Discover our selection of spare parts for Holzmann metal lathes, designed for the maintenance, troubleshooting and repair of your machine.

A metal lathe is a precision machine whose correct operation depends on numerous mechanical, electrical and electronic components. The transmission, spindle, motor, belts, bearings, gears, speed controls, carriages and electrical systems must all operate correctly to ensure smooth workpiece rotation and maintain the accuracy required for turning operations.

Probois Machinoutils offers a growing range of replacement parts for Holzmann metal lathes, including parts for models such as the ED300ECO, ED300FD, ED400FD and ED750FD, depending on available references.

Drive Belts for Holzmann Metal Lathes

The drive belt transfers power between the motor and the different drive components of the lathe.

Over time, a belt may stretch, crack, wear or lose its teeth in the case of a toothed belt.

A defective belt can cause jerking, slipping, loss of power or irregular spindle rotation.

On some Holzmann metal lathes, different belt references may exist depending on the machine version. It is therefore essential to check the reference and dimensions of the original belt before ordering a replacement.

Motors for Holzmann Metal Lathes

The motor is one of the main components of a metal lathe, providing the power required to drive the spindle.

However, loss of power or failure to start does not necessarily mean that the motor itself is defective.

Before replacing the motor, check the electrical supply, carbon brushes where fitted, switches, electronic control board, potentiometer or speed controller, safety devices and mechanical transmission.

An excessively tight belt, seized bearing or transmission mechanism with excessive resistance can also overload the motor.

Motor Carbon Brushes and Brush Holders

Some motors fitted to Holzmann metal lathes use carbon brushes.

These components are naturally subject to wear. When they become too short or wear unevenly, they can cause starting problems, loss of power, irregular operation or excessive sparking from the motor.

When replacing the carbon brushes, it is also advisable to inspect the brush holders and the general condition of the motor.

Replacement brushes must have the correct dimensions and specifications for the relevant motor.

Electronic Control Boards for Holzmann Metal Lathes

Metal lathes equipped with electronic speed adjustment may use an electronic control board to manage motor operation and spindle speed.

A defective control board can cause various symptoms, including failure to start, inability to adjust the speed, irregular motor operation or unexpected machine shutdown.

However, these symptoms do not necessarily mean that the electronic board is faulty.

Before replacing it, check the electrical supply, connections, motor, carbon brushes, potentiometer, switches and other components in the control circuit.

Potentiometers and Speed Control

The potentiometer allows the operator to adjust the spindle speed on metal lathes equipped with electronic variable speed control.

A worn or defective potentiometer can cause irregular speed variations, interruptions or difficulty adjusting the speed correctly.

Before replacing this component, make sure that the fault is not caused by the electronic control board or another electrical component.

The reference marked on the original potentiometer is particularly important when identifying a compatible replacement.

Speed Selectors and Controls

Depending on their design, Holzmann metal lathes may use different speed selectors, controls and speed adjustment systems.

These components allow the operator to select or modify the spindle operating speed.

A defective selector may prevent the machine from starting, changing speed or operating normally.

As with any electrical or electronic component, the exact reference and compatibility with the specific machine version must be checked before ordering.

Gears and Pinions for Holzmann Metal Lathes

Gears and pinions are essential to many lathe mechanisms, particularly the transmission, power feed and thread-cutting systems.

A broken tooth or heavily worn gear can cause knocking noises, irregular drive, excessive backlash or prevent certain machine functions from operating.

Before replacing a gear, it is advisable to inspect the other gears with which it operates.

A damaged gear may be the consequence of a blockage, incorrect adjustment or failure of another transmission component.

Spindles and Spindle Components

The spindle is one of the most important components affecting the accuracy of a metal lathe. It provides the rotation required to drive the chuck and workpiece.

Excessive play, vibration or unusual noise from the spindle area can directly affect machining quality.

However, a spindle problem may also be caused by its bearings, transmission, pulleys, gears or chuck mounting system.

A complete diagnosis is therefore recommended before replacing a major spindle component.

Bearings for Holzmann Metal Lathes

Bearings allow various mechanical components of the lathe to rotate while reducing friction.

A worn bearing can cause noise, vibration, overheating or excessive mechanical play.

