Workholding specialist Leader Chuck Systems now offers an extensive range of oil country chucks from Polish workholding manufacturer, Bison-Bial. The Tamworth-based company is responsible for the sale of Bison’s extensive cost-effective product range in the UK, which includes pre-sales technical support, stocks of popular items and spare parts being held at Leader’s dedicated logistics facility in Leamington Spa.
Industry-specific products like the oil country chucks designed and produced by Bison provide focused workholding solutions, and highlight how the company listens to its customers and develops robust and efficient answers to the manufacturing problems they face. These high-quality oil country chucks are ideally suited to the oil, gas and petrochemical industry sectors for customers with demanding workholding applications. The extensive range of large through-hole chucks provides a solution for any manufacturer turning long, large diameter parts.
Mark Jones, Leader Chuck Systems’ managing director, says: “Heavy-duty oil country chucks are designed as an addition to the Bison chuck range. The chucks are dedicated to finishing, medium duty and heavy duty machining applications. Bison oil country chucks are available to suit most spindle mount designs and the most popular sizes are stocked in our warehouse.”
Like all chucks from Bison, the oil country chucks are made from forged steel or cast iron. And, all of the working surfaces are induction hardened and ground to ensure that the finished product is a rugged chuck that meets high sliding, stability, and durability parameters that customers have come to expect from the company.
All of the 3-jaw self-centring chucks can work individually or in pairs, mounted on opposite sides of the lathe spindle, ensuring the same vertical position of the jaws in both chucks. This allows the accurate turning of very long components such as pipes.
The cast iron bodied Type 3295 3-jaw self-centring chuck offers a large through-hole compared to the outside diameter of the chuck body. Chuck body sizes are 400, 500, 660 and 800mm diameter with the ability to hold parts from 168 up to 566mm diameter. Maximum operational speeds range from 500rpm down to 200rpm for the largest chuck.
Providing increased rigidity and greater wear resistance, the steel bodied Type 3597 provides higher gripping forces and can withstand increased machining forces. This allows the chuck to operate at between 2,500rpm and 700rpm for the 315 and 800mm diameter chucks respectively, with the bore through ranging from 145 to 460mm diameter.
Also employing a steel body, the extensive heavy-duty Type 3515 HD range supports through-hole, face and internal fixturing for all turning applications. Available in 400, 500, 630 and 800mm diameter the chucks can hold parts between 25 and 800mm diameter. The gripping force ranges from 6,200daN for the smallest chuck up to 9,000daN for the largest, and the maximum operating speed is 1,400 and 600rpm respectively.
All of the heavy-duty 4-jaw independent chucks feature forged steel bodies and can work individually or in pairs, mounted on opposite sides of the lathe spindle, ensuring the same vertical position of the jaws in both chucks. This allows high gripping forces and the accurate turning of very long components such as pipes, flanges, valve bodies and long prismatic parts.
