MicroLab spindle and motor spindle repair
Brochexpress is an independent workshop specialising in the repair, maintenance and diagnostics of MicroLab Precision Technology spindles and motor spindles — a Taiwanese manufacturer established in 1999, specialising in milling spindles, direct-drive mill-turn spindles and multi-axis rotary spindle heads for 5-axis machining.
MicroLab, a Taiwanese specialist in spindles and rotary heads since 1999
TLDR: MicroLab Precision Technology Co., Ltd., established in Taiwan since 1999, manufactures milling spindles for the machine tool industry, with a range covering machining centre spindles, built-in spindles, single and dual A/C rotary spindle heads, direct-drive spindles and belt-driven spindles.
MicroLab Precision Technology Co., Ltd., established in Taiwan since 1999, has built recognised expertise in manufacturing milling spindles for the machine tool industry, with a particularly broad product range: machining centre spindles, built-in spindles, single rotary spindle heads and dual A/C rotary spindle heads, direct-drive spindles, high-speed spindles and belt-driven spindles. The manufacturer claims highly efficient production of spindles and rotary tables, backed by solid experience in science and technology, with products designed to meet international inspection and evaluation standards. MicroLab rotary spindle heads are notably used on 5-axis machining centres and on CNC lathes combining milling and turning, with established applications in aerospace and in the automotive engine industry.
A range of multi-purpose rotary spindles, from ISO25 to #50, up to 30,000 rpm
TLDR: MicroLab rotary spindles cover a wide range of sizes depending on the application — from the #25 spindle (ISO25/HSK32E, up to 30,000 rpm, dedicated to 5-axis centres) through to the #50 spindle (HSK100A), by way of the #30 and #40 sizes — with varied interfaces including BT, ISO, DIN, CAT, HSK and Capto depending on the model.
MicroLab rotary spindles come in several standard sizes according to the intended application. The #25 rotary spindle, models RM25-GMS-T (ISO25 tool holder) and RH3-GMS-T (HSK32E tool holder), delivers high torque and rigidity for free-form surface machining on 5-axis machining centres, with a maximum speed of up to 30,000 rpm. The #30 rotary spindle, available as models RM3-LMSN-T (BT30, ISO30, BBT30 tool holder) and RH4-LMSN-T (optional HSK40T/HSK40A tool holder), targets the same high-torque applications. The #40 rotary spindle, models RM4-HMSC-T and RH6-HMSC-T (optional HSK63A tool holder, oil-hole type), reaches 15,000 rpm with optional braking for mill-turn applications. Direct-drive mill-turn motor spindles, such as the H6-VNTS model with a 120 mm housing diameter, feature a dual contact face tool holder of the Capto or HSK-T type for optimal clamping stability, with a maximum speed of 15,000 rpm in collet version, or HSK63T/Capto63 in tool holder version.
Rotary spindle heads, for 5-axis and multitasking machining
MicroLab rotary spindle heads combine a rotary spindle with a rotary table, for precision and a compact design suited to 5-axis machining centres and CNC lathes combining milling and turning. The #40 head, model RM4-HMSC-T+JEA (BT40, DIN40, CAT40 tool holder, up to 15,000 rpm for the spindle and 30 rpm for the associated rotary table), and its HSK equivalent (RH6-HMSC-T+JEA, HSK63A/HSK63T/CAPTO63 tool holder), are fitted with a high-resolution encoder ensuring high positioning accuracy and repeatability, with announced compatibility with many types of controller according to customer requirements. The #50 head, model RM5-HMSC-T+JEA-WM (#50 and HSK100A tool holder), completes the range for higher-capacity applications.
