Chevalier grinding spindle and motorized spindle repair
Brochexpress is an independent workshop specialising in the repair, maintenance and diagnostics of Chevalier (Falcon Machine Tools) spindles and motorized spindles — a Taiwanese manufacturer specialising in precision surface grinders, present in mould-making, medical, aerospace and electric vehicle industries.
Chevalier (Falcon Machine Tools), Taiwanese surface grinding specialist
TLDR: Chevalier (a Falcon Machine Tools brand, Taiwan) is a manufacturer specialising in high-precision surface grinders, with a range covering manual, automatic and CNC machines, aimed at mould-making, medical, aerospace, semiconductor and electric vehicle industries.
Chevalier, a Falcon Machine Tools brand, has built recognised expertise in the design of high-precision surface grinders, with a range covering manual machines (FSG series), automatic machines (FSG-ADIV series, with a travelling-column structure to reduce vibration) and CNC machines (SMART series, FGP series for profiling). The manufacturer has devoted considerable time and effort to the electric vehicle industry, seeking to meet the requirements of mirror grinding, high dimensional accuracy and stability. Chevalier machines also equip demanding sectors such as medical, energy, semiconductor and aerospace, with solutions dedicated to the manufacture of high-quality moulds.
A range of precision cartridge spindles, from manual to high-speed CNC
TLDR: Chevalier grinders feature high-precision cartridge spindles fitted with class 7 angular contact bearings, with rotation speeds ranging from 600 to 10,000 rpm depending on the range and the application (standard surface grinding, high-speed profiling).
Chevalier manual surface grinders (FSG series) feature a high-precision cartridge spindle, fitted with four class 7 angular contact ball bearings, suited to heavy grinding with a guaranteed very low spindle runout. On SMART series CNC grinders, dedicated to the medical, energy, semiconductor, aerospace and mould-making sectors, the spindle can reach 600 to 7,000 rpm for a power of 25 hp. On CNC profiling machines dedicated to high-speed grinding of ultra-hard parts (FGP series), the spindle can run from 2,000 to 10,000 rpm for a power of 3.7 kW, with table acceleration of up to 2.5 G.
