1.What is CNC machining?

CNC (Consumer Numerical Control) milling and machining is a process in which high tech software creates parts or components for manufacturing. These parts tend to be more accurate and of higher quality than if they were produced using other manufacturing methods. As a result, CNC machined parts are used in industries which rely on absolute accuracy, including aerospace and auto production. The CNC machines used by PTJ Shop & Manufacturing are capable of delivering smaller, delicate components.learn our Turning&Milling case studies.

2.Which industries benefit from CNC machining??

Many industries benefit from CNC machining, though they are far more necessary in some fields than others. Different CNC machines are capable of different levels of detail during production. For the aerospace/auto/bike/Medical industry, this is essential to their highly specified design plans. There is no room for error when launching a rocket or flying a plan, and CNC machined components from PTJ Factory are made to be as precise as possible.

3.What types of CNC machining are there?

Capabilities include CNC machining, lathe work, turning, shearing, sawing, forming, punching, milling, drilling, reaming, tapping, routing, broaching and screw machining. Parts such as precision parts, molded parts and components can be machined and fabricated. Reverse engineering, deburring, sanding, buffing, glue laminating, insert installation and assembly services are also available. If you are not sure which method would be best for your parts, just ask our experienced technicians and we will happily assist you.Click Online Quote >>>

4.What type of materials do you process?

Average is difficult to define given the diverse nature of materials and processes utilized at PTJ. We consider ourselves as a "Quick Turn&Milling" operation. Often providing much shorter lead times than typical industrial cutting or machining operations. Additionally giving the fact that we have so many processes in house it allows us to do the entire project (or a large piece of it) saving the customer the time and inefficiencies of utilizing several companies.

Metal Materials handled include cast and stainless steel, cast aluminum, brass, bronze, copper, alloys, cast iron. Turning, milling and short run prototyping services are available.Plastic Materials handled include laminates, phenolic, glass, fishpaper, vulcanized fibre, Nomex®, Mylar®, nylon, acetyl, UHMW, PTFE, glass polyester, acrylic, polycarbonate and refractory materials.

5.What types of materials are you most experienced at machining?

We are most experienced at machining aluminum alloys. We do have some experience in nickel based alloys such as titanium，magnesium and inconel.

---

6.Can you provide design and engineering services or do you just produce parts to customer determined specifications?

We are happy to take either approach. We have extensive design and engineering capabilities. We can start with your idea or casual drawing and ultimately produce parts or assemblies to your satisfaction.

---

7.What are your machining cost?

Rates vary with process and we employ many processes at PTJ. Basing part or project costs on factory rates assumes all similar factory operate at same level of productivity employing the same level of employees and equipment. Certainly that is not the case. We prefer to provide pricing upon detailed review of your Drawings. This approach is much more valuable to the customer.

8.What is your typical turnaround time on an average project?

Average is difficult to define given the diverse nature of materials and processes utilized at PTJ. We consider ourselves as a "Quick Turn&Milling" operation. Often providing much shorter lead times than typical industrial cutting or machining operations. Additionally giving the fact that we have so many processes in house it allows us to do the entire project (or a large piece of it) saving the customer the time and inefficiencies of utilizing several companies.
Depending on the part complexity and capacity of our company typical lead times range from 2-6 weeks after receipt of order.
