Flat lapping is used to achieve extremely exact surface flatness or accuracy. Obtained without the use of special equipment, surface flatness/accuracy ranges from 1-3 HLB (Helium Light Bands), whereas flat lapping can allow for tolerances of as little as 30 nanometers. Used primarily for smoothing surfaces, flat lapping can also be used to obtain a desired surface roughness to exact specification much wider than the range of 1-30 R (average roughness) that can be obtained through regular means. 

Diamond Polishing is a precision process for polishing ferrous and nonferrous materials. Different pads are used based on polishing requirements. Copper plate and aluminum plate are used along with different grade diamond slurries and aluminum slurries to accommodate the requirements of a wide variety of polishing applications for super precision surface finishes and flatness. 

Double disc grinding is an abrasive machining process that removes material from two sides of a part simultaneously. In a typical double disc grinding machine, the grinding discs are side-mounted on a pair of opposed spindles. Because the process grinds both sides at the same time, it offers a high degree of accuracy and parallelism and reduces stress on the part. The process is suitable for a wide range of materials, including stainless steel, sintered metal parts and high-strength alloys. Production rates are generally greater than those obtained with surface grinding. 

Blanchard Grinding quickly removes large amounts of stock quickly and efficiently. In our Chicago location, we have various Blanchard grinder machines that can grind a number of different sizes and shapes of parts. Blanchard grinder machines have the ability to produce 63 micro and better finishes as well as holding close tolerances. 

Surface Grinding is used to produce a smooth finish on flat surfaces. 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. 

Centerless Grinding is a method of material removal through grinding, where the workpiece is set up between the regulating wheel (or backup wheel) and the grinding wheel, and is supported by the work blade (or work rest). Both wheels are rotated in the same direction. 

DedTru grinding machines provide very precise and close tolerance grinding with better concentric roundness finish and profile grinding and is is used for thru feed, infeed, ID/OD plunge grinding of parts which need to be concentric from one diameter to another. DedTru grinding provides exceptional dimensional accuracy and roundness. Cylindrical and round parts measuring in size from 0.005 inch to 5 inches can be ground by thrufeed operation including steps, forms, tapers, chamfers and other OD/ID secondary operations. 

Outside Diameter (OD) Grinding is the opposite of ID Grinding. Material is generally “held” between centers and is rotated as the grinding wheel travels up and down the part. Outside Diameter grinding allows for any cylindrical work piece to be ground to a precise dimension and finish. 

 Inside Diameter (ID) Grinding (or Internal Grinding) is generally done to create a precision surface finish with great accuracy on the inside diameters. With this method the work piece is mounted in a chuck to allow rotation during the grinding operation.

Inside diameter (ID) grinding delivers perfect, functional surfaces in components needed to establish a non-positive connection with an axle or shaft. 

The honing process is used to obtain precise dimensions and surfaces in cylindrical shapes with a wide range of diameters. This applies to parts such as Hydraulic Cylinders, Pistons, Bearing Bores, Pin Holes and to some external cylindrical surfaces. The honing process offers advantages of low capital equipment cost, high metal removal rates, and extreme accuracy of 0.001mm (0.00004´´) in a wide variety of materials. Other advantages include the ability to create round and straight bores in relatively long workpieces. Workpiece bore length-to-diameter ratios of 1.5:1 and longer are ideal for the process. Shorter bore lengths can be accommodated by stacking workpieces in special fixturing. We can correct parts that are not square, within limits.
