Horizontal Machining Center Designed for Hard Metals
IMTS 2018: The HMC 800 from Fives Cincinnati is designed for aerospace, oil and gas, and other hard-metal precision machining applications.
The HMC 800 from Fives Cincinnati suits aerospace, oil and gas, and other hard-metal precision machining applications. It combines high spindle torque with machine stiffness. Its dual ball screws enable feed rates of 45 m/min, with acceleration and deceleration rates of 0.5 G.
The bridge and saddle are said to feature enhanced dynamic stiffness for quality finish and extended tool life. Designed for complex five-axis and five-sided applications,,the machine combines twin ball-screw-driven axes in XYZ, an infinite contouring B-axis table, and a compact, U-frame A-axis tilt spindle.
High-torque spindle options, including two offering 6,000 rpm, enable processing hard metal processing. Spindles offer external flood with pressure ranging to 250 psi and internal through-spindle coolant with pressure ranging to 1,500 psi (HSK100A/KM4X). Tooling options include HSK-100A, KM4X100 and Big plus 50.
Producing fine finishes on EDMed surfaces has long been a goal, especially for mold and die shops that operate ram-type electrical discharge machines. Lately, there has been renewed interest in using additives in the dielectric oil to achieve ultra fine finishes with graphite electrodes without excessive burn times.
Moving on oil can let a grinding machine deliver more power along a smoother pass.
CAMCO, a Schlumberger Company (Houston, Texas), is a manufacturer of oil field components consisting of packers and safety valves. Due to the size of the parts, the company recently replaced many of its manual lathes with Weiler manual/CNC flat bed lathes.
