Precision Grinding: Internal, External, Surface

We offer high-quality surface grinding, internal grinding and cylindrical (ID/OD) grinding services. Our grinding services can achieve required dimensional accuracies and surface finishes for demanding applications.

We are equipped with five surface grinding machines that can accommodate parts with flat surfaces in sizes of up to 24 x 60 x 20 inches and can grind surfaces to tight tolerances of about 0.00005 inch. Also we perform grinding operations on other metal forms, including angles and slots.

Our internal grinding capabilities allow us to grind parts with inner diameters of up to 18 inches and lengths of up to 14 inches. The tolerance offered by this service is close to 0.0002 inch, making it ideal for components requiring precision ground IDs, such as hydraulic cylinders and bearings. For example, we have previously ground bearing block diameters to 0.0002 inch to accurately mate it with precision ground bearings.

We also offer cylindrical grinding services for grinding external surfaces of cylindrical components. We are equipped with two center-type cylindrical grinding machines, which can accommodate components that measure up to 75 inches in length and 14 inches in diameter.

Wire EDM

Allis Tool & Machine offers precision wire EDM services. Our specialization lies in the production of large, heavy, and complex components in volumes of about 1 to 300. We employ a state-of-the-art 4-axis Mitsubishi wire EDM machine with an integrated automatic wire threader system to reduce setup time and, in turn, production time. This Wire EDM machine can accommodate parts weighing up to 1,764 lbs (for example) and produce accurate components, with tolerances of +/- 0.0002 inch. While our service is ideal for prototype production, small volume production runs and hard metal components shaping are easily managed by this machine too.

Allis Tool & Machine's wire EDM services are used in the manufacturing of components, such as progressive dies, mold details, and other metal stamping dies, which require accurate machining. The accuracy of wire EDM machines and the resulting cost effective small volume production runs have attracted many industries towards our wire EDM services, gradually replacing our broaching operations.

We are staffed with certified journeymen toolmakers and machinists, who have the experience and skill needed to program and produce your components accurately. Our inspection team ensures the quality of our EDM services with the help of a coordinate measuring machine (CMM). CMM inspections are performed
by full-time inspectors as part of the first part inspection process. Our wire EDM services are used for die modifications and repairs as well.
