- ✓Advanced lathes feature a 42″ swing & can clear the cross slide on top of the carriage for diameters up to 24″
- ✓Typical production runs range from 5 to 100 pieces, we’re also fully equipped for high volume production runs
Certifications & Quality
As an AS9100D / ISO9001:2015 certified organization, we pride ourselves in supporting large OEMs with disciplined quality control processes in order to ensure the best work possible. We strive to serve our customers with distinction and act as a long term partner for companies in the aerospace, military, agriculture, oil & gas, power generation, and semiconductor industries.
We are capable of CNC turning a diverse range of materials including:
- Cast Iron
- Stainless Steel
- Carbon Steel
- Alloy Steels
- Nickel Superalloys (Inconel)
- High Temperature Superalloys (Waspaloy)
CNC Turning Equipment
Our equipment is primarily manufactured by Okuma and includes thirteen 2-axis and 4-axis horizontal CNC lathes. Our four machining centers provide highly precise horizontal and vertical operations for milling and drilling. We can perform CNC OD grinding as well as manual grinding using any one of our several models that boast top of the line controls, drives, and spindles.
Besides our large diameter CNC turning capabilities, we offer in-house secondary services that include honing, thread forming, cylindrical grinding, and phosphating. Our carefully vetted, highly reliable outsource partners can assist with thermal spray coating, flame hardening, Blanchard grinding, heat treating, ion or salt nitriding, carburizing, stress relieving, and induction hardening. For threading operations, we’ll meet virtually any customer specified tolerance requirements. Our services are turnkey and we take the lead in all raw materials purchasing, machining, shipping, and subcontracting for an array of projects.
Introducing innovative tools to reduce costs
The client required production of large quantities of a high volume Inconel tubes made from Inconel bar.
The Inconel bar stock is very hard and extremely challenging to drill using high quantities of expensive drilling inserts.
With our extensive experience machining hard and heat resistant materials paired with knowledge from one of our leading tooling providers, we were able to test and implement an innovative coated insert that reduced tool wear with increased Inconel machining performance.
