Custom Jaws for Lathe Chucks

Promservice manufactures custom jaws for lathe chucks of leading global brands — ROHM, SMW AUTOBLOK, Samchully, and others. We also produce jaws for manual chucks with an Archimedean spiral, often used in non-standard or specialized equipment.
Our products ensure reliable clamping of workpieces, high precision, and durability in industrial environments. We combine turning experience, modern equipment, and technical expertise to ensure each product meets your specific needs.
We guarantee precise compliance with the original specifications or the customer’s technical requirements.

Jaw Types
Standard (Straight)
Used for external clamping of the workpiece. Ideally suited for machining cylindrical parts with large diameters.
Reverse
Used for internal clamping, when the part is fixed from the inside (e.g., bushings or rings). Provides reliable holding during internal machining.
Combined
A universal solution that combines the capabilities of both standard and reverse jaws. Often used in mixed production or when machining different types of parts on one machine.
Chuck Compatibility
We manufacture jaws compatible with standard and non-standard mounting systems, for various types of lathe chucks, including:
ROHM
SMW AUTOBLOK
Samchully
Manual chucks with Archimedean spiral
Technology & Quality
High-Precision Milling and Grinding
Ensures geometric accuracy and surface finish. Our modern equipment allows high repeatability in series production and perfect fit for custom-made parts.
Heat Treatment for Wear Resistance
Improves the mechanical properties of steel, making jaws more durable and resistant to load and wear under intensive use.
Materials: Alloy, Tool, Structural Steel
We select the steel grade according to the task — from high strength to deformation resistance. Working with high-quality metals guarantees product reliability.
Precision Control of Mounting Surfaces
All critical dimensions are checked at every stage. We ensure that mounting surfaces match chuck parameters, eliminating backlash or misalignment.
Single or Series Production Available
Flexible manufacturing volumes — from a one-off item by individual drawing to a series batch for enterprises. Quick production process adjustment to customer needs.
Lead Time & Delivery
Production: 5 to 12 business days (depending on complexity)
Delivery: across Ukraine and EU countries
Consulting: technical support throughout all cooperation stages
