WEISS spindle assemblies for machine tools
Source WEISS spindle assemblies and associated components against nameplates, drawings and machine requirements. Define the version and scope for a technical quotation.
WEISS 2SP1 milling motor spindles
The manufacturer describes 2SP1 as a standard milling motor-spindle family. A selection request should identify the spindle version, tool interface and release arrangement.
- 2SP1 family and ECO version
- Hydraulic or pneumatic release
- HSK A63 interface described for the family
WEISS 2SP2 asynchronous milling spindles
WEISS describes 2SP2 as an asynchronous milling-spindle family. Speed capability depends on the bearing lubrication version and must be checked for the selected assembly.
- Up to 20,000 rpm with lifetime grease lubrication
- Up to 24,000 rpm with oil-air lubrication
- Open or closed cooling-jacket options
WEISS turning spindles
The turning portfolio includes externally driven spindle units and motor spindles. Replacement selection starts with the spindle nose, mounting dimensions, drive arrangement and lubrication system.
- External drive, including belt drive
- Integrated synchronous or asynchronous motor
- Different lubrication arrangements
WEISS grinding and dressing spindles
The manufacturer lists spindle units for internal cylindrical grinding, external cylindrical grinding and dressing. The request should state the machining operation and wheel or dressing-tool mounting.
- Internal cylindrical grinding
- External cylindrical grinding
- Dressing spindle applications
WEISS spindles with an integrated B axis
WEISS combines milling or milling-turning spindles with a B axis. Selection concerns the complete assembly, including its rotary section and machine connection.
- Milling or milling-turning spindle
- Integrated B axis
- Assembly layout checked against machine documents
WEISS SiS+ clamping and chip monitoring
According to the manufacturer, SiS+ detects chips at the spindle interface and monitors clamping force for HSK A63 tooling. Component selection requires the installed system designation.
- HSK A63 interface monitoring
- Checks after tool changes
- Tool clamping-force monitoring
Identify the installed spindle assembly
Start with a readable photograph of the spindle nameplate, the machine model and the assembly drawing. Keep the complete designation, including suffixes and separators. If the machine documentation uses a different reference, supply both references and identify their sources.
A family name such as 2SP1 helps route the inquiry, while the complete assembly code identifies the version to be checked.
For an existing machine, include the relevant parts-list page and any previous replacement specification. If the nameplate is inaccessible, send the available documents and identify the missing fields. Photographs should show the complete label and the surrounding installation.
Do not dismantle equipment solely to obtain a picture without following the machine procedure.
Define the equipment requirement
For a new machine or a retrofit, describe the machining operation, workpiece material, operating cycle and installation constraints. State which requirements are fixed by the machine designer and which can be discussed.
Supply the proposed layout, available mounting space and the required tool interface. A structured specification makes it possible to compare spindle versions against the same requirements.
Separate continuous operating requirements from occasional conditions. Record the source of each figure and identify assumptions that still need engineering approval.
Selection for a project concerns the complete configuration, including mechanical connections, electrical interfaces and auxiliary services. The responsible machine engineering team approves integration; the supply quotation follows the configuration agreed for that project.
Check mechanical interfaces
Provide a dimensioned drawing showing the mounting flange, spindle nose or tool interface, and the connection positions. For turning applications, identify the spindle nose and the attached workholding arrangement. For grinding applications, identify the wheel or dressing-tool mounting.
A photograph helps explain the layout but does not establish a dimensional match.
When requesting a spindle with an integrated B axis, include the complete assembly installation rather than a cropped view of the spindle cartridge. State whether the request concerns the spindle alone, the rotary unit or the combined assembly.
The boundary of supply should remain explicit throughout technical clarification and quotation.
Motor, feedback and connection documents
If the request concerns a motor, sensor or cable assembly, supply that component designation together with the parent spindle code. Include the electrical diagram and connector schedule where available.
For a complete spindle replacement, identify the existing drive and the machine configuration documents. Clear connector photographs can support identification without replacing the wiring documentation.
Mark whether a component is required with its cable, connectors or mounting accessories. Leave unknown characteristics as questions for clarification. The selection process does not authorize changing drive parameters or protective circuits.
Installation and commissioning remain subject to the machine instructions and the engineering approval appropriate to the equipment.
Cooling and lubrication information
Supply the connection diagram and the cooling or lubrication specification for the actual spindle. Identify the installed version and the services already available on the machine. For a rotary union or a sealing component, include its own marking and its position in the assembly drawing.
This distinguishes the requested item from the complete spindle unit.
The published 2SP2 speed limits refer to different lubrication versions. Keep the selected version and its operating specification together when comparing assemblies. A change of cooling or lubrication arrangement is a separate engineering decision.
Record that decision in the project documents before the final supply configuration is agreed.
Prepare an inquiry after a machine fault
Describe the observed symptom and attach any existing diagnostic report. Include the alarm message, machine identification and the conditions in which the issue occurs. State whether you need a specified component, a replacement spindle assembly or a comparison of technically approved alternatives.
A symptom alone does not identify the required parts.
The equipment specialist determines the diagnosis and the list of affected positions. We use that information for identification and quotation. Disassembly, balancing, clamping-force measurement and return to operation follow the machine procedure.
A parts list from a similar machine should be treated as a reference to investigate rather than a confirmed requirement for this unit.
Specify the boundary of supply
List the main assembly, separate components and accessories as individual positions. Give the designation, quantity and supporting document for each line. If a complete spindle is requested, explicitly identify the items expected to accompany it.
This makes technical and commercial comparisons meaningful and reveals connection items that need separate clarification.
For several machines, keep the quantities linked to each installation. When sending documents, include the pages needed to identify the equipment and omit unrelated confidential material. If a specification changes, state which lines changed and provide the current revision.
The quotation should retain the agreed references instead of replacing them with a general family name.
From inquiry to a technical quotation
Send the spindle designation, the requested scope and a contact for clarification. We first check the identity of the assembly and the available documents. Missing information is requested as a specific field, such as a designation suffix or a drawing position.
The inquiry then records the selected configuration, quantities and technical attachments.
A request may concern one component, a spindle assembly or a project set. State the delivery destination and any documentation requirements. Positions that remain unidentified are recorded separately so that confirmed items keep their exact references.
The agreed specification is the basis for the quotation and for the subsequent comparison of the supplied assembly.
Plan receiving and installation
For transport planning, provide the destination, receiving arrangements and any known weight or dimensions from the equipment documents. Identify handling restrictions and the required packaging scope.
Where the order covers several machine installations, keep the sets clearly separated in the packing specification. The receiving team should have the agreed item list before the assembly arrives.
At receipt, compare the visible marking and package contents with the agreed documents. Retain the equipment identification and the accepted specification for later maintenance inquiries.
Connection, commissioning and acceptance checks are performed by the responsible technical team under the machine procedure. These steps belong in the project plan alongside the supply of the spindle equipment.
