Stace-Allen Chucks

What Stace-Allen Chucks does

Stace-Allen Chucks, Inc. is a privately held, family-owned manufacturer founded in 1946 in Indianapolis, Indiana, specializing in custom-engineered workholding solutions. The company designs and builds power chucks, precision chucks, collet chucks, and fixtures to customer-specific specifications for CNC machining, lathe, milling, and grinding operations. Its product portfolio spans multiple named series across the power and precision chuck lines, plus custom collet chuck configurations (internal/external gripping, ID/OD machining, various actuation methods, and high-RPM applications) and a range of fixtures including swing clamps, pneumatic clamps, work supports, and continuous closed-loop systems. A proprietary Bubble Collet design — featuring a bubble-shaped web that grips diameters at two points — is a notable technical differentiator, alongside a virtual test environment used to simulate prototype performance before physical build and field testing at customer sites.

The company serves primarily automotive, aerospace, and machine builder/distributor customers, with additional work in medical device and general manufacturing. GTM is consultative and sales-led: customers initiate contact for quotes, and engagements follow a five-step process of specifications gathering, solution concept and quote, design and customization, prototype and testing, and iterative deployment. Revenue is generated through one-time custom product orders and associated engineering/design services, with pricing quote-based and not publicly disclosed. The firm has operated continuously under family ownership for three generations — currently led by President Philip Grimes, grandson of co-founder Joseph S. Allen — and has expanded from local Midwest manufacturers to a global customer base, with key personnel including a Vice President, Lead Engineer, and Senior Machinist supporting the operation from the original Indianapolis headquarters.

Products and services

• Power Chucks High-speed, precision power chucks designed for volume production applications, with custom configurations including R1200, R1600 & R4600, R2200, R4200, and R4400 series in various diameters. Built for removing large amounts of material while maintaining accuracy, intended for manufacturing customers requiring dependable workholding in high-volume CNC machining.
• Precision Chucks Lightweight precision chucks engineered for tight tolerance applications where weight and space are limited. Featuring proprietary jaw mounting processes and specialty designs, available in 10, 20, 30 & 40, 80, 90, and 25M, 55D & 93D series for aerospace and precision manufacturing customers.
• Collet Chucks Custom collet chucks optimized for grinding fragile or oddly sized parts and for machining thin-walled parts in high-RPM applications. Configurations include internal/external gripping, ID and OD machining, air/hydraulic/drawbar actuation, and integration with proprietary bubble collets that hold long parts in a single stage while keeping diameters concentric.
• Fixtures Custom workholding fixtures including swing clamps, pneumatic clamps, work supports, pallet clamps, subplates, tombstone/pallet loading systems, and continuous closed-loop systems. Designed to improve machining, milling, and drilling operations for manufacturing customers.
