate Metal Forming
  • Surface and Centerless Grinding
  • Honing
  • Saw Cutting

CNC PUNCHING

G&H has variety of different punch presses including a fully automated CNC punching center. Our Trumpf TruPunch 2020 center is extremely fast and can not only punch holes, but will tap threads, mark, offset, emboss, form flanges, and even deburr parts. It punches 900 holes per minute and travels at speeds in excess of 4,000 inches per minute. This advanced equipment allows us to produce high quality, sheet metal fabrications in high volumes at a reasonable cost and in a timely fashion. 

VERSATILITY IN VOLUMES

Whether you are looking for a prototype or a production run, G&H has the equipment and personnel to handle any job. We can process the most intricate formed features, perforations and patterns with high speed precision. In many cases, CNC punching is the most efficient way to produce precision fabricated metal products with many holes.

In addition, we can deal with components that range up to 50 inches in width and 98 inches in length with a maximum ¼ inch sheet thickness. G&H punches parts for different industry OEMs from a variety of materials including stainless steel, aluminum, and copper. 

TUBE BENDING

Tube bending has long been a need to many across a broad range of industries from oil & gas to structural engineering to automotive and sport utility vehicles. G&H has invested capital as well as maintained a team of experienced operators to provide the highest quality tube bending services.

Because our tube benders are capable of bending and forming both round and square bars and tubes, we offer the most flexible and broad range of services for our customers. In addition, we are capable of both roll and push bending, as well as having the ability to stack our tooling. This allows for multiple diameters to be bent on the same part simultaneously providing the most cost effective solution for multiple bends per part.

G&H provides the following benefits:

  • Both round and square capabilities; able to roll and push bend tubing
  • Ability to bend up to 3.15” round and 2.36” square tubing with a maximum length of 240” long
  • Stackable tooling allows for simultaneous bending of multiple radii on the same part
  • Repeatable accuracy of 1/100th of a degree with electric machinery making it more reliable than a hydraulic bender which is effected by ambient and machine temperatures

SHEET METAL AND PLATE FORMING

G&H offers press braking services for customers needing sheet and plate metal forming. This is one of the most technically challenging operations in metal fabrication. We use only CNC controlled machines which result in tight tolerances and repeatability for our customers. 

ALL SIZES AND SHAPES

We can handle a variety of sizes of material as well as produce a wide variety of shapes. We have tonnage capacities up to 125 tons and can form metals up to ".500” Carbon Steel up to a part length of 36” long/thick. We are capable of press braking parts with a bed size of up to 80" in length. We can work in a variety of metals including aluminum, cold rolled steel, and all alloys of steel.

SURFACE AND CENTERLESS GRINDING/HONING

G&H provides a wide range of grinding services from precision surface grinding to centerless grinding to honing. We have highly skilled operators to provide precision ground surfaces, either to achieve a critical size or surface finish.  Our honing equipment can handle parts with an ID of 3” to 27”.

Precision surface grinding is the most common of the grinding operations. It is a finishing process that uses a rotating abrasive wheel to smooth the flat surface of metallic or nonmetallic materials to give them a more refined look or to attain a desired surface for a functional purpose. Parts require surface grinding for various reasons like:
  • To produce a flat surface
  • For specifying accurate tolerance thickness
  • To obtain a very smooth surface roughness
  • To sharpen a cutting tool

Our automated Chevalier FSG3A1224 surface grinding machine produces high tolerance parts with a mirror-like surface finish, while meeting flatness, parallelism, and squareness requirements. G&H also has two manual Chevalier surface grinders. Known as the “workhorses of the grinding industry” these machines provide slip-free, smooth & accurate table movement, superior accuracy and finish, and excellent rigidity and superior dampening during heavy machining. We regularly achieve tolerances of +/- 0.0001”.

Centerless grinding is an effective method of precision grinding the outside diameter of any cylindrical shaped part such as round bar and tubing, bushings, pins, mixer shafts, pump shafts, & hydraulic cylinders. This shaping technology is an outstanding method of maintaining extremely close diametrical tolerances under high-production conditions. The process can handle diameters from 0.003" to over 3".

Honing is an operation to remove minute amounts of material typically inside a cylinder in order to tighten the tolerance. G&H has the capability to hone parts with inside diameters ranging from 3” to 27”.

SAW CUTTING

From lasers to band saws, G&H has a solution for most metal cutting needs. We have machines that can cut almost any material including wood, plastic and steel. We regularly cut a wide variety of material from shim stock to heavy plate. We have the ability to cut titanium, inconel, hasteloy, cobalt, brass, bronze and many more metals.

Our horizontal band saws can cut various types of tube, rod or extrusions. Many of these saws are automated and programmable for repeatable quality and increased throughput. In addition, we have shearing capabilities most often used in conjunction with another cutting process such as laser cutting in order to make long straight cuts.

Most tubular material must be cut before any machining or fabricating can be done. This can add from two to as many as five days using outsourced suppliers. By having in-house cutting capabilities, G&H saves time and money for its customers.
