Machining Centre, 5-Axis

Gleason has introduced the first product after its alliance with Heller, a 5-axis Machining Centre, the Gleason-Heller CT 8000, for production of all types of bevel gears as large as 1,810 mm in diameter, and pinions to 1,500 mm in length. For the first time ever, gear jobbers will be able to quickly and easily produce design variations, make corrections and machine bevel gears complete, beginning with a forged raw part or a cylindrical blank up to the gear finishing operations in hardened material. Now, single set-up machining in small and medium batches will be an attractive proposition to many users. The CT 8000 draws from the many strengths and capabilities of Heller 5-axis machining centre design for which the company is well known. For example, in order to perform high-torque heavy milling and drilling operations in steel, stainless steel, cast iron and high strength materials, the CT 8000 features a particularly rigid and extremely stable bed and column design of the type proven in Heller’s MCH-C and H series of 5- and 4-axis machining centres. The CT 8000’s extremely rigid C swivel head (the fifth axis), combined with a powerful high torque and high power main gear spindle with HSK-A100 tool taper, is capable of delivering heavy-duty rough cutting (milling, drilling and tapping) at 1,146 Nm – of particular importance for the roughing of the outer shape of the bevel gear from the raw part. The rigid structure and the stiffness of this swivel head also permits the use of the typical uP-Gear cutter with diameters up to 260 mm for roughing the tooth gaps in the soft state and finishing the tooth flanks in the hard.
