Carbon brushes for metal lathe Holzmann ED750FD
Electronic card for Holzmann ED750FD metal lathe
The Holzmann ED750FD is a versatile metal lathe designed for turning, machining and thread-cutting work in small workshops, training centres and environments requiring a compact but robust machine. The current version has a 750 mm distance between centres, a maximum swing over bed of 250 mm, a 25 mm spindle bore and a 230 V motor rated at 750 W S1.
Its spindle speed is divided into two ranges, 50 to 1250 rpm and 100 to 2500 rpm, with variable adjustment by potentiometer and an LCD speed display. Over time, transmission, motor or electronic-control components can wear. This category brings together the spare parts currently offered for the Holzmann ED750FD to support maintenance and repair.
The ED750FD category is deliberately focused. It currently contains four products: a pair of motor carbon brushes, an electronic control board compatible with the Holzmann ED750FD and ED400FD, replacement motor reference 10000351 and a drive belt for the ED750FD. The information on this page therefore concentrates on these genuinely available components and the checks that can help determine which one may be involved in a fault.
The selection may develop according to user requirements and manufacturer availability. If a mechanical component shown in the exploded diagram is not yet listed, its position number is the best starting point when contacting us to identify the corresponding part.
The motor is central to the lathe drive system. Our catalogue offers the 10000351 replacement motor for the Holzmann ED750FD together with a pair of carbon brushes for this model. Carbon brushes are wear parts and should be inspected if the motor becomes difficult to start, cuts out, loses power or runs irregularly.
Before replacing the complete motor, check that the brushes retain sufficient length, move freely in their holders and have a satisfactory contact surface. A power-supply problem, electronic-board fault, transmission issue or mechanical resistance can produce symptoms similar to motor failure. Methodical diagnosis can therefore avoid replacing an expensive component unnecessarily.
The category also contains an electronic control board compatible with the Holzmann ED750FD and ED400FD. On a variable-speed lathe, the electronics participate in motor control and machine operation. Failure to start, unstable speed or abnormal behaviour can justify checking this part of the circuit, but these symptoms alone do not prove that the board is defective.
Before ordering, photograph the original board, its references and connectors. Inspect accessible connections and the general condition of the circuit. Electrical and electronic components require particularly careful identification because incorrect diagnosis or connection can damage a new component.
The drive belt for the Holzmann ED750FD metal lathe transfers movement from the motor to the drive mechanism. Its condition should be checked if slipping, loss of drive, vibration or unusual noise appears. A loose, damaged or worn belt can affect spindle consistency and lathe performance.
Before replacement, inspect belt tension, alignment and visible condition. Keep the original belt until the new one has been received and photograph any markings. During installation, position the belt correctly without excessive tension so that unnecessary loads are not applied to the driven components.
On the ED750FD, one symptom can have several causes. Reduced power may relate to the carbon brushes, motor, electronics or excessive mechanical resistance. Irregular rotation can lead to checks of the belt and drive system, while a speed-control problem requires inspection of the control system and connections before blaming the electronic board.
Start by describing the fault accurately: does the machine start, does the motor rotate, does the speed vary normally, and does the problem occur when cold or after several minutes? Then inspect visible components without randomly changing wiring. Any intervention must be performed with the machine stopped and disconnected from the mains.

The ED750FD has an induction-hardened and precision-ground prism bed, an MT4 spindle taper, an MT2 tailstock taper and a feed gearbox containing gears. The manufacturer also describes an oil-bath-lubricated gearbox. Regular maintenance therefore contributes directly to preserving accuracy, smooth movement and component life.
Remove chips regularly, keep guide surfaces clean and follow the lubrication operations specified in the manual. Monitor new noises, overheating, vibration, play and transmission condition. A clean machine also makes leaks, loose fasteners or abnormal wear easier to detect.
The Holzmann ED750FD manual contains detailed exploded diagrams of the machine, including the feed gearbox and its components. Even when a part is not yet present in our catalogue, the position number shown in the exploded diagram is essential information for identifying a component.
Before dismantling, photograph the identification plate, original component and its location. Record references, dimensions and electrical data when visible. For a part not listed online, provide the ED750FD model, serial number, manufacturing date and exploded-diagram position number.
IMPORTANT: BEFORE PURCHASING, carefully check the list of compatible machines shown on each product page.
For some replacement parts, the machine model alone is not sufficient to guarantee compatibility. Depending on manufacturer changes, the same model may have been fitted with different components during its production life.
If you are unsure, please provide the exact model, month and year of manufacture, and serial number of your machine before ordering.
Probois Machinoutils offers parts for several Holzmann metal lathes, including the ED300ECO, ED300FD, ED400FD and ED750FD. For the ED750FD, our current offer focuses on the motor, carbon brushes, drive belt and electronic control board, with the range able to evolve according to requirements and part availability.
Our aim is to help you repair and extend the service life of your Holzmann ED750FD. Correctly identifying the cause of a fault and the component reference often makes it possible to replace only the necessary part and keep a perfectly serviceable machine in use.
