In one case, Weyburn-Bartel, Grand Haven, MI, purchased five of the turn, broach-turn machines to produce camshafts
from bar stock for a major US automaker.
For volume production of camshafts
, crankshafts, and gear shafts, the machine has a working range of 300 mm between centers and a center height of 175 mm.
Also, the camshafts
feature new saddle-type caps for improved durability.
Now the company has launched a DLC coating called "Dylyn Plus" to reduce friction and increase the wear resistance for the camshafts
of high-volume production engines.
Featuring a menu-driven sequence builder utility for developing measurement sequences for new crankshafts and camshafts
, this operating system includes advanced utilities for simplifying cam rise data entry.
name Quanex (NYSE:NX) Hoover's states that NX's vehicular products unit makes a variety of seamless steel bars used by original equipment manufacturers (OEMs) to manufacture camshafts
, transmission gears, and bearing cages and rollers.
This sophisticated 16-valve powerplant employs an aluminum cylinder head that features dual overhead camshafts
(DOHC) and Continuously Variable Valve Timing (CVVT).
have only been able to open the valves at a fixed point, defined during engine design and manufacture.
Further, not only does this system eliminate the camshafts
, drive chains/belts, cam phasers, and drive gears/pulleys, it also eliminates their rotational mass, parasitic losses, and cost.
However, with the older Schaudt grinders, it was assumed that the wear caused by producing several million camshafts
had increased the machines' critical tolerances.
The evaluation engines were fully disassembled and all major components - from the crankshaft to camshafts
, from the EGR subsystem to the power cylinder - were analyzed.
Applications include camshafts
, finger followers, finger shafts, gudgeon pins, pistons, tappets and valves, plus clutches, brakes and the inner tubes of a racing bike shock absorber.
