Blind hole cutting requires a custom insert. The insert’s composition and hardness are altered to reduce the risk of chipping. Additional design considerations are required for small diameter holes with restricted chip flow, deep hole cutting, and when working with bars of material in lathe operations. The programs used for blind hole cutting require that special attention is given to the end of each stroke and the retraction of the Insert. A straight X axis move out of the work can result in chipping of the insert. Programming assistance is available; the manufacturer, model, and controls of the machine to be used as well as a fully dimensioned drawing of the finished part are required. The proper design, insert material, and programming is essential to success.

Cutting Keyways in a Tapered Bore

Cutting keyways in a tapered bore is made easier on CNC Lathes and Machining Centers as the tapered keyway is cut while the work piece remains within the same co-ordinate system. For burr-free parts, a chamfer feature may be added to the insert. Programing assistance is available.

Cornering Inserts

Machine squares, hexagons, and Octagons with Inserts designed with two cutting edges intersecting at the appropriate angle 90, 120 or 135 degrees. Cut the corner, rotate the spindle (C axis) as required for the next cut (re-run of the subroutine) and repeat to completion.The same cornering inserts may be used to generate a range of sizes of the given shape by simply increasing or decreasing the tool offset.

Internal Toothing & Grooving Inserts

Inserts designed to meet industry standards (ANSI, DIN, ISO etc.) as well as non- standard geometries are available. A chamfering feature may be added in order to produce a burr-free part. One machine processing in the same coordinate system promotes product uniformity and processing efficiencies.
