Machining of castings | Support for cast products from other companies, accommodating high precision tolerances with unique know-how.
AC4CH/AC4B/CAC406/Compatible with the materials of other companies' cast products in general.
We were unable to provide tolerances for other companies' castings and were refused processing. With our unique know-how that takes into account the variability of casting shrinkage, we can also accommodate high-precision tolerances for semiconductor components.
Have you ever experienced being turned down for machining because you brought in castings from another company that couldn't meet the tolerances? The more precise the tolerances required for shapes, such as parts for semiconductor manufacturing equipment, the fewer machining options are available. With castings from other companies, it is difficult to grasp the variations in shrinkage and internal stress for each casting, and know-how is required to machine them while guaranteeing tolerances. If the assessment is incorrect, dimensions may deviate during the machining process. Karmo Casting conducts its own casting, allowing for the estimation of machining conditions based on the tendencies of shrinkage and distortion of the castings. By using a contact-type three-dimensional measuring machine and a non-contact digitizer to check dimensions during and after machining, we can achieve high-precision tolerances even for castings from other companies. This product is an example of finishing a different part for semiconductor manufacturing equipment to meet tolerances using our unique know-how from castings produced by another company. We are offering a technical document summarizing the break-even point by method and considerations for small lot production for free. Please download it from the link below.

Price information
If you provide the drawings and the castings (actual items), we will give you a free estimate. We also accept high-tolerance machining requests for cast products from other companies, regardless of material or casting method. Since we can handle everything from our own casting to machining, we can also propose remaking castings that are difficult to achieve tolerances for.
