One of the most challenging projects that a manufacturing engineer may ever face is the production of a workpiece that contains a deep hole (up to 100X the bore diameter) with tight surface finish, runout and concentricity requirements. However, this job will pale by comparison to a similar job that also requires a special form at the bottom of the bore! Such forms are commonly used when manufacturing aircraft landing gear, armaments and nuclear components.
American Heller Corporation has be designing and manufacturing deep hole drilling tools for over 40 years and we have the expertize to solve your specialized drilling problems. We have solved hundreds of deep hole drilling problems that would normally cause production costs to skyrocket and delivery times to increase. American Heller can even design a specialized form tool that will combine 2 or more operations.
Consider these unique advantages of American Heller's BTA Form Tools.
- Reduced production time -- fewer operations required to produce the complex form
- Reduced production costs -- finishing processes such as honing are not required to 'clean up' the bore.
- Hole tolerance of ±.001" obtainable.
- Concentricity requirements of ±.0005" obtainable.
- Surface finish of 32-63 Microinchs obtainable.
- Runout of .001" per foot obtainable.
Note: Hole tolerances, concentricity, surface finish and runout will be affected by a number of factors including machine condition, alignment, boring bar straightness, bushing size, etc.
