How does a PCD reamer with guide bars handle the stepped holes in the reducer housing?

The housing components of the precision reducer provide an integrated foundation for support and positioning, sealing and lubrication, heat dissipation and vibration damping, as well as protection and load-bearing capabilities, ensuring smooth transmission, oil leakage prevention, and extended service life.

The internal stepped bearing holes precisely position the gears, drive shaft, and bearings, ensuring coaxiality and parallelism of all shaft systems while securing the gear meshing alignment to prevent load imbalance, tooth impact, and high-speed noise. External flanges and mounting holes secure the entire unit to the motor, vehicle frame, or equipment chassis.

Xinruizhi Precision has developed specialized machining solutions for various guide bar tools to address the challenges in processing stepped holes and cross-cut holes in aluminum alloy housings, including applications for gray cast iron and ductile cast iron.

Core Pain Point

➤ Aperture tolerance H7; coaxial deviation for stepped holes: 0.01 mm;

➤ Aluminum materials require a high roughness value of Ra 0.6 to Ra 1.0;

➤ Reduce burr formation at cross holes;

➤ The precision of blade adjustment is difficult and requires frequent adjustments.

Solution: Use a hinge instead of a boring tool.

Cutting Parameters:

Vc=250m/min

Fz=0.1mm/z

Core advantages of Xinxuizhi Precision's wire guiding blades:

➤ The guide bar supports cutting operations, ensures stable coaxiality across multiple steps, and completely resolves high-speed noise issues in the reducer.

➤ The PCD diamond blade resists aluminum adhesion, with a highly polished inner bore ensuring complete oil-proof sealing of the housing.

➤ Stable cross-hole cutting with effective burr suppression and simplified post-processing procedures

➤ Single-blade operation with dual-stage molding, reducing processing steps by half and increasing production capacity by 35%-50%.

➤ A single tool adjustment enables mass production, compensating for the micrometer-level precision deviations of optical tool-setting instruments and offering easy operation.

➤ Replace costly precision boring with milling, compatible with automated mass production linesSpecifically designed for precision hole machining applications in new energy motor reducers, automotive transmissions, and servo aluminum housings.
