Grinding & Machining

CB Manufacturing & Sales has been one of the largest Blanchard Industrial Grinding facility in Dayton and Southern Ohio since 1965. Depending on the material to be ground, our experienced operators are able to hold dimensions of flat and parallel to .001 or better and thickness to +/- .0005.

CB’s well-maintained equipment includes:

  • Three 42″ Blanchard vertical spindle industrial grinders
  • A Blanchard 84″, and the centerpiece of our industrial grinding department
  • A 108″ Mattison capable of handling parts as large as 128″
  • Up to a height of 48″

CB Manufacturing’s Mattison 108 is the largest vertical spindle rotary grinder east of the Mississippi and one of only three in all the United States.

Our operators are truly craftsmen, with years of experience and knowledge that allows them to meet and exceed our customers’ specifications. Along with our 24 hour operation five days a week, we also offer pick up and delivery service within a designated area, allowing us to easily meet tight delivery dates.

Blanchard Grinding Basics

Characteristic of a Vertical Spindle Rotary Surface Grinder is its trademark cross-hatched surface finish, caused by the turning motion of the grinding wheels moving counter to the rotation of the part on the table. Although the machine manufacturer’s name, “Blanchard”, has become synonymous with the process, setting the standard for the industry in general, there are a number of popular vertical spindle rotary grinders: Mattison, Heald, and DCM-Tech among them.

The burly, muscular grinders quickly remove stock from one side of a part using segmented coarsely abrasive stones mounted on a wheel. A flat magnetic chuck, or table, holds magnetic materials such as ferrous metals in place; specially designed fixtures are used to position non-ferrous and non-magnetic materials during the industrial grinding process.

The benefits of vertical spindle rotary industrial grinding is the ability to quickly and efficiently remove large amounts of stock from one side of a part that is usually too large to be double ground. The speed of Blanchard grinding assures quick turn-around with high-production rates and a moderate finish.

CB Manufacturing is your best industrial grinding resource. With over 50 years of experience, our craftsmen can hold the closest tolerances on size, flatness and parallelism. We have several Blanchard Grinders and are experts at using these machines. Blanchard Grinding is a specialty that requires years of experience. We are Southwest Ohio’s leader for performance and quality in Blanchard Grinding.

We operate five CNC grinders with 5-axis movements. If you can draw it, we can grind it! 5-axis grinding allows us to grind many complex shapes that cannot be ground using conventional griniding equipment. CB manufacturing has more CNC industrial grinding equipment than anyone in Dayton Ohio, or the Southwest Ohio.

With several trucks on the road daily, our knowledgeable drivers can transport your parts cost-effectively and safely. We total over 20 major grinding machines in operation 24 hours-per-day, and are ready to meet your delivery needs.

Experience with grinding and machining all types of materials including abrasive plate, stainless steels, tungsten carbide, ceramics, beryllium copper, and others.

We possess all the auxiliary equipment needed such as:

  • 10-ton crane
  • Automatic plate turning machine
  • 168″ granite surface plate
  • CMM measuring equipment
  • Vibratory and sandblasting de-burring systems
  • Blanchard Grinders, up to 108″ Largest in Dayton, Ohio
  • Surface Grinders capable of 204″
  • OD Grinders
  • CNC Milling Machines up 120″ (one of the largest in Southwest Ohio)

We also operate 40 major machines including manual mills, CNC machining centers, NC saws and heat-treating furnaces. We can subcontract machine work or produce from scratch most any wear parts, machine knives, or precision steel specialties.


With the many advances made in hard machining and the changes in machining of tools steels that have occurred over the last few years, CB Manufacturing has made extensive investment in CNC machining capability. We are focused on machining those hard to process metals and this sets us apart from other general purpose subcontract machining sources.

We have 7 CNC machines ranging from 20 X 40 inch capacity up to 40 X 96 and have extensive expertise for machining of tool steels, difficult to process materials and exotic applications. Combined with one of the largest surface grinding facilities in the nation and an extensive heat treat capability right on campus, we offer a one-stop source for many of your machining needs.
