The latest development of the Cincinnati Precision Lathe Co., Fosdick Bldg., Cincinnati, Ohio, is a bench lathe equipped with a swivel-head which can be located at any angle with relation to the ways of the bed. This machine, a general view of which is shown in Fig. 1, has a friction drive similar to the one employed on this company's precision bench lathe which was illustrated in the department of New Machinery and Tools for May, 1912. The swivel-head has angular graduations on the base for setting it in any required position, and it is securely held by an eccentric bolt at the left end and a hardened bolt at the front or right end. The position of the head Is accurately maintained by a hardened and ground circular ring inserted in the upper base and fitting closely in a circular slot in a plate that is bolted to the lathe bed. This swivel-head, in conjunction with a combination external and internal tool-post grinder and a double swivel slide-rest, makes the machine a universal precision grinder and lathe.
Fig. 1 shows the position of the headstock and slide-rest for face grinding. The head is set at an angle of 30 degrees, and each swivel rest is also set to the 30-degree position, thus giving a total angle of 90 degrees. Fig. 2 shows the machine arranged for angular grinding, the operation in this case being that of truing the lathe center. Fig. 3 is a rear view of a lathe equipped with a standard head and serves to show spindle. The application of this device makes a countershaft unnecessary for operating the lathe. For the operation of a grinder, a combination countershaft for the lathe and grinder is employed. |