On a metal lathe, excessive play in a spindle bearing can directly affect machining accuracy and surface finish.

Before ordering a bearing, check its reference, dimensions and exact position on the machine's exploded parts diagram.

Chucks and Workholding Components

The lathe chuck securely holds the workpiece during machining. Different types of chucks may be used depending on the lathe and the required operation.

Chuck jaws, clamping systems, mounting plates and fastening components must remain in good condition to hold the workpiece securely.

When replacing a chuck or mounting component, it is essential to check its diameter, mounting type, fastening system and compatibility with the lathe spindle.

Carriages, Lead Screws and Feed Mechanisms

Precise movement of the cutting tool relies on several mechanisms, including the carriage, cross slide, compound slide, lead screws, nuts, handwheels, cranks, shafts and locking mechanisms.

Wear in these components can cause excessive backlash and reduce adjustment accuracy.

When excessive play develops, its exact source should be identified before replacing a component. The problem may come from a lead screw, nut, gib adjustment or another part of the mechanism.

Handwheels, Handles and Levers

Handwheels, handles, cranks and levers are used to control the different movements and adjustments of a metal lathe.

They can become damaged following an impact, excessive tightening or prolonged use.

Even when a component appears simple, it is important to check its diameter, bore, mounting system and position number.

Different versions of the same Holzmann lathe may use different handwheels or handles depending on the production period.

Tailstock and Adjustment Parts

The tailstock is used to support long workpieces and can also hold drilling, centring and other tooling.

Its mechanism contains several components that may wear over time, including the quill, screw, handwheel, locking systems and adjustment parts.

Excessive play or difficult movement should be investigated to accurately identify the component responsible for the problem.

Switches and Electrical Components

Switches, emergency stop buttons, contactors, safety devices and other electrical components contribute to the operation and protection of the metal lathe.

A machine that no longer starts does not necessarily have a defective switch.

Before replacing an electrical component, check the power supply, safety devices, wiring, motor and, depending on the model, the carbon brushes, electronic control board and variable speed system.

The electrical specifications of the replacement component must always match those of the machine.

How to Find the Correct Part for Your Holzmann Metal Lathe

To correctly identify a spare part for a Holzmann metal lathe, first check the exact model indicated on the machine identification plate.

Then consult the exploded parts diagram corresponding precisely to your lathe to determine the position number of the required component.

Several details may be required to correctly identify a replacement part: exact model, position number, month and year of manufacture, serial number, supply voltage and any reference marked on the original component.

For certain components such as belts, bearings, gears, pulleys, motors, handwheels or shafts, it may also be necessary to check their exact dimensions.

IMPORTANT: Check Compatibility Before Ordering

IMPORTANT: BEFORE ORDERING, ALWAYS CHECK THE LIST OF COMPATIBLE MACHINES PROVIDED ON THE PRODUCT PAGE.

Holzmann may have modified certain components during the production period of the same metal lathe model.

As a result, two machines with the same commercial model reference may use different components depending on their month and year of manufacture or serial number.

This check is particularly important for motors, belts, electronic control boards, potentiometers, switches, gears, handwheels and other electrical or mechanical components.

Never order a replacement part solely because it looks similar to the component fitted to your machine.

Using the Exploded Parts Diagram for Your Holzmann Metal Lathe

The exploded parts diagram for your Holzmann metal lathe is one of the most reliable ways to identify a replacement part.

Locate the technical documentation corresponding exactly to the model and generation of your machine, then identify the required component.

The position number can then be used to identify the corresponding spare part reference more accurately.

If several versions of the component exist, the information on the machine identification plate, together with the dimensions and markings on the original component, can help confirm the correct replacement.

Maintaining and Repairing a Holzmann Metal Lathe

Regular maintenance helps preserve the accuracy and service life of a metal lathe.

Regularly inspect the belts, gears, bearings, spindle, carriages, lead screws, clamping systems and electrical components.

Metal chips should be regularly removed from the slides and mechanisms. Guide surfaces and components requiring lubrication should also be maintained according to the machine's maintenance instructions.

Unusual noise, vibration, mechanical play, loss of power or abnormal speed variations should be investigated promptly to prevent an initial fault from damaging additional components.
