Workholding for your equipment
Lathe chuck jaw manufacturing
We manufacture jaws from drawings or samples to replace worn sets or hold new parts. From a single set to a batch, with mounting interfaces and gripping geometry agreed for your chuck.
From drawings or samples
Work from existing documentation or reproduce the geometry of an available jaw.
From a single set
Individual orders and production batches.
For your specific chuck
We check the model, mounting surfaces and fastening method.
Jaws for your clamping arrangement
The design depends on the workpiece, diameter range and machining conditions.
Straight jaws
For typical external clamping of shafts, bars and cylindrical blanks.
Reverse jaws
For a different diameter range and clamping arrangement. External or internal clamping capability depends on the design.
Combination jaws
With working surfaces for several clamping arrangements within an agreed range.
Special jaws
With custom profiles, steps or support surfaces for a specific workpiece.
Compatibility with your chuck
We consider jaws for RÖHM, SMW AUTOBLOK, Samchully and other manufacturers based on the specifications of the particular model.
- RÖHM
- SMW AUTOBLOK
- Samchully
Also for manually operated scroll chucks
These are compatible jaws manufactured by us, rather than original parts from the named brands. Mounting, engagement and fastening details are agreed separately for each order.
Examples of manufactured jaws

From mounting geometry to a finished set
The manufacturing sequence depends on the jaw design, material and agreed specifications.
Manufactured in our own facility
We machine the gripping and mounting surfaces with their interaction with the chuck and workpiece in mind.
- Milling profiles, grooves and guide surfaces
- Machining holes and fastening features
- Grinding critical surfaces as specified in the drawing
- Checking dimensions and geometry before delivery
Material
We select the material grade or use the specified grade, taking loads and gripping surfaces into account.
Heat treatment
The need for treatment, process and hardness are agreed for the operating conditions.
Inspection
We check mounting dimensions, fastening features and gripping profiles against the agreed documentation.
What information do we need?
Show the overall geometry, mounting interfaces and fastening features. This guide helps you prepare photographs or drawings for your enquiry.
Select a number on the model or an item in the list to highlight the relevant area.
Key areas of the jaw
Overall dimensions L / B / H
Jaw length, width and height. Mark the dimensions on a drawing or photograph.
Missing some dimensions?
Start with the chuck manufacturer, model and photographs of the jaws. We will identify any further measurements or sample needed.
Close-up photo of the teeth
The tooth pitch and shape should be clearly visible. Add a drawing or measurements of the mounting interfaces if you have them.
Cross-sectional profile
Show the shape, width and depth of grooves and guide surfaces.
An example design is shown. The required parameters depend on your chuck. For the gripping surfaces, include the clamping arrangement and workpiece diameter range.
From enquiry to delivery
Start with the information you have. We agree specifications, price and lead time before manufacturing.
Enquiry and inputs
Provide the chuck model, drawings, photographs or details of a sample, and the required number of sets.
Design review
We clarify mounting, gripping profile, material, heat treatment and inspection requirements.
Quotation
We calculate price and lead time based on complexity, quantity and the agreed scope.
Manufacturing and inspection
We machine the jaws and check dimensions against the agreed specifications.
Handover
We agree how you will collect or receive the finished jaws.
Frequently asked questions
Can I order jaws without a drawing?
Yes, we can consider manufacturing from a sample. Start by sending the chuck model and photographs of the jaws. After review, we will confirm whether more measurements or a physical sample are needed.
Which chucks can you manufacture jaws for?
We consider RÖHM, SMW AUTOBLOK, Samchully, manual scroll chucks and other models. Compatibility is confirmed using the mounting surfaces, engagement and fastening details of the specific chuck. The jaws are manufactured by us and are not original branded parts.
Can I order a single set?
Yes, we accept enquiries from a single set. We also manufacture batches; quantity affects the price and lead time.
Can you manufacture jaws with custom geometry?
Yes, we can consider custom gripping profiles, steps and support features for your workpiece. Please provide a workpiece drawing, clamping arrangement and machining conditions for assessment.
Will new jaws eliminate chuck runout?
Not necessarily. Runout may be caused by chuck condition, worn guides or mechanisms, contamination, mounting or workpiece geometry. New jaws alone do not guarantee that these causes will be eliminated.
What is the manufacturing lead time?
We determine the lead time after reviewing the documentation or sample. It depends on complexity, quantity, material, heat treatment and current production capacity. We agree it in the quotation.
What determines the price?
Jaw design and size, number of sets, material, heat treatment, accuracy and the amount of documentation work required. Send your inputs so we can quote for your order.
Let’s discuss your chuck jaws
Send a drawing or photographs, or briefly describe the job. We will clarify the inputs and prepare a quotation.
