Robotics Precision Gear Racks Machining Capabilities
Perfect tooth geometry and surface durability are supplied by precision gear hobbing, rack shaping, tooth grinding, and induction hardening. Pitch verification and CMM inspection ensure durability of industrial gear racks which are constructed from alloy steels (4140, 8620), tool steels (S7), stainless steels (440C, 17-4 PH), aluminum alloys (7075-T6), and others. Withstanding wear and continuous reciprocating motion in harsh industrial settings is no challenge for our exceptional quality industrial gear racks.

Materials for Precision Gear Racks Components
High machinability and ductility. Aluminum alloys have good strength-to-weight ratio, high thermal and electrical conductivity, low density and natural corrosion resistance.
Stainless steel alloys have high strength, ductility, wear and corrosion resistance. They can be easily welded, machined and polished. The hardness and the cost of stainless steel is higher than that of aluminum alloy.
Titanium is an advanced material with excellent corrosion resistance, biocompatibility, and strength-to-weight characteristics. This unique range of properties makes it an ideal choice for many of the engineering challenges faced by the medical, energy, chemical processing, and aerospace industries.
Steel is a strong, versatile, and durable alloy of iron and carbon. Steel is strong and durable. High tensile strength, corrosion resistance heat and fire resistance, easily molded and formed. Its applications range from construction materials and structural components to automotive and aerospace components.
Highly resistant to seawater corrosion. The material’s mechanical properties are inferior to many other machinable metals, making it best for low-stress components produced by CNC machining.
Few metals have the electric conductivity that copper has when it comes to CNC milling materials. The material’s high corrosion resistance aids in preventing rust, and its thermal conductivity features facilitate CNC machining shaping.
Brass is mechanically stronger and lower-friction metal properties make CNC machining brass ideal for mechanical applications that also require corrosion resistance such as those encountered in the marine industry.
Zinc is a slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed.
Iron is an indispensable metal in the industrial sector. Iron is alloyed with a small amount of carbon – steel, which is not easily demagnetized after magnetization and is an excellent hard magnetic material, as well as an important industrial material, and is also used as the main raw material for artificial magnetism.
Due to the low mechanical strength of pure magnesium, magnesium alloys are mainly used. Magnesium alloy has low density but high strength and good rigidity. Good toughness and strong shock absorption. Low heat capacity, fast solidification speed, and good die-casting performance.

Custom protective coatings and thermal barriers
For gear racks, a precise involute profile allows for smooth rolling contact, which also minimizes friction, noise, and vibration, facilitating quiet operation at speeds in excess of 3 meters per second.
For gear racks, straightness of 0.001 inches per foot over the length of the rack is also critical to prevent binding and uneven loading. This straightness control allows consistent mesh to be maintained throughout the travel length of the rack.
Hardening the rack tooth surfaces to 55-60 HRC increases the rack life to greater than 10 million cycles of continuous operation and engagement.
Achieving DIN 5 quality with precision assembly allows tracking to within 0.01 millimeters. The precision finishing grinding stacked in the straightened and parallel surfaces permits consistent control of mesh depth with desired backlash. Quality machining of power rails and rack and pinion drives ensures reliable linear motion for gantry robots, CNC routers, laser cutters, and automated storage systems.
